Answer:

the idea is to devide the shape into 3 smaller parts.

Step-by-step explanation:

devide it to three areas :

> semi-circle (0.5 * pi * R), R=5

>Square (10 * 10)

> triangle (0.5 * base * height),

bsse =10, height =7

Add them together.

What annual rate of interest is required to triple an investment in 7 years if it were compounded quarterly?

Jobisdone [24]

Answer:

Option C) 16.01%

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=7\ years\\P=\$x\\A=\$3x\\n=4$

substitute in the formula above

$3x=x(1+\frac{r}{4})^{4*7}$

$3=(1+\frac{r}{4})^{28}$

Apply log both sides

elevated both sides to 1/28

$\sqrt[28]{3}=(1+\frac{r}{4})$

Multiply by 4 both sides to remove fraction

$4\sqrt[28]{3}=4+r$

subtract 4 both sides

$r=4\sqrt[28]{3}-4$

$r=0.1601$

convert to percentage

$r=0.1601*100=16.01\%$
