Answer:
3.5
Step-by-step explanation:
The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log [H3O+], where [H3O+] is the hydronium ion concentration. Find the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4
We have the Logarithmic equation
pH=-log [H3O+],
We have the hydronium ion concentration = 3.2 x 10^-4
Hence,
pH = - log[3.2 × 10 ^-4]
pH = 3.4948500217
Approximately
pH = 3.5
Therefore, the pH of a certain agricultural product with the hydronium ion concentration of 3.2 x 10^-4 is 3.5
In a situation where x is a nontrivial solution, then every entry in x should not be nonzero. Therefore, it's false.
<h3>What is a nontrivial solution?</h3>
A nontrivial solution simply means a system of equation where the determinant of the coefficient is zero. When x is a nontrivial solution of Ax = 0, then at least one entry should be nonzero.
The equation x= x2u + x3v, with x2 and x3 free (and neither u nor v a multiple of the other), describes a plane through the origin. This is true. Since they're free variables, the space span has dimensions and this spans through the origin.
The equation Ax = b is homogeneous if the zero vector is a solution. Since x = 0 is a solution. Therefore, Ax = b. Hence, b = 0.
The effect of adding p to a vector is to move the vector in a direction parallel to p. It should be noted that adding p to a vector moves it in a direction that's parallel.
