Step-by-step explanation:
A ball is launched straight up in the air from a height of 6 feet. The velocity as a function of time t is given by :
f(t) = -32 t+285
Height of the ball is :

C is constant. Here the ball is launched from a height of 6 feet. So,

At t = 2 s, 
At t = 9 s, 
Between 2 s and 9 s, the ball's height changed is : 1275 - 512 = 763 m.
Answer:
V ≈ 1847.26
Step-by-step explanation:
<u>Circular Cone Formulas in terms of radius r and height h:</u>
The volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
The base surface area of a cone (a circle):
B = πr2
The total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Therefore, the solution
V = πr 2h
/ 3 = π·142·9/ 3 ≈ 1847.25648

Answer: 2.4 cm
Step-by-step explanation:
1.5 divided by 250 gives that each page is .006cm. 400 times .006 is 2.4cm
The perimeter is (2 lengths) + (2 widths). Since the perimeter is 18 inches, (1 length) + (1 width) must add up to 9 inches.
If the length and the width must both be whole numbers, the only possible choices for the side lengths of this rectangle are:
1 x 8 in
2 x 7 in
3 x 6 in
4 x 5 in .
