If HJR is 9/10 π, what is RHJ?

Step-by-step explanation:

We know that the whole length of the circumference is .

By given, we have , and by definition of central angle.

That means

Also,

Therefore, the measure of the arc RHJ is 279° which is equivalen to choice A.

true

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
