The height of the Eiffel Tower is 1050 feet. From the top, the angle of depression to a soccer ball on the ground is 20 degrees.

mihalych1998 [28]

Since the angle of depression from the Eiffel tower is congruent to the angle of elevation from the soccer ball, the angle of elevation from the soccer field is 20°

Now, we can use the trigonometric function tangent to find the distance from the soccer ball to the base of the Eiffel Tower:
 $tan( \alpha )= \frac{opposite.side}{adjacent.side}$
$tan(20)= \frac{1050}{a}$
$a= \frac{1050}{tan(20)}$
$a=2884.85$

We can conclude that the distance from the soccer ball to the base of the Eiffel Tower is 2884.85 feet.

Graph the function. label the vertex and axis of symmetry f(x) = -6x^2 - 4x - 5

VMariaS [17]

Answer:

Vertex is (-1/3, -13/3)

Axis of symmetry is x = -1/3

Step-by-step explanation:

For the vertex, you need to change it into vertex form which is y = a(x - h)^2 + k

Vertex form for this equation is:

Y = -6(x + 1/3)^3 - 13/3

To find the vertex, the formula is (h,k)

So, ( -1/3, -13/3)
