Answer:

f=  x^2+4x−12 /x

Step-by-step explanation:

Step 1: Divide both sides by x.

fx /x  =  x^2+4x−12 /x

f=  x^2+4x−12 /x

Find the value of x and then the measure of Arc XYZ and Arc XZ. Show work on a piece of paper.
Westkost [7]

<u>Given</u>:

The measure of arc XY is (31x)°

The measure of arc YZ is (35x - 16)°

We need to determine the value of x, measure of arc XYZ and arc XZ.

<u>Value of x:</u>

From the figure, it is obvious that the arcs XY and YZ are congruent.

Thus, we have;

31x=35x-16

Subtracting both sides by 35x, we have;

-4x=-16

   x=4

Thus, the value of x is 4.

<u>Measure of arc XYZ:</u>

The measure of arc XYZ is given by

m \widehat{XYZ}=m \widehat{XY}+m \widehat{YZ}

The measure of arc XY is given by

m \widehat{X Y}=31(4)=124^{\circ}

The measure of arc YZ is given by

m \widehat{Y Z}=35(4)-16=124^{\circ}

Hence, the measure of arc XYZ is given by

m \widehat{XYZ}=124^{\circ}+124^{\circ}=248^{\circ}

Therefore, the measure of arc XYZ is 248°

<u>Measure of arc XZ:</u>

The measure of arc XZ is given by

m \widehat{XZ}=360^{\circ}-m \widehat{XYZ}

Substituting the values, we have;

m \widehat{XZ}=360^{\circ}-248^{\circ}

m \widehat{XZ}=112^{\circ}

Thus, the measure of arc XZ is 112°

The manufacturing cost of an air-condioning unit is $544, and the full-replacement extended warranty costs $113. If the manufact
Paraphin [41]
The manufacturer sells 506,970 units or air-conditioning. The number of units to  be replaced is 20% of that. So,
506970 (0.20) = 101394 units are to be replaced
Since full-replacement extended warrant costs $113 per unit, we have:
101394 ($113) =  $11,457,522

The answer is
<span>b. $11,457,522</span>
