A cat eats 1/2 cup of food a day. Which equation represents
how much food it eats over time?

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

something over 10 so ? /10

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:
