Answer:
2
Step-by-step explanation:
S=1+1/2+1/4+1/8+...
Multiply both sides by 2:
2S=2+1+1/2+1/4+1/8+....
Subtract equations:
-1S=-2
Divide both sides by -1
S=2
Or you could just keep adding more terms of the series to see it is approaching 2.
1+1/2=3/2=1.5
1+1/2+1/4=1.75
1+1/2+1/4+1/8=1.875
And so on..
If you have
2 KNOWN sides & 1 Angle ;
Use Cosine Rule
If you have 3 KNOWN sides,
Also Cosine Rule
If you have
2 KNOWN angles & 1 side,
Use SINE rule
If it's a right-angled triangle, use SOH CAH TOA
Hopefully this helps
Answer:
18
Step-by-step explanation:
xy + 4 = 40
xy = 40 - 4
xy = 36
What two numbers can b multiplied to give 36? Then add them.
9 + 4 = 13
18 + 2 = 20
6 + 6 = 12
12 + 3 = 15
The odd option is 18
