Answer:
The ball will reach the ground when h=0.
Set the equation equal to 0.
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
,
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 $t$.
Solve the equation using the Zero Product Property.
So,
Answer: 162000 seconds
Step-by-step explanation: There are 162000 seconds in 45.0 hours.
Answer:
The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.
Step-by-step explanation:
We take the estimate from the website, and expand for all buyers, to find the proportion that use their smartphones.
400 users of the website were randomly sampled from the existing database and 180 were found to have used their smart phones.
180/400 = 0.45
The best estimate for the proportion of ticket buyers that make purchases using their smart phones is 0.45.
(60x2)+30 = 150 miles
30 = 1/2 of 60 which is half an inch
60 x2 because he travels 2 inches
You gotta round the be to 100,000
