Hi!

<h3>If a = -5, <u>-a = 5</u></h3>

So our equation is...

<u>5^{-2}</u>

<h3>When you use a negative exponents, it tells you how many times to <em>divide </em>by the number. </h3>

<em><u>1 ÷ 5 ÷ 5 = 0.04</u></em>

<h2>The answer is 0.04</h2>

Hope this helps! :)

A ship at sea, the Gladstone, spots two other ships, the Norman and the Voyager, and measures the angle between them to be 48°.
ratelena [41]

Answer:

=3501 yards.

Step-by-step explanation:

The three ships form a triangle.  From the Voyager the angle between the Norman and the Gladstone=180-(55+48)=77°

Let the position of the Voyager be V that of Norman be N and that of the Gladstone be G

Then, the distance between Norman and voyager is g

g/sin G=v/ Sin V

4590/Sin 77=g/Sin 48

g=(4590 Sin 48)/Sin 77

=3500.8 yards

The distance between the Norman and the voyager= 3501 yards.

Change the polar coordinates to rectangular coordinates. (a) (3, 5π/6)
elixir [45]
Ok so given the point (r, theta)
The corresponding Cartesian point is (r*sin(theta), r* cos(theta)) you can think about this by analyzing the points on a unit circle which is a graph of a polar circle with radius 1 and angle theta
