the base of the ladder is 18ft away from the wall
The statement is true because the arcsin function is defined to be the inverse of the sin function.
<h3>
What are inverse functions?</h3>
For invertible function f(x) (this means that f(x) has an inverse) we define the inverse function g(x) such that:
f(g(x)) = x
g(f(x)) = x
Now, particularly for the sin function, arcsin is defined as the inverse function.
Then by definition, arcsin must meet the conditions:
- arcsin(sin(x)) = x
- sin(arcsin(x)) = x
So the answer is true for the definition of the arcsin function.

Step-by-step explanation:
3 yards in a ft, so 15 yards in 5 ft.
<span>A freight train completes its journey of 150 miles 1 hour earlier if its original speed is increased by 5 miles/hour. What is the train’s original speed?
***
let x=original speed
x+5=increased speed
travel time=distance/speed
..
lcd:x(x+5)
150(x+5)-150x=x(x+5)
150x+750-150x=x^2+5x
x^2+5x-750=0
(x-25)(x+30)=0
x=25
What is the train’s original speed? 25 mph</span>
The answer is 1 1/5
Hope this helps
