Answer:
Step-by-step explanation:
We are given the following in the question:
Quantity, q
Selling price in dollars per yard, p
Total revenue earned =
f(20)=13000
This means that 13000 yards of fabric is sold when the selling price is 20 dollars per yard.
f′(20)=−550
This means that increasing the selling price by 1 dollar per yards there is a decrease in fabric sales by 550.
We have to find R'(20)
Differentiating the above expression, we have,
Putting the values, we get,
= x(8 -8) +(10 +13)
= 0 +23
= 23
Selection D is appropriate.
Answer:
Step-by-step explanation:
for y intercept
we calculate f(0) and the value is y intercept
for the slope we have 2 points (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
your answer would be 19 inches because 24 divided by 12(length of a foot in inches) is 2 and therefore you also divide 4.75 by 2 to get 2.375 and multiply that by 8 the amount of feet and your done
12(2w-3)=6w
Distribute
24w-36=6w
Rearrange
18w=36
Divide both sides by 18
W=36/18
Final answer:
W=2
