A = P (1 + r)^n where P = initial amount, r = interest rate , n = number of years and A = amount after n years.
So here we have A = 1393(1 + 0.09) ^ 2 ( 0.09 = 9%)
= $1655.02 (answer)

Answer:
The length of he hypotenuse of the triangle is x = 65.
Step-by-step explanation:
Here, the base of the right triangle = 56
The perpendicular = 33
The hypotenuse of the triangle = x
Now, by PYTHAGORAS THEOREM: In a right angled triangle

or, here

or, 
Hence, the length of he hypotenuse of the triangle is 65.
