Answer: A: V is an acute angle, so it is less than 90 degrees. I would say it's around 45 degrees.
B: K is also an acute angle, but it is fairly close to being 90 degrees, so I'd say around 80 degrees.
C: Q is an obtuse angle, so it is over 90 degrees but less than 180 degrees. I would say it's around 110 degrees.
D: Y is an obtuse angle. It is very close to 180 degrees. I would say it's around 160 degrees.

Answer:
sqrt(1/2x+6) = h^-1 (x)
Step-by-step explanation:
To find the inverse, we exchange x and y and then solve for y
y = 2x^2 -12
Exchange x and y
x = 2y^2 -12
Solve of y
Add 12 to each side
x+12 = 2y^2
Divide by 2
(x+12) /2 = 2y^2/2
(x+12)/2 =y^2
1/2 x+6 = y^2
Take the square root of each side
sqrt(1/2x+6) = sqrt(y^2)
sqrt(1/2x+6) = y
This is the inverse
Answer:
B.
Step-by-step explanation:
there cannot be two of the same x value's. It would make it a circle on the graph, or something close to that, which isn't a function.
