Homework Statement I need to find the equation of a plane with direction vectors <1,3,-1>/sqrt(11) and <-2,1,1>/sqrt(6) passing through the point (1,2,3) Homework Equations The Attempt at a Solution I'm not really sure what to do, I was considering taking the...

ok. i still can't figure out what the equation of the curve is... is it h^2?

since I'm revolving it around the y axis, how do i know what the length of the axis to the end of the bowl with the water is? I'm really confused

Homework Statement A hemispherical bowl of radius "a" contains water to a depth "h" Fine the volume of water in the bowl. Homework Equations Pi * Integral(R(x))^2 basically the disk method The Attempt at a Solution The answer is (Pi*h2*(3a-h))/3...i just have no idea...

I was just curious which degree would be highly sought after. Also on another note, what is the career outlook for optical engineering?

So then what? I have integral of (u+10)(u)^(1/3) du.

Homework Statement Evaluate the integral. Int((x+5)(x-5)^(1/3)dxHomework Equations The Attempt at a Solution I've attempted the problem but subsitution doesn't seem to do anything, as du = dx if u = x-5, which doesn't cancel anything.

anyone? does 21.5 deceleration make sense as an answer?

Ok so it would be v(t) = -at + 44...anyways I ahead and tried to solve the problem. Could anyone check my solution? He said to leave it in fraction form and I got a = 1936/90 or 968/45.

so if the derivative is going to be -a then v(t) = -44t + v0?

Homework Statement The State cycle program requires motorcycle riders to be able to brake from 30 mph(44ft/sec) to 0 in 45 feet. What constant deceleration does it take to do that? No physics formulas allowed. Homework Equations Integral rules and whatnot The Attempt at a...

Homework Statement L'Hopital's rule does not help with this limit. Find it some other way. lim (squarert(x)/squarert(sinx)) as x -> 0+ Homework Equations None? The Attempt at a Solution The only way I can think of solving this is by using L'Hopital's rule...but it obviously...

Maybe...I don't know this is from a previous test. I feel like she should've fixed this by now?

Homework Statement Find d2y/dx2 in terms of x and y for the following equation: xy + y^2 = 1 COMPLETELY SIMPLIFY Homework Equations dy/dx The Attempt at a Solution so i get -y/(x+2y) for the dy/dx. When I try to find the 2nd derivative and plug in dy/dx, I get...

Homework Statement piecewise...f(x) = {3, x=0 -x^2+3x+a, 0<x<1 mx+b, 1<= x <= 2 Homework Equations (f(b) - f(a))/(b - a) = fprime(c) The Attempt at a Solution I am just really lost at what this is trying to ask...sorry :( I tried plugging in stuff in the equation but I'm...
