The purpose of the algorithm is to enable two users to establish a secret key securely that then can be used for subsequent encryption of messages and depends on the difficulty of computing discrete logarithms for its effectiveness.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

just get this app called photo math it should be able to do those
