The diagram shows an awning on the front of a building. The top of the awning makes a 40° angle with the building. The base of t
slamgirl [31]

Answer:

Height of the awning = 9.52 feet

Step-by-step explanation:

For better understanding of the solution, see the attached diagram of the problem :

According to the figure, AB is the height of the awning

Now, the base of awning will be perpendicular to the building

⇒ m∠ABC = 90°

In ΔABC, By using angle sum property of a triangle

m∠ABC + m∠ACB + m∠BAC = 180°

⇒ m∠ACB = 50°

Now,\tan 50=\frac{Perpendicular}{Base}\\\\tan 50=\frac{AB}{8}\\\\\implies AB=8\times \tan 50\\\\\bf\implies AB=9.52 \textbf{ feet}

Hence, Height of the awning = 9.52 feet

A certain function h(x) contains the point (8,-2). Find the value of h^-1(-2) . Explain your answer.
pychu [463]

Given:

A certain function h(x) contains the point (8,-2).

To find:

The value of h^{-1}(-2).

Solution:

If a function is defined as

f(x)=\{(a,b):a\in R,b\in R\}

Then, its inverse is defined as

f^{-1}(x)=\{(b,a):a\in R,b\in R\}

It is given that, a certain function h(x) contains the point (8,-2). It means, its inverse h^{-1}(x) contains the point (-2,8). So, the value of inverse function is 8 at x=-2, i.e.,

h^{-1}(-2)=8

Therefore, the value of h^{-1}(-2) is 8.
