What is h(x) = 7 + 10x + x2 written in vertex form? A:h(x) = (x - 25)^2 – 18
B:h(x) = (x - 5)^2 + 32
C:h(x) = (x + 5)^2 - 18
D:h(x) = (x + 25)^2+32

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
