Answer :
The linear function that tells the temperature, c, of the compound t minutes after 9:00 a.m. is given by:
c(t) = 10 + 0.8t
What is a linear function?
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- Initially, at 9:00 a.m., the temperature is of 10 degrees celsius, hence b = 10.
- In 15 minutes, the temperature increased by 12 degrees, hence the slope is of m = 12/15 = 0.8.
Hence, the function is:
c(t) = 10 + 0.8t
