Step-by-step explanation:
It's like addition, when you multiply exponents that are on the same bases as each other.
Answer with Step-by-step explanation:
We are given
Volume of blood=V=7500 L=
1 liter=
Height of person=h=1.5 m
Density of blood,
We have to find the work done and power of person's heart.
We know that
Work done,
Where 
Using the formula

Time,t=1 day=
Power, P=
Using the formula

Given :
Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile.
In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. y = $0.17x + $15.89 .....1)
To Find :
How much did Hans pay for his trip.
Solution :
x = 450 miles.
Putting value of x in equation 1 we get :
y = $(0.17×450 + 15.89)
y = $(76.5+15.89)
y = $92.39
Therefore, Hans will pay $92.39 for his trip.
Hence, this is the required solution.
