5 OR -5 (though 5 is generally the accepted answer) 25 to the half power is the same as radical(25).
0.5 is a half.
There are pi radians in a half of a circle, or in 180 degrees.
For an exponential function: General equation of exponential decay is A(t)=A0e^-at The definition of a half-life is A(t)/A0=0.5, therefore: 0.5 = e^-at ln(0.5)=-at t= -ln(0.5)/a For exponential growth: A(t)=A0e^at Find out an expression to relate A(t) and A0 and you solve as above

A quantity is said to be subject to exponential decay if it decreases at a rate proportional to its value. The time required for the decaying quantity to fall to one half of its initial value.Radioactive decay is a good example where the half life is constant over the entire decay time.In non-exponential decay, half life is not constant.

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.

Either express the half of a mile in kilometers; or the half of a kilometer in miles. For example, 1 mile is 5280 ft = 1.609km. So you would take half of this, which is about 0.8km. You can see that this is greater than 0.5km, so half a mile is further than half a kilometer. You are converting one expression of units to their equivalent in another set of units.
