Answer:
a(6) = 37.97
Step-by-step explanation:
If the first term a(1) is 5 and the common ratio r is 3/2, then the general formula for this geometric sequence is
a(n) = 5*r^(n - 1).
Thus, the 6th term is a(6) = 5*(3/2)^(6 - 1), or a(6) = 5(3/2)^5 = 37.97
Answer: M∠2 just mean measure of angle 2,
Step-by-step explanation: So I worked it out and the awnser is B.
3 numbers/the degrees of all 3 sides always add up to 180 degrees.
Side 1 is 60 degrees and the left side is 20, so 20 + 60 + 3 (unkown number) = 180
60 - 20 = 100,
first number and second number and third number = Total
78 possibilities x 78 possibilities x 78 possibilities = 234
Since "order" matters, this is a permutation.
So, this can be calculated using: ₇₈P₃
"Permutation lock" would be a more appropriate name.
