Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2
Since cosa=adjacent side / hypotenuse
cos45=1/√2
We can rationalize the denominator by multiplying numerator and denominator by √2
√(2)/2
or if you prefer: √(1/2)
Answer:
80

The mistake is in line 2, the parenthesis means multiplication therefore it has to be 3x
Answer:
337.406388 or 337 people
Step-by-step explanation:
To figure this out, use the compound interest (compounding number?) equation which is Amount = People(1 + rate)^time
So if you fill that out you get
A = 20,000(.96)^100
A = 20,000(0.0168703194)
A = 337.406388
