The complete factored form of the quadratic expression is (x-8y)(x-8y)
Factorizing quadratic expressionQuadratic expressions are expressions that has a leading degree of 2
Given the expression
x^2 – 16xy + 64y^2
Factorize
x^2 - 8xy - 8xy + 64y^2
Group
(x^2 - 8xy) - (8xy + 64y^2)
x(x-8y) - 8y(x - 8y)
Since (x-8y) is common, hence;
x^2 - 8xy - 8xy + 64y^2 = (x-8y)(x-8y)
The complete factored form of the quadratic expression is (x-8y)(x-8y)

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. Using the empirical rule, determine the interval that would represent the middle 99. 7% of IQ scores
Answer:
The interval that would represent the middle 99.7% of IQ scores is (55, 145).
Step-by-step explanation:
The empirical rule tells us that 68% of values are within one standard deviation from the mean, 95% of values are within two standard deviations from the mean, and 99.7% of values are within three standard deviations from the mean.
If we want to determine the interval representing the middle 99.7% of IQ scores, we need to determine the values that are three standard deviations from the mean.
We are given the standard deviation of 15 and a mean of 100. Three standard deviations from the mean can be calculated as such:
100 - 15(3) < 100 < 100 + 15(3)100 - 45 < 100 < 100 + 4555 < 100 < 145The interval that represents the middle 99.7% of IQ scores is (55, 145).

The arc measure of the arc BC is 155°.
What is the arc measure of an arc of a circle in degrees?A complete circle has an arc, that is, a central angle of 360°. whose sum of angles is shown below:
AD + AB + BC + CD = 360°
Where AD = 155°
Since the four angles are generated by two diameters, then we find that AD = BC and AB = CD. Hence:
2 · AD + 2 · AB = 360 Given
AD + AB = 180 Compatibility with multiplication / Existence of the multiplicative inverse / Modulative property
AB = 180 - AD Compatibility with addition / Existence of the additive inverse / Modulative property
AB = 180 - 155 Given
AB = 25 Definition of subtraction / Result
Then, the arc measure of the arc BC is 155°.

(1, ∞)
(∞, ∞)
Both functions g(x) and f(x) are positive in the interval of (1, ∞). Then the correct option is C.
What is the domain and range of a function?The domain is the set of values for which the given function is defined.
The range is the set of all values which the given function can output.
When comparing the f(x) = x² – x and g(x) = log(2x + 1).
For f(x), we have
f(x) = x² – x
f(x) = x² – x + 1/4 - 1/4
f(x) = (x - 1/2)² - 1/4
The domain and the range of the function f(x) will be (-∞, ∞) and (-5, ∞).
For g(x), we have
g(x) = log(2x + 1)
The domain and the range of the function g(x) will be (-1/2, ∞) and (-∞, ∞).
Both functions g(x) and f(x) are positive in the interval of (1, ∞). Then the correct option is C.

Answer:
∠BIF = 126°
∠JBC = 63°
∠BJD = 117°
Step-by-step explanation:
adjacent angles in a rhombus add up to 180°
∠IBJ and ∠BIF are adjacent angles in a rhombus
thus,
∠IBJ + ∠BIF = 180°
54° + ∠BIF = 180
subtract 54 from both sides to isolate the variable
∠BIF = 126°
a line is 180°
thus, ∠IBA + ∠IBJ + ∠JBC = 180° as those three angles form a line
as the parallelograms are congruent, and we can visually notice that ∠IBA corresponds to angle ∠JBC, we can say that ∠IBA = ∠JBC
thus,
∠IBA + ∠IBJ + ∠JBC = 180°
54° + ∠JBC + ∠JBC = 180°
54° + 2∠JBC = 180
subtract 54 from both sides to isolate the variable and its coefficient
126° = 2∠JBC
divide 2 from both sides to isolate the variable
∠JBC = 63°
adjacent angles in a parallelogram add up to 180°
∠JBC and ∠BJD are adjacent angles in a parallelogram
∠JBC + ∠BJD = 180°
63° + ∠BJD = 180°
subtract 63 from both sides to isolate the variable
∠BJD = 117°

75°
x + 75 = 90
2x + 75-90
x + 75 - 180
2x + 75 = 180
Answer:
D. 2x+75=180Step-by-step explanation:
Given:
This figure gives us 180 degrees of angles.
Calculate the angle of x in the figures according to the term x on one side of the equation.
The angle relationship should be represented by 2x.
2x+75=180
First, subtract by 75 from both sides.
2x+75-75=180-75
Solve.
Subtract the numbers from left to right.
180-75=105
2x=105
Divide by 2 from both sides.
2x/2=105/2
Solve.
Divide the numbers from left to right.
105/2=52.5
x=105/2=52.5
Therefore, the correct answer is "D. 2x+75=180".I hope this helps. Let me know if you have any questions.

Mr. Porter’s grocery bill is $143.74. If 5.3% sales tax is added to his bill, what is the total Mr. Porter owes?
A:7 dollars and 62 cents
B:149 dollars and 4 cents
C:136 dollars and 12 cents
D:151 dollars and 36 cents
Answer:
D
Step-by-step explanation:
100% = $143.74
1% = 100%/100 = 143.74/100 = $1.4374
5.3% = 1%×5.3 = 1.4374 × 5.3 = $7.61822
$143.74 + 5.3% = $143.74 + $7.61822
or
105.3% of $143.74 = 143.74 × 1.053 = 151.35822 ≈
≈ $151.36
