Describing part to part realationship

Mathematics
1 answer:
Leokris [45]3 years ago

Answer:

If you mean a part to part ratio, this basically describes a ratio or relationship that compares two different groups.

Step-by-step explanation:

If you mean a part to part ratio, this basically describes a ratio or relationship that compares two different groups.

An example would be if I compared the number of dogs to cats in a house. If there were 10 dogs and 3 cats, I would write 10:3.

Hope this helped! God bless and stay safe :)

Prove that if {x1x2.......xk}isany
Radda [10]

Answer:

See the proof below.

Step-by-step explanation:

What we need to proof is this: "Assuming X a vector space over a scalar field C. Let X= {x1,x2,....,xn} a set of vectors in X, where n\geq 2. If the set X is linearly dependent if and only if at least one of the vectors in X can be written as a linear combination of the other vectors"

Proof

Since we have a if and only if w need to proof the statement on the two possible ways.

If X is linearly dependent, then a vector is a linear combination

We suppose the set X= (x_1, x_2,....,x_n) is linearly dependent, so then by definition we have scalars c_1,c_2,....,c_n in C such that:

c_1 x_1 +c_2 x_2 +.....+c_n x_n =0

And not all the scalars c_1,c_2,....,c_n are equal to 0.

Since at least one constant is non zero we can assume for example that c_1 \neq 0, and we have this:

c_1 v_1 = -c_2 v_2 -c_3 v_3 -.... -c_n v_n

We can divide by c1 since we assume that c_1 \neq 0 and we have this:

v_1= -\frac{c_2}{c_1} v_2 -\frac{c_3}{c_1} v_3 - .....- \frac{c_n}{c_1} v_n

And as we can see the vector v_1 can be written a a linear combination of the remaining vectors v_2,v_3,...,v_n. We select v1 but we can select any vector and we get the same result.

If a vector is a linear combination, then X is linearly dependent

We assume on this case that X is a linear combination of the remaining vectors, as on the last part we can assume that we select v_1 and we have this:

v_1 = c_2 v_2 + c_3 v_3 +...+c_n v_n

For scalars defined c_2,c_3,...,c_n in C. So then we have this:

v_1 -c_2 v_2 -c_3 v_3 - ....-c_n v_n =0

So then we can conclude that the set X is linearly dependent.

And that complet the proof for this case.

PLEASE ANSWER ILLG IVE YOU BRAINLIEST
Yuri [45]

Answer:

#1. 31.4 square units

Step-by-step explanation:

We are solving for the square units and also we are circumference formular

which is C = R x 2) (3.14)

R is 5 but in a case they don't give us the Radius and gives us the Diameter we decide the Diameter by 2 and we will get the radius.

Back to the problem

C = R x 2) (3.14)

C =  5 x 2 x 3.14

C = 10 x 3.14

C = 31.4
