Answer:  2

<u>Step-by-step explanation:</u>

f(x) = 2x + 3        g(x) = x² - 1

f(g(x)) = f(x² - 1)

         = 2(x² - 1) + 3

         = 2x² - 2  + 3

         = 2x² + 1

The largest exponent is 2 so the degree is 2.

A graduated cylinder is filled with 36 cm 3 of liquid the liquid is poured into a different cylinder that has a radius of 3cm ,
Mila [183]

The height of the liquid in the new cylinder is about 1.72 cm

Step-by-step explanation:

The formula of the volume of a cylinder is V = πr²h, where

  • r is the radius of the base of the cylinder
  • h is the height of the cylinder

∵ The volume of the liquid = 36 cm³

∵ The liquid is poured into another cylinder with radius 3 cm

∵ The radius of the base = 3 cm

- To find the height of the liquid in the new cylinder equate the rule

   of the volume by 36

∵ V = πr²h

∴ π(3)²h = 36

∴ 9πh = 36

- Divide both sides by 9π

∴ h = 1.273239545

The height of the liquid in the new cylinder is about 1.72 cm

For f(x)=2x+1 and g(x)=x^2-7, find (f/g)(x)
Drupady [299]
The question is asking us to divide the function f(x) by the function g(x).

Knowing this, we can perform the division:
(2x+1)/(x^2-7) = (f/g)(x)
The simplest answer is \frac{2x+1}{ x^{2} - 7}, as there is no way to further simplify the problem. This means that there is a discontinuity where x =  \sqrt{7}, as it is impossible to divide by 0.

How do we solve this equation 3(2x+1)=?
givi [52]
We are going to distribute the 3 to each term in the parenthesis

6x + 3

and since there is nothing else we can do—no like terms

that is the answer

hope this helps.
