Answer:
11.78 inches
Step-by-step explanation:
The chain travel will equal the length of the 225° arc on the central gear. Arc length (s) is given by the formula ...
s = rθ
where θ is the central angle in radians. We know that 180° is π radians, so the chain travel is ...
s = (3 in)(225°)(π/180°) = 15π/4 in ≈ 11.78 in
<span>the quadratic function that is created with roots -3 and 1 is:
f(x) = a(x + 3)(x - 1) = a(x^2 + 2x - 3) = a(x^2 + 2x) - 3a . . . . . . . . (1)
</span><span><span>the quadratic function that is created with</span> vertex at (-1, -8) is:
a(x + 1)^2 - 8 = a(x^2 + 2x + 1) - 8 = a(x^2 + 2x) + a - 8 . . . . . . . . (2)
From (1) and (2): a - 8 = -3a
4a = 8
a = 2
Therefore, required function is f(x) = 2(x^2 + 2x) - 3(2) = 2x^2 + 4x - 6

14=42
42 in cubed
volume is length x width x height
you already have the area of the base of the shape so all you need to do is times is by the height to find the volume
