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)

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

40% off the regular price is the correct answer.
