Aquantity with an initial value of 2100 decades exponentially at a rate of 0.65% every 10 days what is the value of the quantity after 186 hours to the nearest hundredth

Q(186)  = 2089.463                    

Step-by-step explanation:

Formula for decaying exponentially:

Q(t) = Q_0 e^{-rt}

where, Q(t)= quantity at time t

Q_0 = initial quantity value (2100)

t = time (186 hours)

r = rate of decaying (0.65)

r = 0.65% = 10 days

1 day =

1 hour =

186 hours =

rt = 0.00503

Q(186) = 2100*e^{-0.00503}

          = 2089.46

anser is a

step-by-step explanation:

negitive slope
