A population of wolves in a county is represented by the equation P(t)=80(0.98)^t, where (t) is the number of years since 1998. Predict the number of wolves in the population in the year 2008.

Question

australopithecus · Answer

remember the rule

log(x^(t)) = (t)log(x)

australopithecus · Answer

Take the log of both sides of the equation

australopithecus · Answer

to isolate the t

australopithecus · Answer

P(t)=80(0.98)^t
=
y/80 = (0.98)^t
=
log(y/80) = log(0.98^(t))
=
log(y/80) = (t)log(0.98)
=
log(y/80)/log(0.98) = t

Seriously over view the rules of logarithms you are never going to escape them if you plan on taking math in the future also they are neat

It is how we did large calculations back in the day
