Alika [10]

Answer: B) 86°

Step-by-step explanation:

The angles of a triangle always add to equal 180.

So let's call the third angle x and add the other two angles with it.

32+62+x=180

94+x=180

Now we solve for x

Subtract 94 from both sides

94-94+x=180=94

x=86

A company knows that unit cost C and unit revenue R from the production and sale of x units are related by Upper C equals StartF

levacccp [35]

Answer:

$990 per unit.

Step-by-step explanation:

The Unit Cost (C) and Unit Revenue R from the production and sale of x units are related by the function:

$C=\dfrac{R^2}{220000} +3221$

We are required to find the rate of change of revenue per unit when the cost per unit is changing by $9 and the revenue is $1,000.

Rate of Change of C,

$\dfrac{dC}{dt}=\dfrac{R}{110000} \dfrac{dR}{dt} \\\dfrac{dC}{dt}=\$9, R=\$1000\\9=\dfrac{1000}{110000} \dfrac{dR}{dt}\\\dfrac{dR}{dt}=9 \div \dfrac{1000}{110000}\\=9 X \dfrac{110000}{1000}\\\dfrac{dR}{dt}=\$990 $ per unit$$

The Revenue is changing at a rate of $990 per unit.
