Answer:
-4x^3 +12x^2 for 0 < x < 3
Step-by-step explanation:
The power rule is appropriate:
(d/dx)x^n = n·x^(n-1)
This is applied to each of the terms.
F'(x) = -(4·x^3) +4(3x^2) +0
F'(x) = -4x^3 +12x^2 . . . . for 0 < x < 3
__
The derivative is not defined at the endpoints of the interval, so F'(x) is only defined on (0, 3), not [0, 3].
Depending on which variable is needed to be independent the answer could be either:
f(j)=2j+12 or
f(k)=2k+12
First car: $10 + 3 every mile
Second car: $20 + 2 per every mile
For the part that says "Write an equation that represents the cost of
each car service and determine when they cost the same.", find the LCM of 13 and 22.
X=0 is the answe because it has no slope and touches y axis
Answer:
length = 32m, width= 16m
Step-by-step explanation:
l=2w
2(2w+w)=96
2(3w)=96
6w=96,w= 96/6 = 16m
l=2w=2x16=32m
