Graph the following equations; calculate the slope, x-intercept, and y-intercept, and label the intercepts on the graph.
1. A temperature of 41 degrees F is equivalent to 278.2 degrees K, while a temperature of 86 degrees F is equivalent to 303.2 degrees K. Find the equation converting Kelvin temperature to Fahrenheit. What is the Fahrenheit temperature when it is 180 degrees K?
2. A semiconductor manufacturer seeks to maximize its profits. Testing indicates that they can produce 100,000 chips per week at a cost of $40 per chip, and sell them for $65 per chip. They also find that they can produce 125,000 chips per week at a cost of $35 per chip, and sell them for $63 per chip. How much profit can they expect to earn if they produce 130,000 chips per week?
Please note that we don't do students' homework for them. Our tutors try to give you the information to help you complete your assignment on your own. If there's not a tutor with this specialty online right now, be sure to go back into your textbook.
Once YOU have come up with attempted answers to YOUR questions, please re-post and let us know what you think. Then someone here will be happy to critique your work.
I am doing research on math homework help sites and I was wondering if you have accomodations for non-english speaking students or ELL students
