Answer:
Yes, it is a proportional relationship!
Step-by-step explanation:
10 to the second power=100
74.75/100= .7475
Yes, it does. Because these points do respect the "law" that for each "x" there is only one "y" that corresponds to it
Answer:
t= 24.75 days
Step-by-step explanation:
Here A(t) is the amount of the element that remains after some time. So they tell us that find the time it takes to basically have 4 grams remaining so A(t) = 4
4 = 10 * 0.5 ^ (t/18.72)
0.4= 0.5 ^ (t/18.72)
t= 24.75 days
Answer should make sense because half life is around 18 days which means to go from 10 g to 5g would be somewhere around 18 days but we are going to 4 g so it takes more days
