50 will be the answer. Because one of the angle is exterior so we need to make that angle interior by 180- angle... then we use the method of finding the third side by

Select the correct answer. Which function is the inverse of ?

Artyom0805 [142]

Answer:

B. $f^{-1}(x) = \frac{x + 3}{9}$

Step-by-step explanation:

$let \space\ y = f(x)\\\\y = 9x -3\\$

• Now make x the subject of the equation:

$9x = y + 3\\\\x = \frac{y + 3}{9} \\$

• Replace x with f⁻¹(x) and y with x:

$f^{-1}(x) = \frac{x + 3}{9}$

Silvio is an air-traffic controller who must calculate the altitude of an incoming plane. He sees the plane at an angle of eleva

Mrac [35]

Since the problem is not telling us the height of Silvio, we are going to assume it is not relevant for our calculations.
Let $h$ the altitude of the incoming plane. We know for our problem that the distance between Silvio and the tower is 3 miles, Also we know that the angle of elevation to the plane is 40°. With this information we can create a triangle as shown in the figure. We need a function that relates the angle of elevation with its opposite and adjacent sides, that function is tangent.
$tan \alpha = \frac{opposite.side}{adjacent.side}$
$tan(40)= \frac{h}{3}$
$h=3tan(40)$
$h=2.5miles$

We can conclude that we should use the trig function tangent to model this situation; also, we can conclude that the equation that describes this situation is $h=3tan(40)$ .
