Answer:
B. 1.47*10^18
Step-by-step explanation:
Given
Distance of largest start from earth in light years = 250000
1 light year = 5880000000000 miles
So,
Distance of largest star from earth in miles = 250000 * 5880000000000
= 1470000000000000000 miles
In order to convert in scientific notation, point will be moved 18 places to the left, so the number will become:
1.47* 10^18 miles
So option B is correct..
K value = natural log (.5) / half-life
half-life = natural log (.5) / k value
half-life = -.693147 / 0.1011
half-life =

I'd say the k value should be negative AND it should have units.
