Assume that each consumer has zero financial wealth at birth and that they have three lifecycles: youth, middle age, and old age. The first two periods are spent at work, while the third is spent at retirement. In the first period, they make $5, in the second,$25, and in the third, nothing. The real interest rate, inflation, and predicted inflation are all equal to zero. What was work pay at the start of life worth today, discounted? What is the maximum sustainable consumption level that will ensure equal consumption throughout the course of the three periods?

Where are phospholipids found in cells?

The applications in this section require solving equations similar to those that follow. Solve the below-given equation algebraically and graphically.

Numerical, Graphical, and Analytic Analysis A right circular cylinder is to be designed to hold $22$ cubic inches of a soft drink (approximately $12$ fluid ounces).

(a) Analytically complete six rows of a table such as the one below. (The first two rows are shown.)

Draw the Lewis structure for nitric acid (the hydrogen atom is attached to one of the oxygen atoms). Include all three resonance structures by alternating the double bond among the three oxygen atoms. Use formal charge to determine which of the resonance structures is most important to the structure of nitric acid.

In each of the following sentences, show where the correct punctuation marks should be inserted by underlining any word that should be followed by a colon and by drawing a caret ($\wedge$) to show where a semicolon should be inserted instead of a comma.

Example 1. The camp has no laundry facilities$\wedge$, be sure to bring all of the following $\underline{\text{items}}$ six complete changes of clothing, two pairs of sturdy shoes, a lightweight jacket, a hat, and a swimsuit.

8. Your mouth will feel a little sore this afternoon please eat soft foods for the rest of the day.

Rewrite the sentences in the negative using negative words. Follow the model. Modelo: Alguien illega. No llega nadie. Alguien va al laboratorio.

Indicate whether each of the following statements is correct or incorrect. Every Bronsted-Lowry acid is also a Lewis acid.

Consider the structure of cyclopentadiene and then answer the following questions:

Draw all resonance structures of the conjugate base of cyclopentadiene.

You and a partner are asked to complete a lab entitled "Oxides of Ruthenium" that is sched uled to extend over two lab periods. The first lab, which is to be completed by your partner, is devoted to carrying out composition al an alysis. In the second lab, you are to determine melting points. Upon going to lab you find two unlabeled vials, one containing a soft yellow substance and the other a black powder. You also find the following notes in your partner's notebook Compound 1: 76.0% Ru and 24.0% O (by mass), Compound 2 : 61.2% Ru and 38.8% O (by mass) Which compound is ionic?

Gross domestic product (GDP) is a major indicator of a nation’s overall economic activity. It consists of personal consumption expenditures, gross domestic investment, net exports of goods and services, and government consumption expenditures. The file GDP contains the GDP (in billions of current dollars) for the United States from 1980 to 2012.

a. Plot the data.

b. Compute a linear trend forecasting equation and plot the trend line.

c. What are your forecasts for 2013 and 2014?

d. What conclusions can you reach concerning the trend in GDP?

In a needle biopsy, a narrow strip of tissue is extracted from a patient with a hollow needle. Rather than being pushed by hand, to ensure a clean cut the needle can be fired into the patient’s body by a spring. Assume the needle has mass 5.60 g, the light spring has force constant 375 N/m, and the spring is originally compressed 8.10 cm to project the needle horizontally without friction. The tip of the needle then moves through 2.40 cm of skin and soft tissue, which exerts a resistive force of 7.60 N on it. Next, the needle cuts 3.50 cm into an organ, which exerts a backward force of 9.20 N on it. Find the maximum speed of the needle.

Compare the titration of a strong, monoprotic acid with a strong base to the titration of a weak, monoprotic acid with a strong base. Assume the strong and weak acid so lutions initially have the same concentrations. Indicate whether the following statements are true or false. The pH at the equivalence point is 7 no matter which acid is titrated.

Plants are green because of ____________, the main photosynthetic pigment in chloroplasts.
