Factor. Look for a GCF first. X^3+2x^2-48x

Mathematics

Answer:

x(x - 6)(x + 8)

Step-by-step explanation:

First, the GCF of these 3 terms is x.

So to separate x from this it now becomes x(x^2 + 2x - 48).

Now to factor the expression inside the parentheses easily I use "a" and "b" to make it easier.

a + b = 2 (from 2x)

a * b = -48 (from third term of expression)

a = -6, b = 8

Substitute "a" and "b" and I get: x(x - 6)(x + 8)

Given f(x)=x2−2x−2, completing the square to solve for the function's zeros yields which of the following? A. (x−1)2=−2 B. (x−2)

LekaFEV [45]

Answer:

(x-1)² = 3

Step-by-step explanation:

Given f(x)=x²−2x−2

Completing x²−2x−2 = 0 to square

x²−2x − 2=0
x²−2x + 1 - 3 =0
(x - 1)² - 3 = 0
(x - 1)² = 3

Correct choice is D

Natasha2012 [34]

Answer:

The quantities used by Manuela were correct

Step-by-step explanation:

The question is

Did Manuela use the right quantities?

Let

x -----> the parts of oil

y ----> the parts of vinegar

we know that

The ratio of the parts of oil by the parts of vinegar of recipe is

Determine the relation used by Manuela

Compare with the recipe

Is true, the quantities are proportional

therefore

The quantities used by Manuela were correct

Jaime makes the following claim.

Sphinxa [80]

Jaime is incorrect, the angle does not depend on the radius of the circles.

<h3>Is Jaime correct?</h3>

Remember that an angle that defines an arc on a circle, does not depend on the radius of the circle.

So, if we have an angle with a measure of π/3 radians in a circle with a radius of 3 inches and an angle with a measure of π/3 radians in a circle with a radius of 6 inches, these two angles are exactly the same thing.

The radius of the circle only has an impact on the length of the arc defined by the angle.

So Jaime is clearly incorrect.

Find the range of the function f(x) = 4x - 7,

ratelena [41]

Answer:

(- 19, - 11, 5, 25)

Step-by-step explanation:

The given function is f(x) = 4x - 7

Now, we have to find the range of the given function for the given domains.

The domains are given as (2 - 5, - 1, 3, 8) i.e. (- 3, - 1, 3, 8).

Therefore, f(- 3) = 4(- 3) - 7 = - 19

f(- 1) = 4(- 1) - 7 = - 11

f(3) = 4(3) - 7 = 5

f(8) = 4(8) - 7 = 25

So, the ranges of the function are (- 19, - 11, 5, 25) (Answer)
