Complete the square to write the equation, 4x2 24x – y 43 = 0, in standard form. y = (x )2

Answers

An equation is formed of two equal expressions. The equation 4x²+24x-y+43=0 in the standard form of y=(x)² is written as (y-7)=(2x+6)².

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation that is given to us is 4x²+24x-y+43=0, and we need to write the given equation in the form of y=(x)². Therefore, the equation can be solved in the following steps,

[tex]4x^2+24x-y+43=0\\\\4x^2+24x-y+36+7=0\\\\(4x^2+24x+36)-y+7=0\\\\(2x+6)^2-(y-7)=0\\\\(y-7)=(2x+6)^2[/tex]

Hence, the equation 4x²+24x-y+43=0 in the standard form of y=(x)² is written as (y-7)=(2x+6)².

Step-by-step explanation:

Correct equations:

  8x+y=4

 -2x-8=y

------------------

Rearrange the first equation:

8x+y=4

y=4-8x

Now use this value of y in the second equation:

-2x-8=y

-2x-8=4-8x

6x = 12

x = 2

When x = 2:

y=4-8x

bellamy is building a gate to put on a fence. the gates measurements are 7 feet by 7 feet a diagonal wooden brace is going to be attached to keep the gate rigid what is the length of wood bellany needs to cut for the brace leave your answer in simplified radical form

Answers

The length of the diagonal is the hypotenuse of the fence

The length of the wood is [tex]7\sqrt{ 2[/tex] yards

How to determine the length of the wood?

The dimensions of the fence are:

7 ft by 7 ft

The length (L) of the diagonal is calculated using:

[tex]L = \sqrt{a^2 + b^2[/tex]

This gives

[tex]L = \sqrt{7^2 + 7^2[/tex]

Express as products

[tex]L = \sqrt{7^2 * 2[/tex]

Express as radical

[tex]L = 7\sqrt{ 2[/tex]

Hence, the length of the wood is [tex]7\sqrt{ 2[/tex] yards

What are polynomials?

Polynomials are algebraic expressions having only addition, subtraction, multiplication and exponentiation (non-negative) of variables involved in it.

What are terms in polynomials?

Terms are added or subtracted to make a polynomial. They're composed of variables and constants all in multiplication.

Example:

[tex]x^3 + 3x +5[/tex]

is a polynomial consisting 3 terms as

[tex]x^3[/tex], 3x and 5

If there is one term, the polynomial will be called monomial.If there are two terms, the polynomial will be called binomialIf there are three terms, the polynomial will be called trinomial

Checking all the options:

Option 1: [tex]xy\sqrt{8}[/tex]

It has only one term, so its not a binomial.

Option 2: [tex]x^2y - 3x[/tex]

It has two terms, and there is only integer powers of variables and variables are in multiplication in forming terms, so its a polynomial.  And because of two terms and being polynomial, it is binomial.

Option 3: [tex]y^2 + \sqrt{y}[/tex]

Because of square root over variable 'y', the variable 'y' got non-integer power 1/2 as square root is also written as exponentiation by 1/2.

Thus, its not a polynomial.

Option 4: [tex]4xy - 2/5\\[/tex]

Its a polynomial as there are constants only and variables with multiplication. And because of two terms and being polynomial, it is binomial.

Option 5: [tex]x^2 + \dfrac{3}{x}[/tex]

we can write the second term as:

[tex]\dfrac{3}{x} = 3x^{-1}[/tex]

Thus, the variable x has negative power. Thus, its not a polynomial. Or simply, since the variable is in division in simplified form, therefore, its not a polynomial.

Thus, the algebraic expressions out of the given options that are binomials is given by: Option B: x^2y - 3x and Option D: 4xy - 2/5

The volume of an sphere of radius r is given by:

[tex]V = \frac{4\pi r^3}{3}[/tex]

In this problem, there are three spheres, of radius r = 1 m, r = 5 m and r = 2 m, hence:

[tex]V_1 = \frac{4\pi}{3} = 4.19[/tex]

[tex]V_3 = \frac{4\pi \times 2^2}{3} = 16.76[/tex]

The total volume, in cubic meters, is of:

V = 4.19 + 104.72 + 16.76 = 125.67.

Answers

Answer:

z = 5*(1/2)

z = 5/10

time switching classes:

w = 7/10

y - 6x - z - w = 0

6x = y - z - w

x = (y - z - w)/6

x = (76/10 - 5/10 - 7/10)/6

x = (76 - 5 - 7)/(10*6)

x = (64)/(10*6)

x = (2*2*2*2*2*2)/(2*5*2*3)

x = (2*2*2*2)/(5*3)

y = 7.6

z = 1/2

z = 0.5

w = 7/10

w = 0.7

y - 6x - z - w = 0

6x = y - z - w

x = (y - z - w)/6

x = (7.6 - 0.5 - 0.7)/6

x = 1.0666666666

what is the area of this figure?

Answers

Answer:

  234 square millimeters

Step-by-step explanation:

You want the area of the irregular polygon shown.

Composition

There are always several ways you can find the area of a figure like this. In the attachment we have shown extensions of the vertical and horizontal lines that will divide the figure into a triangle and two rectangles.

Triangle area

The triangle has a base of 12 mm and a height of 13 mm. Its area is ...

  A = 1/2bh

  A = 1/2(12 mm)(13 mm) = 78 mm²

Rectangle area

The upper rectangle has a width of 8 mm and a length of 14 mm. Its area is ...

  A = LW

  A = (14 mm)(8 mm) = 112 mm²

The lower rectangle has a width of 4 mm and a length of 11 mm. Its area is ...

  A = (4 mm)(11 mm) = 44 mm²

Total area

The area of the figure is the sum of the areas of its parts:

  total area = triangle area + upper rectangle + lower rectangle

  total area = 78 mm² + 112 mm² + 44 mm² = 234 mm²

The area of the figure is 234 square millimeters.

Write an equation for the graph in terms for xY= Theo's older brother, Antonio, was learning carpentry, and over the past few months, he had transformed the shed into his carpentry workshop. Theo always looked up to Antonio and tried to be like him. He was fascinated by all the wonderful objects Antonio had carved from wood, and longed to try his hand at carpentry too. But every time he asked Antonio if he could operate one of his cool carpentry tools, Antonio's response was always the same. "You're too young to use these tools, Theo. They might look fun to use, but trust me, they are not easy to operate." That day, Antonio was building an intricate model of a house. He had been working on it for weeks, and the model was nearly complete. Suddenly, Antonio realized that he needed to run to the store to buy more nails. As soon as he left, Theo approached Antonio's work area and began to look around with glee. When his eyes fell on the power drill, which was still connected to the power socket, he smiled mischievously. He picked it up and switched it on, aiming it at a piece of wood lying on the table. But the drill was heavier than he imagined, and he could not hold on to it as it vibrated powerfully in his hand. Panicking, Theo dropped the drill and in his haste, he tripped over the wire on the floor. Losing balance, he went crashing into the table, knocking over Antonio's model house as he went down. It fell to the floor and broke into pieces. As Theo stared in shock at the mess he had created, Antonio came back into the shed. Theo immediately began to apologize. "I too was curious and brash when I was your age, little brother. But experience has taught me to be more careful and responsible. When you're older, I'll teach you to operate these tools," Antonio said. Theo apologized again and helped his brother clean up the mess.What is the best summary of the passage? A. Theo watches his elder brother Antonio making things in their shed and asks Antonio to let him use his carpentry tools, but Antonio does not allow him to use them. Theo tries to use Antonio's power drill when he is away, and destroys Antonio's model house. Theo is worried that his brother will be upset. B. Theo is fascinated by his older brother Antonio's carpentry tools. One day in Antonio's absence, Theo plays with his power drill and ends up breaking a model house and making a mess. Theo apologizes to Antonio, who advises his younger brother to be careful and operate these tools when he is older. C. Theo loves watching Antonio make beautiful things using his modern carpentry tools, and longs to use the tools himself. But Antonio tells him that the tools are not easy to operate. However, when Antonio is away, Theo plays with a power drill, drops it on the floor, and destroys Antonio's model house. D. Theo watches his brother Antonio make things in his carpentry workshop. Antonio does not let Theo use his carpentry tools because he feels Theo is too inexperienced to use them and may harm himself. Theo examines Antonio's power drill when Antonio is away, and while doing so drops it on the floor.
