Carbon-14 is an element that loses about 10% of its mass every millennium (i. e., 1000 years). a sample of carbon-14 has 600 grams. write a function that gives the sample’s mass in grams, s(t), t millennia from today.

The function that gives the sample's mass after t millennia can be derived

from the equation for decreasing rate formula.

Reasons:

The rate at which carbon-14 loses its mass = 10% per millennium

The initial mass of the sample of carbon-14 = 600 grams

Required:

A function that gives the mass of the sample in grams S(t), in t millennia

from today.

Solution:

The formula for decreasing rate is; y = a·(1 - r)ˣ

Where:

y = S(t) = The mass of the sample after t millennia

x = t = The number of millennia

a = Initial mass = 600 grams

r = The decay rate = 10% = 0.1

By plugging in the above values, we get;

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
