Evaluate mn when m=8 and n= 1/2

4

Step-by-step explanation:

you just multiply 8(m) by 1/2(n)

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

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.
