Answer:
B
Step-by-step explanation:
We are given:
We are going to put 4x in place of the second y since the first y equaled it:
So we can factored this equation:
This implies 2x=0 or x-2=0.
2x=0
Divide both sides by 2:
x=0
x-2=0
Add 2 on both sides:
x=2
If x=0 and y=4x, then y=4(0)=0 so we have (0,0) is an intersection.
If x=2 and y=4x, then y=4(2)=8 so we have (2,8) is an intersection.
Answer:
a) T(r) = r.D(r)
b) 975 people per square mile.
Step-by-step explanation:
(a)
The units of D(r) are
when multiplying the density by the area we get the amount of people in that area, so
(b)
The average rate of change of T(r) over the interval [5,7] is
but D(7) = 350 and D(5) = 100, so
and the average rate of change of T(r) over the interval [5,7] is 975 people per square mile.
