Answer:

  (a)  (-12/13, 5/13)

  (b)  (12/13, -5/13)

  (c)  (-12/13, -5/13)

  (d)  (12/13, 5/13)

Step-by-step explanation:

(a) The terminal point is effectively reflected across the y-axis, so the sign of the x-coordinate changes. (-12/13, 5/13)

__

(b) The terminal point is effectively reflected across the x-axis, so the sign of the y-coordinate changes. (12/13, -5/13)

__

(c) The terminal point is effectively reflected across the origin, so the signs of both coordinates change. (-12/13, -5/13)

__

(d) The terminal point is mapped to itself, so its coordinates remain unchanged. (12/13, 5/13)

Answer:

50 J

Step-by-step explanation:

According to energy conservative law energy can not be destroyed. So as the potential energy has been decreased to 50 J, the decreased amount has become kinetic energy.

Where can u place these at tell me
Alex777 [14]
The best thing to do is to rewrite the fractions as decimals
-2/3 is approx. equal to -0.6666667
So a little past half way (to the left) between -1 and 0
1 1/5 is 1.5 so that is right between 1 and 2

Hope this helps :)

What is 2/50 as a decimal
Thepotemich [5.8K]
Okay so what we need to do is simplify 2/50, which is 1/25.
Now divide 25 into 1.
Which we will get 0.04
Now we need to move the decimal 2 times to the right.
It will be 4%
Or just multiply it by 100 and you will get 4%.
