what is the average rate of change from x = -4 to x = 4 for the graphed exponential equation:

-5/8

Step-by-step explanation:

Rate of change will be given by the gradient of the graph between the given intervals

For x = -4 we have the point, (-4,  0)

For x = 4 we have the point, (4, -5)

Gradient = change in y /change in x

               = (0 - -5)/(-4 - 4)

                = 5/-8

                = -5/8

The average rate of change = -5/8

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
