Carbon-14 is used for archaeological carbon dating. Its half-life is 5,730 years. How much of a 250g sample of carbon-14 will be left in 5,000 years? Write your answer rounded to the nearest hundredth.

136.54 grams

Step-by-step explanation:

-This is an exponential decay problem of a radioactive element of the form:

#Given the initial size is 250g, and the half life is 5730 years, size after 5000 yrs can be calculated as:

Hence, the size of the element after 5000 days is 136.54 grams

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
