Unit price is expressed as
Let x be the number of units of a thousands.
So, Revenue function is given by
.(b) Find the marginal revenue function R'..
Marginal revenue function becomes,
(c) Compute R'(2).
Hence, a) , b)

<span>ΔPQR is a right triangle
∡Q is a right angle. ⇒⇒⇒ ∡Q = 90°
QR measures 33 point 8 ⇒⇒⇒ QR = 33.8 ⇒ leg of the triangle
PR measures 57 point 6 ⇒⇒⇒ PR = 57.6 ⇒ hypotenuse of the triangle
we can find ∡P using sin function
sin P = QR/PR = 33.8/57.6 = 0.5868
∴ ∡P =
