Find u′(1)

Find or evaluate the integral by completing the square. (Round your answer to three decimal places.) Boundary is from 2 to 3. ∫ (2x-3)/ (√(4x-x2) dx

A company produces mattresses and wishes to maximize its profit. The cost, in dollars, for x mattresses can be modeled by the function C(x) = 18000 + 400x – 3.5x2 + 0.002083x3. The demand...

Use both the shell and disk methods to calculate the volume of the solid obtained by rotating the region under the graph of f(x)=3-x3 for 0<=x<=10/3 about the x axis.

A water tank in the shape of a hemispherical bowl of radius 4 m is filled with water to a depth of 2 m. How much work is required to pump all the water over the top of the tank? (The density of the...

Set up, but do not evaluate, the integral which gives the volume when the region bounded by the curves y = Ln(x), y = 1, and x = 1 is revolved around the line y = −1

What is the inverse of f(x)= x^(3/5)+1 Thanks

need help

I don't understand how to find an acute angle between 3y= x - 7 and 2y= 3 - 4x. Could you help me?

A stone is thrown into a lake and a circular ripple moves out atba constant speed of1m/s. Find the rate of change of surface area at the instant when its radius is 2m.

Use the differential equation and the given point to find f(x). dy/dx= (-48)/(3x+5)^2 Point: (-1,3)

Let g(x,y)=(xy)^(1/3). a. Is g continuous at (0,0)? I put down yes since it's not undefined there. b.Calculate ∂g/∂x and ∂g/∂y when xy≠0. This wasn't too bad and...

Here's the question: Find the most general function f:R^2 --> R such that ∇f(p)=p for each p∈R^2. So, I'm guessing this means that I just need to find a function of x and y...

Is f(x,y)=sqrt(x^2+y^2) differentiable at (0,0)? Justify. I don't think the partial derivatives exist due to the limit definition, so can I say that the function isn't differentiable...

what is the arcsin(1)?
