If f(x)=7xe^x, find f'(x)

f(x) = 7xexUsing the product rule: [f'(x)=u*(dv/dx)+ v*(du/dx)]Let u=7x and v=exTherefore, du/dx=7 and dv/dx=exHence, f'(x) = 7xex + 7ex

The curve has the equation y= (x^3)/(2x-1). Find dy/dx.


Suppose a population of size x experiences growth at a rate of dx/dt = kx where t is time measured in minutes and k is a constant. At t=0, x=xo. If the population doubles in 5 minutes, how much longer does it take for the population to reach triple of Xo.


A curve (C) with equation y=3x^(0.5)-x^(1.5) cuts the X axis at point A and the origin, calculate the co-ordinates of point A.
