Answer:
A, B, E, and F
Step-by-step explanation:
sinx and cosx are defined for all values of x. So, sin⁻¹x and cos⁻¹x are also defined for all values of x.
A and E are correct.
tanx is defined for all values of x.
However, tan(nπ) = 0 at when n is an integer. So, tan⁻¹(±nx) is undefined. However, tan⁻¹(-½x) is defined, because -½ is not an integer.
B and F are correct.
C and D are <em>wrong</em>. Both sec⁻¹x and csc⁻¹x are undefined when -1 < x < 1, and -½ is in this forbidden region.
A scalene triangle contains three unequal in length sides. Therefore, a right scalene triangle can be constructed without the use of a ruler or compass. The 90-degree angle can be signified by a small box in the corner of the triangle that measures 90 degrees.
Answer:
2
Step-by-step explanation:
5(2)+2=12
(2)+4=6
5x+2 is twice the length of x+4. Therefore the answer is 2
Simplify -8+6(x-2)+5 to 6(x-2)-3
6(x-2)-3=9
Add the 3 to both sides
6(x-2)=9+3
Simplify 9+3 to 12
6(x-2)=12
Divide both sides by 6
x-2=12/6
Simplify 12/6 to 2
x-2=2
Add 2 to both sides
x=2+2
Simplify 2+2 to 4
x=4
I hope that is what you were asking for. :D
