For the last 4.5 hours, the temperature has decreased at a rate of 2.8 degrees per hour. which best represents the overall change in temperature over this time period?

a. -12.6 degrees
b. -1.6 degrees
c. 1.6 degrees
d. 12.6 degrees

Option A. -12.6 degrees

Step-by-step explanation:

It is given in the question that the temperature has decreased at a rate of 2.8 degrees per hour for the last 4.5 hours.

We have to calculate the change in temperature over this time period.

Overall change in temperature will be represented by

f(t) = -2.8(t)

where t is the time period for the change.

Now for t = 4.5 hours

f(4.5) = (-2.8) × 4.5

f (4.5) = -12.6 degrees

Option A. -12.6 degrees will be the answer.
