Answer:
Riley will earn interest of $1706.86 in 15 years. But when the same problem solved for interest compounded annually we get,
c)1663.90
The options does not match with answer
Step-by-step explanation:
Given
principal amount P = $ 1000
rate of interest r = 6.75 % = 6.75/100 =0.0675
time t = 15
compounded semi annually, hence
no. of times interest is compounded, n = 2
We know that the formula for deriving final amount (A) is
A = P
Substituting the known values , we get
A = 1000 x
= $2706.86
Hence the interest earned = A - P
= $2706.86 - $ 1000
= $1706.86
The answer is $1706.86
But when the same problem solved for interest compounded annually we get, n=1 and so
A = 1000 x
= 2663.90
Hence interest earned = $2663.90 - $ 1000
= 1663.90
6. Is B. real numbers
7. B. finding area of square.
8. A
9. A. True
10. False.
Answer:
2 pi*r^2 + 2 * pi *r * h
Step-by-step explanation:
I will assume that you are looking for surface area
We need to find the area of the top and the bottom, which is the area of a circle
top: pi * r^2
Bottom: pi r^2
Then the side which is the circumference times the height ( it is a rectangle)
side: 2 * pi *r * h
Add them together to get the surface area
SA = pi * r^2 + pi * r^2 + 2 * pi *r * h
= 2 pi*r^2 + 2 * pi *r * h
your answer will be 1275 yd^2
Step-by-step explanation:
