Assuming Earth's gravity, the formula for the flight of the particle is:
s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160.
This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2.
Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet.

Answer:
3 3/8 cups of flour
Step-by-step explanation:
So, we know that 2 1/4 is the normal amount of flour you would use in the recipe. but you don't want to do normal. You want to make 1 1/2 times more than you usually do.
To do this, first figure out what half of 2 1/4 is.
(2 1/4) /2 = 1 1/8
Then, because you are looking to use 1 1/2 times more flour, simply add the 1 1/8 to the 2 1/4
You end up using 3 3/8 cups of flour.
