g(x)=4x^2-16x+7


g(x)=___(x+___)^2+__

Answers

Answer:

[tex]g(x) = 4(x - 2)^2 -9[/tex]

Step-by-step explanation:

Given

[tex]g(x) = 4x^2 - 16x + 7[/tex]

Required

Complete the square

Rewrite so that [tex]x^2[/tex] has 1 coefficient

[tex]g(x) = 4(x^2 - 4x) + 7[/tex]

Take half of the coefficient of x

[tex]\frac{4}{2} = 2[/tex]

Square the result

[tex](\frac{4}{2})^2 = 2^2[/tex]

[tex](\frac{4}{2})^2 = 4[/tex]

Add and subtract the result in the bracket

[tex]g(x) = 4(x^2 - 4x + 4 - 4) + 7[/tex]

Expand the bracket to remove -4

[tex]g(x) = 4(x^2 - 4x + 4) - 16 + 7[/tex]

[tex]g(x) = 4(x^2 - 4x + 4) -9[/tex]

Expand the bracket

[tex]g(x) = 4(x^2 - 2x -2x+ 4) -9[/tex]

Factorize

[tex]g(x) = 4(x(x - 2) -2(x-2)) -9[/tex]

Factor out x - 2

[tex]g(x) = 4((x - 2)(x-2)) -9[/tex]

Express as square

[tex]g(x) = 4(x - 2)^2 -9[/tex]

You and three of your friends buy tickets for a concert so that you sit together in the same row. Write an expression using factorials that could be used to find the probability that you will get the seat on the far left.

Answers

Answer:

[tex]Pr = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]n = 4[/tex]

Required

Probability that you seat on the far left

First, we calculate the total possible seat arrangements.

This is calculated using:

[tex]Total =n![/tex]

[tex]Total =4![/tex]

[tex]Total =4*3*2*1[/tex]

[tex]Total =24[/tex]

Next, the possible seat arrangements if you seat at the far left.

This implies that you can only seat 1 spot while your friends (3) can seat on any of the remaining 3 seats.

i.e.

[tex]You \to 1[/tex]

[tex]Friend\ 1,2,3 \to 3,2,1[/tex]

The number of arrangement is:

[tex]Arrangement = 1 * 3 *2 *1[/tex]

[tex]Arrangement = 6[/tex]

The required probability is:

[tex]Pr = \frac{Arrangement}{Total}[/tex]

[tex]Pr = \frac{6}{24}[/tex]

Simplify

[tex]Pr = \frac{1}{4}[/tex]

Stella rolls a standard six-sided die, numbered from 1 to 6. Which word or phrase describes the probability that she will roll a number less than or equal to 5? \text{impossible}impossible \text{certain}certain \text{unlikely}unlikely \text{likely}likely

Answers

The probability of getting a number less than or equal to 5 is 5/6.

What is probability?

"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".

For the given situation,

Stella rolls a standard six-sided die, numbered from 1 to 6.

The sample space for rolling a single die = {1, 2, 3, 4, 5, 6}

⇒[tex]n(s)=6[/tex]

The event is getting a number less than or equal to 5.

E = { [tex]{1, 2, 3, 4, 5}[/tex] }

⇒[tex]n(e)=5[/tex]

Thus the probability of getting a number less than or equal to 5,

[tex]P(e) =\frac{n(e)}{n(s)}[/tex]

⇒[tex]P(e)=\frac{5}{6}[/tex]

Hence we can conclude that the probability of getting a number less than or equal to 5 is 5/6.

Write and solve an equation to find the value of x

Answers

Answer:

180 - (52 + 28) = x and then x = 100.

Step-by-step explanation:

A triangle's angles must ALWAYS add up to 180. No matter what. So, the problem gives us 2 of the three angles already, 52 and 28. 52 + 28 is 80. As I mentioned before, a triangle's angles must always add up to 180, so to find x, you must subtract 80 from 180, getting 100. Therefore, x is 100 degrees.

The equation we used to find that is: 180 - (52 + 28) = x.

52 and 28 are the two angles we know, and subtracting their sum from 180 gives us the missing angle.

Mrs. Lee uses 9 cups of water for every
2 cups of rice. How many cups of water
are needed for 5 cups of rice?

Answers

22.5 cups of water

First off, since we know that 9 cups of water is used for every 2 cups of rice. We can just double 9 to make 18, which would now count as 4 cups of rice.
Then you would half the 9 cups of water to find out how many cups of water is used for 1 cup of rice, which is 4.5.
Add them up you get 22.5

If a system of two linear equations has infinitely many solutions, which of the following statements describes the graph of the corresponding two lines in the Iy-plane?
A The lines are coinciding.
B The lines are intersecting at only one point.
c The lines are parallel.
The lines are perpendicular.

Answers

Answer:

A.

Step-by-step explanation:

The lines touch along every point so they are on top of each other.

The given system of equations represent two coinciding lines.

What is a system of linear equations?

A system of linear equations is a group of  equations having same number of variables and degree.

For the n number of variables n number of equations are required.

On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.

A linear equation in two variables represent a straight line.

As system of equations in two variables can be represented as

a₁x + b₊y + c₁ = 0

a₂x + b₂y + c₂ = 0

When there are two such equations having infinite solutions the relation between the coefficients is given as,

a₁/a₂ = b₁/b₂ = c₁/c₂

It implies that there are infinite points common between them which is possible only when these two lines are coinciding.

Hence, the graph of corresponding two lines in the x- y plane represents coinciding lines.

Tuan is an artist. He is painting on a large canvas which is 49 inches wide. The height of the canvas is 3 inches less than the width. What is the area of Tuan's canvas? The area of the canvas is square inches

Answers

Given:

Width of the canvas = 49 inches

The height of the canvas is 3 inches less than the width.

To find:

The area of the canvas.

Solution:

It is given that,

Width of the canvas = 49 inches

The height of the canvas is 3 inches less than the width

So, the height of the canvas is:

[tex]h=49-3[/tex]

[tex]h=46[/tex]

We know that the shape of the canvas is a rectangle and the area of the rectangle is:

[tex]A=length\times width[/tex]

The two dimensions of the canvas are  46 inches and 49 inches. So, the area of the canvas is:

[tex]A=46\times 49[/tex]

[tex]A=2254[/tex]

Therefore, the area of the canvas is 2254 square inches.
