Answer:
He works 75% of the year
Step-by-step explanation: 9/12 as a fraction is 75/100, so the answer is 75%
The doubling time is a characteristic unit (a natural unit of scale) for the exponential growth equation, and its converse for exponential decay is the half-life. For example, given Canada's net population growth of 0.9% in the year 2006, dividing 70 by 0.9 gives an approximate doubling time of 78 years.
Sin⁻¹ √2 = 1/√2 = 1(√2) / (√2)(√2) = √2/2
Positive becouse it goes from negative to positive.
