Answer:
2.5 second
Step-by-step explanation:
The equation is missing in the question.
The equation is,
, where 'h' is the height and 't' is time measured in second.
Now we know to reach its maximum height, h in t seconds, the derivative of h with respect to time t is given by :

Now the differentiating the equation with respect to time t, we get


For maximum height, 
So, 



Therefore, the ball takes 2.5 seconds time to reach the maximum height.
Y=1/2 x so graph B i think.
The y intercept is -2, but I don't remember how to find the vertex sorry
G(-1) = -1+3
= 2
F(2) = 5(2) - 10
= 0
Answer:
The answer is "Expression: x+(x+2)".
Step-by-step explanation:
Given:
The sum of two consecutive even numbers
Proving:
Let,
The First number is = x
The second consecutive number is = x+2
Calculating value by adding value:
Expression:

when x= 1, 2, 3 .... it gives:

That's why the sum of consecutive numbers is even.
