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.
17.2/43= 0.4
Since the scale is 1:43, you would just divide the actual length by 43.
0.4:17.2 is congruent to 1:43.
43/17.2= 2.5
1/.04= 2.5
I hope this helps!

1) Yes, it is arithmetic, the common difference is -3. To find this, subtract any number from the number after it.
32 - 35 = -3
2) yes, it is arithmetic, the common difference is -20. To find this, subtract any number from the number after it.
-23 - -3 = -20
3) yes, it is arithmetic, the common difference is -30. To find this, subtract any number from the number after it.
-64 - -34 = -30
4) yes, it is arithmetic, the common difference is -10. To find this, subtract any number from the number after it.
-40 - -30 = -10
yes, it is arithmetic, the common difference is -2. To find this, subtract any number from the number after it.
-9 - -7 = -2
yes, it is arithmetic, the common difference is 5. To find this, subtract any number from the number after it.
14 - 9 = 5
