Answer:
A
Step-by-step explanation:
The sequence of payment is geometric , that is
1, 3, 9, ...
The sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
Here a = 1 and r = 3 ÷ 1 = 3 , then
= = = = 7174453 cents and
7174453 ÷ 100 = $71,744.53 → A
C
B, f(x) = ( x+2) ^2(x-1) (x+3)
Looking at the x- intercepts, the line passes at 2, -1, and 3, so B is you answer (:
k+7
because k is the age of kit so Anika is 7 years older, so u have to add
sorry if I'm wrong
