Scientists use carbon-14 dating to determine the age of a sample of organic material. a. The amount C (in grams) of a 100-gram sample of carbon-14 remaining after t years is represented by the equation C=100(0.99988)t C = 100 ( 0.99988 ) t . Use a calculator to find the amount of carbon-14 remaining after 4 years. Round your answer to the nearest hundredth. The amount of carbon-14 remaining is about grams. b. What percent of the carbon-14 remains after 4 years? Round your answer to the nearest hundredth. The percent of carbon-14 remaining is about %.

a) 99.95 grams are remaining after 4 years.

b) The percent of carbon-14 remaining is about 99.95%

Step-by-step explanation:

The amount of carbon 14 remaining after t years is given by the following equation:

a) Amount remaining after 4 years.

99.95 grams are remaining after 4 years.

b) Percentage remaining after 4 years:

The percent of carbon-14 remaining is about 99.95%

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
