This question tests one's knowledge of states of matter. Kim would have to classify the water as gaseous matter in this case.

<h3>Why should Kim classify the water as gaseous?</h3>

Remember, she boiled all the liquid away. Hence in their evaporated state, the water now assumes a gaseous form.

Matter can exist in various states. They are:

  • Solids;
  • Liquids;
  • Gaseous;
  • Plasma; and
  • Bose-Einstein condensate. (which is Man-made).

Which of the following equations belongs to an ellipse with vertical orientation?
Mekhanik [1.2K]

Answer:

d. 16x² + y² = 16

Step-by-step explanation:

Standard form of an ellipse is:

x² / a² + y² / b² = 1

If b > a, the ellipse has a vertical orientation.

We can ignore options b and c, since they have minus signs in them.

Convert the other options to standard form:

a. x² / (1/16) + y² / (1/25) = 1

x² / (1/4)² + y² / (1/5)² = 1

1/4 > 1/5

d. x² + y² / 16 = 1

x² / 1² + y² / 4² = 1

1 < 4

e. x² / 16 + y² = 1

x² / 4² + y² / 1² = 1

4 > 1

Of these three options, only d is a vertical ellipse.

I need some help with this one. Please give it a go! Thank you for your time!

Answer:

y = 4x - 3

Step-by-step explanation:

When we re-write the given equation into its slope-intercept form, it will like this:

y = (-1/4)x - 6

This line has a slope equal to -1/4 so the slope of the required line has a slope of +4 (perpendicular to the given line). Use this new slope and the given point P0(-1, -7) into this equation:

y - y0 = m(x - x0) ---> y + 7 = 4(x + 1)

Rearranging the terms into its slope-intercept form, we get

y = 4x - 3
