The x values of the polynomial expression given as x^2 - 324 = 0 are x = 18 and x = -18
How to factor the polynomial?The polynomial expression is given as:
x^2 - 324 = 0
Rewrite as
x^2 + 0 - 324 = 0
Express 0 as 18x - 18x
So, we have:
x^2 + 18x - 18x - 324 = 0
Factorize the polynomial expression
x(x + 18) - 18(x + 18) = 0
Factor out x + 18
(x - 18)(x + 18) = 0
Split the factors
x - 18 = 0 and x + 18 = 0
Solve for x
x = 18 and x = -18
To use a table, we have
x^2 - 324 = 0
Set x = some values and calculate the expression
x x^2 - 324
3 -315
6 -288
9 -243
18 0
Hence, the values of x are x = 18 and x = -18

The Equation P= 2.5m + 35 represents the price P (in dollars) of a bracelet, where m is the cost of the materials (in dollars). The price of a bracelet is $115. What is the cost of the materials?
Polynomials are algebraic expressions with variables and coefficients.
cost of the materials = (115 - 35) / 2.5 = $77.5
How do you find the number of solutions a polynomial has?Remember from the chapter on Quadratic Functions that every quadratic equation has two solutions. A quadratic equation has a degree of two, which leads us to believe that it has two solutions. The degree will always tell us how many solutions a polynomial has.Polynomials are algebraic expressions with variables and coefficients. Variables are also known as indeterminates. For polynomial expressions, we can perform arithmetic operations such as addition, subtraction, multiplication, and positive integer exponents, but not division by variable.Equation P= 2.5m + 35

In triangle GHJ, Angle G=25°, Angle H=46°, and h=37mm. Determine the length of side g to the nearest millimeter.
The length of side g from the given triangle GHJ to the nearest millimeter is 83 mm.
Given that, in triangle GHJ, ∠G=25°, ∠H=46°, and h = 37 mm.
What is sine rule in triangle?The sine rule of a triangle is sin A/a = sin B/b = sin C/c.
From triangle GHJ
∠G+∠H+∠J = 180°
⇒ 25°+46°+∠J = 180°
⇒ ∠J = 109°
Using sine rule
sin 109°/g = sin 25°/37
⇒ 0.945/g = 0.4226/37
⇒ 34.965 = 0.4226g
⇒ g = 82.73 mm

As an airline pilot, you strive forarrivals that are as close as possible toon-time. When measuring on-timearrivals based on minutes late, do youwant a higher or lower standarddeviation?LowerHigher
The standard deviation measures how far the data are from the dataset mean. The lower the standard deviation is, the closest the data are to the mean.
In this case, the pilot strives for a mean equal to 0 (zero minutes late). Also, since the pilot needs the arrivals to be as close as possible to this mean of zero minutes late (on-time), they want the data of "minutes late" to be all close to this mean. And this is achieved with a lower standard deviation.
Therefore, they want a lower standard deviation.
. Estimate: 186,231 + 88,941
To estimate the sum, we need to round the decimals as:
186,231 ≈ 186
88,941 ≈ 89
So, we sum 186 and 89 as:
186 + 89 = 275
Therefore, the estimated sum of 186,231 + 88,941 is 275
Answer: 275
the tallest living man at one time had a height of cm. the shortest living man at that time had a height of cm. heights of men at that time had a mean of cm and a standard deviation of cm. which of these two men had the height that was more extreme?
Thus here, the height of the tallest person is more extreme as per the z-score.
What is the z-score?
Z-scores let statisticians and traders know whether a score falls within the norm for a given data set or deviates from it.Analysts can also modify scores from multiple data sets using Z-scores to create scores that are more accurately compared to one another.You may determine how many standard deviations you are from the mean by looking at the absolute value. A z-score of zero indicates that a value is on the mean. A Z-Score of +1 indicates that the value is one standard deviation above the mean.Formula for z-score: [tex]\frac{X-\mu }{\sigma }[/tex]
Z-score for the tallest person = {258-176.07}/{7.32}
= 11.1926.
Similarly, Z-score for the shortest person = -7.0587.
The more the absolute value, the more extreme the value.
Thus here, the height of the tallest person is more extreme as per the z-score.

A city's residents voted on whether to raise property taxes. The yes votes outnumbered the no votes 5 to 4. The total number of votes = 1043 if there were 2348 no votes.
What is Ratio and proportion?A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other.
For example, if there is one boy and three girls, the ratio could be written as 1: 3. (for every one boy there are 3 girls). In the ratio, the product of means equals the product of extremes.
If the cross products of two ratios are equal, they are said to be equal. The Proportion Formula is as follows: a: b:: c: d a b = c d
Therefore,
The total number of votes = 1043
yes votes / no votes = 5/4
Means there were a total of 9 votes;
So we could say:
No votes/Total votes = 4/9
So using total of 2348 votes, we can set up a proportion:
No votes/Total votes = 4/9 = x/2348

Based on the definition of complementary angles, the measure of angle CBD is: 68°.
How to Find the Measures of Complementary Angles?If two lines are perpendicular to each other, they form a right angle. In the diagram given, we know that line BA is perpendicular to line BD, therefore the measure of angle ABD would be a right angle = 90°.
Thus, angle CBD and angle ABC are complementary angles because they form a right angle.
Therefore:
The measure of angle CBD + the measure of angle ABC = 90°.
Given:
Measure of angle CBD = 4x + 52
Measure of angle ABC = 8x - 10
Substitute
(4x + 52) + (8x - 10) = 90
Solve for x
4x + 52 + 8x - 10 = 90
Combine like terms
12x + 42 = 90
12x + 42 - 42 = 90 - 42

Imagine that you are given two linear equations in slope-intercept form. You
notice that the slopes are different, but the y-intercepts are the same. How
many solutions would you expect for this system of?
For this system of equations, there will be infinitely many solutions.
Two equations are said to represent a line when they have the same slope and y-intercept. In this instance, one equation is created by adding a constant to the other equation.
Such equations will lay on each other on a graph if we plot them since they represent the same line. We can claim that these equations have an endless number of solutions because every point on that line will satisfy both of the aforementioned equations.
Here's an illustration:
Eq. 1: 2x + y = 4.
4x + 2y Equals 8 in equation 2
The second equation is created by multiplying the previous equation by two, as can be seen if you look at the two equations. The same outcome will be obtained for both if we write them in slope intercept form, as illustrated below:
Equation 1's slope intercept form is y = -2x + 4
Equation 2's slope intercept form is 2y = -4x + 8 and y = -2x + 4
The y-intercept and slope of both equations are identical. Equation 2 applies to any place that satisfies Equation 1. We can therefore draw the conclusion that there are an endless number of solutions to two linear equations with the same slope and y-intercept.
