According to statistical mechanics, the average speed of molecules in an ideal gas is given by v¯ = 4 √ π m 2rt 3 2 z [infinity] 0 v 3 e −m v2/(2rt) dv, where m is the molecular weight of the gas, r is the gas constant, t is the gas temperature, and v is the molecular speed. by evaluating the improper integral, show that v¯ = r 8rt πm . to make algebra simpler, it is suggested to let m/(2rt) ≡ a and carry out the integral.

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
