Adult Weight from Puppy Weight There is a formula that estimates how much your puppy will weigh when it reaches adulthood. The method we present applies to medium-seized breeds. First, find your puppys weight w at an age of a weeks, where a is 16 weeks or less. Then the predicted adult weight W=Wa,w, in pounds, is given by the formula W=52wa In this exercises, we consider puppies that weigh w=5 pounds at age a. a. Write a formula for W as a function of the age a. b. Make a graph of W for ages up to 16 weeks. c. Does a weight of 5 pounds at an early age indicate a larger or smaller adult weight than a weight of 5 pounds at a later age? d. Is the graph concave up or concave down? Explain the meaning of the concavity in practical terms.
Enlarging a Field A farmer has a rectangular cow pasture with width 100 ft. and length 180 ft. An increase the number of requires the farmer to increase the area of her pasture. She has two options: Option 1: Increase the length of the field. 0ption 2: Increase the width at the field. It costs $10 per foot to install new fence. Moving the old fence costs $6 per linear foot of fence to be moved. (a) For each option, find a formula for A, the area gained, in terms of the cost C. (b) Complete the table for the area gained in terms of the cost for each option. (c) If the farmer has $1200 for this project, which option gives her the greatest gain in area for her money? What if she had $2000 for the project?
The Skydiver Again When a skydiver jumps from an airplane, her downward velocity, n feet per second, before she opens her parachute is given by = 176 1 0.834t, where t is the number of seconds that have elapsed since she jumped from the airplane. We found earlier that the terminal velocity for the skydiver is 176 feet per second. How long does it take for her to reach 90 of terminal velocity?
Harris-Benedict Formula Your basal metabolic rate is the amount of energy in calories your body needs to function at rest. The Harris-Benedict formula is used to estimate the basal metabolic rate. There is one formula for adult males and another for adult females. In these formulas, w is your body weight in pounds, h is your height in inches, a is your age in years, M=M(w,h,a) is the basal metabolic rate for adult males, and F=(w,h,a) is the basal metabolic rate for adult females: M=66+6.3w+12.7h6.8aF=655+4.3w+4.7h4.7a Use functional notation to express your own basal metabolic rate, and then calculate its value.
Cell Phone Plans Gwendolyn is mulling over the three cell phone plans shown in the table. From past experience, Gwendolyn knows that she will always use more than 1 GB of cell phone data every month. (a) Make a table of values that shows the Cost of each plan for 1 GB to 4GB, in 500 MB increments. (b) Find formulas that give Gwendolyn’s monthly cost for each plan, assuming that she use x gigabytes of data per month (where x1 ). (c) What is the charge from each plan when Gwendolyn uses 2.2 GB? 3.7 GB? 4.9 GB? (d) Use your formulas from part (b) to determine the number of gigabytes of data usage for which: (i) Plan A and Plan B give the same cost. (ii) Plan A and Plan C give the same cost. (iii) Plan B and Plan C give the same cost.
pH of Saliva The pH of saliva is normally in the range of 6.4 to 7.0. However, when a person is ill, the persons saliva becomes more acidic. a When Marco is sick, he tests the pH of his saliva and finds that it is 5.5. What is the hydrogen ion concentration of his saliva? b Will the hydrogen ion concentration in Marcos saliva increase or decrease as he gets better? c After Marco recovers, he tests the pH of his saliva, and it is 6.5. Was the saliva more acidic or less acidic when he was sick?
