Asubmarine dives at an angle of 13 degrees to the surface of the water. the submarine travels at a speed of 720 feet per minute. about how deep is the sun after 5 minutes?

The depth of sun after 5 minutes is 809.82 feet

Solution:

A submarine dives at an angle of 13 degrees to the surface of the water

The submarine travels at a speed of 720 feet per minute

The figure is attached below

ACB is a right angled triangle

AB is the distance between surafce of water and submarine

BC is the depth of submarine

Let "x" be the depth of sun after 5 minutes

Therefore, distance between submarine and surface of water is:

Submarine dives at an angle of 13 degrees to the surface of the water

Therefore, angle A = 13 degrees

Now we have to find BC

By definition of sine,

Here, opposite = BC = x

hypotenuse = AB = 3600 feet

Thus, we get,

Thus the depth of sun after 5 minutes is 809.82 feet

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
