<u>Answer:</u>
The correct answer option for this is: False.
<u>Step-by-step explanation:</u>
We are given the following statement which we are to determine whether its true or false:
<em>In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.</em>
To form a negation, we add the word 'not' to a statement - this part of the given sentence is true.
While 'or take "not" out of a statement if it already exists' is false which makes the whole sentence false.
Answer:
d. -7/25
Step-by-step explanation:
π<θ<3π/2 in third quadrant
tanθ = 4/3
sinθ = - 4/5
cosθ = - 3/5
cos 2θ = cos²θ - sin²θ = (- 3/5)² - (- 4/5)² = 9/25 - 16/25 = - 7/25
Answer with Explanation:
If a polygon has symmetry, then it has reflective portion over the line of symmetry.
Note that a rectangle doesn't have the diagonal lines of symmetry since its portion doesn't overlap another.
The simplest symmetry is Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry). It is easy to see, because one half is the reflection of the other half.
I hope it will help you.
Here is the solution for the eqns.
