Answer:

(9y²-4xy+4x²/9)/(3y-2x/3)

={(3y)²-2(3y)(2x/3)+(2x/3)²}/(3y-2x/3)

=(3y-2x/3)²/(3y-2x/3)

=(3y-2x/3)

<h3>(3y-2x/3) is the right answer.</h3>

Step-by-step explanation:

Notice that

9y² - 4xy + 4x²/9 = (3y - 2x/3)².

Therefore (9y² - 4xy + 4x²/9) / (3y - 2x/3)

= (3y - 2x/3).

telo118 [61]

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
