1. $2.78
2. If it’s 20% off you save 13.90 so 69.50- 13.90 is $55.60
Answer:
C. Same is not an orange belt and Kate is not a red belt.
Step-by-step explanation:
A negation is an operation that "takes a statement and changes it to a statement whose true or false value is opposite". For example, if I were to say 2 + 2 = 4, the negation would be that 2 + 2 ≠ 4.
So, if Sam is an orange belt and Kate is a red belt, the negation is C. Same is not an orange belt and Kate is not a red belt.
Hope this helps!
The cosine repeats itself every 360 degrees, and it mirrors at 0 and 180 degrees. It inverts around 90 and 270.
So without using a calculator, you can tell that:
cos(520)=cos(520-360)=cos(160)
cos(160) = cos(180-20) = cos(180+20) = cos(200)
cos(160) is NOT equal to cos(20), it would be -cos(20).
cos(160) = -cos(20) = -cos(-20)
So C is the only one unequal.
