Calculus
Find an equation for the tangent line of the function y=x+(4/x) at the point (2, 4). The equation of the tangent line is . You may enter the equation in any form.

Calculus
Let f(x)=−4−3x+2x^2. Use the limit definition of the derivative to find find fŒ(a)

Calculus
If a ball is thrown straight up into the air with an initial velocity of 95 ft/s, its height in feet after t seconds is given by f(t)=95t−16t^2 Find the average velocity for the time period beginning when t=1 and lasting (i) 0.5 seconds (ii) 0.1 seconds (iii) 0.01 second...

Physics
A roller coaster has a mass of 425 kg. It sits at the top of a hill with height 66 m. If it drops from this hill, how fast is it going when it reaches the bottom? (Assume there is no air resistance or friction.)

chemistry
The reaction of chlorine gas with solid phosphorus (P4) produces solid phosphorus pentachloride. When 63.5 g chlorine reacts with 28.5 g P4, which reactant is limiting?

statistics
if no preliminary sample is taken to estimate p, how large a sample is necessary to be 87% sure that the point estimate will be within a distance of 0.04 from p?
