Answer:
1/3 of 3 hours should be 20 minutes
The answer is 21 m squared
3(5)=15
3(2)=6
15+6=21
The formula for the amount A in an account with principal P and interest rate r compounded annually for t years is
... A(t) = P(1+r)^t
You want to find A when P=400, r=0.05, and t=3. Substituting those values gives you
... A(3) = 400·(1 +0.05)³
The appropriate choice is
... A. A(3) = 400·(1 +0.05)³
Answer:

Step-by-step explanation:
We find slope by; change in y ÷ change in x,
Change in y = -4 - 3 = -7
Change in x = 7 - - 2 = 9
Slope of line MN = -7 ÷ 9 =
