Answer:
(0,0)
Step-by-step explanation:
They intersect at point (0,0)
Option A

<em><u>Solution:</u></em>
Given that we have to rewrite with only sin x and cos x
Given is cos 3x

We know that,

Therefore,
---- eqn 1
We know that,


Substituting these values in eqn 1
-------- eqn 2
We know that,

Applying this in above eqn 2, we get



Therefore,

Option A is correct
About 68% of the people will score between 85 and 115.
The values of 85 and 115 are exactly 15 points away, or 1 standard deviation, away from the mean.
According to the empirical rule, about 68% of the values in a normal distribution are within 1 standard deviation of the mean.
5a-9
I think this is the answer I am a little unsure of what the question is.
Answer:
Option 1
Step-by-step explanation:
5(3x+2) + 2(x-7)
15x + 10 + 2x -14
15x + 2x + 10 - 14
17x - 4
