Starts at 1,000feet
Each second is getting 20 feet closer to the surface since is ascending ( going higher)
1,000/20= 100/2=50 second it takes to reach the surface
That is called an improper fraction.You multiply the whole numbers by the denominator and then add what is left over to get the improper fraction.
100-21=79
2859(0.79)^3=1409.598
worth $1409.60
Y-intercept is (0,4)
Hope this helped!
