Answer:

Options A  and D.

Step-by-step explanation:

Coplanar points are points that lie in same plane. If 4 points are in same line they are collinear and  then they will be coplanar. If the 4 given points lie in same plane then also they will be coplanar. If they do not lie in same plane they will not be coplanar. The points can lie on different lines. Four or more points might or might not be coplanar.

The correct options are  A and D.

<span>D. lie in the same plane.
</span><span>
The definition of capillarity is that points are considered as co-planar when these points are on the same plane, so it is obvious that the answer D is true because this statement is the definition of capillarity. This is shown in Figure 1.

</span><span>A. lie on the same line.
</span><span>
If four points lie on the same line then there will be a plane that contains this line, therefore the definition is fulfilled. This is shown in Figure 2.

</span><em>Finally, the correct answers are A. and D.</em>

in 2005, the total waste generated in a certain country was 3.474x10^9 pounds. also in 2005, the countrys population was 1.23x10
Serggg [28]

Answer:

2824

Step-by-step explanation:

Take the number of pounds and divide by the number of people:

3.474×10⁹ / 1.23×10⁶

Divide the coefficients and subtract the exponents:

(3.474 / 1.23) × 10⁹⁻⁶

2.824×10³

So the country produced about 2,824 pounds of garbage per person in 2005.

Suppose triangle ABC has vertices at A(1, 0), B(10, 0), and C(2, 6). After a 60° counterclockwise rotation about the origin, ver
Artemon [7]
Check the picture attached.

Let OB be the radius of circle with center O.

Let B' be the image of B after the described rotation

OB and OB' are sides of the equilateral triangle OBB'.

The x coordinate of B' is the midpoint of OB, that is 5.

In the right triangle B', point (5, 0) and B:

Distance point (5, 0) to B is 5
|B'B|=|OB|=10

so by the pythagorean theorem:

a= \sqrt{ 10^{2} - 5^{2} } = \sqrt{ 2^{2} *5^{2} - 5^{2} }= \sqrt{5^{2}(4-1)}=5 \sqrt{3} units



Answer: 5 \sqrt{3}

Geometry problem in the picture: Find the measure of the angle to the nearest degree
Anit [1.1K]

Answer:

? Is 41 degrees

Step-by-step explanation:

SOH CAH TOA

Hypotenuse is 60

Adjacent is 45

Hypotenuse and adjacent - Cos

(Cos inverse to find the angle)

Cos(?) = a/h

Cos(?) = 45/60

Cos-(45/60) =?

? = 41.40962211

Hope this helps!
