Consider the equation 1/4(x - 5) = (y – 2)^2. What is the equation of the directrix? x = 4.0000
x = 4.7500
x = 4.6250
x = 4.9375

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:

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

(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:

so, the range of wavelength of infrared radiation is:
