4. determine the amount of a $3000 investment at 9%/a compounded monthly for 6 years. [4 marks]

A = $ 5137.65 .

Step-by-step explanation:

Amount = $3000

interest rate = 9 %

                    = 9/12 = 0.75%  

compounded monthly for

time = 6 years.

       = 6 × 12 = 72 months.

A = $ 5137.65

hence, the amount after compounding $3000 at the rate of 9% after 6 years is  A = $ 5137.65 .

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
