Using the average rate of change, it is found that the average rate is of:
(1) 2.1 °F per minute
<h3>What is the average rate of change of a function?</h3>
It is given by the <u>change in the output divided by the change in the input</u>.
In this problem:
- At 15 minutes, the temperature was of 90ºF.
- At 45 minutes, the temperature was fo 153ºF.
Hence, in 30 minutes, the temperature increased 63ºF, hence the rate is given by:
r = 63/30 = 2.1 °F per minute.

Answer: 34.29cm
Step-by-step explanation:
From the question, we are informed that Billy has 2.4 m of ribbon for crafts and that he wants to share it evenly with 12 friends.
The number of centimeters of ribbon that each of the 7 friends would get will be gotten by dividing 2.4m by 12. We can solve this by first converting 2.4meters to centimeters. This will be:
= 2.4meters = 2.4 × 100cm = 240 centimeters.
We then divide 240cm by 7. This will be:
= 240cm/7
= 34.29cm
The equation of the graph y=
has no symmetry
The equation of the graph y = 
Replace y with -y in the given equation
-y = 
When replacing y with -y gives the different equation. The equation is not symmetric with respect to x axis
Replace x with -x in the given equation
y = 
y = 
When replacing x with -x gives the different equation. The equation is not symmetric with respect to y axis
Replace x with -x and y with -y in the equation
-y = 
-y = 
When replacing x with -x and y with -y gives the different equation. The equation is not symmetry with respect to origin.
Hence, the equation of the graph y=
has no symmetry

Answer: Reagan's pay was increased by 62%
Step-by-step explanation:
First, lets find the difference between the two pays:
$347,247 - $214,350 = $132,897
Let 214350 = 100%
Dividing 132,897 by 214350 to find the percent increase

Therefore, Reagan's pay was increased by 62%
