Find the derivative of F(x)=-x^4+4x^3+ 70 for 0<=x<=3

timofeeve [1]

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].

Anybody have an answer?

Usimov [2.4K]

You can cross out sin x from both the numerator and denominator, as sin x over sin x should always equal 1.

The answer is -cos x.

Find the diameter of the base of a right cylinder if the surface area is 128(pi) and the height is 12cm.

Gelneren [198K]

$d=2r\\
A=128 \pi \\
A=2 \pi r^{2} +2 \pi rh \\\\
2 \pi r^{2} +2 \pi rh = 128 \pi \\
2 r^{2} +2rh = 128\\
2 r^{2}+24r-128=0\\
r^{2}+12r-64=0\\
delta=400\\
r_{1/2} = -16/4 \\
r=4cm\\
d=8cm\\
$

Radius / diameter as a length cannot be negative, that's why '-16' is wrong.
