Answer:
Time t = 2 seconds
It will reach the maximum height after 2 seconds
Completed question;
Amir stands on a balcony and throws a ball to his dog who is at ground level. The ball's height, in meters above the ground, after t seconds that Amir has thrown the ball is given by:
H (t) = -(t-2)^2+9
many seconds after being thrown will the ball reach its maximum height?
Step-by-step explanation:
The equation of the height!
h(t) = -(t-2)^2 + 9 = -(t^2 -4t +4) + 9
h(t) = -t^2 +4t -4+9
h(t) = -t^2 + 4t +5
The maximum height is at dh/dt = 0
dh/dt = -2t +4 = 0
2t = 4
t = 4/2 = 2
Time t = 2 seconds
It will reach the maximum height after 2 seconds

Answer:
<u><em>Negative Correlation</em></u>
The variable x - value increases as y- value decreases is called negative correlation.
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Negative correlation:-
The negative correlation is a relation between two variables such that they are part of a function in which depends and independent variables move in different directions in terms of value.
<u><em>Positive correlation</em></u>
The variable x - value increases as y- value increases is called positive correlation.
<u><em>Negative Correlation</em></u>
The variable x - value increases as y- value decreases is called negative correlation.
<u><em>No correlation </em></u>
There is no pattern between two variables
there is no connect between two variables is called No - correlation
