Aperson standing at a ridge in the grand canyon throws a penny upeard and toward the pit of the canyon. the height of the penny is given by the function h(t)=-12t^(2)+80t. what is the maximum height that the penny will reach?

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

a is the right answer
