Answer:

Step-by-step explanation:
We are given that
Initial velocity=30 ft/s
Initial position=
We have to write a mathematical model for height of the softball by using the position equation
The position equation on Earth's surface is given by

Where
Initial velocity
=Initial position
Substitute the values in the equation then, we get

Hence, the mathematical model for height of the softball is given by

Answer:
x = 5
Step-by-step explanation:
Answer: 31.42 inches.
Step-by-step explanation:
Since the circumference of a circle equation is C = πd (also C = 2πr, in which 2*r = d), you can just substitute d = 10.
Then you get C = π*10 ≈ 31.42 inches.
Find how far the car can travel on one gallon of gas, by dividing total miles by number of gallons:
105 miles / 7 gallons = 15 miles per gallon.
Now multiply that by the number of gallons to find total miles:
15 miles per gallon x 9 gallons = 135 total miles.
