How do we express this in interval notation? x < 0 or 7 < x < 9

**Algebra**

Ok so the function is f(x)=k(x-r1)(x-r2)(x-r3) =k(x-(-5))(x-ã3)(x--ã3) Now to check this?

What is r2 and r3 stand for? Not too sure how to check this. Can you show me please I got 10 more problems like this. Thanks!

**Algebra**

f(-5)= 1^3 +5(1)^2-3(1)-15 = -12. f(sqrt3) = 1^3 +5(1)^2-3(1)-15 = -12 f(sqrt-3) = 1^3 +5(1)^2-3(1)-15 = -12 Are these correct?

**Algebra**

Great! Thanks for the help! So R= 8 and the center is (-1,5) got it! Thanks again!

**Algebra**

That is what I thought, so the standard form would be (x-(-1]^2 + (y-5)^2 = 64

**Algebra**

ok based on that I would say the radius is 8 cause 8*8 = 64 and the center is (1,5)? Or do the signs change because of the equation (x-h)^2 + (y-k)^2 = r^2 making the center (-1,5)?

**Algebra**

**Chemistry**

For one mole the ideal gas law is pV=RT , write down the exact differential dV. Would I be right to differentiate with respect to T and p separately?... V = RT/p dV = R/p - (RT)/(p^2)

**Chemistry**

In solution it would separate into ions. As this is a strong base it would be fully dissociated in solution i.e K+ ions and OH- ions.
