I need help finding R

1 answer:

5 0

I think it'd be (-18,-9) because the change from Q to Q' was by 9 so I would assume that to get R' you would also multiply the x,y by 9

seond would be twice of previous one so
1+2+4+8+16+32+64+138=265 inches

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

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.

You have 72 grams of a radioactive kind of barium. If its half-life is 11 minutes, how much will be left after 22 minutes?

lara [203]

None because half is 36 which is 11 minutes so 22 minutes would mean nothing is left
