An online retailer developed two exponential functions to model the weekly usage of two coupon codes where x is the number of weeks since the start of the year. The equation represents the weekly usage of code 1, and the table represents the weekly usage of code 2.
your answer is a
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

a^2+b^2=c^2 so first ac
acm is a right triangle because c= 90°
and am (the hypotenuse or c) =16+9 =25
but there is not enough info we need another angle or side length
