Consider a population P = P(t) with constant relative birth and death rates α and β, respectively, and a constant emigration rate m, where α, β, and m are positive constants. Assume that α > β. Then the rate of change of the population at time t is modeled by the differential equation: dP/dt = kP - m where k = α - β(a) Find the solution of this equation that satisfies the initial condition P(0) = P0. (Write an equation involving P, P0, k, m, and t.).

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

the square root of what number? if you add that, then someone will probably answer the question.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

make sure you have version 2.50

try looking in the very back of the book : )
