Question Help n The radioactive element carbon-14 has a half-life of 5750 years. A scientist determined that the bones from a mastodon had lost 64.5% of their carbon-14. How old were the bones at the time they were discovered? The bones were about years old. (Round to the nearest Integer as needed.) ina
The radioactive element carbon 14 has a hall of 5750 years. A scientist determined that the bones from a mastodon had lost 70.8% of their carbon14. How old were the bones at the time they were discovered The bones were about years old (Round to the nearest Integer as needed
5.6.vQ-3 Question Help Watch the video and then solve the problem given below. A scientist determined that the bones from a mastodon had lost 75.5% of their carbon-14. How old were the bones at the time they were discovered? The bones were about years old. Round to the nearest integer as needed.)
Carbon-14 is a radioactive element with a half-life of about 5,730 years. Carbon-14 is said to decay exponentially. The decay rate is 0.000121. We start with one gram of carbon-14. We are interested in the time (years) it takes to decay carbon-14. (A) Find the value k such that P(x < k) = 0.6. (Round your answer to two decimal places.)
The amount of carbon-14 present in animal bones after t years is given by P(t) = Poe -0.00012! A bone has lost 36% of its carbon-14. How old is the bone? The bone is years old. (Round to the nearest integer as needed.)
The amount of carbon-14 present in animal bones t years after the animal's death is given by -0.000120971 P(t) = Po e How old is an ivory tusk that has lost 20% of its carbon-14? The ivory tusk is (years old. (Round to the nearest integer as needed.)
The half-life of a certain radioactive element is about 1000 years. After 3500 years, what percentage P of a sample of this element remains ? About % of the sample remains. (Round to the nearest tenth as needed.)
5.3.131 The half-life of a certain radioactive element is about 1600 years. After 2900 years, what percentage P of a sample of this element remains? About % of the sample remains (Round to the nearest tenth as needed.)
The half-life of carbon-14 is 5730 years. How long does it take for 3.6 grams of carbon-14 to be reduced to 1.3 grams of carbon-14 by radioactive decay? years (Do not round until the final answer. Then round to the nearest hundredth as needed.)
The half life for the decomposition of Carbon-14 is 5670 years. In radioactive carbon dating of a sample, a fossilized tree is found to have 22% of the Carbon-14 found in a living tree. How many years has the tree been dead?
