What is another way to write P2 plus L 2 plus W?
P2 + l 2 + w
Is 1 divided by w plus 18 equals 2 a linear equation?
Yes. By the way, w = -1/16
What is the correct way to abbreviate the word with in a sentence?
The way I learned to abbreviate it in school is "w/," for example, I might write a text message saying, "I'm going w/ Charlie 2 the concert."
Is there an algebraic formula for determining an angle of reflection using only the angle of the ray and the angle of the wall?
Let r be the angle of the ray, and R the angle of reflection.If the wall is flat (i.e., if its angle is 0), then we know that r + R = Pi/2.Now suppose the wall has angle w. Then rotate the diagram by -w,so that the wall is now flat again, and the angles of the ray and itsreflection are now r - w and R - w, respectively.We then have (r - w) + (R - w) = Pi/2, which should give you enoughinformation to find R.
The length of a rectangle is three times its width If the perimeter of the rectangle is 48 inches what is its area?
Width = 'W'. Length = '3W'. Perimeter = 2 (Length + W) = 2 (3W + W) = 2 (4W) = 8W = 48 W = 6 inches and Length = 18inches Area = (Length) x W = 108 sq in============================ Easier way: Width = W, Length = 3W Area = (W) x (3W) = 3W2 We showed above that W = 6 3W2 = 3 x 36 = 108 in2
