Hey there!!
How do we find inverses?
In versing is the just the flip-flop of the x and y.
Given equation :
...f(x) = √(2x-6)
... y = √(2x-6)
... x = √(2y-6)
Square on both sides
... x² = 2y-6
... x² + 6 = 2y
... x² + 6 / 2 = y
Inverse :
f(x) = ( x² + 6 ) / 2
( ii ) f(x) = ( x - 2 )³ + 8
... y = ( x - 2 )³ + 8
... x = ( y - 2 )³ + 8
... x - 8 = ( y - 2 )³
... cube root on both sides
... ∛( x - 8 ) = y - 2
... ∛(x - 8 ) + 2 = y
Inverse :
f(x) = ∛( x - 8 ) + 2
Hope my answer helps!!
C = 2×pi×r
72 = 2×pi×r
so r = 36/pi
DE = 30deg×36/pi
DE = (pi/6)×(36/pi) = 6cm

inconsistent
Answer:
6
Step-by-step explanation:
I'm 99% sure you know the answer to this and didn't have to resort to this website.
3-5 = -2
Subtracting negative numbers means it becomes positive.
So the gist is that your adding 4 and 2 which is 6.
