Question 1167012: The electric current I (in amperes) passing through a resistor is related to a voltage V across a resistor (in volts) and the resistance R (in ohms) by the formula I=V/R. The resistor is connected across the terminals of a car battery (12 volts). Construct a table of values from 2000 ohms to 5000 ohms. Use intervals of 1000 ohms

Question 1167022: im sory didnt realize i didnt include the actual function here it is.
For a certain company, the cost function for producing x items is C(x)=30x+250 and the revenue function for selling x items is R(x)=−0.5(x−110)2+6,050. The maximum capacity of the company is 140 items.
The profit function P(x) is the revenue function R(x) (how much it takes in) minus the cost function C(x) (how much it spends). In economic models, one typically assumes that a company wants to maximize its profit, or at least make a profit!
Answers to some of the questions are given below so that you can check your work.
Assuming that the company sells all that it produces, what is the profit function?
P(x)=
Hint: Profit = Revenue - Cost as we examined in Discussion 3.
What is the domain of P(x)?
Hint: Does calculating P(x) make sense when x=−10 or x=1,000?
The company can choose to produce either 80 or 90 items. What is their profit for each case, and which level of production should they choose?
Profit when producing 80 items =
Profit when producing 90 items =
Can you explain, from our model, why the company makes less profit when producing 10 more units?
