Answer:
The inverse f-1(x) = ( x - 2) / 2.
Step-by-step explanation:
Let 2x + 1 = y
Now find x in terms of y:
2x = y - 1
x = (y - 1) / 2
Replace the x by the inverse f-1(x) and the y by x, so we have:
f-1(x) = ( x - 2) / 2.
Answer:
Step-by-step explanation:
you add two angles and then subtract it from 180 degrees
Hopefully it is right
for example: A angle+B angle-180 degrees
Answer:
Blank 1: opposite
Blank 2: adjacent
Blank 3: opposite
Blank 4: adjacent
Step-by-step explanation:
There is a trigonometric acronym for this which is:
Soh Cah Toa
Soh means that sine is opposite over hypotenuse.
Cah means that cosine is adjacent over hypotenuse.
Toa means that tangent is opposite over adjacent.
Let me actually write these out as fractions:
sine is 
cosine is 
tangent is 
Blank 1: opposite
Blank 2: adjacent
Blank 3: opposite
Blank 4: adjacent
Answer:
the right answer is 2 < s< 18
Step-by-step explanation:
The Third side of the triangle must be greater than the difference of the other two sides which is 10 -8= 2 and smaller than the sum of the other two sides of the triangle which is 10+8= 18.
so third side should be greater than 2 and less than 18.
So right answer is 2 < s< 18
