Answer: 23.2 miles per hour
Step-by-step explanation:
He ran 100 meters in 9.63 seconds.
First convert the number of meters he ran to miles:
= 100 * 3.28
= 328 feet
= 328/5,280
= 0.062121212 miles
Convert the seconds to hours:
= 9.63 / 60
= 0.1605 minutes
= 0.1605/60
= 0.002675 hours
Speed in miles per hour is:
= 0.062121212 / 0.002675
= 23.22
= 23.2 miles per hour
I think it would take her 1/20 of an hour to do each chore and i dont know what point a is .
We have been given the function

We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.

Now, we simplify this step by step.
First of all
. Thus, we have

Now, we can easily simplify it by PEMDAS


Therefore, the value of f(3) is 98.
Two million, nine thousand, three hundred forty five.
