A ball is thrown into the air with an upward velocity of 28 ft/s. Its height (h) in feet after t seconds is given by the functio
Yanka [14]
The Answer is D: 

h = -16t^2 + 28t + 7
h' = -32t + 28

-32t + 28 = 0

-32t = -28 

t = .875 seconds

h(.875) = -16(.875^2) + 28(.875) + 7

h(.875) = 19.25 ft
Rounding time to nearest hundredth gives max at (.88s, 19.25ft)

The titanic had about half as many plates as they did pieces of silverware .About how many plates did they have ?
Korvikt [17]

Answer:

The answer is below

Step-by-step explanation:

1) Since the titanic was scheduled to reach on April 17 after leaving on April 10, this means that 7 days was spent on the voyage. The total amount of meat available was 75000 pounds, hence:

number of meat per day = total amount of meat / number of days = 75000 / 7 = 10714 pounds per day.

2) Total number of silverware is 44000. Hence:

Total plates = half of total silverware = 44000/2 = 22000

3) There are 3000 potatoes in a ton, and a total of 40 tons was available on the titanic. Hence:

Total number of potatoes = 40 tons * 3000 potatoes per ton = 120000 potatoes
