I believe its already in standard form so you would just add it
Answer:
the projectile reached a maximum height of 27.6 meters in 2.4 seconds and it took 5.0 seconds for it to hit the ground
Step-by-step explanation:
to find the vertex you can find the axis of symmetry first
that equation is -b/2a
-19/-8 = 2.375
then you take this and plug it in
-4(2.375)^2 + 19*2.375 + 5
that gives you 27.5625
then you have to find when it hits the ground
you can factor to find this out
-4t^2 + 19t + 5
4t^2 - 19t - 5
4t^2 + t - 20t - 5
t(4t + 1) -5(4t +1)
(t - 5)(4t + 1)
t = {5, -1/4}
we can only take positive time so it took 5 seconds
the answer is the second one
Answer:
2
Step-by-step explanation:
5x + 3 = x + 11
5x - x + 3 = x - x + 11
4x + 3 = 11
4x + 3 - 3 = 11 - 3
4x = 8
4x / 4 = 8/ 4
x = 2
Hope this helps ^-^
X=12
This is because you subtract 6 from both sides to get the x isolated.
So x=18-6
x=12 :)
