Answer:
a) 13913
b) 4913.82
Step-by-step explanation:
The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
In this question:
Investment of 9000, so 
Interest rate of 8%, so 
Compounded quarterly, so 
5 years and 6 months, that is, 5 years and half, so 
(a) How much would the value of her savings at the end of the term?


(b) How much is the interest earned by your savings?
The amount subtracted by the principal. So
13913.82 - 9000 = 4913.82
Hey! Sorry if my answer comes late, I'm going to try and explain the problem to you.
So first you subtract 12 from 36, getting 24.
Now, you have to figure out what m is since 3/4 of it is 24. What is 24 3/4 of?
32.
So, the answer is m = 32
The correct answer 32.5 :)
Answer:

Step-by-step explanation:
Use this to remember the trigonometry ratios:
SOH-CAH-TOA
Because:
Sine=Opposite/Hypotenuse → SOH
Cosine=Adjacent/Hypotenuse → CAH
Tangent=Opposite/Adjacent → TOA
Use the inverse of the tangent ratio since you need to find the angle measure.

Answer:
F=7xy²
Step-by-step explanation:
Rewrite the question
4xy * F = 28x^2y^3 Divide by 4xy

Divide the 4 into the 28.
Divide the x into the x^2
Divide the y into the y^3



F = 7xy²
