125-95=30
95-64=31
so it would be 125
Answer:
First, let's recall some usefull information:
- cot(x) = 1/tg(x) = cos(x)/sin(x)
- tan(x) = sin(x)/cos(x)
We also know that:
- cos(x - pi/2) = sin(x)
- sin(x - pi/2) = -cos(x)
Now we can use those relationships and get:
cot(x - pi/2) = cos(x - pi/2)/sin(x -pi/2) = sin(x)/-cos(x) = -tan(x)
So we have verified the identity, and explained step by step why the identity is true.
Answer: conjunction and -20<x <16 is answer.
Step-by-step explanation:
It is a conjunction because it is and statement
|x+2|<18 gives
[Since l x-a l <b means x-a lies between -b and b ]
-18<x+2<18
subtracting 2 in the whole inequality ,we get
-18-2 <x +2-2 < 18-2
-20 < x < 16
