F(x) = 4 [cos (x)]^2 - 3 = 0
4[cos(x)]^2 = 3
cos(x) = √3 / 2
That happens in the first and fourth quadrants, for the angles 30 degrees and 330 degrees.
Answer: x = 30 degrees and x = 330 degrees
Answer:
2 is the asnwer hard to explain have a good TEST!!
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
hope it will help
First no.=x
2nd no.=2x
3rd no. =2x+6
x+2x+2x+6=26
5x+6=26
5×=26-6
5x =20.......divide both sides by 5
x=4
1st no.=x=4
Answer:
9.06
Step-by-step explanation:
Answer:
The slope is 3.
Step-by-step explanation:
So we have the equation:
This is in the slope-intercept form, where:
Here, m is the slope and b is the y-intercept.
From the original equation, m is 3 and b is -2.
In other words, our slope is 3.
So, the slope of the equation is 3.
And we're done!
