The factors of the given expression are 5x², (x - 2), and (x - 2).

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.

It is given that the polynomial expression 5x⁴ – 20x³ + 20x²

It is required to find its factor.

We have a polynomial expression let's denote it with f(x)

f(x) = 5x⁴ – 20x³ + 20x²

taking 5x² common

f(x) = (x²-4x +4)  5x²

from the formula (a -b)² = a² +b² -2ab

f(x) = (x -2)²*5x²

Thus, the factors of the given expression are 5x², (x - 2), and (x - 2).

Answer:

Option (3) is the answer.

Step-by-step explanation:

Given question is incomplete; find the complete question in the attachment.

Jewelry made by Nala is a composite figure having three fourth of a circle and two sides of a square.

Perimeter of the whole figure will give us the length of wire needed to design the jewelry.

Perimeter of three fourth of a circle P(circle) = [tex]\frac{3}{4}(2\pi r)[/tex]

Here, r = radius

P(circle) = [tex]\frac{3\pi (3)}{2}[/tex]

             = 14.14 cm

Perimeter of the complete (composite) figure = 14.14 + 3 + 3

                                                                            = 20.13

                                                                            ≈ 20.1 cm

Therefore, Option (3) is the answer.

x² - 2(x)(0.5) + 0.5² - 2.25

x² - x + 0.25 - 2.25

x² - x - 2

Answer:

It's the first answer. Remember, equations like that are always y=mx+b. Y is whatever y value, m is the slope, x whatever the x value is. b is the y intercept (the y value when x equals 0). In this case, you can tell that 1/2 and 2 are the m, m is slope, so the first option should be correct.

Answer:

0.524

Step-by-step explanation:

The probability that the chosen student is a male is 0.524 .

Given,

Number of male students who participated in sports = 110

Number of female students who participated in sports = 100

Number of male students who did not participated in sports = 180

Number of female students who did not participated in sports = 210

Now,

The probability that the male students is chosen will be given by,

P(MALE) = 110/210

P(MALE) = 55/105

P(MALE) = 11/21

P(MALE) = 0.524

Thus the probability of chosing a male student who participates in the sport is 0.524 .

Answer:

A = 38°

B = 50.32°

C = 91.68°

a = 8

b = 10

c = 12.77

Step-by-step explanation:

The first thing is to find the angle B, like this:

sin B = b * sin A / a = 10 * sin (38 °) / 8

sin B = 0.77

B = arc sin (0.77)

B = 50.32 °

For angle C, it would be:

C = 180 - 38 - 50.32

C = 91.68 °

Side c, we calculate it like this:

c = a * sin C / sin A = 8 * sin (91.68 °) / sin (38 °)

c = 12.77

Step-by-step explanation:

Because there is a three, we must do three times both of the terms:

(3 x 4m) + (3 x 2)

When you do it, we get:

12m + 6

We cannot simplify it any further, so 12m + 6 is out final answer.

Answer:

[tex]\frac{x^{2} }{1} +\frac{y^{2} }{2}=1[/tex]

Step-by-step explanation:

The directrices of an ellipse are defined by

[tex]x=(+-)\frac{a}{e}[/tex]

Where [tex]a >b[/tex], and [tex]e[/tex] is the eccentricity defined by [tex]e=\frac{c}{a}[/tex]

So, in the first choice, we have the equation

[tex]\frac{x^{2} }{4}+\frac{y^{2} }{1} =1[/tex]

Where [tex]a^{2}=4[/tex] and [tex]b^{2}=1[/tex], which means [tex]a=2[/tex] and [tex]b=1[/tex].

In an ellipse, we have the relation

[tex]c^{2}=a^{2}-b^{2}[/tex]

Replacing values, we have

[tex]c^{2} =4-1=3\\c=\sqrt{3}[/tex]

So, the eccentricity is [tex]e=\frac{\sqrt{3} }{2}[/tex] and the directrices are [tex]x=(+-)\frac{2}{\sqrt{3} }[/tex], which means the first choice is not the right answer. In other words, the right answer is the second choice, because third and fourth choices don't represent an ellipse, both fractions must be positive in that case.

Therefore, the right answer is

[tex]\frac{x^{2} }{1} +\frac{y^{2} }{2}=1[/tex]

Final answer:

There are 45 students in the class.

Explanation:

If 18 girls represent 40% of a class, we can calculate the total number of students in the class using the concept of percentages. To find the total number of students, we set up a proportion, which is an equation that says two ratios are equivalent.

We know that 18 girls are to 40% what the total number of students is to 100%, since 100% would be the whole class.
We can express this relationship with the equation:

18 (number of girls) / (total number of students) = 40% / 100%
Using cross-multiplication, we can find the total number of students:
18 / x = 40 / 100
x = (18 * 100) / 40
x = 1800 / 40
x = 45
So, there are 45 students in the class list.

Final answer:

To find out how much money will be in the account after 8 years with $200 initial investment and a 3% interest compounded monthly, use the compound interest formula A = P(1 + r/n)^(nt). The calculation results in approximately $256.67 in the account after 8 years.

Explanation:

To calculate how much money will be in the savings account after 8 years with an initial investment of $200 and a 3% interest rate compounded monthly, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

In this case, P = $200, r = 0.03, n = 12 (since interest is compounded monthly), and t = 8.

The formula becomes:

A = 200(1 + 0.03/12)^(12*8)

Calculating this we get:

A = 200(1 + 0.0025)^(96)

A = 200(1.0025)^96

A = 200(1.283362)

A ≈ $256.67

After 8 years, the savings account will have approximately $256.67.
