Answer:
A) 32 kg/m
B) 48 kg/m
C) 72 kg/m
Step-by-step explanation:
We are given mass is; m = 4x²
Linear density is the derivative of mass with respect to the position x. So linear density is;
ρ = dm/dx
Differentiating 4x²,we have; ρ = 8x
A)at x = 4; ρ = 8(4) = 32 kg/m
B) at x = 6; ρ = 8(6) = 48 kg/m
C) at x = 9; ρ = 8(9) = 72 kg/m

Correct choice is B
Answer:
The one showing only the point (10, 3)
Or the linear plot with the point +10 highlighted.
Step-by-step explanation:
Option m = 17
y = total cost of the service
m = number of miles run
y = 1.25 + 0.75 m
Equal the cost to the amount available by Henri
14 = 1.25 + 0.75m
Solve for m
m = (14 - 1.25)/0.75 = 12.75 / 0.75 = 17 miles.
