What is the solution of the system of equations? ⎧ ⎪ ⎨ ⎪ ⎩ 3 x + 2 y + z = 7 5 x + 5 y + 4 z = 3 3 x + 2 y + 3 z = 1

98%

step-by-step explanation:

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:

2: 10
