Answer:

192.5 ft²

Step-by-step explanation:

Area of the sector

= (360-100)/360 x π(8.35)²

= 158.195 ft²

Area of the triangle

= 1/2 (8.35)(8.35) sin (100)

= 34.3316 ft²

Area of the shaded part

= 158.195 + 34.3316

= 192.5 ft²

A leading bank is coming up with an investment that pays 8 percent interest compounded semiannually. What is the investment's ef

uranmaximum [27]

The effective rate is calculated in the following way:
$r = {(1 + \frac{i}{n} )}^{n} - 1$
where r is the effective annual rate, i the interest rate, and n the number of compounding periods per year (for example, 12 for monthly compounding).
our compounding period is 2 since the bank pays us semiannually(two times per year) and our interest rate is 8%
so lets plug in numbers:
$r = {(1 + \frac{8\%}{2}) }^{2} - 1 \\ r = {(1 + \frac{1}{25}) }^{2} - 1 \\ r = \frac{676}{625} - 1 \\ r = 0.0816 \: or \: 8.16\%$
