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]

What are some basic properties of exponentiation?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]
What is the product result of (a+b)(a-b) ?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]

(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.
The length of adult parakeets is normally distributed. If the mean length is 8 inches with a standard deviation of 0.25 inches, what is the probability that a randomly selected adult parakeet will be less than 7.55 inches long?

z = (raw score - mean)/standard deviation
Given that:
Mean = 8 inches, standard deviation = 0.25 in, For < 7.55 in:

Answers
The perimeter of the face PQR is 84 cm.
What is perimeter?The perimeter of an object is the sum of the lengths of the sides of the object.
Given that, there are two similar triangular prisms. Figure 2 is similar to figure 1 by a scale factor of 4.
We know that, the ratio of the perimeters of similar objects is equal to their scale factor.
Therefore,
P(ABC) / P(PQR) = 1/4
21 / P(PQR) = 1/4
P(PQR) = 84
Hence, the perimeter of the face PQR is 84 cm.

DC is the diameter AE is the radiusDB is a chordBC is very short cordSo the series is
DC>DB>AE>BCAnswer:
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
