Answer:

C

Step-by-step explanation:

(x+2)² + (y-3)² = 3²

x² + y² + 4x - 6y + 4 + 9 - 9 = 0

x² + y² + 4x - 6y + 4 = 0

Which formula is a molecular compound? A. NaCl B. CaO C. H2O2 D. MgS
bija089 [108]

Answer: Option (C) is the correct answer.

Explanation:

When atoms which are chemically combining tend to share electrons with each other, that is, forming covalent bonds with each other then the compound formed is known as a molecular compound.

For example, H_{2}O_{2} is a molecular compound.

This is because hydrogen atom has only one electron in its valence shell and an oxygen atom needs two electrons to complete its octet.

Therefore, sharing of electrons take place between the hydrogen and oxygen atom. As a result, it is a molecular compound.

Whereas NaCl, CaO, and MgS compounds are formed due to transfer of electron from one atom to another.

Thus, we can conclude that out of the given options H_{2}O_{2} formula is a molecular compound.

Please give the right answer and show work if possible
Step2247 [10]

Answer:

14

Step-by-step explanation:

Sin(∅) = Opposite angle ÷ hypotenuse.

Sin (45) = 7\sqrt{2} ÷ hypotenuse

hypotenuse = 7\sqrt{2} ÷ sin(45)

*********************

Keep in mind

sin(45) = √2÷2

*********************

so we have:  Hypotenuse = 7√2 ÷ (√2÷2)

Hypotenuse= 14.

What is the y-intercept -x+5y=45
Karo-lina-s [1.5K]

To find the y-intercept, we can convert this to slope-intercept form, or replace the value of x with 0 and solve for y.

We'll do both first.

-x + 5y = 45

5y = 45

Divide both sides by 5.

y = 9


Now let's convert it to slope-intercept.

-x + 5y = 45

Add x to both sides.

5y = 45 + x

Divide both sides by 5.

y = 1/5x + 9

y = 9

<h3><u>The y-intercept of our line is 9.</u></h3>
