moving decimal places 5 times to the left will give you an exponent of 5

1.6x10^5 has 2 sig figs (1 and 6)

comment your question if this is still unclear :))

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.
