The question is asking you to find the axis of symmetry, which is the x-value of the vertex. In order to do that you need to factor the function to find the zeros and add the zeros together and divide by two to find the axis of symmetry.
y=-16x^2+608x
y=-16x(x-38)
Zeros: x=0 and x=38
38/2=19
Therefore it takes 19 seconds for the projectile to reach its maximum height.
Hope this helps!
Answer:
Step-by-step explanation:
7/8 is 63/72
5/12 is 25/60
4/18 is 8/36
I’m glad that you love math keep it up though why don’t you answer the your questions but anyway I’m not here to judge just to answer
Now the answer is =-4 =-1 = 3 = 5 = 6
