Answer:

The slope-intercept form is one way to write a linear equation (the equation of a line). The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It's usually easy to graph a line using y=mx+b.

Answer: this is the distance formula.

Step-by-step explanation:

you don’t solve it, it’s a formula for points on a coordinate plane. For example, (1,0) and (2,1). It would be the square root of (1-2)^2 + (0-1)^2. Then you solve it to find the distance.

Answer: Third circle.

Step-by-step explanation:

f(x) = 2ˣ + 3

the function 2ˣ is an exponential graph which range is all real numbers over 0.

Knowing this, by adding a +3, this graph shifts upward by 3 and as such the range shifts to all real numbers over 3.

Answer:

Third option "...greater than 3"

Step-by-step explanation:

The domain of the function for "x" is all real numbers, the range starts from real numbers greater than 3

Answer:

Step-by-step explanation:

First, let's convert all mixed fractions into decimals.

Hence, the solution to the multiplication problem is 5/6.

Answer:

[tex]2 \frac{1}{2} \times \frac{1}{3} [/tex]

[tex]= \frac{2 \times 2 + 1}{2} \times \frac{1}{3} [/tex]

[tex] =\frac{4 + 1}{2} \times \frac{1}{3} [/tex]

[tex]= \frac{5}{2} \times \frac{1}{3} [/tex]

[tex] =\frac{5 \times 1}{2 \times 3} [/tex]

[tex] =\frac{5}{6} [/tex]

The area of the shaded part is: 42.14 ft² .

Area = s²

Area = 1/4πr²

Thus:

Area of the shaded part of the figure = area of square - area of quarter circle

Area of shaded part = s² - 1/4πr²

s = 14 ft

r = 14 ft

Substitute

Area of shaded part = 14² - 1/4(3.14)(14²)

= 42.14 ft²

Therefore, the area of the shaded part is: 42.14 ft² .

Using the figures in the table, we start by calculating the time spent by each of them.

So, we have:

[tex]Mark = 2\frac 16 + 1\frac 56 + 3\frac 34 + 2\frac 18 + \frac 56[/tex]

Adding the fractions, we have:

[tex]Mark = 10 \frac{17}{24}[/tex]

Also, we have:

[tex]Dianne =2\frac 12 + \frac 56 + 3 \frac 23 + 3\frac 23 + \frac 34[/tex]

[tex]Dianne =11\frac 5{12}[/tex]

By comparison:

[tex]11\frac 5{12}[/tex] is greater than [tex]10\frac{17}{24}[/tex];

Answer:

  Diane spent more time studying

Step-by-step explanation:

In general, the question can be answered a couple of ways:

Here, the fractions with different denominators tend to make it easier to use the latter approach.

Either way, the fractions are summed by expressing them using a common denominator. The denominators of 2, 3, 4, 6, and 8 are all factors of 24, so it is convenient to express all of the fractions using 24 as a denominator.

Mark's total time for the week is ...

  (2 1/6) +(1 5/6) +(3 3/4) +(2 1/8) +(5/6)

  = (2 +1 +3 +2 +0) +(1/6 +5/6 +3/4 +1/8 +5/6)

  = 8 +(4/24 +20/24 +18/24 +3/24 +20/24)

  = 8 +(4 +20 +18 +3 +20)/24 = 8 +65/24 = 8 +2 17/24

  = 10 17/24 . . . hours

__

Diane's total time for the week is ...

  (2 1/2) +(5/6) +(3 2/3) +(3 2/3) +(3/4)

  = (2 +0 +3 +3 +0) +(1/2 +5/6 +2/3 +2/3 +3/4)

  = 8 + (12/24 +20/24 +16/24 +16/24 +18/24)

  = 8 +(12 +20 +16 +16 +18)/24 = 8 +82/24 = 8 +3 10/24

  = 11 5/12 . . . hours

At 11 5/12 hours for the week, Diane's total is greater than Mark's total of 10 17/24 hours for the week.

  Diane spent more time studying by the end of the week.

Answer:

able to be believed; convincing. hope this helped

Answer and Step-by-step explanation:

I'm not sure what was in the video, but I do know what this word means.

I would say that usually something that is credible is typically something like an ad. Usually in ads people to to convince and persuade someone to buy or do something that will promote something to happen, usually by buying a company's product.

When evaluating a source, it is important to look for things that indicate whether or not a source is something persuasive, and who the audience of this source is for. For example, if most of a source is opinionated, then it is probably a credible source that is trying to make you buy something.

So, if you are researching an article or information topic, it is important to look for the clues of a source being credible, as I mentioned above.

Once more, I'm not too sure what was in the video, but I hope this helps.

Answer:

20 miles

Step-by-step explanation:

[tex]\frac{Miles}{gallons}[/tex]

402/201=2

10 x 2=20

Hence, The Train can go 20 Miles on 10 gallons

Step 1: Find the slope

Slope formula = (y2 - y1) / (x2 - x1)

---You can choose any two points when finding the slope!

Point 1 = (-2,-10)

Point 2 = (-1,-3)

Slope = (-3 - - 10) / (-1 - - 2)

Slope = 7 / 1

Slope = 7

Step 2: Find the y-intercept

Now that we have the slope, we'll plug that and one point into slope-intercept form. Then, we'll solve for b.

Slope-Intercept Form: y = mx + b

---m is the slope, b is the y-intercept

Point = (-1, -3)

Slope = 7

-3 = 7(-1) + b

-3 = -7 + b

b = 4

Step 3: Put it all together

Now that we know the slope and y-intercept, all that's left to do is plug them into slope-intercept form.

Slope-Intercept Form: y = mx + b

Slope = 7

Y-Intercept = 4

Line: y = 7x + 4

Correct Answer: A

Answer:

The standard deviation of the data set is [tex]\sigma=10[/tex]

Step-by-step explanation:

The formula for standard deviation is [tex]\sigma=\sqrt{\frac{1}{N}\sum_{n=1}^{\infty}(x_i-\mu)^2 }[/tex] where you are basically taking the mean of the data set ([tex]\mu[/tex]), find the mean of the squared differences from the observed values and mean ([tex](x_i-\mu)^2[/tex]), and square root the result:

Mean:

[tex]\mu=\frac{36+18+12+10+9}{5}=\frac{85}{5}=17[/tex]

Average of squared differences (variance):

[tex]\frac{1}{N}\sum_{n=1}^{\infty}(x_i-\mu)^2=\frac{(36-17)^2+(18-17)^2+(12-17)^2+(10-17)^2+(9-17)^2}{5}=\frac{500}{5}=100[/tex]

Standard deviation:

[tex]\sigma=\sqrt{100}=10[/tex]

This means that the standard deviation of the data set is 10, which tells us that the values of the data set, on average, are separated by 10.

Remember that the domain is all possible x values of a function. In the case of sine and cosine functions, they go up and down (like waves), but go on forever. Therefore, the domain is all real numbers.

Correct Answer: B, All Real Numbers

Hope this helps!

Explanation:

For the equations y = sin(x) and y = cos(x), we can replace x with any real number we want. The output y value will be between -1 and 1, inclusive of both endpoints.

The graph for each function shows a bouncing wave stretching forever to the left and right. This visually confirms the domain.
