Y = -0.01x^2 + 0.5x + 3

when the height y = 8 
-0.01x^2 + 0.5x + 3 = 8
-0.01x^2 + 0.5x - 5 = 0

x =  13.82 and x = 36.18 so the ball is at least 8 ft high   from 13.82 and 36.18 feet inclusive.- from the player.

If the player is 30 ft from the net then the ball is likely to go over the net.

Which of the following best explains why
Dima020 [189]

We can see values of angles in degrees first

\frac{5\pi}{6}   = \frac{5 \times 180}{6}= \frac{900}{6} = 150°

Similarly

\frac{5\pi}{3}   = \frac{5 \times 180}{3}= \frac{900}{3} = 300°

Now reference angle means positive acute angle they will have

As we can see in attachment 150° lies in second quadrant so its reference angle will be 180°-150° = 30° from x axis line as shown.

Where as angle 300° lies in fourth quadrant so its reference angle will be 360° - 300° = 60° from x axis as shown. So clearly both reference angles are different . So 1st choice " angles donot have same reference angle" best explains it

Choice (2) and (3) are incorrect as tan is positive only in first and third quadrants and angle 300° is in fourth quadrant.

since angle 150° is in second quadrant and 300° is in fourth quadrant so both will have same negative sign so choice (4) is not correct.

So final ansewr is choice (1) "the angles donot have same reference angle"
