Answer:
-8
Step-by-step explanation:
Saying arccos(-√2/2) is the same as saying cos(x)=-√2/2. This is one the trigonometric values you should have memorized if you are taking a a trig class. In order to get √2/2, x must be equal to 45° or pi/4. But since it is a negative √2/2, the answer would be -45°or -pi/4.
There are technically multiple answers to this, but since you weren't given a range for the answers, I would stick with -45°.
Hope this helps
Answer: look up true or false for the last answer but other than that th answer should be true
Step-by-step explanation:
I've Answered a question like this in the past (though it was linear) examples of a linear table are x:1234
and then y: -3 -5 -7 -9. so for a non linear table it would have to be odd numbers x:1234
y:3 6 12 24
remember my example and dont use 1234, -3 -5 -7 -9 ok?
