It is not because always remember, a positive is greater than a negative. This equation is showing a negative being greater than a positive. That's like saying I'm taller than you.
N/2=-12 multiply both sides by 2
n=-24
So the number is -24
Answer:
3.1 seconds
Step-by-step explanation:
The time it will hit the ground is when the <em>height is equal to 0</em>. So we plug in 0 in h and solve the quadratic equation for t.

We will use the quadratic formula [
] to solve this.
a is -16
b is 40 , and
c is 30.
plugging these into the formula we get:

Since time cannot be negative, we take t = 3.1 as the value
So it will take 3.1 seconds to hit the ground (target)
