Solve the quadratic equation numerically (using tables of x- and y-values). –42 - 2 + 12 a. X= 6 or x = 2 c. X = -6 or x = -2 b. x = 6 or x = -2 d. X = 6 or x = -1​

b. t=-25h+3

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:
