which of the following would result in the same value as -40 divided by 2? select all that apply

The factors of the expression specified is given by: Option B: [tex](2x^2 - 1)(2x^2 + 1)(4x^4 + 1)[/tex]

If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c[/tex]

Suppose two numbers are there as 'a' and 'b'.

Then, we get:

[tex](a+b)(a-b) = a(a-b) + b(a-b) = a^2 -ab + ab - b^2 = a^2 - b^2\\(a+b)(a-b) = a^2 - b^2[/tex]

For the considered case, factoring the considered expression [tex]16x^8 - 1[/tex] by rewriting it as:

[tex]16x^8 - 1 = (4 \times 4 \times x^4 \times x^4) - 1^2 = (4x^4)^2 -1^2\\\\\\[/tex]

Now, since we've got [tex](a+b)(a-b) = a^2 - b^2[/tex], therefore,

[tex]16x^8 - 1 = (4x^4)^2 -1^2\\16x^8 - 1 = (4x^4 +1 )(4x^4 - 1)[/tex]

The second term can also be factored using same property, as shown below:

[tex]16x^8 - 1 = (4x^4 +1 )(4x^4 - 1) = (4x^4 + 1)((2x^2)^2 - 1^2) \\16x^8 - 1 = (4x^4 + 1)(2x^2 + 1)(2x^2 - 1)\\\\\text{Rearranging the terms, we get}\\16x^8 - 1 = (2x^2 - 1)(2x^2 + 1)(4x^4 + 1)[/tex]

Therefore, the factors of the expression specified is given by: Option B: [tex](2x^2 - 1)(2x^2 + 1)(4x^4 + 1)[/tex]

Answer:

Option B

Step-by-step explanation:

I took the test.

Answer:

(x - 7)² = 9

Step-by-step explanation:

x² - 14x + 40 = 0 ( subtract 40 from both sides )

x² - 14x = - 40

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 7)x + 49 = - 40 + 49

(x - 7)² = 9

Answer:

[tex]\sf (x-\boxed{\bf7}\:)^2=\boxed{\bf9}[/tex]

Step-by-step explanation:

First of all, let's move the constant term to the right side of the equation:-

[tex]\sf x^{2} -14=-40[/tex]

To complete the square we'll take half of the coefficient of our x term, square it, and add it to both sides of the equation. Since the coefficient of our x term is -14 ,half of it would be -7 and squaring it gives us 49.

[tex]\sf x^2-14x+49=-40+49[/tex]

Now, we can rewrite the left side of the equation as a squared term.

[tex]\sf (x-7)^2=9[/tex]

Step-by-step explanation:

bc 9315/7 is a decimal so u round up

The equation has one solution and it is x = 91/30

Let's take a glimpse at the solution

[tex]6 + 9( - 3x + 9) = \frac{3}{2} (2x + 4) - 10[/tex]

[tex]6 - 27x + 81 = \frac{3}{2} \times 2(x + 2) - 10[/tex]

[tex]6 - 27x + 81 = 3(x + 2) - 10[/tex]

[tex]6 - 27x + 81 = 3x + 6 - 10[/tex]

[tex] - 27x + 81 = 3x - 10[/tex]

[tex] - 27x - 3x = - 10 - 81[/tex]

[tex] - 30x = - 91[/tex]

Answer:

DC

Step-by-step explanation:

So the series is

Answer:

b.  DC

b.  15

Step-by-step explanation:

Point A = center of circle

The widest part of the circle is the diameter.  The diameter is a straight line that touches the circumference of the circle and passes through the center of the circle. Therefore, the diameter is DC, and this is the longest line segment.

The radius of a circle is a straight line from the center of the circle to a point on the circumference.  Therefore, AE = radius of the circle.

The radius of a circle is half the length of the diameter.

Therefore, if AE = 7.5, then DC = 2 × 7.5 = 15

Answer:

12^15

Step-by-step explanation:

(12^2)^7 would be 12^14 because the two exponents (2 and 7) will multiply each other. Then, you do 12^14 * 12, which would be 12^15 because you are multiplying 12 by itself one more time.

There is a probability of 3.95% that the randomly selected adult parakeet will be less than 7.55 inches long

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean)/standard deviation

Given that:

Mean = 8 inches, standard deviation = 0.25 in, For < 7.55 in:

z = (7.55 - 8) / 0.25 = -1.8

P(z < -1/8) = 0.0395

The number of senior, adults and children tickets sold are 22, 76 and 66 respectively.

The museum sells three types of tickets, including those for seniors, adults and children.

On Tuesday morning the  museum sold 164 tickets. Therefore,

Let

x = number of senior ticket sold.

The number of adult tickets sold was three times as many as senior tickets sold.

The number of child tickets sold was 10 more than the number of adult tickets sold. Therefore,

Total ticket sold = 3x + 10 + 3x + x

164 = 7x + 10

154 = 7x

x = 154 / 7

x = 22

Therefore,

number of senior ticket sold = 22

number of adult tickets sold = 3 (22) = 66

number of child tickets sold = 10 + 3(22) = 76
