Remember that squaring something is just multiplying that number by itself.
Answer:
The inverse of the h(x) is Step-by-step explanation:
Given : Expression
To find : The inverse of the expression ?
Solution :
Expression
Let, h(x)=y then
For inverse we replace the value of x and y and find the value of y in terms of x.
Replace the value of x and y,
Solve for y by cross multiply,
Adding 4 both side,
Dividing by 2 both side,
Therefore, The inverse of the h(x) is
The length of the support post is 40 ft.
<u>Solution:</u>
Given, the height of the wall is 20 ft; support post forms 30 degree
Refer the attached image
Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and is 30 degree (
) and AC is the length of the post.
To find: The length of the post (AC)
we know the formula, (trigonometric formula)
On substituting the values we get,
The value of sin 30 degree is 0.5
