Answer:
6, 3
Step-by-step explanation:
Answer:
(g•f)(x) = x.
Step-by-step explanation:
Let 
, then the inverse function of the f(x) is 
So, (g•f)(x) = ![g[f(x)] = g(x^{2} + 1 ) = \sqrt{(x^{2} + 1) - 1} = \sqrt{x^{2} } = x](https://tex.z-dn.net/?f=g%5Bf%28x%29%5D%20%3D%20g%28x%5E%7B2%7D%20%2B%201%20%29%20%3D%20%5Csqrt%7B%28x%5E%7B2%7D%20%2B%201%29%20-%201%7D%20%3D%20%5Csqrt%7Bx%5E%7B2%7D%20%7D%20%3D%20x)
Therefore, we can write if f(x) and g(x) are inverse functions of each other, then (g•f)(x) = x.
Hence, option D is correct. (Answer)
Answer:
52m
Step-by-step explanation:
rhombus
its like a slanted square
all its 4 sides are equal like a square
both pairs of opposite sides are parallel
when the diagonals criss cross they make 4 triangles inside
the sides of the rhombus become the hypotenuse of a triangles inside
if the diagonal is 24 and 10 then
its radius is 12 and 5
the sides of the rhombus become the hypotenuse of a triangle that have the sides 12 and 5
hypotenuse of a triangle that has the sides 12 and 5 is
13
(its a special triangle: its a 5, 12, 13 right triangle)
13 times 4 is 52
Step-by-step explanation:
x² + 4x + y² + 16y - 20 = 0
(x² + 4x + 4) + (y² + 16y + 64) - 4 - 64 - 20 = 0
(x + 2)² + (y + 8)² = 88.
