Formula for amount for compound interest:
Amount, A = P(1 + r/100)^n
Where r is rate, P is principal, and n is the number of years.
P = 2000, r = 5, n = t years.
A = 2000( 1 + 5/100)^t
A = 200(1+0.05)^t
A = 2000(1.05)^t
A(t) = 2000(1.05)^t
None in the option look like the answer we have.
Except you didn't type the last option correctly.
The approximate width of Alice's backyard is 22.36 in.
Let l be the length of the rectangle and w be the width.
l = 2w
A = 1000 m2 = l*w
1000 m2 = 2w *w
500 m2 = w^2
√500 m2 = √w^2
w = <span>22.360679775 in or 22.36 in</span>

x = number of hours after 9 am (eg: x = 1 means 1 hr after 9 am, so 10 am)
f(x) = population count x hours after 9 am
f(1) = population count at 10 am (1 hour later)
f(2) = population count at 11 am (2 hrs after 9 am)
f(2) - f(1) represents the difference in population counts from 10 am to 11 am, or put another way, how much the population increased during that time interval.
Answer:
C.
D.
E.
Step-by-step explanation:
Formula for volume of a cuboid 
. where l is the length, w is the width and h is the height.
Using this equation we can answer the question by using the values given.
From the list of answers, we can compare each one to the answer we got and see if they match up.
The answers that match up are:
C. 
- it is exactly like the answer we got.
D. 
- if we simplify the brackets, it is exactly like the answer we got.
E. 
- once again, if we simplify the brackets it is like the answer we got.
None of the other answers are correct as they do not match up with the answer we got.
