How does radioactive decay relate to precalculus?
it is a natural example of the exponential function
What general pattern is found on a graph of radioactive decay?
A deacresing exponential graph is formed.
What are the real life examples of exponential functions?
Compound interest, depreciation, bacterial growth, radioactive decay etc.
In chemistry what is a half life?
The half-life of a quantity whose value decreases with time is the interval required for the quantity to decay to half of its initial value. The concept originated in describing how long it takes atoms to undergo radioactive decay but also applies in a wide variety of other situations.Half-lives are very often used to describe quantities undergoing exponential decay-for example radioactive decay-where the half-life is constant over the whole life of the decay, and is a characteristic unit (a natural unit of scale) for the exponential decay equation. However, a half-life can also be defined for non-exponential decay processes, although in these cases the half-life varies throughout the decay process. The converse for exponential growth is the doubling time.
What is the source of heat in the Earth's interior?
The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.
Do all exponential functions show growth over time?
If the exponent has the variable of time in it, then it will be either exponential growth (such as compound interest for example), or exponential decay (such as radioactive materials, or a capacitor discharging). If the time constant (coefficient of the time variable) is positive then it is growth, if the time constant is negative, then it is decay.

Sample problem for exponential decay?
A common example of exponential decay is radioactive decay. Radioactive materials, and some other substances, decompose according to a formula for exponential decay.That is, the amount of radioactive material A present at time t is given by the formulaA=A0ektwhere k < 0.A radioactive substance is often described in terms of its half-life, which is the time required for half the material to decompose.
What is an exponential decay patter?
Many real world phenomena can be modeled by functions that describe how things decay as time passes. Examples of such phenomena include the studies of populations, bacteria, the AIDS virus, radioactive substances, electricity, temperatures and credit payments.Any quantity decays by a fixed percent at regular intervals is the exponential decay.
Categorize the graph as linear increasing linear decreasing exponential growth or exponential decay.?
Exponential Decay. hope this will help :)
What is the difference between exponential growth and decay?
Exponential growth is when the amount of something is increasing, and exponential decay is when the amount of something is decreasing.
Radioactive decay do not involve electrons?
Radioactive decay may or may not involve electrons. There are different types of radioactive decay.
