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

46.2+112.3

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
