Answer:
1st solution is -2x+12
2nd solution is 5x+31
3rd one doesnt have a solution
Step-by-step explanation:
Answer:
no, because it has a constant rate of change
Step-by-step explanation:
this is because the x and y change at the same rate. non linear means that they dont change at the same rate.
The tree trunk is a cylinder so we apply that formula:
It is VCylinder = density x pi x radius x height
So the given in our problem is:
Density = 45 lb/ft^3 = 720.8 kg / m³
Radius = 3ft
Height = 10 ft
Insert variables that in our equation:
VCylinder = 720.8 kg / m³ * pi * 3ft² * 10 ft = 5771.26 kgs
