to sea level
Mathematics
1 answer:
abruzzese [7]3 years ago
6 0

Answer:

-75 m

Step-by-step explanation:

Use sea level as the reference point.  

Initially the position is -50 m.

If the submarine goes up 15 m, then its new position is (-50 + 15) m, or -35 m.

If the sub now descends 40 m, its new position is (-35 - 40) m, or -75 m

Prove:<br> sin^2x (sec^2x + csc^2x)=sec^2x
Vikki [24]
Sin^2x (sec^2x + csc^2x) = sec^2x

I would convert the functions in the parentheses to their reciprocals.

sin^2x (1/cos^2x + 1/sin^2x) = sec^2x

Now distribute the sine.

sin^2x/cos^2x + sin^2x/sin^2x = sec^2x

Remember that sine divided by cosine is always tangent.

tan^2x + sin^2x/sin^2x = sec^2x

The remaining fraction is simply 1.

tan^2x + 1 = sec^2x

Use the Pythagorean identity to add the left side.

sec^2x = sec^2x
