Integrate the function upper f (x comma y comma z )equals 6 zf(x, y,z)=6z over the portion of the plane x plus y plus z equals 2x+y+z=2 that lies above the square 0 less than or equals x less than or equals 10≤x≤1, 0 less than or equals y less than or equals 10≤y≤1 in the xy-plane.

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:
