Circle p is tangent to the x-axis and the y-axis. if the coordinates of the center are (r, r), find the equation of the line containing the points of tangency.

Step-by-step explanation:

we know that

The tangency point on the x-axis is  (r,0)

The tangency point on the y-axis is  (0,r)

Find the slope of the line containing the points of tangency

Remember that the equation of the line into slope intercept form is equal to

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

substitute

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
