Step-by-step explanation:
here is tha answer..hope it helps..mark me as brainliest
3.14 the perimeter is the 4 in 3.14
3 sin x = 2 ( 1 - sin² x )
3 sin x = 2 - 2 sin² x
2 sin² x + 3 sin x - 2 = 0
Substitution: t = sin x
2 t² + 3 t - 2 = 0
t 1/2 =

t 1 = 1/2
t 2 = - 2 ( this solution is not acceptable )
sin x = 1/2
Answer:
x 1 = π / 6 + 2 kπ, x 2 = 5 π / 6 + 2 k π, k ∈ Z
Answer: 4
Step-by-step explanation: You can test whether any graph is a function using the vertical line test, where you simply draw a vertical line through the graph. If you see that the vertical line comes in contact with the graph more than once at any given x-value, you know it isnt a funciton.
