Four points are always coplanar if they: Check all that apply. A. lie on the same line. B. lie on different planes. C. lie on different lines. D. lie in the same plane.

Answers

Answer 1

Answer: D. lie in the same plane.

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.

A. lie on the same line.

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.

Finally, the correct answers are A. and D.

Answer 2

Answer:

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.

Carrots sell for $2.10 per pound, and crackers sell for $2.90 per pound. Glen bought some carrots and some crackers. The total weight was 2.3 pounds and cost $6.03.How many pounds of carrots and how many pounds of crackers did Glen buy? A.0.5 pounds of carrots; 1.8 pounds of crackers B.0.8 pounds of carrots; 1.5 pounds of crackers C.1 pound of carrots; 1.3 pounds of crackers D.1.5 pounds of carrots; 0.8 pound of crackers

Answers

You can solve this problem by adding/subtracting expressions.

You have two expressions here: x + y = 2.3 and 2.1x + 2.9y = 6.03

The goal is to get rid of one of the variables because when there are two variables it's pretty impossible to figure them out when you don't know either. To do this you need to add or subtract the expressions. To do that you need to make one of the variables the same in both expressions.

Let's make the x's the same. So in one problem you have x and in the other you have 2.1x. You want to multiply the x by 2.1 so they are both 2.1 x. To do that you have to multiply the whole expression by 2.1 which would be 2.1(x + y) = 2.3(2.1) which equals 2.1x + 2.1y = 4.83.

Now you have two expression 2.1x + 2.1y = 4.83 and 2.1x + 2.9y = 6.03. Change the first one to all negatives to subtract it. 2.1x + 2.1y = 4.83 becomes -2.1x - 2.1y = -4.83. Now you can subtract the expression like this.

2.1x + 2.9y = 6.03
-2.1x - 2.1y = -4.3
________________
0x + 0.8y = 1.2 or 0.8y = 1.2 (Hooray the x is gone!)

Now you just finish solving it.

0.8y = 1.2
y = 1.2/0.8
y = 1.5

y represented the crackers so whatever answer has 1.5 crackers is the correct one

Find the product and simplify your answer 6n^5(7n^4-5n+5) 40 points

Answers

We have the following expression:
6n ^ 5 (7n ^ 4-5n + 5)
We can rewrite the expression using power properties.
We have then:
42n ^ (4 + 5) - 30n ^ (1 + 5) + 30n ^ 5
Rewriting:
42n ^ 9 - 30n ^ 6 + 30n ^ 5
Answer:
the product is:
42n ^ 9 - 30n ^ 6 + 30n ^ 5
