The graph shows the solution to a system of inequalities: Solid line joining ordered pairs 0, 3 and 7, 0. Shade the portion of the graph below the line in the first and fourth quadrants. Which of the following inequalities is modeled by the graph? 2x + 5y ≥ 14; x ≥ 0 2x + 5y ≤ 14; x ≥ 0 2x − 5y ≤ 14; x ≥ 0 −2x − 5y ≤ 14; x ≥ 0

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:
