Answer:

76.97 cm!!

Step-by-step explanation:

The equation for this would be V=π(d/2)^2h.  So, V= π (pi) (3.5/2)^2 8, so just solve that and you get the answer above!!

Y=x(sin(x)), 0 ≤ x ≤ 2π?
Lemur [1.5K]
Careful; (dy/dx)^2 = x^2 cos^2(x) + 2x sin x cos x + sin^2(x).

<span>So, the arc length equals </span>
<span>∫(x = 0 to 2π) √[1 + (x^2 cos^2(x) + 2x sin x cos x + sin^2(x))] dx </span>
<span>= ∫(x = 0 to 2π) √[1 + x^2 cos^2(x) + x sin(2x) + sin^2(x)] dx, via double angle identity. </span>

<span>Let Δx = (2π - 0)/10 = π/5. </span>
<span>Using Simpson's Rule with n = 10, this integral approximately equals </span>
<span>((π/5)/3) * [f(0) + 4 f(π/5) + 2 f(2π/5) + 4 f(3π/5) + 2 f(4π/5) + 4 f(π) + 2 f(6π/5) + 4 f(7π/5) + 2 f(8π/5) + 4 f(9π/5) + f(2π)], </span>

<span>where f(x) = √[1 + x^2 cos^2(x) + x sin(2x) + sin^2(x)]. </span>
<span>------- </span>

a woman jogging at 6mi/hr passes a man biking in the opposite direction at 12mi/hr. If they maintain their speeds, how far from
s344n2d4d5 [400]
The woman is moving at 6mi/hr which means 1mi per 10 minuets because 1 hour = 60 minuets and she is moving 6 mi every 60 minutes which means 1 mi every 10 minuets , same thing for that man 12 mi every hour = 2 mi every 10 minuets , and because of the opposite direction we will add 2 + 1 = 3mi after 10 minuets. I hope that helped u a little bit.
