X2 - 8x + 15 = 0
(x - 3)(x - 5) = 0
critical points are at 3 and 5
What is the opposite of -|-1| so what is the opposite of -1? It's 1!!! Hope this helped!
Answer:
x-3=-3
Step-by-step explanation:
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)
