Answer:
175 minutes
Step-by-step explanation:
Add up the 8 different times then divide by 4 to get the average driving time for 1 day:
⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138
⇒ 138 ÷ 4 = 34.5 mins
Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:
⇒ 34.5 x 5 = 172.5 minutes
As 172.5 ≈ 175 minutes, the nest response is 175 minutes
(2 x 100,000) x (3 x 1,000,000) x (7 x 10,000,000) = 200,000 x 3,000,000 x 70,000,000 = 4.2^19 or 42,000,000,000,000,000,000
The exponential function that represents the table is 
<h3>What is an exponential function?</h3>
An exponential function is any function that has its constant raised to the power of an argument.
An exponential function is represented as:

Where:
- a represents the initial value
- b represents the rate
From the table we have the following ordered pair
(x,y) = {(0,2) (1,8)}
So, we have:



Also, we have:



Divide both sides by 2

So, we have:


Hence, the exponential function is:
