The center of the dilation is the origin, and the scale factor is 2.
To find the coordinates of the points under this transformation, it is enough to multiply both coordinates of the points X, Y, and Z by 2.
Take a look at the dilation of point Z. To get to Z', both the x and y coordinate of Z must be multiplied by 2.
So, the coordinates are:
X'(8, 0); Y'(6, 4); Z'(4, -4).
Answer:
3m - 4
Step-by-step explanation:
Divide.
(15mn)/(5n) = 3m
(-20n)/(5n) = -4
3m - 4 is your answer.

Answer:
16
Step-by-step explanation:
To solve, we can use an equation finding the average of the siblings'ages.

When simplified the answer is -2n^3+13
The volume of the sphere is 1437.33 ft³
<h3>
</h3><h3>What is volume of sphere?</h3>
A sphere's volume V is four-thirds of pi times the radius cubed. A hemisphere's volume is half of the volume of the associated sphere.
The volume of a spherical.
V= 4/3 πr³
radius= 7ft
So,
V= 4/3*22/7*7*7*7
V= 30184/21
V = 1437.33 ft³
