A sample of an unknown chemical element naturally loses its mass over time. The relationship between the elapsed time t, in days, since the mass of the sample was initially measured, and its mass, M(t)M(t)M(t)M, left parenthesis, t, right parenthesis, in grams, is modeled by the following function:
M(t)=900⋅(827)t
Complete the following sentence about the rate of change of the sample. Round your answer to two decimal places.
The sample loses 13\{1}{3}31start fraction, 1, divided by, 3, end fraction of its mass every
days.

i honestly dont know

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.
