The mean of a group of numbers is found by dividing their sum by how many numbers there are.

Mean=(1+7+25+9+34)/5=76/5=15.2

Write as y=uv u=x v=e^x

du/dx=1 dv/dx=e^x 

Using the product rule, dy/dx=vdu/dx + udv/dx

So dy/dx=e^x(1)+x(e^x...

All of this is to do with moving stuff over a barrier called a cell membrane.

I want you to imagine the cell membrane to be like a border of a country and the stuff to be different pizzas...

y = 2x^2 + 4x - 8y = 2( x^2 + 2x - 4)Completing the square:y = 2( (x+1)^2 - 1 - 4 )y = 2(x+1)^2 -10the vertex of graph lies at the minimum value of y, and this occurs when x = -1:y = 2(-1+1)^2 -10y = -10t...

You're right, there aren't that many devices in London. That's not a problem, though. 

Your question gives you a lot of help. You're looking for powerlessness and how it's presen...
