An artifact originally had 16 grams of carbon-14 present. The decay model A = 16 e -0.000121t describes the amount of carbon-14 present after t years. Use the model to determine how many grams of carbon-14 will be present in 7367 years. The amount of carbon-14 present in 7367 years will be approximately N grams. (Round to the nearest whole number.)
Modeling Exponential Growth and Decay Madeleine Younes A wooden artifact from an archaeological dig contains 76 percent of the carbon-14 that is present in living trees. To the nearest year, about how many years old is the artifact? (HINT: The half-life of carbon-14 is 5730 years.) The artifact is approximately years old. For additional help with this problem type, access the following resources: • TEXT Read Modeling Exponential Growth and Decay • VIDEO Watch this video on modeling exponential growth...

Please answer the following questions using exponential and logarithmic models. 4) A wooden artifact from an archaeological dig contains 70 percent of the Carbon-14 that is present in living trees. To the nearest year, about how many years old is the artifact? (The half-life of Carbon-14 is 5730 years.) In years 5) A tumor is injected with 0.5 grams of Iodine-125, which has a decay rate of 1.15% per day. Write an exponential model representing the amount of Iodine-125 remaining...
9. [-14 Points] DETAILS SPRECALC7 4.6.017. This exercise uses the radioactive decay model. The half-life of radium-226 is 1600 years. Suppose we have a 28-mg sample. (a) Find a function m(t) = moz-th that models the mass remaining after t years. m(t) = (b) Find a function m(t) = moet that models the mass remaining after t years. (Round your value to six decimal places.) m(L) = (c) How much of the sample will remain after 2500 years? (Round your...
The amount of carbon 14 remaining in a sample that originally contained A grams is given by C(t) = A(0.999879)t where t is time in years. If tests on a fossilized skull reveal that 99.89% of the carbon 14 has decayed, how old, to the nearest 1,000 years, is the skull? HINT [See Example 4.] _____ yr
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.)
Please slove both, will give upvote. Find the natue of a radioactive element, which decays according to the function A) - Age where is the time in years The half life of the element is years (Round to the nearest tenth) The amount of carbon 14 present in a paint after years is given by y = y, e d . The paint contains 27% of its carbon-14. How old are the paintings? The age of the paintings is (Round...
ANSWER ALL PLEASE! Applications of Exponential Equations Many real-life situations can be modeled by an exponential growth function of the form A(t) Ao ett constant that affects the rate of growth or decay, and t represents time. Using your knowledge of writing exponential equations that you did in the beginning of this chapter, what would A or an exponential decay function of the form A(t)-A ett where k represents the represent? 1. The amount of carbon-14 present in animal bones...
