Answer:
Cricket will make 198 chirps per minute when temperature is 100 degrees.
Step-by-step explanation:
We are given the following in the question:
a) The number of chirps per minute, C, that the tree cricket makes is linearly dependent on the temperature, T, in Fahrenheit.
Let this relation be given by the linear equation:
where a and b are constants.
The crickets do not chirp at all below 45 degrees.
When the temperature is 45 degrees, C(T) = 0
Thus, we can write,
At 85 degrees they chirp about 144 times per minute.
Solving the equation, we get,
b) chirps per minute will crickets make at 100 degrees
We put T = 100 in the above equation,
Cricket will make 198 chirps per minute when temperature is 100 degrees.
