What are the similarities and differences between the standard form and vertex form of a quadratic equation? when is it most appropriate to use the completing the square method to solve a quadratic equation? i have to call my teacher and answer these questions. can anyone me?

just sum

10 + 10 = 20

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:

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
