Is it going to (120/100) * 85? Or is that wrong?

A curve has equation y= x^3+ 3x^2 -9x+k, where k is a constant.

1/ write down an expression for dy/dx

2/ find the x-coordinates of the two stationary points on the curve.

3/ hence find the two values of k for which the curve has stationary point on the x-axis.

Dy/Dx= 2√x - (2/√x)

Dy/Dx= 2√x - (2/√x)

In an arithmetic progression, the 1st term is -10, the 15th term is 11 and the last term is 41. Find the sum of all the terms in the progression. Plz help.

There used to be an extension named "x", which clears the cookies ryt? Its a security managing extension, it does not exist now. Any similar extensions like that?

The water levels in a dock follow (approximately) a twelve-hour cycle, and are modelled by the equation D = A + Bsin30t° , where D metres is the depth of water in the dock, A and B are positive consonants, and t is the time in hours after 8 a.m.

Given that the greatest and least depths of water in the dock are 7.80m and 2.20m respectively, find the value of A and the value of B.

Find the depth of water in the dock at noon, giving your answers correct to the nearest cm.

What if i heat a bunch of magnets and dissolve it in some substance? If i can do that could you please suggest me some substance thats usually at home. And btw im makin ferro fluid for my science fair, i couldnt get micr toners so plzz help me.

This is for ferro fluid, what type of magnets can i use to prove this experiment?

I have a physics exhibition or you could call it a science fair, but i have to do something with magnets, can u plz help me, anything possible to make. It shouldnt be very tough but it should be good for a high school student.
