Well, it is pretty hard to type here. I'll put it in words. Hope you get it.

Left hand side (LHS) of the equation:
x to the power √x³ to the power ³√x

Right Hand Side (RHS) of the equation:
(x√x)^(x)


Now, find the sum of the positive roots of the equation.

How do you factorize f(x)=2x^3+4x^2+5x+3

to obtain this form of equation f(x)=(x+1)(ax^2+bx+c)?
thanks a lot!!

Alright, quick background... This problem is a "look back" for my Calculus class & for some reason, I cannot figure out where to go...

Question:
"A cattle rancher has 2300 feet of fencing that will be used to enclose a rectangular feed lot. If one of the dimensions of the feed lot is x , find a formula for the area y of the feed lot (in square feet) as a function of x."

My proposed Answer (not yet complete, but this is what i have so far)
2x+2y=2300
x+y=1150
x*y= ?

now what??

Please help! Thank you!

The driver of a vehicle on a level road determined that she could increase her speed from rest to 50 mi/h in 34.8 seconds and from rest to 65 mi/h in 94.8 seconds. If it can be assumed that the acceleration of the vehicle takes the form du/dt = alpha - (beta)u determine the maximum acceleration in each case. Where alpha and beta are constants and u is the vehicle speed in ft/sec.
