What is the pH of a solution with [H3O+] = 1 x 10-9 M? My answer is pH=9. is that correct

how does thederivative of -2xcos(x^2)= -4xcos(x^2) -2sin(x^2) and not -4x^2cos(x^2) -2sin(x^2)?

How does 0-(1/81)-((te^9t)/81)+(9e^9t/81)=(-1/81)-0+0? Where does the 0 come from?

Go stick it up ur booty

cos(4) is same asarccos(1/4). In which 1 is the adjecent and 4 is the hypatanu. the √(4^2-1^2)= √15

Can you show more steps

I don't know did I follow your steps correctly but I think this is how you did it, right? (n^2)/√ (n^3+ 9n) = n^2 / √(((n^3)/(n^3))+(9n/n^3)) =n^2 / √((1+9/n^2)) = n^2 / √(1) =n^2 =∞ or diverges Thank you

The graph is help but I need to learn the steps for the test.

Its actually bubble guppies thank you very much

... is correct thank you
