If population PPP changes with time ttt, which derivative represents its growth rate?
A
The order of a differential equation is determined by its highest derivative.
B
For dPdt=kP(5000−P)\frac{dP}{dt}=kP(5000-P)dtdP=kP(5000−P), growth is zero at P=0P=0P=0 or P=5000P=5000P=5000.
C
dPdt\frac{dP}{dt}dtdP
D
d2sdt2=−ks\frac{d^2s}{dt^2}=-ksdt2d2s=−ks
