Answer:
Step-by-step explanation:
7.2^6
Discriminant b^2-4ac = (-9)^2 - 4*2*9 = 9
so there are 2 roots
because of the -9x and 9 they will both be positive
Answer:
$57.52 I believe that is the correct answer.
A.
A = 400 (1 + (0.02)/4)^4t where t = number of years and A = amount after t years
simplifying that becomes
A = 400 (1.005)^4t
b amount after 5 years is
400 (1.005)^(4*5) = 400 (1.005)^20 = $ 441.96
