Answer:
a) 
b) Wind capacity will pass 600 gigawatts during the year 2018
Step-by-step explanation:
The world wind energy generating capacity can be modeled by the following function

In which W(t) is the wind energy generating capacity in t years after 2014, W(0) is the capacity in 2014 and r is the growth rate, as a decimal.
371 gigawatts by the end of 2014 and has been increasing at a continuous rate of approximately 16.8%.
This means that

(a) Give a formula for W , in gigawatts, as a function of time, t , in years since the end of 2014 . W= gigawatts



(b) When is wind capacity predicted to pass 600 gigawatts? Wind capacity will pass 600 gigawatts during the year?
This is t years after the end of 2014, in which t found when W(t) = 600. So




We have that:

So we apply log to both sides of the equality





It will happen 3.1 years after the end of 2014, so during the year of 2018.
Answer: $5,744.61
Step-by-step explanation:
year 1 = -2,277
year 2 = -2026.53
year 3 = -1803.61
year 4 = -1605.21
year 5 = -1428.64
year 6 = -1271.49
year 7 = -1131.62
year 8 = -1007.17
year 9 = -896.36
year 10 = -797.76
year 11 = -710
you are subtracting 11% from each year.
