Use the equation y=ae^k^t[/tex], where a represents the initial amount, t represents time and k is the rate of growth or decay. After 12 hours, half of a 16-gram sample of a radioactive element remains.

Question 1
Find the constant k for this element. (4 places)
Write the equation for modeling this element.
If 2 grams of the sample remains, how much time has passed? (nearest whole number)

Question 2
After 22 hours, 25% of a sample of a random element remains. Find the constant k for this element- and write the equation for modeling it's exponential decay.

k = (4 places)

equation
How many samples would remain after 25 hours? (1 place, use a percentage. ex. 16.4%)

() (98 points)to be fair, you have to have a very high iq to understant the jokes in rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them. and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid
