When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0=-(x-2)^{2}+16 \\  \\ 
(x-2)^{2}=16 \\  \\ 
x-2= \sqrt{16} \\  \\ 
x-2=4 \\  \\ 
x=6

This means the ball will hit the ground 6 seconds after Amir threw it

CaHeK987 [17]

Given:

Carol has 88cm of string and cuts it in the ratio 5 : 6.

To find:

How much longer is the longest piece compared to the shortest piece.

Solution:

Let the lengths of two pieces of string are 5x and 6x. Then,

5x+6x=88

11x=88

x=\dfrac{88}{11}

x=8

Now, the lengths of pieces are:

5x=5(8)

5x=40

And,

6x=6(8)

6x=48

The difference between the longer piece and shorter piece is:

48-40=8

Therefore, the longer piece is 8 m longer than the shorter piece.
