An airplane pilot is fertilizing a field. The height y in feet of the fertilizer t seconds after it is dropped is modeled by y(t
zheka24 [161]

Answer:

About 360.178 feet

Step-by-step explanation:

So we want the vertical distance between the fertilizer and the ground to be 0.

This going to be about the time the pilot has dropped it

So we first need to find when y is 0.

0=-16t^2-3t+300

We are going to use the quadratic formula to solve for t:

a=-16

b=-3

c=300

The quadratic formula is:

t=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

t=\frac{3 \pm \sqrt{(-3)^2-4(-16)(300)}}{2(-16)}

t=\frac{3 \pm \sqrt{9+19200}}{-32}

t=\frac{3 \pm \sqrt{19209}}{-32}

t=\frac{3+\sqrt{19209}}{-32} \text{ or } \frac{3-\sqrt{19209}}{-32}

t \approx -4.424891774 \text{ or } 4.237391774

So the pilot has released it at about 4.237391774 seconds since the fertilizer has actually hit the ground at roughly this time.

So we want to know the horizontal distance at t=4.237391774:

85t

85(4.237391774)

360.1783008

360.178 feet

The box plot shows the ages of people at a movie screening. What percent of the people are between 20 and 37 years old?
iVinArrow [24]

Step-by-step explanation:

You didn't give the box plot, but to obtain the percentage of people between 20 and 37 years old, first of all, find the total number of people, T. Next, find the total number of people between 20 and 37 years old, t.

Then the percentage we want to find is:

P = T/t × 100
