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 (in thousand megawatts) as a function of t, the number of years in the future.

r ≈ 26%

Step-by-step explanation:

Total power generated by wind worldwide doubles every 3 years.

In a particular year, the world wind generating capacity was 85 thousand megawatts.

So, the formula for wind generating capacity W (in thousand megawatts) as a function of t. the number of years in the future will be given by  

........ (1)

Therefore, for t = 1 year,

thousand megawatts.

Again, for t = 2 years,

thousand megawatts.

As the continuous growth rate is exponential, so, we can write

⇒

⇒ r = 25.99% ≈ 26% (Answer)
