Why does NaCl dissolve in water but not in cooking oil? Thank you for explaining this.

Science
I am figuring out how much KCL will dissolve in 50 grams of water at sixty degrees, based on a graph. According to the graph, 45 grams of KCL can dissolve at 60 degrees. So I subtracted 45 from 50, and got five. The thing is my book said the answer should be between somewhere ...

Calculus
I am unsure of how to take the derivative of this equation. It may be the exponents that are giving me trouble but I'm not sure exactly. Find the equation of the tangent line to the curve 4e^xy = 2x + y at point (0,4). On the left side, is the "xy" the exponent o...

Calculus
Find the equation of the tangent to the graph of f(x)=2x^4 (to the power of 4) that has slope 1. Derivative is 8 x^3. This equals 1 at x = 1/2. At this point the y-coordinate is f(1/2) = 1/8. The equation of the tangent line is thus: 1/8 + 1*(x-1/2) = x - 3/8 Thank you for you...
