Surface area = 17*(sqrt(1155) + 19)

h^2 = 19^2 - 17^2/4
=> h = sqrt(4*19^2 - 17^2)/2 = sqrt(1155)/2
Surface area = 4(1/2*h*17) + 17*19 = 17(sqrt(1155) + 19)

Answer:

$2594.07

Step-by-step explanation:

Principal P = $2250
Interest rate r = 2.4% = 0.024 PA compounded
Compound number n = 1 (once per year)
Time t = 6 years

<u>Future amount formula:</u>

F = P(1 + r/n)^(nt)

<u>Substitute given values:</u>

F = 2250(1 + 0.024)^6 = 2594.07

Hello,

$f(2)=\pi + 7\\\\
2=f^{-1}\ o\ f(2)=f^{-1} (f(2))=f^{-1}( \pi + 7 })$
