Answer:
The question gives you V0 as 220, so plug that in first.
h=-16t2+220t.
Then it says to find the time (solve for t), when the height is 400 ft. Plug 500 ft in as h and solve for t.
500=-16t2+220t.
To solve this, set the quadratic equal to 0 by subtracting 500 from both sides (0=-16t2+220t-500) and use the quadratic formula!
Step-by-step explanation:
Its 264.
This is because its looking for the lateral surface area. And the formula for that is S=Ph.
So that means you add up the perimeter and multiply the height.
Answer:
B
Step-by-step explanation:
ok so since the two pieces added together just be 96 inches, we know that
x+y=96
that already eliminates everything but B.
let's keep going though.
let's have y be the piece that is 6 inches longer than double the length of the other piece.
y=2x+6
