What equation can I use to find the side of a cube whose area is 729?
Answers
#2 The formula is
Substitute 729 in V since that is the volume.
Take the cube root and you will get 9.
So the formula is

Answer:
x= -5
Step-by-step explanation:
just graphed it . y = 4 is a flat horizontal line.
x=5 is a vertical line that passes through (5,2)
Final answer:
The equation of the perpendicular line is x = 5.
Explanation:
To find the equation of a line perpendicular to y = 4 that passes through the point (5, 2), we need to determine the slope of the original line. The equation y = 4 represents a horizontal line with a slope of 0. Perpendicular lines have slopes that are negative reciprocals of each other. The negative reciprocal of 0 is undefined, so the equation of the perpendicular line will be x = 5.

The graph y=x^2 is very basic so I suppose you know how it looks like.
It's like a U and starts from the origin (0,0)
The graph y=cosx is similar to y=x^2 but in a different way.
y=cosx doesn't pass from (0,0) it passes from (0,1) and then to (-1,0) and (1,0).
Basically, it goes like this..

If you know how the two graphs look like then you can understand why they intercept only two times.

c ^ 2 = a ^ 2 + b ^ 2 - 2 * a * b * cos (C)
Substituting values we have:
c ^ 2 = 10 ^ 2 + 8 ^ 2 - 2 * 10 * 8 * cos (105)
Clearing c we have:
c = root (10 ^ 2 + 8 ^ 2 - 2 * 10 * 8 * cos (105))
c = 14.33216827
