Answer: B. x = 16/3

3/5x + 1/2 = 3/4x -3/10

minus 3/4x on both sides

-3/20x + 1/2 = -3/10

minus 1/2 on both sides

-3/20x = -3/10

multiply both sides by 20/-3

x = 16/3

Answer:

B) [tex]x=\frac{16}{3}[/tex]

Step-by-step explanation:

[tex]\frac{3}{5}x+\frac{1}{2}=\frac{3}{4}x-\frac{3}{10}[/tex]

[tex]\frac{12}{20}x+\frac{10}{20}=\frac{15}{20}x-\frac{6}{20}[/tex]

[tex]\frac{10}{20}=\frac{3}{20}x-\frac{6}{20}[/tex]

[tex]\frac{16}{20}=\frac{3}{20}x[/tex]

[tex]16=3x[/tex]

[tex]\frac{16}{3}=x[/tex]

Therefore, your answer is B) [tex]x=\frac{16}{3}[/tex]

Answers

Given:

The polynomials are:

[tex]3x^2y^2-2xy^5[/tex]

[tex]-3x^2y^2+3x^2y^2+3x^4y[/tex]

To find:

The completely simplified sum of the polynomials.

Solution:

We have,

[tex]3x^2y^2-2xy^5[/tex]

[tex]-3x^2y^2+3x^2y^2+3x^4y[/tex]

The sum of given polynomials is:

[tex]Sum=3x^2y^2-2xy^5-3x^2y^2+3x^2y^2+3x^4y[/tex]

[tex]Sum=-2xy^5+3x^4y+3x^2y^2[/tex]

Therefore, the sum of the given polynomials is [tex]-2xy^5+3x^4y+3x^2y^2[/tex]. It is a polynomial with degree 6 and leading coefficient -2.

Applying the angle of intersecting tangents theorem, m∠ABC = 99°

What is the Angle of Intersecting Tangents Theorem?

If two tangents intersect and form an angle outside a circle, based on the angle of intersecting tangents theorem, the angle formed equals half the positive difference of the intercepted arcs.

Given the following:

m(AD) = (17x + 2)m(AC) = (7x – 10)m∠ABC = (4x + 15),

Apply the angle of intersecting tangents theorem:

m∠ABC = 1/2[m(AD) - m(AC)]

Substitute

4x + 15 = 1/2[(17x + 2) - (7x - 10)]

2(4x + 15) = 17x + 2 - 7x + 10

8x + 30 = 10x - 12

8x - 10x = -30 - 12

-2x = -42

x = -42/-2

x = 21

m∠ABC = (4x + 15)

Plug in the value of x

m∠ABC = 4(21) + 15 = 99°

Ok so 18x13 is 234. 234x21 is 4,914. Now we have the volume of the box (4,914).

as we know 18x13 is 234. So if we multiply 234x12 we get 2,808. So now all we have to do is divide 2,808 by 2. That gives us 1,404.

Find the​ fourth-degree polynomial function with zeros 4​, -4, 4i ​, and -4i . Write the function in factored form.

Answers

Given:

A fourth-degree polynomial function has zeros 4​, -4, 4i ​, and -4i .

To find:

The fourth-degree polynomial  function in factored form.

Solution:

The factor for of nth degree polynomial is:

[tex]P(x)=(x-a_1)(x-a_2)...(x-a_n)[/tex]

Where, [tex]a_1,a_2,...,a_n[/tex] are n zeros of the polynomial.

It is given that a fourth-degree polynomial function has zeros 4​, -4, 4i ​, and -4i. So, the factor form of given polynomial is:

[tex]P(x)=(x-4)(x-(-4))(x-4i)(x-(-4i))[/tex]

[tex]P(x)=(x-4)(x+4)(x-4i)(x+4i)[/tex]

[tex]P(x)=(x-4)(x+4)(x^2-(4i)^2)[/tex]           [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

On further simplification, we get

[tex]P(x)=(x-4)(x+4)(x^2-4^2i^2)[/tex]

[tex]P(x)=(x-4)(x+4)(x^2+16)[/tex]                [tex][\because i^2=-1][/tex]

Therefore, the required fourth degree polynomial is [tex]P(x)=(x-4)(x+4)(x^2+16)[/tex].

The fourth degree polynomial is given by f(x) = (x - 4)(x + 4)(x + 4i)(x - 4i)

Polynomial

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

Polynomials can be classified based on degree as linear, quadratic, cubic, fourth degree.

Let f(x) represent the function with zeros 4​, -4, 4i ​, and -4i. Hence:

x = 4; x = -4; x = 4i; x = -4i

x - 4 = 0; x + 4 = 0; x - 4i = 0; x + 4i = 0

f(x) = (x - 4)(x + 4)(x + 4i)(x - 4i)

The fourth degree polynomial is given by f(x) = (x - 4)(x + 4)(x + 4i)(x - 4i)

What is meant by value?Depending on where it is in the number, each digit has a different value, which is referred to as value. We figure it out by multiplying the digit's place value by its face value. Location value plus face value equals value. For illustration: If we take 45 into account. Here, the fourth digit is in the tens column. The value a digit in a number represents based on where it is in the number is known as place value. For instance, 700 is the place value of 7 in 3,743. Nevertheless, 7,000 or 7,000 is the place value of 7 in 7,432.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that line that includes the points (4,−5) and (8,−7).

The slope will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -7 +5  ) / ( 8 - 4)

Slope = -2 / 4= -1/2

The y-intercept will be calculated as,

y = mx + c

-7 = -1/2 x 8 + c

-7 = -4 + c

c = -3

The equation can be written as,

y = mx + c

y= -1/2(x) - 3
