A farmer wants to fence an area of 24 million square feet in a rectangular field and then divide it in half with a fence parallel to one of the sides of the rectangle. Let y represent the length (in feet) of a side perpendicular to the dividing fence, and let x represent the length (in feet) of a side parallel to the dividing fence. Let F represent the length of fencing in feet. Write an equation that represents F in terms of the variable x. F(x) = Find the derivative F'(x). F'(x) = Find the critical numbers of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) X = What should the lengths of the sides of the rectangular field be (in ft) in order to minimize the cost of the fence? smaller value ft larger value ft Submit Answer
A rectangular parcel of land has width, w feet. The length of the diagonal, d, between opposite corners is 18 feet more than the length of the parcel. Note that d is lowercase. (a) Express the length, L, of the parcel as a function of d. (b) Express the width, w, of the parcel as a function of d. (c) Express the area, A, of the parcel as a function of d. L = W = A = (d) Suppose a fence is to be built around the perimeter of the rectangular parcel of land. The fencing material will cost $25 per foot. Express the total cost, C, of fencing the parcel as a function of d. C =

2. The new cookbook you just got gives all the oven temperatures in degrees Celsius but your oven uses degrees Fahrenheit. Additionally, your oven runs hot and you always have to decrease the prescribed temperature by 15° F. Write an expression using a composition of functions that will determine how high you have to preheat your oven when a recipe from your new cookbook calls for a temperature of t° F. (Hint: C-(F-32) and F=C+32 are the equations to convert between degrees Celsius C and degrees Fahrenheit, F.)
The total yield of corn on Mr. Geller's farm from 1991 to 2010 can be modeled by the function f(x) =2x3+154x2+292x-600 (measured in kilograms) and the area of Mr. Geller's farm from 1991 to 2010 can be modeled by g(x) = 2x + 150(measured in hectares), where x is the number of years since1991. Which of the following expressions correctly describes the average yield of corn per hectare?

Jeff delivers pizza for Papa Jim’s Pizza. Papa Jim’s pays Jeff $6.75 per hour. In addition to this hourly rate, Jeff earns $0.65 for every pizza he delivers. Write the function that describes Jeff’s wages, where x represents the number of pizzas he delivers during a 8-hour shift. If Jeff works a 8-hour shift and delivers 67 pizzas during his shift, how much money will he earn?
The volume, V, of a sphere in terms of its radius, r, is given by V (r) = 7³. Express r as a function of V, and find the radius of a sphere with volume of 200 cubic feet. Round your answer for the radius to two decimal places. Enclose numerators and denominators in parentheses. For example, (a - b)/(1+n). Include a multiplication sign between symbols. For example, a * . r (V) = 640
