Problem about exponential decay.
Problem about exponential decay.
A. construct a model to represent the atmospheric pressure at a given altitude in thousands of meters? B. How many atmospheres of pressure will you feel at 5,895 meters? (Top of Mt. Kilimanjaro) C...
The sales, S, of a product have declined in recent years. 1.8 million were sold in 2009 but only 1.2 million sold in 2012. Assume the sales are decreasing according to the exponential model S(t)=Soe^kt A...
I need use this formula to find when the population will reach 7 billion
Carbon 14 is used for carbon dating. Carbon 14 decays at a rate of y=Yoe-(ln2)(1/5700)t. If a mummy is found and has exactly 1/3 of its carbon 14 remaining, how long has the mummy been entombed....
A population grows exponentially at an annual rate given by r=0.03. What will the population be in 75 years if the initial population is 2500?
half life of m-50 is 8 hrs, and you have 50 grams. "A" is number of hrs after recording and f(A) is the amt left. describe this with an exponential model. I have:...
no additional details
1) Explain when a function in the form y=a•b^x models exponential growth and when it models exponential decay.
A.) y=3^x-4 B.) y=2(4)^x C.) y=1/2(3)^x D.) y=6(1/3)^x First of what is a decay curve and how do you find it?
about 180 milligrams will remain active in your blood after 1 day. The amount of penicillin decreases exponentially
The radioactive isotope U-24 has a half-life of 18 minutes. If there's presently 150kg of U-24: determine the amount present after 54 minutes and after 2 hours. when will the amount present be less...
A population numbers 12,000 organisms initially and decreases by 6.4% each year. A) Suppose P represents the population and t the number of years of decline. An exponential...
i dont understand how to get the final answer when i find the value of .
When doctors prescribe medication, they have to consider the rate at which the body filters a drug from the bloodstream. Suppose it takes the human body 6 days filter out half of the Flu-B-Gone vaccine...
Please let me know if this expoinential function is correct for this story problem, y = 100 (1 -.5)^x Andrew measures the amount of a very unstable substance to be 100 moles...
Andrew measure the amount of a very unstable substance to be 100 moles. The half life of this substance is 3 days (after 3 days, half is gone). This is what I have so far to solve...
