During an experiment, a ball is dropped from a height of 205 feet. The formula h = -16t2 + h subscript 0 can be used to approximate the number of seconds t it takes for the ball to reach height h from an initial height of h subscript 0 in feet. Find the time it takes the ball to reach the ground.

4 seconds

Step-by-step explanation:

where h=height reached after t seconds

          = Initial Height of the ball

The ball is dropped from a height of 205 feet,

= 205 feet

We want to determine the time it takes the ball to reach the ground.

i.e. when height of the ball, h=0

Substituting = 205 feet and h=0 into the formula

Add to both sides

Divide both sides by 16

≈ 4 Seconds

It takes approximately 4 seconds for the ball to reach the ground.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
