Answer:
R(x) = -0.05x^2 +80x
Step-by-step explanation:
Given the two points (x, p), the equation for the price associated with a given demand quantity can be written using the 2-point form:
p = (p2 -p1)/(x2 -x1)(x -x1) +p1
p = (40 -50)/(800 -600)(x -600) +50
p = -0.05x +80 . . . . simplify
Then the revenue equation is ...
R(x) = xp
R(x) = -0.05x^2 +80x
G(x) is the same as saying y =
y = (2)⁻¹ When an exponent is negative it is the same as the inverse of it
y = 1/2¹
y = 1/2
--or--
g(2) = 1/2
The supplementary angle of 120° is 60°.
So your answer is 60 degrees.
