Answer:

srt is 33

srq is 66

trq is 33

Answer:

∠SRT = 33°

Step-by-step explanation:

To track what angle they're talking about, connect the letters listed for each angle like connect the dots.

∠QRT is 33°

RT bisects ∠SRQ, meaning it's in the middle of it.

So half of ∠SRQ is 33°, meaning the full angle is double that: 66°

That also means that the other half of the angle is equal to the first half. ∠SRT=33°

[tex]\textsf{Slope of Function A = 2 x Slope of Function B}[/tex]

Step-by-step explanation:

We know that Function A is given by:

[tex]f(x)=6x-1[/tex]

And we are given the graph of Function B.

And we are asked to compare the slopes of the two functions.

So, we will determine the slope of each.

For Function A, the slope is simply the coefficient of our independent variable x.

Since 6 is our coefficient, the slope of Function A is 6.

For Function B, we will utilize the slope formula, given by:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We will need any two points from our graph. Let’s use (0, 1) and (-1, -2).

So, we will let (0, 1) be (x₁, y₁) and (-1, -2) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{-2-1}{-1-0}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{-3}{-1}=3[/tex]

So, the slope of Function B is 3.

Therefore, the slope of Function A is twice the slope of function B.

So, we can write that:

[tex]\textsf{Slope of Function A = 2 x Slope of Function B}[/tex]

Answer: The expected value is $0.32

Step-by-step explanation:

The expected value can be calculated as:

EV = ∑xₙ*pₙ

Where:

xₙ is the n-th event.

pₙ is the probability of the n-th event.

First, let's see the events in this situation and the probability of each event.

Lossing $1.

This happens when you roll all different numbers.

To calculate the number of combinations where you roll all different values, we first need to count the number of possible options for each roll, this is:

First dice: you have 6 options

Second dice: You have 5 options, because we remove the option that was rolled in the first dice.

Third dice: You have 4 options, because we removed the two outcomes showed in the two previous rolls.

Then the number of combinations is:

c = 6*5*4 = 120.

And the total number of combinations for rolling 3 dice is equal to the product between the number of outcomes for each dice, each dice has 6 possible outcomes, then the total number of outcomes is:

C = 6*6*6 = 216

The probability of rolling all different numbers will be equal to the quotient between the number of combinations where you roll all different values and the total number of combinations:

P₁ = 120/216 = 0.56

In the other case, where you roll at least two equal outcomes, you win $2.

The probability for this case will be the complement of the previous one, then the probability can be calculated as:

P₂ = 1 - P₁ = 1 - 0.56 = 0.44

Then the expected value will be:

EV = -$1*0.56 + $2*0.44 =  $0.32

The expected value is $0.32

Answer:

[tex]y = 3.5x[/tex]

Step-by-step explanation:

Required

Determine the equation

First, pick corresponding x and y values

[tex](x_1,y_1) = (6,21)[/tex]

[tex](x_2,y_2) = (14,49)[/tex]

Next, calculate the slope

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives:

[tex]m = \frac{49 - 21}{14 - 6}[/tex]

[tex]m = \frac{28}{8}[/tex]

[tex]m = 3.5[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 21 = 3.5(x - 6)[/tex]

[tex]y - 21 = 3.5x - 21[/tex]

Add 21 to both sides

[tex]y - 21+21 = 3.5x - 21+21[/tex]

[tex]y = 3.5x[/tex]

Answer:

The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2) ⇒ D

Step-by-step explanation:

To solve this type of question, Form the equation of the line and substitute the x-coordinate of each ordered pair to find y, if the value of y equal to the value of the y-coordinate of the point, then the point is on the line

The form of the linear equation is y = m x + b, where

From the given figure

∵ The line passes through points (-4, 0) and (0, 4)

∴ x1 = -4 and y1 = 0

∴ x2 = 0 and y2 = 4

→ Substitute them in the rule above

∵ m = [tex]\frac{4-0}{0--4}[/tex] = [tex]\frac{4}{0+4}[/tex] = [tex]\frac{4}{4}[/tex]

∴ m = 1

∵ b is the value of y at x = 0

∵ y = 4 at x = 0

∴ b = 4

→ Substitute the values of m and b in the form of the equation above

∴ y = 1(x) + 4

∴ y = x + 4 ⇒ equation of the given line

Let us check every group

∵ The ordered pairs are (7, 3), (6, 2), (2, -2)

∵ y = x + 4

∵ x = 7

∵ y = 7 + 4 = 11

∵ y-coordinate = 3

∴ Point (7, 3) doesn't lie on the line

∵ The ordered pairs are (5, 1), (3, 7), (2, 6)

∵ x = 5

∴ y = 5 + 4 = 9

∵ y-coordinate = 1

∴ Point (5, 1) doesn't lie on the line

∵ The ordered pairs are (3, 7), (2, 6), (2, 2)

∵ x = 3

∴ y = 3 + 4 = 7

∵ y-coordinate = 7

∴ Point (3, 7) lies on the line

∵ x = 2

∴ y = 2 + 4 = 6

∵ y-coordinate = 6

∴ Point (2, 6) lies on the line

∵ x = 2

∴ y = 6

∵ y-coordinate = 2

∴ Point (2, 2) doesn't lie on the line

∵ The ordered pairs are (3, 7), (2, 6), (-2, 2)

∵ x = 3

∴ y = 3 + 4 = 7

∵ y-coordinate = 7

∴ Point (3, 7) lies on the line

∵ x = 2

∴ y = 2 + 4 = 6

∵ y-coordinate = 6

∴ Point (2, 6) lies on the line

∵ x = -2

∴ y = -2 + 4 = 2

∵ y-coordinate = 2

∴ Point (-2, 2) lies on the line

∵ The three ordered pairs lie on the line

∴ The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2)

∵ The ordered pairs are (1, 5), (-6, 2), (-7, -3)

∵ x = 1

∴ y = 1 + 4 = 5

∵ y-coordinate = 5

∴ Point (1, 5) lies on the line

∵ x = -6

∴ y = -6 + 4 = -2

∵ y-coordinate = 2

∴ Point (-6, 2) doesn't lie on the line

Answer:

Border should be 1 ft wide

Step-by-step explanation:

The pool is 10 feet long and 6 feet wide.

Now, since the landscape contractor wants to make an exposed gravel border of uniform width. Let the uniform width of the border be x. Thus it means the length is now (10 + 2x) and width is now (6 + 2x).

We are told there is enough material to cover 36 square feet.. Thus;

New area - old area = 36

[(10 + 2x) × (6 + 2x)] - (10 × 60) = 36

4x² + 32x + 60 - 60 = 36

4x² + 32x = 36

Subtract 36 from both sides to get;

4x² + 32x - 36 = 0

Using quadratic formula, we have;

x = -9 or 1

We will pick the positive value as the width can't be negative.

Thus;

x = 1 ft

Answer:

The area of the circle is [tex]\mathbf{6.25\pi}[/tex]

Step-by-step explanation:

Area of a Circle

A circle of radius r has an area calculated by the following formula:

[tex]A=\pi r^2[/tex]

The diameter of a circle is twice the radius, thus the radius is half the value of the diameter.

A given circle has a diameter of 5 inches.

The radius of this circle is r = 5/2 = 2.5 inches.

Thus, the area is calculated below:

[tex]A=\pi 2.5^2 = 6.25\pi[/tex]

The area of the circle is [tex]\mathbf{6.25\pi}[/tex]

Answer:

A= –5x2 + 4x – 7y + 14 = 0

C= 9x2 – 12xy + 4y2 + 4x – y + 5 = 0

D= 12x + 6y – 5y2 + 14 = 0

Step-by-step explanation:

I finished the assignment from Edge2020

The equation which would produce a parabola from the provided options are equation first and forth,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

[tex]12x + 6y -5y^2 + 14 = 0[/tex]

To of identify the type of conic section from an equation whether it is parabola, or not, let suppose the equation as,

[tex]Ax^2+By^2+Cx+Dy+E=0[/tex]

If In this equation,

Either [tex]A=0[/tex] or [tex]B=0[/tex], but not both. Then it is the equation of parabola.

The first equation is,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

There is no square term of y. Thus, this is the equation of parabola.

The second equation is,

[tex]-x^2 + 6x + y^2 - 8 = 0[/tex]

This is not the equation of parabola, as there is two square terms of variable x and y.

The third equation is,

[tex]9x^2 - 12xy + 4y^2 + 4x - y + 5 = 0[/tex]

Similar to the second equation, here is also two square terms of different variable. Thus, it is not a equation of parabola.              

The fourth equation is,

[tex]12x + 6y -5y^2 + 14 = 0[/tex]

This equation is the equation of parabola, as there is only a single square term.

The fifth equation is,

[tex]20x^2 + 10xy - y^2 + 3x - 6y + 5 = 0[/tex]

This is now the equation of parabola because of two square terms.

Hence, the equation which would produce a parabola from the provided options are equation first and forth,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

[tex]12x + 6y -5y^2 + 14 = 0[/tex]
