Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y=
21(0.97)
^x

see explanation

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

answer: #1 ads up by 8 and i don't know #2

55 degrees because 55+55=110 degrees
