What is the smallest number of distinct points that can define a plane?

1 answer:

4 0

The smallest number of distinct points that can define a plane would be 3 points. Below this value, you cannot create a plane, you can only create a line or a point. A plane that has three point is called a triangle. Hope this helps. Have a nice day.

When Carla solved for the height from the ground to the point where the ladder

Westkost [7]

Answer:

<em>See explanation</em>

Explanation:

Given

Represent the vertical angle with $\theta$

$\theta = 75$

The question has incomplete details because the length of the ladder is not given; neither is the distance between the ladder and the wall given.

<em>See attachment for illustration</em>

So, this solution will be based on assumptions.

Represent

- The height from ground to the top of the ladder with y

- The length of the ladder with L

- The distance between the ladder and the wall with x

Carla could solve for y in any of the following ways:

1. Tan formula

$tan \theta = \frac{opp}{adj}$

In this case:

$tan \theta = \frac{x}{y}$

Multiply both sides by y

$y * tan \theta = \frac{x}{y} * y$

$y * tan \theta = x$

Divide both sides by tan

$y = \frac{x}{tan \theta}$

$y = \frac{x}{tan 75}$

This can be used if the distance (x) between the ladder and the wall is known.

Assume x = 15

$y = \frac{15}{tan 75}$

$y = 4.02$

2. Cosine formula

$cos \theta = \frac{adj}{hyp}$

In this case:

$cos \theta = \frac{y}{L}$

Multiply both sides by L

$L * cos \theta = \frac{y}{L} * L$

$Lcos \theta = y$

$y = Lcos \theta$

$y = Lcos75$

This can be used if the length (L) of the ladder is known.

Assume L = 15

$y = 15 * cos75$

$y = 3.88$

Is atmospheric pressure the same everywhere on the surface of the earth?

vitfil [10]

Answer:

Atmospheric pressure differs in different parts of the world.

Explanation:

This is because atmospheric pressure depends on the height of a particular location on earth.
A number of locations on the earth are at sea level. The atmospheric pressure at sea level is 14.7 pounds per square inch.
At higher levels (altitudes) the atmospheric pressure is lower since higher places have got less air pushing downwards compared to lower altitudes which have more air pushing down and hence, high atmospheric pressure.
