The following account balances are taken from the records of Martin Corp. for the past two years.

$$\begin{aligned} &\begin{array}{lrr} &\text { December } 31\\ &{\mathbf{2 0 1 7}} & {\mathbf{2 0 1 6}} \\ \hline \text { Plant and equipment } & \$ 750,000 & \$ 500,000 \\ \text { Accumulated depreciation } & 160,000 & 200,000 \\ \text { Patents } & 92,000 & 80,000 \\ \text { Retained earnings } & 825,000 & 675,000 \end{array} \end{aligned}$$

Other information available for 2017 is as follows: a. Net income for the year was $200,000. b. Depreciation expense on plant and equipment was$50,000. c. Plant and equipment with an original cost of $150,000 were sold for$64,000. (You will need to determine the book value of the assets sold.) d. Amortization expense on patents was $8,000. e. Both new plant and equipment and patents were purchased for cash during the year.

Required Indicate, with amounts, how all items related to these long-term assets would be reported in the 2017 statement of cash flows, including any adjustments in the Operating Activities section of the statement. Assume that Martin uses the indirect method.

On January 1, Tritrua Auto Company built a new manufacturing facility at a total cost of $15,000,000, and paid cash. To dismantle the plant and restore the property at the end of the plant's 25-year life, the estimated cost (in today's market) is$850,000. Tritrua will depreciate the asset over its useful life using the straight-line method. The asset has no residual value. Tritrua's cost of capital is 6%.

a. Prepare the journal entries required to record the acquisition of the plant asset.

Presume that the assumptions for regression inferences are mel.

Following are the data on plant weight and quantity of volatile emissions.

$$\begin{array}{r|rrrrrrrrrrr} \hline x & 57 & 85 & 57 & 65 & 52 & 67 & 62 & 80 & 77 & 53 & 68 \\ \hline y & 8.0 & 22.0 & 10.5 & 22.5 & 12.0 & 11.5 & 7.5 & 13.0 & 16.5 & 21.0 & 12.0 \\ \hline \end{array}$$

a. Obtain a point estimate for the mean quantity of volatile emissions of all (Solanum tuberosum) plants that weigh 60 g.

b. Find a 95 percent confidence interval for the mean quantity of volatile emissions of all plants that weigh 60 g.

c. Find the predicted quantity of volatile emissions for a plant that. weigh 60 g.

d. Determine a 95 percent prediction interval for the quantity of volatile emissions for a plant that weighs 60 g.

All of the nutritional energy contained in fruits and vegetables is supplied by solar photons through photosynthesis reactions. Estimate the total leaf area on an average tomato plant.

The Wolffia plant is the world's smallest flowering plant. The growth rate for Wolffia microscopica can be calculated from its doubling time of 30 hours $=1.25$ days. Source: Wayne's Word.

(a) Suppose the number of Wolffia at time $t=0$ is $y_0$. Write a function in the form $y=y_0 e^{k t}$, giving the number after $t$ hours.

(b) Write the function from part (a) in the form $y=y_0 2^{f(t)}$.

(c) The article cited above said that one minute plant could theoretically give rise to one nonillion plants or $1 \times 10^{30}$ (one followed by 30 zeros) in about four months. Verify this fact.

A company operates two plants which manufacture the same item and whose total cost functions are

$$C_1=8.5+0.03 q_1^2 \text { and } C_2=5.2+0.04 q_2^2$$

where $q_1$ and $q_2$ are the quantities produced by each plant. The company is a monopoly. The total quantity demanded, $q=q_1+q_2$, is related to the price, $p$, by

$$p=60-0.04 q$$

How much should each plant produce in order to maximize the company's profit? ${ }^{10}$

Given: If Dante gets a part-time job, he can afford a car payment. Dante can afford a car payment.

Conclusion: Dante got a part-time job.

Visit the following EPA Office of Pesticides webpage that provides information on the state of the U.S. federal scientific debate on atrazine: http:// www.epa.gov/oppsrrd1/reregistration/atrazine/ atrazine/update.htm

Write a one-page memo from the perspective of the strategy team at Syngenta, one of the main global manufacturers of atrazine, giving a summary of the EPA activities, findings, and rulings. From a strategy perspective, what overall recommendations would you give, knowing what you do about how the EPA is considering atrazine?

You discover a green, filamentous multicellular eukaryote growing at the edge of a pond. How could you determine if the organism is a green alga or a plant?

Suppose a modern power plant has a $1.00$-GW electric power output at $500 \mathrm{~V}$. It is stepped up to a transmission voltage of $750 \mathrm{kV}$ in a series of five identical transformers. (a) What is the output current at the plant? (b) What is the turn ratio in each of the transformers? (c) What is the current in the high voltage delivery lines?

All of the nutritional energy contained in fruits and vegetables is supplied by solar photons through photosynthesis reactions. If an average tomato plant has ten tomatoes, and if half of the photon energy enters the fruit while the rest is used to grow roots and maintain plant cells, then how many photons supply energy to each tomato each second?
