Answer:
Step-by-step explanation:
Sn= -[-3(sin^2x + cos^2x)^n + In e.
sin^2x + cos^2x = 1 and ln e = 1, so
Sn = -(-3)^n + 1
When n = 8
this = -(-3)^8 + 1
Answer:
Step-by-step explanation:
6< 3x + 9
-3x < 9-6
-3x < 3 .( -1 )
3x > 3
x > 3/3
x > 3
3x + 9 ≤ 18
3x ≤ 18-9
3x ≤ 9
x ≤ 9/3
x ≤ 3
S = {XeIR/ 3 > x ≤ 3 }
