for all integers x, 1/x less than or equal to x
Hi there! :)
Answer:
Use the formula V = 1/3(bh) to solve for the volume of the cone where b = πr² where π ≈ 3.14:
Find the area of the base:
b = π(7)²
b = 49π
b = 153.86 mm²
Find the volume:
V = 1/3(153.86 · 7)
V = 1/3(1077.02)
V = 359.006 ≈ 359.01 mm³.
A rocket is launched from the ground. The function h(t)= -4.9t^2 +180t models the height of a rocket launcher from the ground t seconds after it is launched. If all other factors remain the same, which of the following function models the height of a rocket above the ground after t seconds if it is launched from a platform 100 feet in the air? (1) h(t) = -4.9t^2 +280t (2) h(t) = -4.9t^2 +180t -100 (3) h(t) = -4.9t^2 +180t +100 (4) h(t) = -4.9t^2 +180 (t+100)
