Question

4. You are building a new walking track in Providence, above the city. The company that hired your team gave you a basic idea of the track shape they were interested in, but told your team to just ensure the area was maximized to give walkers a great view of the city: x

a. Find a formula for the area enclosed by the track, using x and y as your only variables (as pictured). Simplify your answer as much as possible. (Hint: you may want to break the track into a few shapes to find the area).

b. Find a formula for the perimeter of the track. Simplify your answer as much as possible.

c. Find the dimensions of both x and y that maximize the area (I suggest trying to find your y value first and do not round your answers until the very end), given that the total perimeter of the track is 950 meters. You must use optimization methodology to solve this problem and you must show that this is a maximum. (Round your answer to 5 decimal places, if necessary).

d. Determine the maximum area. (Round your answer to 3 decimal places, if necessary).

e. Explain the contextual meaning of your answer to part (c).

1. A city with 4% unemployment and no inflation is considering
building a new stadium for its professional football team. The team
currently plays in an old stadium owned by the city. If a new
stadium were to be built, it would cost city $400M (M for million)
to demolish the old one and build the new one. The new stadium
would be expected to last for 40 years and the city would finance
the costs of the project by...

Imagine that you are moving to a new city after you graduate to
start a job. You are deciding how much of your paycheck to use for
housing (call this H) and how much to save for other spending (call
this S). Your utility function is U ( H , S ) = H 0.5 ⋅ S. Housing
is measured in square feet, and the cost per square foot is p h.
Saving is measured in terms of dollars and...

The Chamber of Commerce in a Canadian city has conducted an
evaluation of 300 restaurants in its metropolitan area. Each
restaurant received a rating on a 3-point scale on typical meal
price (1 least expensive to 3 most expensive) and quality (1 lowest
quality to 3 greatest quality). A crosstabulation of the rating
data is shown below. Forty-two of the restaurants received a rating
of 1 on quality and 1 on meal price, 39 of the restaurants received
a rating...

In this exercise, you will analyze the supply-demand equilibrium
of a city under some special simplifying assumptions about land
use. The assumptions are: (i) all dwellings must contain exactly
1,500 square feet of floor space, regardless of location, and (ii)
apartment complexes must contain exactly 15,000 square feet of
floor space per square block of land area. These land-use
restrictions, which are imposed by a zoning authority, mean that
dwelling sizes and building heights do not vary with distance to...

1.
The total world population is forecast to be
P(t) = 0.00073t3 − 0.072t2 + 0.9t +
6.04 (0 ≤ t ≤ 10)
in year t, where t is measured in decades,
with t = 0 corresponding to 2000 and
P(t) is measured in billions.
a. World population is forecast to peak in what year?
Hint: Use the quadratic formula. (Remember that
t is in decades and not in years. Round your answer down
to the nearest year.)
