Answer:
A. -x^2 + 3x -2
Step-by-step explanation:
We have the expression:
(4x^3 - 12x^2 + 8x)/(-4x)
When we are dividing we can change the division into shorter expressions:
-
+
After we change the expression to make the divisions shorter we can start solving each part individually, dividing the numbers and the variables; to divide variables we rest the exponent of the numerator by the exponent of the same variable in the denominator, for example:
if we have
<em>x^n / x^m = x^n-m </em>
<em>or if we change it by numbers it will be:</em>
<em>x^3 / x^2 = x^3-2 = x^1 = x</em>
Now, solving the expression we get:
-x^2 + 3x - 2

Answer: r = 1.69 inches
h = 2.15 inches
Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:
They want the cones to hold the same volume of 9 cubic inches.
If height is 3:
r = 1.69 inches
When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.
If radius is 2:
h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.
Answer:
34
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 6 ], thus
f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162
f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8
average rate of change = =
= 34
