Total power generated by wind worldwide doubles every 3 years. in a particular year, the world wind-generating capacity was about 85 thousand megawatts. find the continuous growth rate and give a formula for wind generating capacity w w (in thousand megawatts) as a function of t t , the number of years in the future. the continuous growth rate is percent. w= w =

If there is an exponential growth rate, then FV=Pe^rt, where FV is future value, P is the initial amount, r is the growth constant, and t is time. So, the equation here is:
W(t)=W(0)e^rt, where W(0)is the initia
l rate, and t is time. In order to double:
W(3)/W(0)=2=e^3r
ln 2= ln e^3r=3r ln e=3r
r=.23104
So W(t)=85e^.23104t  where the products give the electricity produced in thousands of megawatts

How many people are we starting with? i will answer it's just i need to divide 8 by the total amount of people to get how many tables
