you dont have to answer them all if you dont want to.
1. A farmer can plant a combination of two different crops on 20 acres of land. Seed costs $120 per acre for crop A and $200 per acre for crop B. Government restrictions limit acreage of crop A to 15 acres, but do not limit crop B. Crop A will take 15 hours of labor per acre at a cost of $5.60 per hour, and crop B will require 10 hours of labor per acre at $5.00 per hour. If the expected income from crop A is $600 per acre and from crop B is $520 per acre, how many acres of crop A should be planted in order to maximize profit?
2. A farm supply store carries 50?lb bags of both grain pellets and grain mash for pig feed. It can store 600 bags of pig feed. At least twice as many of its customers prefer the mash to the pellets. The store buys the pellets for $3.75 per bag and sells them for $6.00. It buys the mash for $2.50 per bag and sells it for $4.00. If the store orders no more than $1,400 worth of pig feed, how many bags of mash should the store order to make the most profit?
3. For what value of k will the graph of 2 x + ky = 6 be perpendicular to the graph of 6 x - 4 y = 12?
4. What is the equation for the inverse of y = Cos x + 3?
5. There are 20 rollers under a conveyer belt and each roller has a radius of 15 inches. The rollers turn at a rate of 40 revolutions per minute. What is the linear velocity of the conveyer belt?
6. Determine the least possible value for B to the nearest tenth if A = 20 degree, a = 7, and b = 11 .
7. Find the number of possible negative real zeros for f(x) = x^3 - 4x^2 - 3x - 9.
