Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet
Given:
Initial investment 450
annual simple interest rate of 5%
Simple interest = Principal * interest rate * term
Simple interest = 450 x 0.05 x 14
Simple Interest = 315
Balance after 14 years: 450 + 315 = $765
We can use compounding interest, compounded once a year.
Total balance = Principal * (1 + interest rate / number of compounding)^(# compounding * term)
Total balance = 450 * (1.05)¹⁴
Total balance = 450 * 1.98
Total balance = 891
Based on these scenarios, the formula that will be used is the second formula, compounding interest formula. The balance at the beginning of year 15 is $891.
I used 14 as the number of years because the problem states at the beginning of year 15. This means 15 has not yet begun and interest is not yet earned.
