k and m are constants. the function f(x)= x2 - kx +3 intersects the function g(x) = -kx +m at the point (-1,6). what is the valu
SOVA2 [1]

Answer:

k=2 m=5

Explanation:

At the point -1,6 we know that both equations are equal to 6 so we solve x^2- kx+3=6 and we get that k=2, after this we plug k into the other equation and set it equal to 6 again and solve for m

What is the ph of a 0. 300 m solution of aniline (c₆h₅nh₂, kb = 4. 3 × 10⁻¹⁰)?.
yawa3891 [41]

The pH of the solution of aniline is; pH = 4.64

<h3>pH of aniline solution</h3>

According to the question;

  • We are required to determine the hydrogen ion concentration, pH of the given aniline solution.

Since, the given Kb is kb = 4. 3 × 10⁻¹⁰.

Hence, it follows that;

  • Ka = 10-¹⁴/4. 3 × 10⁻¹⁰.

  • Ka = 2.3 × 10⁻⁵.

On this note, the pH of aniline solution is;

  • pH = -log {2.3 × 10⁻⁵}

pH = 4.64.

Ultimately, the pH of the aniline solution given is; 4.64
