Lamprino Appliance uses a perpetual inventory system. The following are three recent merchandising transactions:
June 10 Purchased 10 televisions from Mitsu Industries on account. Invoice price, $\$ 300$ per unit, for a total of $\$ 3,000$. The terms of purchase were $2 / 10, \mathrm{n} / 30$.
June 15 Sold one of these televisions for $\$ 450$ cash.
June 20 Paid the account payable to Mitsu Industries within the discount period.

Instructions
a. Prepare journal entries to record these transactions assuming that Lamprino records purchases of merchandise at:

1. Net cost
2. Gross invoice price

Find f'(x) and state the domain of f'. f(x) = 1n (x + 2)

State the amplitude of: $y=\sqrt{7} \sin x$

A retail store has various sizes of television sets made by the same manufacturer. The price for a set is a function of the screen size, measured in inches along the diagonal. The prices are listed here.

Make a scatter plot of the data. Based on the scatter plot, explain why a quartic function is a more appropriate mathematical model than a cubic function.

A plastic injection molding process is often used in manufacturing because of its ability to mold complicated shapes. An experiment was conducted on the manufacture of a television remote part, and the warpage (mm) of the part was measured and stored in TV Remote.

Two factors were to be considered, the filling time $(1,\ 2, \text{or}\ 3\ \text{sec})$ and the mold temperature $(60,\ 72.5,\ \text{or}\ 85 \degree \text{C})$.

At the $0.05$ level of significance, (a) is there an interaction between filling time and mold temperature?

Solve. If no solution exists, state this.

$$\dfrac{t}{10}+\dfrac{t}{15}=1$$

Write as a decimal.

The power at Ice Station Lion is supplied via solar cells. Once a year, a plane flies in and sells solar cells to the ice station at a price of $20 per cell. Because of uncertainty about future power needs, the ice station can only guess the number of cells that will be required during the coming year (see probability distribution in Table 6). If the ice station runs out of solar cells, a special order must be placed at a cost of$30 per cell. a. Assuming that the news vendor problem is relevant, how many cells should be ordered from the plane? b. In part (a), what type of cost is being ignored? TABLE 6:

$$\begin{matrix} \text{No. of Cells} & \text{Probability}\\ \text{50} & \text{.20}\\ \text{60} & \text{.15}\\\text{70} & \text{.30}\\ \text{80} & \text{.10}\\ \text{90} & \text{.15}\\\text{100} & \text{.10}\\ \end{matrix}$$

state the domains and ranges of f and f^-1. f(x) = √x+1.

Mark and Amanda Carter own an appliance store and a restaurant. The appliance store sells merchandise on a 12-month installment plan; the restaurant sells only for cash. Which of the following statements are true? (More than one answer may be correct.)\
a. The appliance store has a longer operating cycle than the restaurant.
b. The appliance store probably uses a perpetual inventory system, whereas the restaurant probably uses a periodic system.
c. Both businesses require subsidiary ledgers for accounts receivable and inventory.
d. Both businesses probably have subsidiary ledgers for accounts payable.

A person working on the transmission of a car accidentally drops a bolt into a tray of oil. The oil is 5.00 cm deep. The bolt appears to be 3.40 cm beneath the surface of the oil, when viewed from directly above . What is the index of refraction of the oil?

How does demand help societies determine WHAT, HOW, and FOR WHOM to produce?

Demand for a product means more than simply the desire to own it. Instead, demand includes desire and also the willingness and ability to buy the product. Firms often try to influence demand in a number of different ways. To see how, analyze a television, print, or online ad for a product. What devices has the seller used in the ad to stimulate demand for it? Pay attention to ways the seller may have made the product easier to buy.
