An unknown polynomial is added to the expression -3x^3+2x-5 and the resulting sum is 4x^3+7x^2-3. what is the unknown polynomial?

d is correct

step-by-step explanation:

answer: the correct answer is -32

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:

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
