The factor of the provided polynomial with the after the factorization process are similar to option A, which is

3xy(x^3y^2 - 5xy+ 2)

<h3>What is factor of polynomial?</h3>

The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.

The given polynomial equation in the problem is,

3x^4y^3 - 15x^2y^2+ 6xy

The above equation has the unknown variable x and y and the highest power of this unknown variable is 3.

Take out the highest common factor 3, which can divide each term of the above equation (3, 15, 6). Thus,

3(x^4y^3 - 5x^2y^2+ 2xy)

Take out the highest common factor in terms of variable, which can divide each term of the above equation. Thus,

3xy(x^3y^2 - 5xy+ 2)

Thus, the factor of the provided polynomial with the after the factorization process are similar to option A, which is

3xy(x^3y^2 - 5xy+ 2)

Which pair of numbers has a GCF of 3? (A) 1 and 6 (B) 2 and 3 (C) 2 and 6 (D) 3 and 4
Elden [556K]

Answer:

None of the above

Step-by-step explanation:

To find the GCF of something find the prime factorization of each number, then see which numbers are the same. After that multiply the numbers that are the same.

(PF): Prime Factorization

A: PF - 1   PF - 2 · 3 (Since they don't have any numbers in common the GCF is 1)

B: PF - 2  PF - 3 (The GCF is also 1)

C: PF - 2  PF - 2 · 3 (Because they have 2 in common the GCF is 2)

D: PF - 3  PF - 2 & 2 (The GCF is 1)

None of the options have a GCF of 3. Therefore it is none of the above

Commercial dredging operation in ancient rivers occasionallyuncover archaeological artifacts of great importance. One suchartifa
Ivenika [448]

Answer:

A) Refer attached fig. or pareto chart

Step-by-step explanation:

Given data

Rivers               Bann    Blackwater    Erne     Shannon    Barrow

Spearheads(fi)     19          8                    15          33               14

a)

Pareto charts are those charts  who has both bars and lines.  bars are shown in descending order and the cumulative total is represented by the line.

b) Circle graph

Circle graph is also known as pie chart

In this chart we divided into circle in to different segments according to formula.

Total  frequency of spreads in = 19+8+15+33+14=90

i) Bann

fi =19

percentage = \frac{19}{90}\times100 = 21.35%

Segment size = 21.35% × 360 = 77°

ii) Black water

fi = 8

percentage = \frac{8}{90} \times 100 = 8.99%

Segment size = 8.99% × 360 = 32°

iii) Erne

fi = 15

percentage = \frac{15}{90} \times 100 = 16.85%

Segment size = 16.85% × 360 = 61°

iv) Shannon

fi = 33

percentage = \frac{33}{90}\times100 = 37.08%

Segment size = 37.08% × 360 = 133°

iv) Barrow

fi = 14

percentage = \frac{14}{90} \times100 = 15.73%

Segment size = 15.73% × 360 = 57°
