Question 23 4 pts
A radioactive substance decays in such way that the amount of mass
remaining after t days is given by the functionm (t) = 12e-0.067t where
m(t) is measured in grams.
1. Find the mass at time t = 0.
2. How murh of the mass remains after 30 days? (Round to nearest
tenth of a gram)

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
