The chs baseball team was on the field and the batter popped the ball up. the equation f(x)=80t-16t^2+3.5 represents the height of the ball above the ground in feet as a function of time in seconds. how long will the catcher have to get in position to get to the ball before it hits the ground?

The catcher has less than 5 seconds to get the ball

Step-by-step explanation:

we have

This is a vertical parabola open down

we know that

The ball hit the ground when f(x)=0 -----> x-intercept of the function

Remember that the x-intercept of the function is the value of x when the value of the function is equal to zero

so

using a graphing tool

The x-intercept is for t=5 sec    

see the attached figure

therefore

The catcher has less than 5 seconds to get the ball

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9
