The max height will be reached after 3 seconds.
You have a typo in your equation. For this type of quadratic equation, it always starts out with a negative coefficient of the t squared term.
To find the x-coordinate of the vertex, we just need to use the expression: -b/2a.
Then, we have:
-24 / (2(-4))
-24 / -8

Answer:
A, D
Step-by-step explanation:
When solving for x, we want to get all x terms on one side and all non-x terms on the other side. To make it so that x is by itself, we need to get rid of -3. We can do this by adding 3 to both sides, which demonstrates the addition property of equality. This property states that if you add a quantity to one side of an equation, you must add the same quantity to the other side as well.
 
        
             
        
        
        
Answer:
h(-8)= -14
Step-by-step explanation:
h(-8)= -2(-8 + 5)^2  + 4
h(-8)= -2(-3)^2  + 4
h(-8)= -2(9) + 4
h(-8)= -18 + 4
h(-8)= -14
