Which equation represents a line perpendicular to the line whose equation is y = - 3x +2

y = 1/3x + 2

Step-by-step explanation:

Calculate the slope for perpedicular lines

-3 × -1 = 3, 3 ⁻¹ = 1/3

Add to equation

y = 1/3x + 2

the answer is c. 23/3

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:
