At what point is the tangent to the curve defined by the function f(x) = 4x2-x+5 parallel to the line y-15x=1? Help!

Differentiate 2xy-17=-3x2 to find the slope at point (2,5). help?!

Differentiate y = (2x+5)^3(6x-1)^5. Express your answer in factored form.

how do you prove that the derivative of x^n is nx^n-1

y= 1/3x3+x2-35x+10 i)Determine the critical values and find out whether these critical values are maxima or minima ii) Determine the extreme values (y values) at the maxima...

Curve : dy/dx= 2-8(3x+4)^-0.5 The curve intersects the y-axis at y= 4/3 This is actually part 2, part 1 asked me to find dy/dt= 0.6 The gradient: dy/dx = -2 Find...

The velocity v m s –1 of a particle at time t seconds, is given by v = 2t + cos2t, for 0 ≤ t ≤ 2. (a) Write down the velocity of the particle when t = 0. When t = k, the acceleration...

I', really stuck on this one HW question: I have to show how dC/dt = (D * (d^2C/dx^2)) + P at steady state (so when cD/dt =0) equals: (d^2C/dz^2) + (Pa^2/D...

2. One of the simplest models says that the rate at which the number of individuals without access is decreasing (i.e. the rate at which individuals acquire internet access) is proportional to the...
