Answer: The coefficients of binomial expansions are calculated using Pascal's triangle.
Answer:
sec x = √10 /3
Step-by-step explanation:
tanx = 1/3
tan²x = (1/3)²
= 1/9
Trigonometric identity
sec²x - tan²x = 1
sec²x = 1 + tan²x
sec²x = 1 + 1/9
= 10/9
Now, sec x = √(10/9)
= √10 / 3

For the first movie he has 6 choices, then for the second since he has chosen the first there are only 5 left, then for the third there are only 4 choices left and so on.
Therefore the answer is 6!=6*5*4*3*2=720 orderings
6.62 x 102 is the answer.
