<h2>Answer:</h2>

Option: B is the correct answer.

B. 36,623 feet

<h2>Step-by-step explanation:</h2>

The angle of elevation is: 55 degree

We model this problem by taking a right angled triangle such that the side opposite to the 55 degree is of length 30000 feet.

Now let us consider x denote the distance of the plane from Francesa.

i.e. x denote the hypotenuse of the right angled triangle.

Hence, in right angled triangle i.e. ΔABC we have:

$\sin 55=\dfrac{30000}{x}\\\\i.e.\\\\x=\dfrac{30000}{\sin 55}\\\\i.e.\\\\x=\dfrac{30000}{0.81915}\\\\\\i.e.\\\\\\x=36623.2376\ feet$

Round to the nearest feet we get: x=36,623 feet

Question is in picture below

klasskru [66]

Answer:

$\frac{y - 18}{x - 1} = \frac{23 - 18}{1.5 - 1} = \frac{5}{0.5} = 10 \\ y - 18 = 10(x - 1) = 10x - 10 \\ y = 10x + 18 - 10 = 10x + 8 \\ \boxed{f(x) = 10x + 8}$

<h2>A. is the right answer.</h2>

hope this helps.
