On the graph of f(x)=sinx and the interval [−2π,0), for what value of x does the graph cross the x-axis? choose all answers that apply. select all that apply: −2π −3π2 −π −π2 −π4

Step-by-step explanation:

we are given

Any function crosses x-axis when it's y-value becomes 0

so, we can set

f(x)=0

and then we can solve for x

we can use unit circle

and we get

but we need angle on [−2π,0)

so, we can put negative sign

and we get

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
