Answer:
D. 1024 feet
Step-by-step explanation:
The height function can be written in vertex form as ...
f(t) = -16(t -2)^2 +1024
This has a maximum value of 1024 (feet) at t=2 (seconds).
The maximum height of the ball is 1024 feet.
_____
Rearranging to vertex form can be accomplished in a few steps:
-16(t^2 -4t) +960 . . . . . factor the leading coefficient from the variable terms
-16(t^2 -4t +4) +960 -(-16)(4) . . . . . add and subtract the square of half the linear term coefficient: (4/2)^2 = 4
-16(t -2)^2 +1024 . . . . . collect terms and put into vertex form
Find 3/4 of 24000
3/4 * 24000 = 18000
Divide by 40.
18000 / 40 = 450
So it will take 450 minutes for it to be 3/4 full.
Answer:
$7.28
Step-by-step explanation:
The average price, or the expected price, of any item in this specialty store is given by the weighted average of each item's price. That is, the sum of the products of each individual price by its corresponding sales mix:

I got 13 but you didn’t put any answer choices
Answer:
0
Step-by-step explanation:
while rounding the fraction to half,it is to remember that
anything less than 1/4 can be rounded to zero.
anything equal or 1/4 or greater and less than 3/4 can be rounded to 1/2.
anything greater than 3/4 and less than 1 can be rounded to one.
so,1/9<1/4
the value is 0.
