L=$45, P=$600, t=2 years What is the annual interest rate?

The interest rate required to  accumulate simple interest of $ 45.00  from a principal of $600.00  over 2 years is 3.75% per year.

Step-by-step explanation:

Given

l = $45

P = $600

t = 2 years

To determine

What is the annual interest rate = r = ?

Using the Simple Interest Formula

I = Prt

r = I/Pt

substituting l = 45, P = 600 and t = 2 years

r = 45 / ( 600 × 2 )

  = 0.0375

converting r decimal to a percentage = 0.0375 * 100 = 3.75% per year

Thus, the interest rate required to  accumulate simple interest of $ 45.00  from a principal of $600.00  over 2 years is 3.75% per year.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
