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.

Answer from: Quest

7.00 \cdot 10^{-7} m - 1\cdot 10^{-3} m

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

1 nm = 10^{-9} m\\1 mm = 10^{-3} m

let's start from the lower value, we have:

700 nm = 700 \cdot 10^{-9} m = 7.00 \cdot 10^{-7} m (we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

1 mm = 1 \cdot 10^{-3} m

so, the range of wavelength of infrared radiation is:

7.00 \cdot 10^{-7} m - 1\cdot 10^{-3} m
