Answer:
R = 5% per year
Step-by-step explanation:
Solving for rate r as a decimal
r = n[(A/P)^1/nt - 1]
r = 4 × [(4,835.71/3,092.00)^1/(4)(9) - 1]
r = 0.05
Then convert r to R as a percentage
R = r * 100
R = 0.05 * 100
R = 5%/year
Summary:
The interest rate required to get a total amount of $4,835.71 from compound interest on a principal of $3,092.00 compounded 4 times per year over 9 years is 5% per year.
10 is not a perfect square I believe
15ft because 12x.25=3 so 3ft is 25% of the 12ft, add the 3+12=15
Two negatives make a positive. So, -(-3.7) = 3.7.
The correct answer it C.
Hope this helps,
