Answer this question
andreyandreev [35.5K]

Answer:  OPTION B.

Step-by-step explanation:

We have the following functions f(x) and g(x):

f(x)=x^2-2x-8\\\\g(x)=\frac{1}{4}x-1

In order to find for which values of "x" f(x)=g(x), we can check each option given:

<u>OPTION A</u>

Substitute x=-1.75 into the function f(x) and evaluate:

f(-1.75)=(-1.75)^2-2(-1.75)-8=-1.4375

 Substitute x=-1.75 into the function g(x) and evaluate:

g(-1.75)=\frac{1}{4}(-1.75)-1=-1.4375

Substitute x=-1.438 into the function f(x) and evaluate:

f(-1.438)=(-1.438)^2-2(-1.438)-8=-3.0561

Substitute x=-1.438 into the function g(x) and evaluate:

g(-1.438)=\frac{1}{4}(-1.438)-1=-1.3595

This is not the correct option.

<u>OPTION B</u>

We already know that:

f(-1.75)=-1.4375

g(-1.75)=-1.4375

Substitute x=4 into the function f(x) and evaluate:

f(4)=(4)^2-2(4)-8=0

Substitute x=4 into the function g(x) and evaluate:

g(4)=\frac{1}{4}(4)-1=0

<em> This is the correct option.</em>

<u>OPTION C</u>

We already know that:

 f(-1.438)=-3.0561

 g(-1.438)=-1.3595

Therefore, this is not the correct option.

<u>OPTION D</u>

We already know that:

f(4)=0

g(4)=0

Substitute x=0 into the function f(x) and evaluate:

f(0)=(0)^2-2(0)-8=-8

Substitute x=0 into the function g(x) and evaluate:

g(0)=\frac{1}{4}(0)-1=-1

This is not the correct option.

The volume, V, of the right circular cone with radius r.
Paha777 [63]

Answer:

radius^2 = 3 * Volume / (PI * height)

radius^2 = 3 * (142 cc / 3.14159265 * 8.5)

radius^2 = 3 * (142 cc / 26.703537525 )

radius^2 = 15.9529425493

radius = 4.0 cm
