4) Rachel and Mark are on a roadtrip. Just when they think they can't take being in the
car with each other any longer, they see a billboard advertising
Have your picture taken with the buffalo
at Cory & June's
Hexaflexagon Mega-Warehouse
The sign is 15 feet wide, perpendicular to a straight road, and 20 feet from the road.
Rachel decides to snap a picture of the sign to take back to show everyone in calculus
class. At what point on the road would Rachel have the best view of the billboard as
they drive by? That is, at what point on the road is the angle subtended by the billboard
a maximum? Is the pair tempted to take the 30-mile detour for the photo-op?
5) Tim and Miguel went to a fortune-teller at the state fair who tipped them off that their
next calculus exam would have a problem involving ladders sliding down a wall. Cindy
suggests they should replicate this in real life to gain an advantage on the rest of the
class, so they all decide to bring a long ladder into their dorm. Tim further adds that they
should use as long of a ladder as possible for an optimal experience. Cindy points out
the problem that they must maneuver the ladder through a right-angle turn where the
hallway constricts from 8 feet down to 5 feet wide. What is the longest ladder the trio
can carry horizontally around the corner?

1) To relieve stress from doing homework problems, Julie has taken up gardening. She
has designed her garden plot in the shape of a circular sector with radius R and angle 0.
Based on the amount of vegetables she wants to grow, Julie has determined the garden
should have an area of 30 square feet. She needs to build an electric fence around the
perimeter to keep Joe out of the tomatoes. Find the dimensions R and 0 which will
minimize the length of fence Julie will need to build.
2) Elizabeth is fed up with AJ's jokes and decides to make him wear a dunce cap in
calculus class. She starts out with a paper circle of radius 12 inches and Luke suggests
making the hat as large as possible for optimal humiliation effect. To do this, Elizabeth
cuts out a sector with angle $ and tapes together the resulting edges to form the cone.
Find the magnitude of ø so that the volume of the AJ's dunce cap is maximized.

Horsetooth Reservoir, but soon get into an argument. Dan pushes Mike off of their
"Little Mermaid" floaty 200 feet from shore and paddles off. The icy cold water has
momentarily made Mike forget he is a really good swimmer. Teri is at a point 200 feet
