x y

1 -9

2 -14

3 -19

4 -24

5 -29

6 -34

Step-by-step explanation:

You're going to have to graph it yourself.

Take the coordinated and just plot the points, then draw the line.

(1,-9)

Identify the volume and surface area of the sphere in terms of π. HELP PLEASE!!

Helen [10]

Answer:

First choice V = 18,432π m^3; S = 2,304π m^2

Step-by-step explanation:

Start with the two formulas:

Volume of a circle:

$V = \dfrac{4}{3} \pi r^3$

Surface area of a circle:

$S = 4 \pi r^2$

Now use r = 24 m in each formula.

Volume:

$V = \dfrac{4}{3} \pi (24~m)^3$

$V = \dfrac{4}{3} \pi (13,824~m^3)$

$V = 18,432\pi~m^3$

Surface area:

$S = 4 \pi r^2$

$S = 4 \pi (24~m)^2$

$S = 4 \pi (576~m^2)$

$S = 2,304\pi ~m^2$

Answer: First choice V = 18,432π m^3; S = 2,304π m^2

Solve for x: 5x+3y=22 y=2x

den301095 [7]

5x + 3y = 22
y = 2x

Substitute y=2x into the first equation

5x + 3(2x) = 22
5x + 6x = 22
11x = 22
x = 2

Hope that helps :)

−4(3m−3)+(−10+8m)=?

Valentin [98]

-4(3m-3)+(-10+8m)
12m+12-1+8m
12m+8m = 20m
+12 -1= +11
answer: 20m+11

*note negative times a negative equals positive and negative times positive is negative
first: you multiply -4 by 3m which is -12m.
second: you multiply -4 by -3 which is +12
third: find the invisible which is 1. (located right here: +(1) (-10+8m)
fourth: multiply invisible 1 by -10 which is -10
fifth: multiply invisible one by +8m which is +8m
sixth: combine like terms
seventh: answer

Triangle XYZ was dilated by a scale factor of 2 to create triangle ACB and cos ∠X = 2.5 over 5 and 59 hundredths. Triangles XYZ

adell [148]

Dilation involves changing the size of a shape

<h3>How to determine the relationship between the trigonometry ratios</h3>

From the question, we understand that:

The dilation of triangle XYZ gives triangle ACB

This means that, the following are corresponding points

Points X and A
Points Y and C
Points Z and B

The above means that:

The relationships between the trigonometry ratios of both triangles are:

cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)

<h3>How to determine the measures of segments AC and AB</h3>

In (a), segments XY and XZ corresponds to the segments AC and AB

So, the product of the lengths of XY and XZ and the scale factor will result in the lengths of AC and AB,

i.e.

AC = 2 * XY and AB = 2 * XZ
