Mathematics

Answer:

Step-by-step explanation:

The area of a sector has the formula

A_s=\frac{\theta}{360}*\pi r^2 Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:

A_s=\frac{75}{360}*(3.14)(4)^2 and simplifying that a bit to look less threatening, but not by much:

A_s=\frac{5}{24}(3.14)(16) and

A_s=\frac{251.2}{24}=\frac{157}{15}=10.466666666... Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.

How much would $200 invested at 5% interest compounded monthly be worth after 9years? Round your answer to the nearest cent
Feliz [49]

Answer:

$311.20

Step-by-step explanation:

Here we are required to use the Compound interest formula for finding the Amount at the end of 9th year

The formula is given as

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

Where ,

A is the final amount

P is the initial amount = $200

r is the rate of interest = 5% annual = 0.05

n is the frequency of compounding in a year ( Here it is compounding monthly) = 12

t is the time period = 9

Now we substitute all these values in the formula and solve for A

A=200(1+\frac{0.05}{12})^{9\times 12}

A=200(1+0.00416)^{108}

A=200(1.00416)^{108}

A=200 \times 1.556

A=311.20

Hence the amount after 9 years will be $311.20
