Answer:
6 cms.
Step-by-step explanation:
Volume of the pyramid = 1/3 * area of base * height
= 1/3 * 3*3 * h = 18
1/3 * 9 * h = 18
3h = 18
h = 6 cm
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:
(X²+2x+5)(2x)
= 2x(x²) +2x(2x) + 2x(5)
= 2x³ + 4x² + 10x
No. 16.454 has an extra number at the end. If the 4 at the end of 16.454 was a 0 then it wouldn't matter and they would be equal.
