Answer:
The correct option is A.
Step-by-step explanation:
The correct form is:
4sin^2 x − 1 = 0
First step is add 1 to both sides:
4sin^2 x-1+1=0+1
4sin^2 x=1
Now to eliminate 4 divide both sides by 4
4sin^2 x/4=1/4
sin^2 x=1/4
Take square root at both sides
√sin^2 x = √1/4
sinx = 1/2
Thus the correct option is 30° ....
Step-by-step explanation:
step 1. x intercepts are where y = 0
step 2. y = 0 when factors are equal to zero
step 3. the x intercepts are 0, sqr(3), -sqrt(3), -1/5
step 4. answer: 4.
