Hello.
Right now: we're learning about derivatives.
And the questions reads: Determine the coordinates of two points of tangency to the curve y=-2x^2, given that the corresponding tangent lines intersect at (2,8).
What I know:
I know that the derivative of the function is y'= -4x
I know...
Hello, I tried solving this but to no avail.
Maybe someone could help me figure out the answer, thanks.
A rock is dropped from a sea cliff and the sound is heard striking the ocean 3.0s later. If the speed of sound is 330 m/s. How high is the cliff?
