Answer:

(x+2)^2

Step-by-step explanation:

x^2+4x+2^2

Simplify!!!

x^2 + 4x +4

2^2 is also know as squaring when a number is multiplied by itself, 2 x 2

Now time to factor, what you need to look at is the last two numbers and ask...

What two numbers add to give me 4 and multiply to give me 4

We look at the factors of 4: 1,2,2,4

As you can tell 1 and 4 definitely don't work because 1+4=5 or 1-4= -3 and so forth

Therefore 2,2 are the numbers we need!! Lets check just in case

2 +2 gives us 4 or 4x in this case

and 2 x 2 gives 4

Therefore when you factor you place the equation in factored form

(x+2)^2

The equation of the profit function is P(x) = 269x - 4x^2 - 128

The profit function P(x) can be found by subtracting the cost function C(x) from the revenue function R(x), where R(x) = p * x:

So, we have

P(x) = R(x) - C(x)

Substitute the known values in the above equation, so, we have the following representation

P(x) = (285 - 4x) * x - (128 + 16x)

So, we have

P(x) = 285x - 4x^2 - 128 - 16x

Evaluate the like terms

P(x) = 269x - 4x^2 - 128

To find the profit for making and selling 3 million fans, we substitute x = 3 into the profit function P(x):

P(3) = 269(3) - 4(3)^2 - 128

P(3) = 643

For other number of fans, we have

P(5) = 269(5) - 4(5)^2 - 128

P(5) = 1117

P(9) = 269(9) - 4(9)^2 - 128

P(9) = 1969

P(12) = 269(12) - 4(12)^2 - 128

P(12) = 2524

Hence, the profits are 643, 1117, 1969 and 2524

9514 1404 393

Answer:

Step-by-step explanation:

The denominators have the sequence ...

  8, 16, 32, 64, 128, ...

These values have a common ratio of 2, so this is an exponential pattern with a base of 2. Apparently, the multiplier is 4.

  denominator = 4×2^n

The numerators have the sequence ...

  3, 5, 9, 17, 33, ...

These values have no common ratio, but their differences are ...

  2, 4, 8, 16

and those differences do have a common ratio of 2. That means an exponential value of 2^n will figure into the numerator value. When we compare the sequence 2^n = 2, 4, 8, 16, 32 to the actual numerators, we see the numerator values are ...

  numerator = 2^n +1

So, the general term of Tara's fraction is ...

  (2^n +1)/(4·2^n)

__

The first number is found in Tara's table: 3/8

The 7th number is (2^7+1)/(4×2^7) = 129/512

The pattern is ...

  a[n] = (2^n +1)/(4×2^n)

Answer: The function is odd because f(–x) = –f(x).

Step-by-step explanation:

\(f(x)=6x^7\\\\f(-x)=6(-x)^7 = -6x^7\\\\\therefore f(x)=-f(-x)\)

The function is odd because f(–x) = –f(x).

The function is given as:

f(x) = 6x^7

A function is odd if the following is true

f(-x) = -f(x)

Calculate f(-x)

f(-x) = 6(-x)^7

f(-x) = -6x^7

Calculate -f(x)

-f(x) = -6x^7

By comparison;

f(-x) = -f(x) = -6x^7

Hence, the function is odd because f(–x) = –f(x).

First, let's look at each of the four sets of numbers:-

So in which set does \(\bold{-\sqrt{2}}\) belong?

First, it's negative, so it's not a natural number.

Then, it's not an imaginary number, so it doesn't belong in the "Not a real number" set.

It can't be written as a fraction, so it doesn't belong in the "Rational" set, but it does belong in the "Irrational numbers" set.

According to the answer and explanation, we conclude that the number \(\bold{-\sqrt{2}}\) belongs in the "Irrational number" set.

  \(\dfrac{x^2+8x+16}{x-1}\)

Step-by-step explanation:

In general, "over" and "divided by" are used to mean the same thing. Parentheses are helpful when you want to show fractions divided by fractions. Here, we will assume you intend ...

  \(\dfrac{\left(\dfrac{x^2+7x+12}{x+3}\right)}{\left(\dfrac{x-1}{x+4}\right)}=\dfrac{(x+3)(x+4)}{x+3}\cdot\dfrac{x+4}{x-1}=\dfrac{(x+4)^2}{x-1}\\\\=\boxed{\dfrac{x^2+8x+16}{x-1}}\)

Therefore , the solution of the given problem of  probability comes out to be the right response is thus: "Drawing a red card or a Queen from a regular deck of cards is an overlapping occurrence."

The primary objective of statistical inference, a branch of mathematics, is to determine the chance that a claim is true or that a specific event will occur. Chance can be represented by any number between 0 and 1, in which 1 typically represents certainty and 0 typically represents possibility. A probability diagram shows the chance that a specific event will occur.

Here,

Because the Queen of Hearts and Jack of Spades are not face cards or nines,

the occurrences "Drawing a Queen of Hearts or Jack of Spades from a standard deck of cards" and "Drawing a face card or a 9 from the a standard deck of cards" do not overlap.

A Queen of Hearts is both a red card and a queen, and a diamond is a type of red card and a club is a type of card, so the occurrences "Drawing a Diamond or a Club from a Standard Deck of Cards" and "Drawing a Red Card or a Queen from a Standard Deck of Cards" overlap.

The right response is thus: "Drawing a red card or a Queen from a regular deck of cards is an overlapping occurrence."

Answer:

\(C = 2\pi r\\\)

Step-by-step explanation:

\(Circumference = 2\times \pi \times r\)

The length of the third side is 2√34 + 6.

We can use the triangle inequality theorem to solve this problem. According to the theorem, the sum of any two sides of a triangle must be greater than the length of the third side.

Let x be the length of the third side. Then we have:

2√34 + 6 > x

Subtracting 6 from both sides, we get:

2√34 > x - 6

Adding 6 to both sides, we get:

x < 2√34 + 6

Therefore, the length of the third side must be less than 2√34 + 6.

To find the exact length of the third side, we need to check if the triangle inequality is satisfied for an equality. In other words, we need to check if:

2√34 + 6 = x

If this is true, then the given sides can form a triangle.

Simplifying the equation, we get:

x = 2√34 + 6

The exact length is 2√34 + 6 if the triangle inequality is satisfied for an equality.

g(x) = -2√x + 8 is the function that has the same range as f(x) = -2√(x - 3) + 8. Both functions have the range of y ≤ 8

The function that has the same range as f(x) = -2√(x - 3) + 8 is g(x) = -2√x + 8. Both functions have the range of y ≤ 8.There are a few steps involved in determining which function has the same range as f(x) = -2√(x - 3) + 8. The range of a function refers to all the possible output values that the function can produce.Let's begin by examining the original function:f(x) = -2√(x - 3) + 8The square root symbol (√) implies that x-3 must be greater than or equal to 0. If x-3 is negative, then the function would produce an imaginary result.

Let's solve for x when f(x) = 0:0 = -2√(x - 3) + 8-8 = -2√(x - 3)4 = √(x - 3)16 = x - 3x = 19This tells us that the x-value that produces an output of 0 is x = 19. To determine the range, we need to find the maximum and minimum output values. We can use a graphing calculator or sketch a graph to determine the shape of the function and the range.The shape of the function suggests that the range is y ≤ 8, which means that the maximum value of the function is 8. This tells us that any function with the same maximum output value of 8 will have the same range as f(x).
