Write a story about elevation that this expression could represent: 56 + (-56)
Ostrovityanka [42]

The correct statement that represents the expression is:

  • An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0m

Given the expression 56 + (-56).

  • We can see that this is an inverse rule where a value and its negative are added together.

Let us assume the values are distance covered by an object.

The correct statement that represents the expression is:

  • An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0m

This show that  56 + (-56) = 56 - 56 = 0

Is the sqrt of 1 - sin^2 theta = cos theta true? If so, in which quadrants does angle theta terminate?
Genrish500 [490]

Answer:

Answer: The answer is option B.

Step-by-step explanation:

Here,

We have,

{ \sin }^{2}  theta \: +  {cos}^{2}theta  = 1

{cos}^{2} \: theta  = 1 -  {sin}^{2}  \: theta

cos \: theta =  \sqrt{1 -  { \sin }^{2}theta }

So, it's true; and it lies in quadrant 1 and 4.

The reason according to the "CAST" rule cos theta is in 1st and 3rd quadrant cos theta is positive.
