Do you have a protractor? You’ll need one measure the angles.

Answer:

∠x and ∠y are a pair CORRESPONDING ANGLES.

Step-by-step explanation:

Corresponding Angles: The angles formed on a same side of traversal when it passes through two parallel lines is called corresponding angles.

Corresponding angles are non- adjacent in nature

Also they are congruent to each other as they lie between the same parallel lines.

Here, ∠x and ∠y are a pair of CORRESPONDING ANGLES.

Which expression is equivalent to the following complex fraction?

True [87]

Answer:

Step-by-step explanation:

Given the complex fraction;

$-\frac{2}{x} +\frac{5}{y} / \frac{3}{y} - \frac{2}{x} \\$

First we will find the LCM of the numerator and the denominator as shown below;

$\frac{-2y+5x}{xy} /\frac{3x-2y}{xy}$

Then we divide both equation by multiplying the numerator by the reciprocal of the denominator as shown;

$= \frac{-2y+5x}{xy} * \frac{xy}{3x-2y} \\= \frac{-2y+5x}{3x-2y} \\$

This gives the required answer

Which are characteristics of table salt (NaCl)?

oee [108]

Answer:

The correct option (c) "is held together by ionic bonds".

Step-by-step explanation:

Table salt is NaCl. It is a combination of Sodium and Chlorine.

There is 1 valance electron in sodium. Its electronic configuration is 2,8,1

The electronic configuration of Chlorine is 2,8,7. It means that it needs 1 electron so that its octet gets completed.

Na transfers one electron to Cl. It becomes Na⁺. Cl gains one electron From Na. It becomes Cl⁻.

As a resuslt, Na⁺ and Cl⁻ forms. Both Na and Cl are ions. They held together by ionic bonds.

Use lagrange multiplier techniques to find the local extreme values of f(x, y) = x2 − y2 − 2 subject to the constraint x2 + y2 =

dexar [7]

Given $f(x,\ y)=x^2-y^2-2$ subject to the constraint $x^2+y^2=16$

Let $g(x,\ y)=x^2+y^2$ .

The gradient vectors of $f$ and $g$ are:

$\nabla f(x,\ y)=\langle2x,-2y\rangle$ and $\nabla g(x,\ y)=\langle2x,2y\rangle$

By Lagrange's theorem, there is a number $\lambda$ , such that

$\langle2x,-2y\rangle=\lambda\langle2x,2y\rangle=\langle2\lambda x,2\lambda y\rangle$

$\lambda=\pm1$

It can be seen that $f(x,\ y)=x^2-y^2-2$ has local extreme values at the given region.
