A student is given that point P(a, b) lies on the terminal ray of angle , which is between radians and 2 radians. The student uses the steps below to find cos . Step 1 Find the quadrant in which P(a, b) lies: P(a, b) is in Quadrant IV. Step 2 Use the point and the Pythagorean theorem to determine the value of r: , but since r must be positive, . Step 3 Determine cos . , where a and b are positive. Which of the following explains whether the student is correct? The student made an error in step 3 because a is positive in Quadrant IV; therefore, . The student made an error in step 3 because . The student made an error in step 2 because r is negative in Quadrant IV; therefore, . The student made an error in step 2 because using the Pythagorean theorem gives .

Brain weight B as a function of body weight W in fish has been modeled by the power function B = 0.007W2/3, where B and W are measured in grams. A model for body weight as a function of body length L (measured in centimeters) is W = 0.12L2.53. If, over 10 million years, the average length of a certain species of fish evolved from 14 cm to 23 cm at a constant rate, how fast was this species' brain growing when the average length was 19 cm? (Round your answer to four significant figures.)

A scientist is trying to determine whether the use of cell phone contributes to brain cancer. For his study, he compares the medical records of subjects who have been diagnosed with brain cancer to the records of healthy subjects. What is the most significant weakness in this type of study? The test groups must be unusually large to generate significant data. The relationship between cell phone use and cancer is difficult to determine. This type of study is expensive, and the data are difficult to analyze. This type of study must rely on medical records, which are inaccurate.
