Total power generated by wind worldwide doubles every 3 years. in a particular year, the world wind-generating capacity was about 95 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

This is a problem of doubling time, the general formula for doubling time is

N = A(2)^( t /d)
where N is the future wind generating capacity in thousand MW
A is the initial wind generating capacity which is 95,000 MW
d is the time it will double, which is 3 years
t is the time in the future in years

N = 95(2)^( t / 3) is the formula for 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
