Answer:
B. cos(ln(2x))/x
Step-by-step explanation:
We know that the inverse of sin is cosine. Note, arcsin means the same thing as inverse sin:
Because sin (a) = sin (b) --> a = arcsin (b)
- Therefore: ln(2x) = arcsin(y)
- Solve ln(2x)=arcsin(y) for x
- (e^arcsin(y))/2
Subsitute y = x
- (e^arcsin(x))/2
- Therefore, we get the answer as cos(ln(2x))/x
Answer:
s = 17
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan60° = , then
tan60° = = = ( multiply both sides by s )
s × = 17 ( divide both sides by )
s = 17
The answer is 110. (Brainly isn't letting me use 'enter', I don't know why) Basically you can cross multiply to get 990 = 9x. Divide both sides by 9 to get 110. Or you can just scale up by multiplying the fraction on the left side by 10/10 to get 90/110. I hope I helped! If it did, feel free to give me a 'brainliest answer'.
