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.

The calculation of the interest based on the price given shows that vehicle B has a lower interest.
<h3>How to calculate the price?</h3>
From the information given, vehicle A has a final sale price of $25,000 at 5% interest and financing up to 60 months. The interest will be:
= (25000 × 5 × 5)/100
= $6250
Vehicle B has a final sale price of $29,000 at 4% interest and financing up to 60 months. The interest will be:
= (29000 × 4 × 5)/100
= $5800
Therefore, the calculation of the interest based on the price given shows that vehicle B has a lower interest.

Answer:
False.
Step-by-step explanation:
The border line would be solid if the inequality is less than and equal to or greater than and equal to. In this case it is less than.
An equation has an infinite number of solutions if the left and right sides are identical. Let's simplify them both and then decide the value of ?.
Left hand side:

Right hand side:

So, both sides have a numeric part of -20. We can use the "?" value to make sure that the literal part is the same as well. So, we want
