This IS grammatically correct, but it sounds weird (no offense :P). It means "I would rather put on make-up than he would", more or less. There would be better-sounding ways to say this although it is correct.

math
The application of one function followed by the application of a second function to the result of the first as in F^-1(f(x)) is called composition of functions. The two functions need not be inverse of each other. In a diagram, the output of one function is f(x) is used as the...

The launching speed of a certain projectile is 3.0 times the speed it has at its maximum height. Calculate the elevation angle at launching

Chemistry
Thank you so much for the detailed steps. Finally understood what I need to do.

Chemistry
Calculate the value of Kp for the equation C(s)+CO2(g)<->2CO(g) Kp=? given that at a certain temperature C(s)+2H2O(g)<->CO2(g)+2H2(g) Kp1=3.33 H2(g)+CO2(g)<->H2O(g)+CO(g) Kp2=.733 Please show detailed steps.

A stone is aimed at a cliff of height h with an initial speed of v = 64.0 m/s directed 55.0° above the horizontal, as shown in the Figure below by the arrow. The stone strikes at A, 7.31 s after launching. What is the height of the cliff? What is the maximum height H reach...
