Aproportional relationship between the number of pounds of potatoes (x) and the price in dollars(y) is graphed, and the ordered pair (5,4) is on the graphed line. part a: what is the price of 1 pound of potatoes? show your work. part b: what does the ordered pair (10,8) on the graph represent? explain in words.

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

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:
