I'll answer ur question but the image is blurry
Cos( 6 x ) = 1/2
6 x = 60° ⇒ x 1 = 10°
6 x = 300° ⇒ x 2 = 50°
6 x = 420° ⇒ x 3 = 70°
6 x = 660° ⇒ x 4 = 110°
x 5 = 130°, x 6 = 170°, x 7 = 190° , x 8 = 230°, x 9 = 250°,
x 10 = 290°, x 11 = 310°, x 12 = 350°
Answer: there are 12 solutions on the interval ( 0 , 2π ).
Answer:
the required ratio is 7 : 232
Step-by-step explanation:
by solving both sides we get ,
=》7 - ( 7-7 ) : 8 × 29
=》7 - 0 : 232
=》 7 : 232
it's the required ratio ,
i hope you got it .
