The problem ask to calculate and find the value of cos(2npi). So base on the data you have given, we must follow the theories and rule of simplifying and calculating trigonometric expression, so base on that, the answer would be that the cos(2pi) is equals to 1 so the cos(2npi) if even =1 if odd =-1. I hope you are satisfied with my answer and feel free to ask for more
Answer:
Step-by-step explanation:
First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression 
. Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, .
Answer:
$135461.73
Step-by-step explanation:
140374.85 decrease 3.5% =
140374.85 × (1 - 3.5%) = 140374.85 × (1 - 0.035) = 135461.73025
