Lets suppose k is the constant of proportionality.
z = k * x / y
when x is 16 and y is 17, z has the value 11.294117647059
11.294117647059 = k * 16/17
Multiplying 17 on both sides
11.294117647059 * 17 = k * 16
192 = k * 16
Dividing 16 on both sides
192/16 = k
k = 12
Now when x= 22, and y= 26
z = k * x/y
z = 12 * 22 / 26
z = 10.1538461538 : Answer
Hope it will help :)
732.4 because just put in a decimal before a # and then do place value to a whole #.
Answer:
a. 
b. 
c.


Step-by-step explanation:
a) The marginal cost function is given by the derivative of the total cost function, in this way the marginal cost function for this company is:

b) The income function is given by the relation
.
The marginal revenue function for the company is given by the derivative of the revenue function, in this way the marginal revenue function is:

(c) The profit function of the company is given by the relation
, and the marginal utility function is given by the derivative of the utility function, in this way , the marginal utility function is:

When q = 2000, the marginal utility is:

When q = 7000, the marginal utility is:

Answer:
11, A
Step-by-step explanation:
90 - 35 = 55
55/5 = 11
