Question 168547: I have a couple of homework problems that I am having trouble with. Any help you can give me to understand how to work these problems would be appreciated.
The Cotes have 30 feet of picket fence with which to enclose a flower garden. What dimensions should the garden have in order to maximaze area? I believe the equation I would use is A(w) = (30-2)w.
Find the value of "a" such that f(x)=ax2+16x+38 has a minimum value of 6. Would this answer be 96/19?
