The Greenland ice sheet contains about $3$ million cubic kilometers of ice. If completely melted, this ice would release about $2.5$ million cubic kilometers of water, which would spread out over Earth's $340$ million square kilometers of ocean surface. How much would sea level rise?

Estimate the product. Use a bar diagram if needed.

If the population of the United States is approximately

$$3.0 \times 10 ^ { 8 }$$

and each person spends about $140 per year on ice cream, express the total annual spending on ice cream in scientific notation.

Sharon, age 28, is a single parent who earns $30,000 annually as a secretary at a local university. She is the sole support of her son, age 3. Sharon is concerned about the financial well-being of her son if she should die. Although she finds it difficult to save, she would like to start a savings program to send her son to college. She is currently renting an apartment but would like to own a home someday. A friend has told her that life insurance might be useful in her present situation. Sharon knows nothing about life insurance, and the amount of income available for life insurance is limited. Assume you are a financial planner who is asked to make recommendations concerning the type of life insurance that Sharon should buy. The following types of life insurance policies are available:

1. Five-year renewable and convertible term
2. Life-paid-up-at-age 65
3. Ordinary life insurance
4. Universal life insurance

• a. Which of these policies would best meet the need for protection of Sharon’s son if she should die prematurely? Explain your answer.
• b. Which of these policies best meets the need to accumulate a college fund for Sharon’s son? Explain your answer.
• c. Which of these policies best meets the need to accumulate money for a down payment on a home? Explain your answer.
• d. What major obstacle does Sharon face if she tries to meet all of her financial needs by purchasing cash-value life insurance?
• e. Assume that Sharon decides to purchase the five-year term policy in the amount of$300,000. The policy has no cash value. Identify a basic characteristic of a typical term insurance policy that would help Sharon accumulate a fund for retirement.

Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. The equation

$$( 2 x - 3 ) ^ { 2 } = 25$$

is equivalent to 2x - 3 = 5.

Write in the blank the linking verb in parentheses that agrees with the subject of each sentence.

A dark forest _______ actually several pieces of painted cardboard placed at the back of the stage. (was, were)

In an ice plant, $200 \mathrm{~kg}$ blocks of ice slide down a frictionless ramp that makes an angle of $\theta=10.0^{\circ}$ with the horizontal. To keep the blocks of ice from moving too quickly, they are restrained by an attached cable that is parallel to the ramp. If the blocks are temporarily held at rest on the ramp by the cable, what is the tension $T$ in the cable?

Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. If (2, 5) satisfies an equation , then (5, 2) also satisfies the equation .

The $30\text{-lb}$ package $A$ has a speed of $5 \mathrm{ft} / \mathrm{s}$ when it enters the smooth ramp. As it slides down the ramp which is $15\text{ ft}$ high from the ground, it strikes the $80\text{-lb}$ package $B$ which is initially at rest and at a height of $5\text{ ft}$ from the ground. The If the coefficient of restitution between $A$ and $B$ is $e=0.6$, determine the velocity of $B$ just after the impact.

Briefly explain why each of the following statement is false, or reword it to make it true.

Some bacteria employ lysozyme to liquefy the tissue gel and make it easier for them to get around.

Choose the letter of the best answer. A group of similar cells that perform a similar function is called a(n) a. cell. b. organ. c. tissue. d. organ system.

Write a balanced equation for the gaseous reaction between $\mathrm{N}_2 \mathrm{O}_5$ and $\mathrm{F}_2$ to form $\mathrm{NF}_3$ and $\mathrm{O}_2$.

A water jet strikes a cart. After striking the cart, the water is deflected vertically with respect to the cart. The cart is initially at rest and is accelerated by the water jet. The mass in the water jet is much less than that of the cart. There is no resistance on the cart. The mass flow rate from the jet is $10 \mathrm{~kg} / \mathrm{s}$. The mass of the cart is $100 \mathrm{~kg}$. Find the time needed for the cart to achieve a speed one-half of the jet speed.

Evaluate the following integrals. Include absolute values only when needed. $\int_{0}^{\ln 3} e^{x}\left(e^{3 x}+e^{2 x}+e^{x}\right) d x$
