Marie Curie discovered radiation. She was also the first person to use radiation to treat tumors. Curie experimented extensively with radioactivity during her scientific career. Unfortunately, the damaging effects of radiation were not known then. Her exposure to radiation most likely was the cause of her blindness and early death. Still today, her scientific papers are considered too dangerous to handle without protective equipment. These documents are stored in lead-lined boxes. Even her cookbook is radioactive. Curie sacrificed her own life in an attempt to help others save their own lives.

EXAMPLE 2 Find the extreme values of the function f(x, y)=2 x^2+5 y^2 on the circle x^2+y^2=1. SOLUTION We are asked for extreme values of f subject to the constraint g(x, y)=x^2+y^2=1. Using Lagrange multipliers, we solve the equations ∇f=λ ∇g and g(x, y)=1, which can be written as fx=λ gx fy=λ gy g(x, y)=1 or as (1) (2) =2 y λ (3) x^2+y^2=1. From (1) we have x= or λ=2. If x= , then (3) gives y= ± 1. If λ=2, then y= from (2), so then (3) gives x= ± 1. Therefore f has possible extreme values at the points (0,1),(0,-1),(1,0), and (-1,0). Evaluating f at these four points, we find that f(0,1) = f(0,-1) =5 f(1,0) = f(-1,0) =2 Therefore the maximum value of f on the circle x^2+y^2=1 is f(0, ± 1)= f( ± 1,0)=

We often deal with weighted means, in which different data values carry different weights in the calculation of the mean. For example, if the final exam counts for 50% of your final grade and 2 midterms each count for 25%, then you must assign weights of 50% and 25% to the final and midterms, respectively, before computing the mean score for the term. Apply the idea of weighted mean in the following exercise. A student is taking an advanced philosophy class in which the midterm and final exams are worth 35% each and homework is worth 30% of his final grade. On a 100-point scale, his midterm exam score was 83.1, his homework average score was 90.3, and his final exam score was 87.6. Complete parts (a) and (b) below. a. On a 100-point scale, what is the student's overall average for the class? His overall average is 86.8. (Round to the nearest tenth as needed.) b. The student was hoping to get an A in the class, which requires an overall score of 93.5 or higher. Could he have scored high enough on the final exam to get an A in the class? Select the correct choice below and fill in the answer box to complete your choice. (Round to the nearest tenth as needed.) A. Yes, if the student scored points or greater on a 100-point scale on the final exam, he could have earned an A in the class. B. No, in order for the student to have earned an A in the class, he would have had to score points or greater on a 100-point scale on the final exam, which is not possible.

The physician admitted the patient to the respiratory intensive care unit (ICU) to be monitored closely. His vital capacity was 3500 mL on admission but decreased to 700 mL during the subsequent 48 hours. During this time, he also developed mild difficulties in swallowing. Shortly after this development, the pulse oximeter alarm sounded and the physician was notified. Because the physician anticipated that the patient would require respiratory assistance for several weeks, a tracheostomy was performed using local anesthesia, and the patient was connected to a ventilator with an FIO2 of 0.3, intermittent mandatory ventilation (IMV) rate 12 / min, VT 0.8 L, and pressure support ventilation (PSV) mode. Twenty minutes later, his blood gas values were pH 7.43, PaCO2 38, HCO3- 23, PaO2 104, and SaO2 97%. The respiratory care practitioner entered a SOAP in the patient's chart. Based on these clinical data, how would you SOAP this patient?

A company manufactures goods that are sold exclusively by mail order. The director of market research needed to test market a new product. She planned to send brochures to a random sample of households and use the proportion of orders obtained as an estimate of the true proportion, known as the product response rate. The results of the market research were to be utilized as a primary source for advance production planning, so the director wanted the figures she presented to be as accurate as possible. Specifically, she wanted to be 95% confident that the estimate of the product response rate would be accurate to within 2%. Complete parts (a) through (d). a. Without making any assumptions, determine the sample size required. n = (Round up to the nearest whole number.) b. Historically, product response rates for products sold by this company have ranged from 0.5% to 6.7%.

Assume the risk-free rate is 2.5%. What are the Sharpe ratios for Stocks A and B? Do not round intermediate calculations. Round your answers to decimal places. Stock A: Stock B: Are these calculations consistent with the information obtained from the coefficient of variation calculations in Part b? I. In a stand-alone risk sense A is less risky than B. If Stock B is more highly correlated with the market than A, then it might have the same beta as Stock A, and hence be just as risky in a portfolio sense. II. In a stand-alone risk sense A is less risky than B. If Stock B is less highly correlated with the market than A, then it might have a lower beta than Stock A, and hence be less risky in a portfolio sense. III. In a stand-alone risk sense A is less risky than B. If Stock B is less highly correlated with the market than A, then it might have a higher b than Stock A, and hence be more risky in a portfolio sense. IV. In a stand-alone risk sense A is more risky than B. If Stock B is less highly correlated with the market than A, then it might have a lower beta than Stock A, and hence be less risky in a portfolio sense. V. In a stand-alone risk sense A is more risky than B. If Stock B is less highly correlated with the market than A, then it might have a higher beta than Stock A, and hence be more risky in a portfolio sense.

Molecules of four imaginary substances are sketched in the table below. Each sketch is shaded to show the electrostatic potential at the surface of the molecule. Rank these substances in decreasing order of the strength of the intermolecular forces in them. In other words, choose 1 next to the substance in which the molecules exert the strongest intermolecular forces on each other. Choose 2 next to the substance in which the molecules exert the second strongest intermolecular forces on each other, and so forth. Note: all of the molecules are neutral, and you may assume none of them experience hydrogen bonding.
