Find all​ x-values where the function is discontinuous.

The function is discontinuous at x=8 because as x approaches 8 from the left, f(x) approaches -1 but as x approaches 8 from the right, f(x) approaches 1 and -1 and 1 are not equal.

<h3>Answer:   7 goes in the blank space</h3>

The range of values for x is 2 < x < 7

========================================

Explanation:

The hinge theorem says that the larger the opposite side is, the larger the angle will be.

AD = 11, DC = 8

Since AD > DC, this means angle ABD > angle DBC.

--------

angle ABD > angle DBC

20 > 4x-8

20+8 > 4x-8+8 ... add 8 to both sides

28 > 4x

4x < 28 ... flip both sides and the inequality sign

4x/4 < 28/4 ... divide both sides by 4

x < 7

--------

At the same time, the angle 4x-8 cannot be 0 or negative.

So we say 4x-8 > 0. Let's solve this for x.

4x-8 > 0

4x-8+8 > 0+8 ... add 8 to both sides

4x > 8

4x/4 > 8/4 ... divide both sides by 4

x > 2

2 < x ... flip both sides and the inequality sign

--------

We have 2 < x and x < 7. Both of these combine to the compound inequality 2 < x < 7

We can pick any value between 2 and 7 as long as we dont pick x = 2 or we dont pick x = 7.

Howie works at a petting zoo. He fed a piglet 1/5 of a bottle of milk then gave 3/4 of what was left to the calf. How much of th
Lapatulllka [165]

Answer:

\frac{3}{5}th part of the bottle will be drunk by the calf.

Step-by-step explanation:

Part of the bottle fed by the piglet = \frac{1}{5}

Milk left in the bottle = 1 - \frac{1}{5}

                                  = \frac{5-1}{5}

                                  = \frac{4}{5}

Milk drunk by the calf = \frac{3}{4}th of the left part

                                     = \frac{3}{4}\times \frac{4}{5}

                                     = \frac{3}{5}th part of the bottle

Therefore, \frac{3}{5}th part of the bottle will be drunk by the calf.
