Check the picture below.

so then, the highest point will be at the y-coordinate of its vertex.

\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ h(t)=\stackrel{\stackrel{a}{\downarrow }}{-16}t^2\stackrel{\stackrel{b}{\downarrow }}{+48}t\stackrel{\stackrel{c}{\downarrow }}{+4} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)

\bf \left( \qquad ,~~4-\cfrac{48^2}{4(-16)} \right)\implies \left( \qquad ,~~4+\cfrac{2304}{64} \right)\implies (\qquad ,~4+36) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill (\qquad ,~~\stackrel{\stackrel{\textit{how high}}{\textit{it went}}}{40})~\hfill

Enter the number that belongs in the green box.
ale4655 [162]

Answer:

the green box is 0

Step-by-step explanation:

we are asked to find the <u>x-intercept</u>, which means y = 0

(x, y)

Another way to test this is plug it in 1 for x!  (1, y) where x = 1

y = \frac{2x^{2} -3x+1}{2x^{2} +8x+6} \\\\

y = \frac{2(1)^{2} -3(1)+1}{2(1)^{2} +8(1)+6}

y = \frac{2(1) -3(1)+1}{2(1) +8+6}

y = \frac{2 - 3 + 1}{2 + 8 + 6}

y = \frac{-1+1}{10 + 6}

y = \frac{0}{16}

y = 0
