Answer 1

Answer:

angle a: 70°

angle d: 70°

angle dce: 35°

x: 15m

y: 14m

Step-by-step explanation:

all triangles add to 180° so 35 + 75 = 110 and 180-110 = 70

where the two triangles connect and cross, the angles will be the same so it will have the same angle measures as the first triangle which makes the triangles similar

knowing that they are similar triangles will help with figuring out the lengths of the sides.

since they are similar, their sides will be proportional, we just need to figure out the ratio

if we lay the triangles on top of each other, the two 75° angles match up and therefore the sides do too so we can make a fraction 12/18 = 10/x

now we can solve for x

multiply both sides by x

12x/18 = 10

now multiply both sides by 18

12x = 180

divide both sides by 12

x = 15

now we do the same for y

12/18 = y/21

12*21/18 = y

y = 14

hope this helps!

Step-by-step explanation:

Answers

The domain are the possible input while the range are the possible output of a function.

(a) The domain = [-√2, √2], the range = [0, 2]

(b) The domain = [-1, 1], the range = [0, 1]

(c) The domain = [-1, 1], the range = [0, -1]

(d) The domain = [0, 2], the range = [0, 1]

(e) The domain = [-(2 + √2), (√2 - 2)], the range = [0, 2]

Reasons:

The given functions can be expressed by the equation; (-x + 1)·(x + 1) = -x² + 1

Therefore, we have;

(a) y = f(x) + 1 = -x² + 1 + 1 = -x² + 2

The x-intercept of the above function are, x = √2, and x = -√2

Which gives;

The domain = [-√2, √2]

The range = [0, 2]

(b) y = 3·f(x) = 3 × (-x² + 1) = -3·x² + 3

At the x–intercepts, we have;

-3·x² + 3 = 0

x = ±1

The domain = [-1, 1]

The maximum value of y is given at x = 0, therefore;

= -3 × 0² + 3 = 3

The range = [0, 1]

(c) y = -f(x) = -(-x² + 1) = x² - 1

At the x–intercepts, x² - 1 = 0

x = ± 1

The domain = [-1, 1]

The minimum value of y is given at x = 0, which is y = -1

The range = [0, -1]

(d) y = f(x - 1) = -(x - 1)² + 1 = -x² + 2·x

At the x–intercepts, we have;  -x² + 2·x = 0, which gives;

(-x + 2)·x = 0

Which gives, x = 0, or x = 2

The domain = [0, 2]

The maximum value of y is given when x = -b/(2·a) = -2/(2×(-1)) = 1

y = f(1) =  -1² + 2×1 = 1

Therefore;

The range = [0, 1]

(e) y = f(x + 2) + 1 = (-(x + 2)² + 1) + 1 = -x² - 4·x - 2

At the x–intercepts, we have;  -x² - 4·x - 2 = 0, which gives;

x = -(2 + √2) or x = x = √2 - 2

The domain = [-(2 + √2), (√2 - 2)]

The maximum value of y is given when x = -4/(2)) = -2

Which gives;

-(-2)² - 4·(-2) - 2 = 2

The range = [0, 2]

Two planets are orbiting a star. Planet B can be seen from Planet A with the eye, but as the figure shows, Planet could be located at either of two possible positions. Planet A is 65 million miles from the star and Planet B is 45 million miles from the star, as shown in the figure below. If the viewing angle between the star and Planet B is 19 , find the possible distances from Planet A to Planet B . Round your answers to the nearest tenth.

Answers

Answer:

Step-by-step explanation:

Let's call the distance from Planet A to one of the possible positions of Planet B "x". We can use trigonometry to relate the angle between the star and Planet B (19°), the distance from the star to Planet A (65 million miles), and the distances from Planet A to Planet B (x).

In a right triangle with angle 19°, the opposite side is x and the adjacent side is 65 - 45 = 20 million miles. Therefore, we can use the tangent function to relate these sides:

tan(19°) = x / 20

Solving for x, we get:

x = 20 tan(19°) ≈ 6.7 million miles

So one possible distance from Planet A to Planet B is approximately 6.7 million miles.

However, there is another possible position for Planet B, which is on the other side of Planet A as shown in the figure. In this case, the distance from Planet A to Planet B is:

y = 65 + 45 + 20 = 130 million miles

Therefore, the two possible distances from Planet A to Planet B are approximately 6.7 million miles and 130 million miles (rounded to the nearest tenth).

Answers

There are 12 lowercase words of length 8 in which each distinct letter appears exactly twice.

What are the Lowercase Words?

To form a lowercase word of length 8 in which each distinct letter appears exactly twice, we can choose 4 distinct letters from the English alphabet and then arrange them in pairs in the word. The number of ways to choose 4 distinct letters from 26 is:

C(26, 4) = 26! / (4! * 22!) = 14,950

Once we have chosen 4 distinct letters, we can arrange them in pairs in the word in the following way:

Choose the first pair: we can choose any of the 4 letters, so there are 4 options.Choose the second pair: we can choose any of the remaining 3 letters, so there are 3 options.Arrange the pairs: there is only one way to arrange the pairs.

Therefore, the total number of such words is:

4 * 3 * 1 = 12

Answers

A claw arcade machine contains stuffed animals and mystery boxes.

A claw arcade machine is a popular type of game machine found in many arcades and amusement parks. It typically consists of a glass cabinet that contains a variety of stuffed animals and other prizes, such as mystery boxes, that can be won by using a mechanical claw.

The player inserts a designated amount of money and then uses the joystick to position the claw over the desired prize. Once the player is satisfied with the claw's position, they press a button to make the claw descend and attempt to grab the prize. If the claw is successful in grabbing the prize, it will lift it up and drop it into the prize chute, where the player can then collect it.

The prizes in a claw machine can vary from small plush toys to larger stuffed animals, and even mystery boxes that contain unknown items or a chance to win a bigger prize. The claw's strength and grip are adjustable, which can make winning a prize more difficult or easier depending on the machine's settings.

Claw machines are a popular form of entertainment for all ages, and the thrill of successfully grabbing a coveted prize can be a source of excitement and satisfaction for players.

Si una pelota más un bate cuesta 1.10 dólares su precio del bate es 1 dólar más que la pelota cuánto cuesta el bate.cuánto cuesta el bate?

Answers

Answer:

Step-by-step explanation:

If a ball plus a bat costs 1.10 dollars and the price of the bat is 1 dollar more than the ball, what is the cost of the bat?

If we represent the price of the ball as "p", then the price of the bat will be "p + 1", since the problem tells us that the price of the bat is 1 dollar more than the price of the ball.

We also know that the sum of the price of the ball and the bat is 1.10 dollars. We can write this as an equation:

p + (p + 1) = 1.10

Simplifying and solving for p, we get:

2p + 1 = 1.10

2p = 0.10

p = 0.05

Therefore, the price of the ball is 0.05 dollars. To calculate the price of the bat, we can add 1 dollar to the price of the ball:

p + 1 = 0.05 + 1 = 1.05

So, the price of the bat is 1.05 dollars.

Find the perimeter of the triangle whose vertices are (−3,5)
, (−3,2)
, and (−1,−3)
. Write the exact answer. Do not round.

Answers

The exact perimeter of the triangle is: 8+3√17 units.

what is perimeter ?

Perimeter is the total distance around the boundary of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape. For example, the perimeter of a rectangle is found by adding the length of all four sides, while the perimeter of a circle is the distance around the circle. Perimeter is typically measured in units such as centimeters, meters, feet, or miles.

Given by the question:
The distance formula between two points (x1, y1) and (x2, y2) is:

[tex]d = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]

So, to find the lengths of the sides of the triangle with vertices (-3, 5), (-3, 2), and (-1, -3), we can use the distance formula as follows:

Between (-3, 5) and (-3, 2):

[tex]d =\sqrt{[(y2 - y1)^2 + (x2 - x1)^2]}[/tex]

= [tex]\sqrt{[(2 - 5)^2 + (-3 - (-3))^2]}[/tex]

= [tex]\sqrt{[(-3)^2 + 0^2]}[/tex]

= [tex]\sqrt{9}[/tex]

= 3

Between (-3, 2) and (-1, -3):

[tex]d = \sqrt{[(y2 - y1)^2 + (x2 - x1)^2]}[/tex]

= [tex]\sqrt{[(-3 - 2)^2 + (-1 - (-3))^2]}[/tex]

= [tex]\sqrt{[(-5)^2 + 2^2]}[/tex]

= [tex]\sqrt{29}[/tex]

Between (-1, -3) and (-3, 5):

[tex]d = \sqrt{[(y2 - y1)^2 + (x2 - x1)^2]}[/tex]

= [tex]\sqrt{[(5 - (-3))^2 + (-3 - (-1))^2]}[/tex]

= [tex]\sqrt{[8^2 + (-2)^2]}[/tex]

= [tex]\sqrt{68}[/tex]

Now we can add up the lengths of the sides to get the perimeter:

[tex]P = 3 + \sqrt{29} + \sqrt{68}[/tex]

So the exact perimeter of the triangle is:

8 + 3√17 units.

Estimate by rounding 938,617 and 254 to the nearest hundred, and then find the difference. Write the number name for the difference.

Answers

Answer:

Estimate of 938,617 - 254 is  938, 300

Step-by-step explanation:

To round to the nearest hundred we look at the digit in the hundreds place and examine the digit to the right of it. If the digit to the right of the 100's place is 5 or greater round the hundreds digit up, else leave it as is. Make all the digits to the right of the 100's digit zeros

938,617 rounded to the nearest 100 is 938,600
The 6 in the hundreds place stays the same, because the digit to the right in the tens place is 1 which is less than 5

254 rounded to 100's place = 300
The digit in the 100's place is 2; the digit to the right of it is 5 so round 2 to 3 and make all digits to its right as 0

Estimate of 938,617 - 254 = 938,600 - 300 = 938, 300

Actual value of 938,617 - 254 = 938,363 so we are off by only a small margin

A rectangle that is 9 meters long has an area of 36 square meters what is the perimeter

Answers

Answer:

the perimeter of the rectangle is 26 meters.

Step-by-step explanation:

To find the perimeter of the rectangle, we need to know its width. We can find the width by dividing the area by the length:

width = area / length = 36 / 9 = 4 meters

Now we can use the formula for the perimeter of a rectangle:

perimeter = 2(length + width)

Substituting the given values, we get:

perimeter = 2(9 + 4) = 2(13) = 26 meters

Therefore, the perimeter of the rectangle is 26 meters.

Ashley has a deck that measures 12 feet by 10 feet. She wants to increase each dimension by equal lengths so that its area is tripled. By how much should she increase each dimension?

Answers

If Ashley has a deck that measures 12 feet by 10 feet. Ashely should  increase each dimension by 8feet.

How to find the dimension?

The original area of the deck is:

12 feet x 10 feet = 120 square feet

To triple this area, Ashley needs to increase the area by a factor of 3. That means the new area should be:

3 x 120 square feet = 360 square feet

Let's say Ashley increases the length and width of the deck by x feet. The new dimensions of the deck will be:

(12 + x) feet by (10 + x) feet

The new area of the deck will be:

(12 + x) feet x (10 + x) feet = 120 + 22x + x^2 square feet

We want this area to be 360 square feet, so we can set up the equation:

120 + 22x + x^2 = 360

Simplifying this equation, we get:

x^2 + 22x - 240 = 0

We can solve this quadratic equation by factoring:

(x + 30)(x - 8) = 0

The solutions are x = -30 and x = 8, but we can discard the negative solution since we are looking for a positive increase in dimension.

Therefore, Ashley should increase each dimension by 8 feet in order to triple the area of her deck.

18.) 19 - 3x = 14 + 2x
19.) 2(7 + 5y) - 3y = -35
20.) 14 + 4(x - 5) = 6 - 2x​

Answers

Answer:

Step-by-step explanation:

18.) 19 - 3x = 14 + 2x

To solve for x, we can simplify the equation by moving all the x terms to one side and all the constant terms to the other side:

19 - 3x = 14 + 2x

19 - 14 = 2x + 3x

5 = 5x

x = 1

To check our solution, we can substitute x = 1 back into the original equation and see if it holds true:

19 - 3(1) = 14 + 2(1)

19 - 3 = 14 + 2

16 = 16

Since both sides of the equation are equal when x = 1, we have verified that x = 1 is the correct solution.

19.) 2(7 + 5y) - 3y = -35

We can start by simplifying the left-hand side of the equation by using the distributive property:

2(7 + 5y) - 3y = 14 + 10y - 3y = 14 + 7y

Now, we can solve for y by moving the constant term to the other side:

14 + 7y = -35

7y = -49

y = -7

To check our solution, we can substitute y = -7 back into the original equation and see if it holds true:

2(7 + 5(-7)) - 3(-7) = -35

2(7 - 35) + 21 = -35

-56 + 21 = -35

-35 = -35

Since both sides of the equation are equal when y = -7, we have verified that y = -7 is the correct solution

20.) 14 + 4(x - 5) = 6 - 2x

We can start by simplifying the left-hand side of the equation by using the distributive property:

14 + 4(x - 5) = 14 + 4x - 20 = 4x - 6

Now, we can solve for x by moving the constant term to the other side:

4x - 6 = 6 - 2x

6x = 12

x = 2

To check our solution, we can substitute x = 2 back into the original equation and see if it holds true:

14 + 4(2 - 5) = 6 - 2(2)

14 - 12 = 6 - 4

2 = 2

Since both sides of the equation are equal when x = 2, we have verified that x = 2 is the correct solution.

Identify a sequence of transformations that maps triangle ABC onto triangle A”B”C” in the image below

Answers

The sequence of transformations that maps triangle ABC onto triangle A”B”C” is: First the triangle is rotated by 90 degrees thus following the transformation rule (x, y) → (y, -x) and then dilation.

What is dilation?

The scale factor is defined as the difference in size between the new and old images. An established location in the plane is the centre of dilatation. The dilation transformation is determined by the scale factor and the centre of dilation.

The image stretches when the scaling factor exceeds 1.

When the scale factor is between 0 and 1, the image gets smaller.

The resulting image and the original image are identical if the scale factor is 1.

The coordinates of the triangle ABC are:

A(0, -1)

B (0, 1)

C (0, 1.8)

First the triangle is rotated by 90 degrees thus following the transformation rule:

(x, y) → (y, -x)

The new coordinates are:

A(0, -1) → A (1, 0)

B (0, 1) → B (-1, 0)

C (0, 1.8) → C (1.8, 0)

Then, the rotated figure is dilated using a scale factor of:

SF = 6/2 = 3

Hence, the sequence of transformations that maps triangle ABC onto triangle A”B”C” is: First the triangle is rotated by 90 degrees thus following the transformation rule (x, y) → (y, -x) and then dilation.

Write an equation for the line in slope-intercept form.

Answers

When the coordinate is (-3, -3) and the slope is -1, the y-intercept is -4.

What is slope?

Slope is a measure of the stainless of a line what is surface and it represent by the letter m. It is calculated by dividing the vertical change in the line or surface by the horizontal change in the line or surface. Slope is used in mathematics engineering and other science to measure the rate of change between two point.

The y-intercept is the point at which a line crosses the y-axis when plotting coordinates on a graph. To find the y-intercept, you need to use the equation y = mx + b, where m is the slope and b is the y-intercept. In this case, the equation would be y = -1x - 4. This equation can be used to solve for the y-intercept when the coordinate is (-3, -3). By substituting -3 for x and -3 for y, the equation can be rearranged to -3 = -1(-3) - b, which simplifies to -4 = -b. Therefore, the y-intercept is -4.

The mean and standard deviation of a population are 200 and 20, respectively. Sample size is 25. What is the mean of the sampling distribution?.

Answers

The mean of the sampling distribution is 200, and the standard deviation of the sampling distribution is 4.

The sampling distribution is a theoretical distribution that represents the behavior of sample means from all possible samples of a given size that can be drawn from a population.

However, the standard deviation of the sampling distribution is not the same as the standard deviation of the population.

Mathematically, we can represent the mean of the sampling distribution as follows:

μ(x) = μ = 200

Where μ(x) represents the mean of the sampling distribution and μ represents the mean of the population.

We can also calculate the standard error of the mean using the following formula:

σ(x) = σ / √(n)

Where σ(x) represents the standard deviation of the sampling distribution, σ represents the standard deviation of the population, and sqrt(n) represents the square root of the sample size.

Plugging in the values given in the problem, we get:

σ(x) = 20 / √(25) = 4

This is my fourth time posting this, would someone please answer? I'd like some assistance with this question. Why can we only estimate the distances? Please elaborate on the whole thing.

Answers

In many contexts, we can estimate distances between objects or locations, but we may not always be able to measure them precisely. There are several reasons why we might only be able to estimate distances rather than measure them exactly:

Limitations of measuring instruments: The precision of a measuring instrument can limit our ability to measure distances accurately. For example, a ruler may only have markings up to a certain level of precision, so we may need to estimate distances between the markings.

The variability of the distance: In some cases, the distance we are measuring may be constantly changing, making it difficult to measure with precision. For example, if we are trying to measure the distance between two moving objects, the distance between them will constantly change, and we may need to estimate the distance at a particular moment in time.

Environmental factors: The environment can also make it difficult to measure distances precisely. For example, atmospheric conditions such as haze or fog can obscure objects and make it difficult to judge their distance accurately.

Human perception and judgment: Finally, our own perception and judgment can also limit our ability to measure distances accurately. For example, when estimating the distance to an object, our perception of the size of the object can affect our judgment of its distance.

In many cases, despite these limitations, estimates of distances can still be useful and informative. For example, in navigation, we may not need to know the exact distance between two points, but only an estimate that is accurate enough to help us navigate from one point to the other

Unexpected expenses have come up, and you want a cash advance on your credit card (which comes with a transaction fee of 2.5%). The limit on your credit card is $7,500, and you already have a balance of $2,200. What is your available credit? How much will you owe as a transaction fee if you want a cash advance on your available credit??

Please answer correctly and explain your answer…

Answers

To calculate your available credit, you need to subtract your current balance and the amount of cash advance you want from your credit limit:

Available credit = credit limit - current balance - cash advance amount

Given that your credit limit is $7,500 and your current balance is $2,200, the available credit can be calculated as follows:

Available credit = $7,500 - $2,200 - cash advance amount

Now, if you want a cash advance of $1,000, for example, your available credit will be:

Available credit = $7,500 - $2,200 - $1,000 = $4,300

Therefore, your available credit is $4,300 if you want a cash advance of $1,000.

To calculate the transaction fee, you need to multiply the cash advance amount by the transaction fee percentage. In this case, the transaction fee is 2.5%. So, if you want a cash advance of $1,000, the transaction fee will be:

Transaction fee = $1,000 x 0.025 = $25

Therefore, if you want a cash advance of $1,000, you will owe a transaction fee of $25. It's important to note that cash advances usually come with a higher interest rate than regular credit card purchases, so it's best to use them only when absolutely necessary and pay them off as soon as possible to avoid accruing interest charges.
