Enter the difference between the rates of change for these two functions.
Alchen [17]

Answer:

.

Step-by-step explanation:

Graph :

Choose any two points. (0 , 2) and (-1 , -2)

Rate of change = Change in y ÷ Change in x

                          = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=  \frac{-2 - 2}{-1 - 0}\\\\=  \frac{-4}{-1}\\\\= 4

Table:

Rate of change = \frac{-2-[-6]}{2-0}

                          =  \frac{-2+6}{2}\\\\=  \frac{4}{2}\\\\= 2

A gift box is the shape of a rectangular prism. The box has a length of 24 centimeters, a width of 10 centimeters, and a height
Kamila [148]
Volume (V) is (=) Length (L) times (x) Width (W) times (x) Height (H) so V = L x V x H. 

Add the variables to the equation.
V = 24 x 10 x 13

Solve
V = 3120

So the volume of the gift box is 3120 cm
