Answer:
The correct option is;
y = arcsinx and y = arctanx
Step-by-step explanation:
The given options are;
1) y = arcsinx and y = arccosx
Here, we have at the origin, where x = 0, arccosx ≈ 1.57 while arcsinx = 0
Therefore arccosx does not intersect arcsinx at the origin for it to be symmetrical to arcsinx or the origin
2) y = arccosxy and y = arctanx
Here arctanx = 0 when x = 0 and arcos x = 1.57 when x = 0 therefore, they are not symmetrical
3) y = arctanx and y = arccotx
Similarly, At x = 0, arccotx = 1.57 therefore, they are not symmetrical
4) y = arcsinx and y = arctanx
Both functions arcsinx and arctanx pass through the origin and their shapes are similar but inverted as they go from negative to positive.

Answer:
Option 3: 2/(x-4)
Step-by-step explanation:
Factoring the top part:
2x + 8 = 2(x+4)
Factoring the bottom part using difference of squares:
x^2 - 16 = (x+4)(x-4)
We can cancel the x+4 from the top and the bottom, so all we are left is:
2/(x-4)
Answer: $282.88
Step-by-step explanation: $3.45 times 24 is $282.88
Answer:
x = 3
Step-by-step explanation:
5x - 2 = 3x + 4
2x = 6
x = 3
