The formula is used to calculate acceleration as the change in velocity over the period of time. Solve the formula for the final velocity, vf, in terms of initial velocity, vi, acceleration, a, and time, t.

Complete the equation:

vf=

use vi for vi

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.
