Answer: k= -.5543

Explanation:

Given:

t=1

P(t)=10532


P(t)=(22000)/(1+1.2e^(-kt) ) >substitute what you know and solve for k


10532=(22000)/(1+1.2e^(-k(1)) ) >cross multiply


10532(1+1.2e^(-k))=22000} >divide both sides by 10532


1+1.2e^(-k)= 2.088872 >subtract 1 from both sides


1.2e^(-k)= 1.088872 >divide both sides by 1.2


e^(-k)= 1.74073 >take "ln" of both sides


ln (e^(-k))= ln 1.74073 >simplify

-k=.55430 >bring over negative and round

k= -.5543
