To find which value of \( x \) in the table is a solution to the equation \( 0 = -2536x^2 + 1623x \), we need to solve the quadratic equation.
First, we can factor the equation or use the quadratic formula if required, but here we can evaluate each value given in the table directly in the equation.
1. **Substituting \( x = 12 \)**:
\[
0 = -2536(12^2) + 1623(12)
\]
\[
= -2536(144) + 1623(12)
\]
\[
= -364224 + 19476 \neq 0
\]
2. **Substituting \( x = 24 \)**:
\[
0 = -2536(24^2) + 1623(24)
\]
\[
= -2536(576) + 1623(24)
\]
\[
= -1460160 + 38952 \neq 0
\]
3. **Substituting \( x = 36 \)**:
\[
0 = -2536(36^2) + 1623(36)
\]
\[
= -2536(1296) + 1623(36)
\]
\[
= -3283712 + 58368 \neq 0
\]
4. **Substituting \( x = 48 \)**:
\[
0 = -2536(48^2) + 1623(48)
\]
\[
= -2536(2304) + 1623(48)
\]
\[
= -5839360 + 77808 = 0
\]
After evaluating, we find that \( x = 48 \) is the solution to the equation \( 0 = -2536x^2 + 1623x \). Thus, the firework will reach the ground after traveling **48 feet**.
So, the correct response is:
**48 feet**.

\[

\]
\[

\]
4. **Substituting \( x = 48 \)**:
\[
0 = -2536(48^2) + 1623(48)
\]
\[
= -2536(2304) + 1623(48)
\]
\[
= -5839360 + 77808 = 0
\]
After evaluating, we find that \( x = 48 \) is the solution to the equation \( 0 = -2536x^2 + 1623x \). Thus, the firework will reach the ground after traveling **48 feet**.
So, the correct response is:
**48 feet**.
