Use the formula S A = 6s2 , where S A is the surface and s is the edge length of the cube , to solve his problem.
Gennadij [26K]
To find the surface area of the cube using the formula, you would substitute in 2 1/2 for the length of the side.

SA = 6 x 2.5 x 2.5
SA = 37.5 ft.²

You are finding the area of one face (2.5 x 2.5) and multiplying it by six because there are six groups of this.

HELP!!!
Anuta_ua [19.1K]

Answer:

\$77,000 and the graph would fall at a slower rate to the right

Step-by-step explanation:

we have

y=Ao(0.79)^{x}

Observing the graph

The initial value Ao of the truck is equal to the y-coordinate of the y-intercept of the graph

so

Ao=\$77,000

If the depreciation rate was 15% per year, the new formula would be

y=Ao(1-0.15)^{x}

y=Ao(0.85)^{x}

y=77,000(0.85)^{x} ----> the graph would fall at a slower rate to the right

using a graphing tool

compare the graphs
