Hi guys whats 3.5-4.7-5.50+67.9=

The ratio pv to nrt is plotted against pressure for ch4 at 0°c and 200°c. why does the curve for 0°c drop below the horizontal line for an ideal gas whereas the curve for 200°c does not?

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
