Area Word Problem + Graph Problem

  1. Jun 14, 2009 #1
    PROBLEM #24- A goat rancher is going to fence off a rectangular pen in the middle of a large open area. Build an equation to help determine the maximum area (to the nearest sq ft) that can be fenced off if 1200 ft of fencing is avilable. Include a diagram as a part of your solution.)

    I have attached the two problems I need help with in picture format for number 24 and 25. I need to write an equation for 24 which I am having trouble with even though I know the answer is 90,000 sq ft
    @ 300ft x 300ft.

    On #25 I am not sure if this is a line, function, or if it even has a slope or pattern. How do I answer the questions beneath? Thanks.






    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Ah, that is bad luck. They still haven't approved the image.

    Ok so for #24 you need to build an equation to help find the maximum area. It says that perimeter is 1200ft. What kind of equations can you think of that would be helpful? How about the equation for perimeter and area? If you find those two equations you are finished.

    For problem 25 you say you are "not sure if this is a line, function, or if it even has a slope or pattern". It is precisely the points shown: (-2, 5), (-1, 3), (1, 0), (3, -3), and (4, -5).

    The "domain" is the set of all "x" values- all first numbers in the pairs.
    The "range" is the set of all "y" values- all second numbers in the pairs.
