A 8 gram sample of a substance that's a by-product of fireworks has a k-value of 0.101. Find the substance's half-Life, in days. Round your answer to the nearest tenth.

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:

wow ok so the answer is 1k or just k

because of combining like terms xd

$25 becasue a 10 increase would make it from 80 to 50
