Yes y=x^2 is a function because Using the definition of a function, y=x^2 is a function because for every x-value in your domain, you will only get 1 unique y-value. A quick check you can do is to use the vertical line test
Answer:
29
Step-by-step explanation:
Sum of the 21 numbers is 21*30 = 630
Now let's remove 50 from the sum of 630
630-50 = 580
The new average can be found. Remember we removed the largest number so we now have 20 numbers.
580/20 = 29

A car can travel for a distance of 350 miles in = 20 gallons
The car can travel for a distance of 1 mile in = (20/350) gallons
= 2/35 gallons
Then
The same car can travel for a distance of 875 miles in = (2/35) * 875 gallons
= 1750/35 gallons
= 50 gallons
So it can be seen that 50 gallons of gasoline is required to travel for a distance of 875 miles. I hope the procedure is clear enough for you to understand.
First you need to find the circumference of the circle because 1 revolution is 1 length of the circumference. The formula for the circumference is C=2πr or C=πd, if the diameter is 1 meter then the circumference is π1 which is just π, and if it travelled 8000 rotations then that would mean it travelled 8000π, so it travelled 8000π in meters
