The acceleration due to gravity on Earth is $9.8 \mathrm { m } / \mathrm { s } ^ { 2 }$ A ball is thrown upward at an initial velocity of 15 m/s from a height of 1 m above the ground. Round answers to the nearest tenth. a) Write an equation for the height of the ball. b) What is the height of the ball after 1 s? c) After how many seconds does the ball land? d) What is the maximum height of the ball? When does this occur? e) Repeat parts a) to d) for a ball thrown on the Moon, where $g = 1.62 \mathrm { m } / \mathrm { s } ^ { 2 }$ f) Repeat parts a) to d) for a ball thrown on Jupiter, where $g = 23.1 \mathrm { m } / \mathrm { s } ^ { 2 }$

Determine whether the following disputes are verbal, factual, or some combination of the two. If verbal, discuss whether the dispute arises from vagueness or ambiguity. PENNY: In my mind, the use of marijuana should be legalized. After all, caffeine and alcohol are no less of a drug than marijuana, and it’s not illegal to enjoy a glass of beer or drink a cup of coffee. SAM: Your conclusion is way off. Beer and coffee are not drugs; they’re foods.

A product can be produced on four different machines. Each machine has a fixed setup cost, variable production costs per-unit-processed, and a production capacity given in Table 15. A total of 2,000 units of the product must be produced. Formulate an IP whose solution will tell us how to minimize total costs. TABLE 15: $$ \begin{matrix} \text{Machine} & \text{Fixed Cost (\$)} & \text{Variable Cost per Unit (\$)} & \text{Capacity}\\ \text{1} & \text{1,000} & \text{20} & \text{900}\\ \text{2} & \text{920} & \text{24} & \text{1,000}\\ \text{3} & \text{800} & \text{16} & \text{1,200}\\ \text{4} & \text{700} & \text{28} & \text{1,600}\\ \end{matrix} $$

J. R. Carrington has $4 million to invest in three oil well sites. The amount of revenue earned from site i(i = 1, 2, 3) depends on the amount of money invested in site i (see Table 10). Assuming that the amount invested in a site must be an exact multiple of$1 million, use dynamic programming to determine an investment policy that will maximize the revenue J. R. will earn from his three oil wells. TABLE 10: $$ \begin{matrix} \text{Amount Invested (\$ Millions)} & \text{Revenue (\$ Millions)}\\ \text{ } & \text{Site 1} & \text{Site 2} & \text{Site 3}\\ \text{0} & \text{4} & \text{3} & \text{3}\\ \text{1} & \text{7} & \text{6} & \text{7}\\ \text{2} & \text{8} & \text{10} & \text{8}\\\text{3} & \text{9} & \text{12} & \text{13}\\ \text{4} & \text{11} & \text{14} & \text{15}\\ \end{matrix} $$
