Answer:

Angle ABE = 58

Step-by-step explanation:

This would fulfill the AAA theorem, or 3 angles needing to be congruent. We got 58 by subtracting 89 and 62 from 180, then multiplying that answer by 2 (because it occupies both triangles).

The solutions are where the quadratic is equal to 0, or when the quadratic crosses the x axis.

Where the quadratic crosses the x axis are the solutions:

6) x = –5, x = –6

7) x = 0, x = 1

8) x = –6, x = 1

9) x = –4, x = –3

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
