Answer:

It is complicated to answer but there are several factors which contribute toward the difficulty of learning how to solve problems. A person's motivation (anxiety) and poor understanding of the how and why of the material. But there are more internal factors as well, mental and metal learning handicaps. For example, Dyscalculia is a common condition where individuals have issues with making basic calculations and using those numbers the way their peers do. (Dyslexia, ADD/ADHAD, Dysgraphia, and Dyspraxia are other examples.

What is the equation for g, which is f(x) = 2x2 + 3x − 1 reflected across the y-axis? Group of answer choices g(x) = −2x2 − 3x −

Sergio [31]

Answer:

$g(x) = 2x^2 - 3x - 1$

Step-by-step explanation:

Given

$f(x) = 2x^2 + 3x - 1$

Required

Determine g(x), if f(x) is reflected across the y axis

When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).

In other words,

$g(x) = f(-x)$

Calculating f(-x)

$f(-x) = 2(-x)^2 + 3(-x) - 1$

$f(-x) = 2x^2 - 3x - 1$

Substitute g(x) for f(-x)

$g(x) = 2x^2 - 3x - 1$

Hence;

$g(x) = 2x^2 - 3x - 1$

What is the hydronium ion (H3O+) concentration in milk if it has a pH of 8.2?

valkas [14]

The hydronium ion is H₃O⁺ and its concentration is equivalent to the H⁺ ion concentration. The H⁺ ion concentration is given by:

pH = -log[H⁺]
[H⁺] = 10^(-8.2)
[H⁺] = 6.31 x 10⁻⁹ mole/dm³

The hydronium ion concentration is 6.31 x 10⁻⁹ mole/dm³
