Step-by-step explanation:
So the general formula for compound interest is
where t is typically time in years, and n is how many times it's compounded per year. But in this case it's only compounded 1 time per year so the equation is just
. in this case P is the principal amount, r is the interest, and A is the final amount. So the 5% interest rate becomes 0.05 by dividing by 100 to convert it into decimal form and the principle amount of 11,000. This gives you the formula
. This is the answer to the first question where t is the time in years. When it says "Find interest earned" I'm a bit confused, is it giving you x amount of years where you have to calculate the interest earned or does it want a general equation? Because the general equation would be the final amount - the principle amount which calculates the difference. So the equation for interest earned would be
. To calculate the amount of money after 5 years you simply plug in 5 as t. this gives you the equation

Answer:
Option 3 is correct that is 
Step-by-step explanation:
We have general formula for sum of cube which is

Here, we have a=s and b=6
on substituting the values in the formula we will get

After simplification we will get

After rearranging the terms we will get
which exactly matches option 3 in the given options.
Therefore, option 3 is correct that is 
I think the answer is: ACD
Answer:
X + (X+1) +(X+2)
(X+(X+1)) = 3 *(X+2) + 17
2X +1 = 3X + 6 +17
X = -22
So the three integers are -22 -21 and -20
Double-Check *******************
(-22 -21) = 3 * (-20)
-43 = -60 +17
