You just bought a new car for $22,000. Assume that the value of your new car depreciates at a constant \(12\ \%\) per year.

1) The decay rate is square

2) The decay factor is square

3) The equation of the function that represents the value, V(t), of the car in dollars t years from now is \(V\ =\ \Box\) (Write an expression that completes the function's equation.)

Answers (1)


Step 1 Given that the value of the car depreciates at a constant \(12\ \%\) per year.

That means the decay \(rate = r = 12\ \% = 0.12\) The decay factor is\(b = 1\ −\ r = 1\ −\ 0.12 = 0.88\)

Step 2 Given that the initial value is $22000 That means \(a = 22000\)

And the decay factor\(= b = 0.88\) So the equation of the function is: \(V(t) = a(b)^{t}\)
\(V(t) = 22000(0.88)^{t}\)

Answer(1): \(0.12\)

Answer(2): \(0.88\)

Answer(3): \(22000(0.88)^{t}\)

The dominant form of drag experienced by vehicles (bikes, cars,planes, etc.) at operating speeds is called form drag. Itincreases quadratically with velocity (essentially because theamount of air you run into increase with v and so does the amount of force you must exert on each small volume of air). Thus
where A is the cross-sectional area of the vehicle and \(\displaystyle{C}_{{d}}\) is called the coefficient of drag.
Part A:
Consider a vehicle moving with constant velocity \(\displaystyle\vec{{{v}}}\). Find the power dissipated by form drag.
Express your answer in terms of \(\displaystyle{C}_{{d}},{A},\) and speed v.
Part B:
A certain car has an engine that provides a maximum power \(\displaystyle{P}_{{0}}\). Suppose that the maximum speed of thee car, \(\displaystyle{v}_{{0}}\), is limited by a drag force proportional to the square of the speed (as in the previous part). The car engine is now modified, so that the new power \(\displaystyle{P}_{{1}}\) is 10 percent greater than the original power (\(\displaystyle{P}_{{1}}={110}\%{P}_{{0}}\)).
Assume the following:
The top speed is limited by air drag.
The magnitude of the force of air drag at these speeds is proportional to the square of the speed.
By what percentage, \(\displaystyle{\frac{{{v}_{{1}}-{v}_{{0}}}}{{{v}_{{0}}}}}\), is the top speed of the car increased?
Express the percent increase in top speed numerically to two significant figures.

The unstable nucleus uranium-236 can be regarded as auniformly charged sphere of charge Q=+92e and radius \(\displaystyle{R}={7.4}\times{10}^{{-{15}}}\) m. In nuclear fission, this can divide into twosmaller nuclei, each of 1/2 the charge and 1/2 the voume of theoriginal uranium-236 nucleus. This is one of the reactionsthat occurred n the nuclear weapon that exploded over Hiroshima, Japan in August 1945.
A. Find the radii of the two "daughter" nuclei of charge+46e.
B. In a simple model for the fission process, immediatelyafter the uranium-236 nucleus has undergone fission the "daughter"nuclei are at rest and just touching. Calculate the kineticenergy that each of the "daughter" nuclei will have when they arevery far apart.

Is there sufficient evidence to conclude that there is a linear correlation between weights of lemon imports from Mexico and U.S. car fatality rates? Do the results suggest that imported lemons cause car fatalities? \(\begin{array}{|c|c|}Lemon\ imports &230&265&368&480&630\\ Crash\ Fatality\ Rate&159&157&15.3&15.4&14.9\end{array}\)

American automobiles produced in 2012 and classified as “large”; had a mean fuel economy of 19.6 miles per gallon with a standard deviation of 3.36 miles per gallon. A particular model on this list was rated at 23 miles per gallon, giving it a z-score of about 1.01. Which statement is true based on this information?

A) Because the standard deviation is small compared to the mean, a Normal model is appropriate and we can say that about \(84.4\%\) of of large automobiles have a fuel economy of 23 miles per gallon or less.
