A plane is on its approach to land on the runway. The jet's height above the ground is given in feet as a function of the time in seconds. The following table tracks the plane as it lands: t (in seconds) n (in feet) 10 14000 15 3500 10 3000 115 2500 2000 20 25 1500

Calculate the slope. Use the formula m = What is the significance of the sign of the slope?

a. The plane is losing altitude.
b. The plane is gaining altitude.
c. The plane is remaining at a constant height.
d. The plane is losing altitude at a rate of 500 feet/second.

one set of data has more variation than the other. hope this !

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
