The mass of the part of a metal rod that lies between its left end and a point x meters to the right is 3x^2 kg. Find the linear
density when is 1 m, Where is the density the highest? The lowest?
1 answer:
Answer:
6 kg/m
Step-by-step explanation:
mass m = 3x^2.
rho ρ= dm/dx =6x
ρ(1) =6 Kg/m
linear density is the derivative of mass (m) with respect to position(x)
that is how fast is the mass changing at that position.

Answer:
3x-5y=-15
Step-by-step explanation:
Set y=ax+b pass (7,-9) (5,6)
=》-9=7a+b
6=5a+b
=》2a=-15
a=-15/2
b=6-5a=6+37.5=43.5
=》y= -15/2(x)+43.5
2y+15x=87
