3, 9, 27, 81, 343, 729, … is a geometric sequence because each term is obtained by multiplying 3 to the preceding term.
Answer:
b. -36/77
Step-by-step explanation:
As 0 < x <
/2 => tan x > 0
As 0< y <
/2 => tan y > 0
We have the formula:
As tan x = 1/(cotx) => 
As tan x > 0 => tan x = 8/15
As tan y > 0 => tan y = 4/3
As tan (x-y)=
It equals 99. 4 times 9 equals 36. 11 times 9 equals 99.
Answer:
A, x>3
Step-by-step explanation:
You solve the equation as normal by crossing out both sides and getting what equals to x, but since you divided by a negative the sign flips and you are left with your answer. Hope this helps!
