Answer:

The ball will reach the ground when h=0.

Set the equation equal to 0.

0=-8(2 t-4)(t+1)

t=-1,2

Step-by-step explanation:

The height of a golf ball after it has been hit from the top of a hill can be modeled by the equation

h=-8(2 t-4)(t+1),

where h is the height in feet and t is time in seconds.  

When ball will reach the ground the distance between ball and ground is 0. So, the ball will reach the ground when h=0.

To find the time it takes for the ball to reach the ground,  set the equation equal to 0 and use the Zero Product Property to solve for $t$.

h=-8(2 t-4)(t+1)

\Rightarrow 0=-8(2 t-4)(t+1)

Solve the equation using the Zero Product Property.

2t-4=0\Rightarrow t=\dfrac{4}{2}=2

t+1=0\Rightarrow t=-1

So, t=-1,2

At the city museum, child admission is $5.20 and adult admission is $8.90 . on friday, 159 tickets were sold for a total sales o
Zinaida [17]
Total tickets sold = 159
Total sales = $1100.60
Child admission = $5.20
Adult admission = $8.90

Assumed all 159 tickets are Child admission tickets
Total sales = 159 x 5.2 = $826.80

Difference in amount = $1100.60 - $826.80 = $273.80
The difference must be contributed by the Adult Admission Tickets, which has a difference of $8.90 - $5.20 = $3.70

$273.80 ÷ $3.70 = 74 adult tickets

159 - 74 = 85 child tickets
