Math Calculus
The function f is given by the formula f(x)=6x^3+17x^2+4x+21/x+3 when x<–3 and by the formula f(x)=2x^2–4x+a What value must be chosen for a in order to make this function continuous at -3?

Fluid Mechanics
Calculate the pressure at a point 5 m below the free water surface in a liquid that has a variable density given by equation o =(350+Ay)kg/m3, where A = 8 kg/m4 and y is the distance in meters measured from the free surface.

You do have to solve for the take-off speed, but I have the answers. I just don't know the procedure for solving the problem.

Physics
I just said the takeoff speed is 9.0 m/s.

Physics
ANSWER: Vo = 9.0 m/s She lands 0.21 m past the opposite bank I'm not sure how to get those numbers, though.

Physics
No, the initial velocity has to be solved for.

Physics Questions!
An interference pattern is set up by two point sources of the same frequency, vibrating in phase with one another. A point on the second nodal line is 50.0 cm from one source and 59 cm from the other. The speed of the waves is 35 cm/s. Calculate the frequency of the sources. I...

hmhm you could say an "oasis of serenity amidst the bustling city." Serenity means a peaceful or calm state. As to your second question, I am not sure.

Bobpursley for this question please, physics
I think I figured it out, you just switch the N and the mlambda, correct?

Bobpursley for this question please, physics
I dont understand though why you can make w/mlambda I thought it was the otherway around? (in regards to this w/N sinTheta= m lambda N= w/(m lambda) * sinTheta N= w/(m lambda) * x/L

Hello, we are doing a lab dealing with diffraction gratings. The problem I have is that we are supposed to find the number of slits, N, based on gathered information. I have x, L, d, m, and w, just not N, which is what I am trying to find. I also have the wavelength. Is this t...

Physics Lab
yes! It works I got an answer or 35.2 so there were approximately 35 slits! But wow, thanks soo much! This really saved me! I appreciate this!

CALCULUS
what is the derivative of ln(x-1)? If you are studying the calculus of logarithms your question surprises me, since that is one of the most basic ones in that topic. in general if y = ln("anything") then y' = 1/"anything" * derivative of "anything&...
