Answer:
It doesn't have a solution because if you try to graph each line y=5x+10 and y=5x-8, you will have a parallel line
Step-by-step explanation:
Hello,
if x≠-3
f(-3)=-2(-3)^3+(-3)²+16(-3)-15=-2*(-27)+9-48-15=54+9-48-15=0
f(x)/g(x)=(-2x^3+x²+16x-15)/(x+3)=(x+3)*(-2x²+7x-5)/(x+3)= -2x²+7x-5

Answer:
2,400 foot-pounds
Step-by-step explanation:
Say at any instant x is length of Rope
Work done in lifting rope by dx amount will be:
dw = -(2.5x + 10)dx
w = -(40)∫(2.5x+10)dx
w = (2.5(40)^2) / 2 + 10(40)
w = 2000 + 400
w = 2,400 foot-pounds
