Answer:
equation ( 1.25x = 27.5 ) and x = 22.
Step-by-step explanation:
Shampoo bottle contains shampoo = ounces = 30.5 ounces
If 3 ounces spilled out the remaining amount of shampoo = ( 30.5 - 3 ) = 27.5 ounces.
Every time he shampoos his dog, amount of shampoo required = ounces = 1.25 ounce
If x is the number of times Nico can bathe his dog using the same bottle of shampoo then total amount used = (1.25) (x) ounces
Now remaining amount of shampoo = ttal amount used to shampoo the dog
(27.5) = (1.25x)
x= = 22 times
So answer will be equation ( 1.25x = 27.5 ) and x = 22.

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.
