According to the rate of change, it is found that the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.
<h3>What is the average rate of change?</h3>
The average rate of change of a function is given by the <u>change in the output divided by the change in the input.</u>
In this problem, it is stated that at the top of the mountain, the average rate of change is of -2.5 ºC per hour, and at the bottom of the mountain the rate is the same, hence the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.

Two events are mutually exclusive if they cannot occur in the same trial of an experiment.
A compass is used to copy an angle.
Answer:
x=10 x=-4
Step-by-step explanation:
x^2 +6x = 40
subtract 40 from each side
x^2 +6x -40 = 0
what numbers multiply to -40 and add to 6
-10 *4 = -40 -10 +4 = 6
(x-10) (x+4) = 0
using the zero product property
x-10 = 0 x+4 =0
x=10 x=-4
