Answer:
it will take 5.5 seconds to hit the ground
Step-by-step explanation:
A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by 
When the projectile hits the ground then the height becomes 0
GCF is -8t
now set each factor =0 and solve for t
So it will take 5.5 seconds to hit the ground
Answer:
B
Step-by-step explanation:
I dont get the first statemet, that 2 angles are 90 degrees, because that isnpt possible for a triangle, but a triangle must add up to 180 degrees, and if you have one that is 90 degrees, then you are half way there, then you get 50 more degrees, and you have 40 left, so B is the answer angle C is 40 degrees,
PLS MARK BRAINLIEST IF YOU CAN :)
The resulting equation has a leading degree of 2, hence the system of equation will have 2 solutions
<h3>Quadratic equations</h3>
Quadratic equations are equations that has a leading degree of 2. Given the following system of equations
y=2x
y=x^2+2
Equate to have:
2x = x^2+ 2
Equate to zero
x^2 - 2x +2 = 0
Since the resulting equation has a leading degree of 2, hence the system of equation will have 2 solutions
