Mr. Lopez picks up 2 pallets of dog food to deliver to the animal shelter. Each pallet contains 40 bags of dog food, and the dog food weighs \(37 \frac{1}{2}\) pounds per bag. What is the total weight, in tons, of the dog food Mr. Lopez delivers to the animal shelter?
A \(1 \frac{1}{2}\) T
B 2 T
C \(2 \frac{1}{2}\) T
D \(\frac{3}{4}\) T

Multiply the number of bags by the weight per bag: \(\displaystyle{40}\cdot{37}{\left(\frac{{1}}{{2}}\right)}={40}\cdot{\left(\frac{{75}}{{2}}\right)}={20}{\left({75}\right)}={1500}\) pounds
There are 2 pallets so the total weight is: \(\displaystyle{1500}×{2}={3000}\) pounds
1 ton = 2000 pounds, so we have: 3000 pounds \(\times(\frac{1 ton}{2000 pounds})=\)\(\displaystyle\frac{{3}}{{2}}={1}{\left(\frac{{1}}{{2}}\right)}\) tons
So, the answer is choice A.

Determine whether each statement makes sense or does not make sense, and explain your reasoning. I’m using a photocopier to reduce an image over and over by 50%,so the exponential function \(\displaystyle{f{{\left({x}\right)}}}={\left(\frac{{1}}{{2}}\right)}^{{x}}\) models the new image size, where x is the number of reductions.

You open a bank account to save for college and deposit $400 in the account. Each year, the balance in your account will increase 5%. a. Write a function that models your annual balance. b. What will be the total amount in your account after 7 yr? Recall that the general form of an exponential function is \(\displaystyle{f{{\left({x}\right)}}}={a}{b}^{{x}}\).
Given the situation described, what is a? What is b? Write the function that models your annual balance. Check to make sure the function you created provides the same values you put into your table for years 1, 2 and 3. a = _____ b = _____ f(x) = _____

For the following exercises, consider this scenario: For each year t, the population of a forest of trees is represented by the function \(A(t)=115(1.025)^t\). In a neighboring forest, the population of the same type of tree is represented by the function \(\displaystyle{B}{\left({t}\right)}={82}{\left({1.029}\right)}^{{t}}\). (Round answers to the nearest whole number.) Discuss the above results from the previous four exercises. Assuming the population growth models continue to represent the growth of the forests, which forest will have the greater number of trees in the long run? Why? What are some factors that might influence the long-term validity of the exponential growth model?

For the following exercises, use a graphing utility to create a scatter diagram of the data given in the table. Observe the shape of the scatter diagram to determine whether the data is best described by an exponential, logarithmic, or logistic model. Then use the appropriate regression feature to find an equation that models the data. When necessary, round values to five decimal places.
\(\begin{array}{|c|c|c|c|c|c|c|c|c|} \hline x & 0 & 0.5 & 1 & 1.5 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\ \hline f(x) & 2.2 & 2.9 & 3.9 & 4.8 & 6.4 & 9.3 & 12.3 & 15 & 16.2 & 17.3 & 17.9 \\ \hline \end{array}\)
