I need help with this calculus problem. If the revenue function, R(x) = (280 – 2x)(50 + x) and the cost function, C(x) = 4(4000 – 2x), find P(x). Your answer will be in quadratic form. For example, −ax 2 + bx – c

i dont understand the question? ?

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:
