take square root of 121, which is 11
so -12, 3, 10,
The values that satisfy the inequality x² > 121 are -12 and 13, as their squares are greater than 121.
The question asks which values satisfy the inequality x² > 121. To find the solutions, we need to consider when x² is greater than the square of 11, since 121 is 11². There are two cases:
Case 1: x is greater than 11.
Case 2: x is less than -11.
Now, evaluating the provided options:
A) -12: (-12)² = 144 which is greater than 121. Hence, -12 is a solution.
B) 3: (3)² = 9 which is not greater than 121. Therefore, 3 is not a solution.
C) 13: (13)² = 169 which is greater than 121. Thus, 13 is a solution.
D) 10: (10)² = 100 which is not greater than 121. So, 10 is not a solution.
Therefore, the correct answers that satisfy the given inequality are -12 and 13.
determine whether the question is a statistical question. If it is a statistical question, identify the units for the answer. “How tall is sam?”
Answer:
No
Step-by-step explanation:
Here we are taking only one measurement: the height of one person. Strictly speaking, this is NOT a statistical question.
"List the heights of a sample of 50 first-graders" would definitely be a stat. question.
The question 'How tall is Sam?' is not a statistical question. Statistical questions expect a variety of responses, not a singular answer. Height is typically measured in feet or centimeters.
Explanation:The question 'How tall is Sam?' is not considered a statistical question. A statistical question is one in which the answer varies and requires data collection for multiple items or individuals to answer. It is one for which you don't expect to get a single answer. Instead, you expect to get a variety of different answers, and you're interested in the distribution and tendency of those answers. For instance, 'How tall are the students in a class?' is a statistical question because it would result in a variety of answers and we could analyze that data set.
The unit for height in this context typically is measured in feet or centimeters.

Lynn is a single mother with two children. She qualifies to file as head of household. Her total income before deductions was $38,900 last year. Her total deductions were $11,450. Her employer withheld $3,150 from her pay for tax. Use the tax table below. How much more will Lynn owe in taxes?
To calculate how much more Lynn owes in taxes, we need to subtract her deductions from her total income to find her taxable income, then apply the tax rate from the provided table (which is missing in this case) to determine her tax liability. Unfortunately, without the tax table, we cannot accurately compute her tax obligation or the additional amount owed beyond the $3,150 withheld.
Explanation:The question involves calculating how much more in taxes Lynn will owe after her deductions. Lynn's total income before deductions is $38,900. After subtracting her total deductions of $11,450, her taxable income becomes $27,450. Without the tax table provided in the question, we cannot determine the exact tax rate applicable to Lynn's taxable income nor can we calculate the precise amount of taxes she owes or how much more she will have to pay on top of the $3,150 already withheld by her employer. Typically, to find out how much more Lynn owes, we would apply the appropriate tax rate to her taxable income and then subtract the amount already withheld.
Without specific tax rates and brackets from the tax table, we can only outline the steps to calculate Lynn's tax liability. This scenario underlines the importance of having complete information to accurately determine tax obligations.
The amount Lynn owe in taxes is determined as $399. (Option D).
How to calculate the amount Lynn owe in taxes?
The amount Lynn owe in taxes is calculated by applying the following method as shown below.
Lynn income before tax = $38,900
the total deduction in Lynn income = $11,450
amount withheld for taxes = $3,150
Lynn total income after tax is calculated as;
total income after tax = $38,900 - $11,450
total income after tax = $27,450
From the tax table attached, the tax payable for a head of household earing an income between $27,450 and $27,500 is $3,549.
So if the employer withheld $3,150 for tax, the remaining amount to be paid for tax is;
remaining amount for be paid for tax is calculated as;
= total tax - amount withheld
= $3,549 - $3,150
= $399
Thus, the amount Lynn owe in taxes is $399.
The complete question is below:
Lynn is a single mother with two children. She qualifies to file as head of household. Her total income before deductions was $38,900 last year. Her total deductions were $11,450. Her employer withheld $3,150 from her pay for tax. Use the tax table below. How much more will Lynn owe in taxes?

If sinx=1/9, x in quadrant 1, then find (without finding x):
Sin(2x)=
Cos(2x)=
Tan(2x)=?
Answer:
Part 1) [tex]sin(2x)=8\frac{\sqrt{5}}{81}[/tex]
Part 2) [tex]cos(2x)=\frac{79}{81}[/tex]
Part 3) [tex]tan(2x)=8\frac{\sqrt{5}}{79}[/tex]
Step-by-step explanation:
Part 1) Find sin(2x)
we know that
[tex]sin(2x)=2sin(x)cos(x)[/tex]
we have
[tex]sin(x)=\frac{1}{9}[/tex]
Find cos(x)
Remember that
[tex]sin^{2}(x)+cos^{2}(x)=1[/tex]
substitute
[tex](\frac{1}{9})^{2}+cos^{2}(x)=1[/tex]
[tex]cos^{2}(x)=1-(\frac{1}{9})^{2}[/tex]
[tex]cos^{2}(x)=1-(\frac{1}{81})[/tex]
[tex]cos^{2}(x)=\frac{80}{81}[/tex]
[tex]cos(x)=\frac{\sqrt{80}}{9}[/tex]
[tex]cos(x)=4\frac{\sqrt{5}}{9}[/tex] -----> is positive because angle x belong to the I quadrant
Find sin(2x)
we have
[tex]sin(x)=\frac{1}{9}[/tex]
[tex]cos(x)=4\frac{\sqrt{5}}{9}[/tex]
so
[tex]sin(2x)=2sin(x)cos(x)[/tex]
[tex]sin(2x)=2(\frac{1}{9})(4\frac{\sqrt{5}}{9})[/tex]
[tex]sin(2x)=8\frac{\sqrt{5}}{81}[/tex]
Part 2) Find cos(2x)
we know that
[tex]cos(2x)=cos^{2}(x)-sin^{2}(x)[/tex]
we have
[tex]sin(x)=\frac{1}{9}[/tex]
[tex]cos(x)=4\frac{\sqrt{5}}{9}[/tex]
so
[tex]cos(2x)=(4\frac{\sqrt{5}}{9})^{2}-(\frac{1}{9})^{2}[/tex]
[tex]cos(2x)=\frac{80}{81}-\frac{1}{81}[/tex]
[tex]cos(2x)=\frac{79}{81}[/tex]
Part 3) Find tan(2x)
we know that
[tex]tan(2x)=\frac{sin(2x)}{cos(2x)}[/tex]
we have
[tex]sin(2x)=8\frac{\sqrt{5}}{81}[/tex]
[tex]cos(2x)=\frac{79}{81}[/tex]
so
[tex]tan(2x)=\frac{8\frac{\sqrt{5}}{81}}{\frac{79}{81}}[/tex]
[tex]tan(2x)=8\frac{\sqrt{5}}{79}[/tex]
Using trigonometric identity functions, when Sinx equals 1/9, Sin(2x) equals 2√80/729, Cos(2x) equals 79/81, and Tan(2x) equals 162√80/56831.
Explanation:The question asks for the values of Sin(2x), Cos(2x), and Tan(2x) when Sinx = 1/9 (x in Quadrant 1). To solve for these values, we can use the identity formulas. If given that sinx = 1/9, it follows that cosx = √(1 - sin²x) = √(1 - (1/81)) = √(80/81) because in quadrant 1, the cosine value is positive. Therefore:
Sin(2x) = 2sinxcosx = 2 * 1/9 * √80/81 = 2√80/729,Cos(2x) = cos²x - sin²x = (80/81 - 1/81) = 79/81,Tan(2x) = sin(2x)/cos(2x)= (2√80/729) / (79/81) = 162√80/56831Learn more about Trigonometry here:https://brainly.com/question/11016599

Step-by-step explanation:
given
2x² - 5x - 3 = 0 ← in standard form
To factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 3 = - 6 and sum = - 5
The factors are - 6 and + 1
Use these factors to split the x- term
2x² - 6x + x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(x - 3) + 1(x - 3) = 0 ← factor out (x - 3)
(x - 3)(2x + 1) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - [tex]\frac{1}{2}[/tex]
What is the length of segment LM
Answer:
LM = 23 units
Step-by-step explanation:
triangle KLN and triangle MLN are congruent.
The segment LM is equal to segment LK.
Also, MN is same as KN, thus we can write:
[tex]MN=KN\\25=14x-3\\25+3=14x\\28=14x\\x=2[/tex]
Since, x = 2, we can get the side length LM:
[tex]LM=LK=9x+5\\LM=LK=9(2)+5\\LM=23[/tex]
Hence, LM = 23 units
Answer:
LM = 23 units
Step-by-step explanation:
From figure we can see an isosceles triangle KNM
KN = NM
NL is the perpendicular from N to KM,
Therefore KL = LM
To find the value of x
From figure we can write,
14x - 3 = 25
14x = 25 + 3 = 28
x = 28/14 = 2
To find LM
LM = KL
we have KL = 9x + 5
Therefore LM = 9x + 5 = (9 * 2) + 5 = 23 units

If a rectangular prism with a length of 12 feet and a width of 9 feet has a surface area of 930 square feet find its height
Answer:
The height is 17 ft
Step-by-step explanation:
The surface area of a rectangular prism is
SA = 2(LW +WH + LH)
where L = length, W = width, and H = height
We know SA = 930, L = 12, and W = 9
930 = 2(12*9 +9H + 12H)
Divide each side by 2
930/2 = 2/2(12*9 +9H + 12H)
465 = (12*9 +9H + 12H)
Combine like terms
465 = 84+21H
Subtract 84 from each side
465-84 = 84-84+21H
357 = 21H
Divide by 21
357/21=21H/21
17 = H
The height is 17 ft
Answer:
Height is 17 ft.
Step-by-step explanation:
Given: Rectangular Prism is also called cuboid
Length, L = 12 ft. and width, W = 9 ft.
Surface Area of cuboid, SA = 930 ft.²
To find: height , H
The surface area of a rectangular prism or cuboid
SA = 2(LW +WH + LH)
930 = 2(12×9 +9H + 12H)
[tex]\frac{930}{2}=108 +9H + 12H[/tex]
465 = 108 + 9H + 12H
108 + 9H + 12H = 465
21H + 108 = 465
21H = 465 - 108
21H = 357
[tex]H=\farc{357}{21}[/tex]
H = 17
therefore, Height is 17 ft.

Parallelogram: A quadrilateral with opposite sides that are both parallel and equal in length. Opposite angles are equal, and adjacent angles are supplementary.Rhombus: A type of parallelogram where all four sides are of equal length. Additionally, the diagonals of a rhombus are perpendicular and bisect each other at right angles.Given these definitions, let's evaluate each statement:
A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not.Option A) is the true statement as rhombuses always have four equal sides and parallelograms sometimes do not.
what is the sum of the sequence 152,138,124, ... if there are 24 terms?
Answer: -216
Step-by-step explanation:
To solve the exercise you must use the formula shown below:
[tex]Sn=\frac{(a_1+a_n)n}{2}[/tex]
Where:
[tex]a_1=152\\a_n=a_{24}[/tex]
You should find [tex]a_{24}[/tex]
The formula to find it is:
[tex]a_n=a_1+(n-1)d[/tex]
Where d is the difference between two consecutive terms.
[tex]d=138-152=-14[/tex]
Then:
[tex]a_{24}=152+(24-1)(14)=-170[/tex]
Substitute it into the first formula. Therefore, you obtain:
[tex]S_{24}=\frac{(152-170)(24)}{2}=-216[/tex]
Answer:
Sn = -216
Step-by-step explanation:
We are given the following sequence and we are to find the sum of the given sequence if there are 24 terms in it:
[tex] 152, 138, 124, ... [/tex]
We know that the formula of sum for an arithmetic sequence is given by:
[tex]S_n =\frac{n(a_1+a_n)}{2}[/tex]
where [tex]a_1[/tex] is the first term (124)and [tex]a_n[/tex] is the last term [tex]a_{24}[/tex].
To find [tex]a_1[/tex], we will use the following formual:
[tex]a_n=a_1+(n-1)d[/tex]
[tex]a_24=152+(24-1)(-14)[/tex]
[tex]a_{24}=170[/tex]
Substituting the given values in the above formula to get the sum:
[tex]S_n =\frac{24(152-170)}{2}[/tex]
[tex]S_n=-216[/tex]

Option (A) The correct equation that represents 'three times the sum of a number and eight is forty-five' is 3(n+8)=45.
The equation representing "three times the sum of a number and eight is forty-five" is 3(n+8)=45. This is derived by translating the sentence into a mathematical expression: 'three times' corresponds to multiplication by 3, 'the sum of a number and eight' translates to the expression (n+8), where 'n' is the unknown number. Lastly, 'is forty-five' establishes the equality to 45.
Indicate in standard form the equation of the line passing through the given points. M(0, 6), N(6, 0)
ANSWER
[tex]x + y = 6[/tex]
EXPLANATION
Given the x- intercept: (a,0)
and the y-intercept : (0,b)
The equation in standard form is given by:
[tex] \frac{x}{a} + \frac{y}{b} = 1[/tex]
The given x-intercept is N(6,0) and y-intercept is M(0,6).
This implies that:
a=6, and b=6.
We substitute into the formula to obtain:
[tex]\frac{x}{6} + \frac{y}{6} = 1[/tex]
Multiply through by 6 to get the standard form of the equation as:
[tex]x + y = 6[/tex]
