The temperature t in degrees fahrenheit is (approximately) a linear function of the number c of cricket chirps per minute. twenty cricket chirps per minute corresponds to a temperature of 42 degrees fahrenheit. each additional chirp per minute corresponds to an increase of 0.25 degree.(a) use a formula to express t as linear function of c. t =(b) what temperature is indicated by 100 cricket chirps per minute?

a) T= 0.25 C+37

b) T= 62°F

Step-by-step explanation:

Here T is a linear function of C

T= mC+b

For each additional chirp C corresponding to an increase in T of 0.25

therefore, m= 0.25

T= 42° F   C=20 ( given)

therefore,

a) 42= 0.25×20+b

b= 37

therefore T= 0.25 C+37

b) now C= 100

therefore, T= 0.25×100+37 = 62°F

you never say the total so we cant find the percentage used for petrol
