In 2003, online holiday sales were $17 billion, and in 2006, they were $26 billion.

(a) find a linear function s that models these data, where x is the year.
(b) interpret the slope of the graph of s.
(c) predict when online holiday sales might reach $41 billion.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

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:
