Suppose j and k vary inversely, and k=3 when j=12. find k when j=18.
2
4
24
36

k = 2.

Step-by-step explanation:

j = c/k where c is a constant.

When k = 3,  j = 12 so

12 = c/3

c = 36.

So the relation is j = 36/k

When j = 18

18 = 36 / k

So 18k = 36

k = 2.

the word superfluous means unnecessary

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
