Answer:

(A)g(x)=\dfrac{1}{2}(x-8)^2-8

(h,k)=(8,-8)

Step-by-step explanation:

(A)g(x)=\dfrac{1}{2}(x-8)^2-8\\(B)g(x)=\dfrac{1}{2}(x-12)(x-4)\\(C)g(x)=\dfrac{1}{2}x^2-8x+24

From the given equivalent forms of the function g(x), we are to pick which form quickly reveals the vertex.

The vertex form of a parabola is given: f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Therefore, Option A, (A)g(x)=\dfrac{1}{2}(x-8)^2-8 quickly reveals the vertex.

From the above, h=8, k=-8. Therefore the vertex (h,k)=(8,-8)

A hot air balloon descends at a rate of 320 feet per minute for 3 minutes. Use integers to calculate and
Amanda [17]
Given:
descends at a rate of 320 feet per minute for 3 minutes.

320 feet per minute * 3 minutes = 960 feet

Total change in altitude is 960 feet. Since it is descending, I believe it would be a negative 960 feet.
