Answer:
b = 11 m
l = 44 m
Step-by-step explanation:
l = 4b (length is four times width)
Perimeter = 110 m
2 * ( l + b ) = 110
2 * (4b + b ) = 110
2 * 5b = 110
b = 110 / ( 2*5) = 11
b = 11 m
l = 4b = 4 * 11 = 44 m
64 because if she asked some students she didn’t ask her class
Given the rate of water flow is given by:
r(t)=85e^(-0.04t)
thus the amount of water flow in the first hour when t=1, will be:
r(1)=85e^(-0.04*1)
=81.667
thus the amount of water that flowed out will be:
85-81.667
=3.333 liters
Answer:
Step-by-step explanation:
We have been given a indefinite integral 
. We are asked to find the indefinite integral.
We will use partial fraction formula to solve our given problem.
Using difference rule of integrals, we will get:
Now, we need to use u-substitution as:
Let 
.
Substitute back these values:
Let us add a constant C.
Therefore, our required integral would be .
