Hello,
We suppose x≠+/-π/2.
2cos x - √2=0
==>cos x=√2/2
==>x= π/4 or x=3π/4 (modulo 2π)
Answer:
Gandhi's nonviolent movement worked because Gandhi wanted to be treated equally like his protesters. Gandhi's nonviolence worked because when he found out about this he requested that he should be sentenced even longer than the protesters.
Answer:
m = -21
Step-by-step explanation:
9+m/3=2
1. Subtract 9 from both sides
9 - 9 + m/3 = 2 - 9
m/3 = -7
2. Multiply both sides by 3
3 (m/3) = -7 (3)
m = -21

Answer:(6,-1)
Explanation:The slope of the line can be calculated using the following formula:
slope =
We are given that:slope = -0.75
point (x1,y1) is (-2,5)
We will use each of the given points to calculate the corresponding slope, then compare the calculated slope with the given one.
For point (6,-1):slope =

= -0.75 ........> accepted choice
For point (2,8):slope =

= 0.75 ........> rejected choice
For point (-5,1):slope =

= 4/3 ........> rejected choice
For point (1,1):slope =

= -4/3 ........> rejected choice
Therefore, the first option is the only correct one.
Hope this helps :)
