Conceptual Applications Assignment #2
1. . A rooster crows more frequently when the temperature is higher. Each time the temperature (degrees Fahrenheit) increases by 5 degrees, the rooster crows an additional 1 time each minute. Let x = the number of times the rooster crows per minute. Let y = temperature. The rooster crows 8 times per minute when the temperature is 70 degrees.
a. Write an equation that represents the situation.
b. Use your equation to calculate the number of crows per minute when the temperature is 90 degrees.
c. Mr. Cutter’s pet rooster is crowing like crazy (16 times per minute, to be exact). What temperature is it? Explain how you found your answer.
d. If a rooster crows only once every two minutes, will a glass of water freeze if left outside overnight? Explain.
4. A dog barks less frequently when the temperature is higher.
Each time the temperature increases by 1 degree, the dog barks 2 fewer times per hour. Let x = the number of barks per hour. Let y = temperature. The dog will bark 10 times per hour when the temperature is 85 degrees.
a. Write an equation that represents the situation.
b. Use your equation to calculate the number of barks per hour when the temperature is 64 degrees.
c. If the dog is barking 30 times per hour, what is the temperature outside?
d. How hot would it need to be for the dog to stop barking altogether?
