Determine the equation 1 the tangent to the given function, at the given point. y = (3x^-2 - 2x^3) , @ (1,1)

The line y = 8x + b is tangent to the curve y = 2x^2. Determine the point of tangency and the value of "b"

A Tangent to the parabola y = 3x^2 - 7x + 5 is perpendicular to x + 5y - 10 = 0 Determine the equation of the tangent i really don't know where to start!

Ok so i came upon this question and i have no idea what to do! limit x->a x^n-a^n / x - a the answer is na^n-1

A couple of physics questions on helmets!? 1. Why is the impact force reduced for a helmet with a soft interior vs.a hard interior? 2. How is the safety reduced if the helmet does not fir properly? 3. Once a helmet has been involved in a collision, it should be replaced. why? 4. What...
