Given the cost function C(x) = 0.81x + 60, 420 and the revenue function R(x) = 1.87x, find the break-even point

Viktor [21]

Answer:

x = 57,542.8571

Step-by-step explanation:

C(x) = 0.81x + 60,420

R(x) = 1.87x

At break even point, Cost function and revenue function becomes equal.

-> C(x) = R(x)

-> 0.81x + 60,420 = 1.87x

-> 60420 = 1.87x - 0.82x

-> 60420 = 1.05x

-> x = 60420/1.05

-> x = 57,542.8571

Thus, at break even point x = 57,542.8571

What is the average rate of change of the function f(x)=4(2)^x from x = 0 to x = 2? Enter your answer in the box.

bekas [8.4K]

average rate of change is just the slope from (0,f(0)) to (2,f(2))

basically, average rate of change=slope= $\frac{f(2)-f(0)}{2-0}$

evalaute each

f(2)=4(2)^2=4(4)=16

f(0)=4(2)^0=4(1)=4

so average rate of change= $\frac{16-4}{2-0}=\fracc{12}{2}=6$

average rate of change is 6
