ja1 · Answer

$$H(t) = -16t ^{2} +  16t + 32$$
$$0 = -16t ^{2} + 16t + 32$$
A = -16 B = 16 C = 32
$$\frac{ -16 }{ 2(-16) }$$
$$\frac{ -16 }{ -32 }$$
$$\frac{ 1 }{ 2 }$$
0.5


$$H(0.5) = -16(0.5)^{2} + 16(0.5) + 32$$
$$H(0.5) = -16(0.25) + 16(0.5) + 32$$
$$H(0.5) = -4 + 8 + 32$$
$$H(0.5) = 36$$
$$(0.5,36)$$
Projectile will reach 36 feet in 0.5 seconds.

Is this right?

jdoe0001 · Answer

am I wrong or you should have gotten 2 answers from the quadratic?

ja1 · Answer

Yes but that one was the objective in this problem

jdoe0001 · Answer
