Plz a radioactive element decays exponentially at a rate of 0.13% each hour. which of the following is true? - there will be slightly more radioactive element in 24 hours. - the amount of radioactive element will continue to grow infinitely large. - if there are 1,000 grams of the element, there will be 756.9 grams in two hours. - the amount of the element will decrease closer and closer to zero as time goes on.

D would be the only answer that makes sense I’m not 100%

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
