The equation below models the height in feet, h, of a softball t seconds after it is hit by a batter. h= -16t2+105t+3 why is the height of the ball a function of time? each value of time is associated with exactly one height. each height of the ball is associated with exactly one moment in time. there is exactly one time at which the maximum height is attained. there is a maximum and minimum height that the ball can reach.

-  Each value of time is associated with exactly one height.

Explanation:-

Given:- The equation models the height in feet (h) of a softball t seconds after it is hit by a batter.

Here h is the height of the ball a function of time where time(t) is an independent variable and 'h' is a dependent variable which depends on time.

⇒h is the height of the ball a function of time ∵ each value of time is associated with exactly one height.

50=33x+22

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
