Solve the following inequality: x^2-8x + 7> 0

The solution lie in  

Step-by-step explanation:

Given : Inequality

To find : Solve the inequality?

Solution :

First we convert the inequality into equation,

Solving by middle term split,

Use each root to create test intervals,

For x<1, let x=0

True.

For 1<x<7, let x=3

False.

For x>7, let x=8

True.

Therefore, The inequality form is x<1 or x>7.

The interval notation is

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
