determine the price and quantity for which revenue is maximised given a firm demand function of a particular commodity to be (12
DerKrebs [107]
Demand
D(q)=(12-q)^(1/2)
Revenue,
R(q)=q*D(q)=q*sqrt(12-q)
At maximum revenue, 
R'(q)=0
where
R'(q)=sqrt(12-q)-q/[2(sqrt(12-q))]=0
Solve for q=8.
Hence, quantity=8, price=sqrt(12-q)=sqrt(12-8)=sqrt(4)=2

Find the distance between endpoints that are located at (-4, 4) &amp; (-1, 0)
joja [24]

Answer:

<h3>The answer is 5 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4, 4) & (-1, 0)

The distance between them is

d =  \sqrt{ ({ - 4 + 1})^{2} +  ({4 - 0})^{2}  }  \\  =  \sqrt{  ({ - 3})^{2}  +  {4}^{2} }  \\  =  \sqrt{9 + 16}  \\  =  \sqrt{25}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 5 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>5 units</h3>

Hope this helps you
