Question 151767This question is from textbook Elementary and Intermediate Algebra
: Bob and Betty simultaneously jump from two airplanes at different altitudes. Bob's altitude t seconds after leaving the plane is -16t^2+6600 feet. Betty's altitude t seconds after leaving the plane is -16t^2+7400 feet. Write a polynomial that represents that difference between their altitudes t seconds after leaving the planes. What is the difference between their altitudes 3 seconds after leaving the planes? This question is from textbook Elementary and Intermediate Algebra

Bob and Betty simultaneously jump from two airplanes at different altitudes. Bob's altitude t seconds after leaving the plane is -16t^2+6600 feet. Betty's altitude t seconds after leaving the plane is -16t^2+7400 feet. Write a polynomial that represents that difference between their altitudes t seconds after leaving the planes. What is the difference between their altitudes 3 seconds after leaving the planes?
:
d = difference
d = (-16t^2+7400) - (-16t^2+6600)
d = -16t^2 + 16t^2 + 7400 - 6600
d = 1800 ft, is the difference through-out the jump
