Answer:
Step-by-step explanation:
The slope of a line perpendicular to a given line is the negative reciprocal of the slope of the given line. To find the slope of the line x - 6y = 24, we can rearrange the equation to the form y = (1/6)x + 4. So the slope of the line is 1/6.
The slope of a line perpendicular to this line would be the negative reciprocal of 1/6 which is -6

What is area of circle ?
area of circle can be defined as the product of pi and square of radius of a circle.
We know that the length of tangents which are drawn from an external point are equal.
PA = PB
The tangent at any point on the circle is perpendicular to the radius of the circle through the point of contact.
OB ⊥ PB and OA ⊥ PA
∠PBO = 90°, ∠PAO = 90°
The sum of all the angles in a quadrilateral is 360°.
In the quadrilateral PAOB
∠APB + ∠PAO + ∠PBO + ∠AOB = 360°
43° + 90° + 90° + ∠AOB = 360°
∠AOB = 360° - 223°
∠AOB = 137°
Therefore, the angle measure indicated is 137°.

Considering the given figure, with circumcenter at N. The dimensions are solved to be
HN = 130
LJ = 126
GJ = 168
How to find the unknown dimensions of the figureThe unknown dimensions is calculated as follows
Solving for HN
Considering the problem, the hypotenuse of each of the right triangles are equal
HN = GN = JN = 130
Solving for LJ using Pythagoras theorem.
the formula of the theorem is
hypotenuse² = opposite² + adjacent²
JN² = LN² + LJ²
130² = 32² + LJ²
LJ² = 130² - 32²
LJ² = 15876
LJ = √15876
LJ = 126
solving for GJ
GK + KJ = GJ
GK = KJ - angle bisector theorem
GK + GK = GJ
2GK = GJ

In order to summarize qualitative data, a useful tool is a frequency distribution.
Frequency distribution is a table or graph that shows the number of occurrences of each unique value or range of values in a dataset. It is a way of summarizing and organizing a set of data by grouping them into mutually exclusive classes or bins and counting the number of observations in each class. The resulting table or graph is called a frequency table or frequency distribution. The classes or bins are often defined based on the scale of measurement of the variable, such as intervals for continuous variables or categories for categorical variables. Frequency distribution is a useful tool for understanding the distribution of a variable and identifying patterns or outliers in the data.

How many real fifth roots does 1 have?
1 have only one real fifth root.And the root is 1
What is fifth root?The fifth root of a number is the number that would have to be multiplied by itself 5 times to get the original number. For example, the fifth root of 243 is 3 as 3 x 3 x 3 x 3 x 3 is 243. Another example is fifth root of 32 which is 2. i.e 2×2×2×2×2 = 32
Unlike the even roots like square root fourth root and 6 root that has 2 real roots as solutions, e.g fourth root of 256 is ± 4. This mean multiplying -4 in four places and + 4 in four places will give 256, odd roots like fifth root, cube root only have one root.
The fifth root of 1 is 1.i.e 1×1×1×1×1 = 1

Answer: R(-6.5, 2)
Step-by-step explanation:
Given: M(-1,-3) Q(4.5, -8) R(x,y)=?
The coordinates of the point in the middle of the segment are equal to the arithmetic mean of the coordinates of its ends
[tex]\displaystyle\\Hence,\ x_M=\frac{x_Q+x_R}{2}\\\\-1=\frac{4.5+x_R}{2} \\[/tex]

Deeni bought 1000 units of stock at a price of RM 2.50 per unit. he sold all the shares at a price of rm 3.10 per unit. calculate the profit obtained
Answer:
RM 600
Step-by-step explanation:
1 unit -> bought for RM 2.50
sold for RM 3.10
Selling price is higher than buying price, hence a profit is made.
Profit (for 1 unit) = Selling price - Buying Price
= RM 3.10 - RM 2.50
= RM 0.60
Since Deeni bought 1000 units of stock,
Profit Obtained = 1000 x RM 0.60
= RM 600
Sue has 2 cats.
Each cat eats 1/4 of a tin of cat food each day.
Sue buys 8 tins of cat food.
Has Sue bought enough cat food to feed her 2 cats for 14 days?
You must show how you get your answer.
Answer:
She has bought enough.
Step-by-step explanation:
Sue's 2 cats eat a total of
Cats * Eat a Day = Daily
2 * 1/4 = 1/2
tins of cat food per day. Therefore, they will eat a total of
Daily * Day = Total Needed
1/2 * 14 = 7
tins of cat food in 14 days. Since Sue has bought 8 tins of cat food, she has bought enough to feed her 2 cats for 14 days.
yes she has bought enough food to feed her cats for 14 days
if one cats eats 1/4 can each day then it will b 2/4 for one whole day for 2 cats
2/4 cans x 14 days
1 can lasts for 2 days
so 7 cans last for 14 days
Wayne just became a personal trainer and is finalizing his pricing plans. One plan is to charge $9 for the initial consultation and then $68 per session. Another plan is to charge $75 for the consultation and $65 per session. Wayne realizes that the two plans have the same cost for a certain number of sessions. How many sessions is that? What is that cost?
The number of sessions when the plans would cost the same is 22. The cost of the plan is $1,505.
When would the sessions cost the same?The linear equations that represent the total cost of using a personal trainer would have this form:
consultation fee + (cost per session x number of sessions)
The linear equation that represents the first plan : $9 + ($68 x s)
= $9 + $68x
The linear equation that represents the second plan : $75 + ($65 x s)
= $75 + $65s
When the two plans have the same cost, the two above equations would be equal
$75 + $65s = $9 + $68s
In order to determine the value of s, take the following steps:
Combine similar terms together : $75 - $9 = $68s - $65s
Add similar terms together: $66 = $3s
Divide both sides of the equation by $3
s = $66 / 3
s = 22
Cost when the two plans have the same cost = $9 + (22 x 68)
= $9 + 1496
= $1,505

Time series data is a set of data points collected at regular intervals of time. It is used to track changes in a certain variable over time, and can be used to analyze trends, patterns, and predictions about future events.
Time series data is often collected in fields such as finance, economics, and statistics, and can be used for tasks such as forecasting stock prices, understanding economic indicators, and analyzing sensor data.
It is important to note that time series data is different from cross-sectional data, which is a snapshot of data collected at a single point in time.
Time series data can be analyzed using statistical and machine learning techniques such as time series decomposition, ARIMA, and LSTM to extract meaningful insights and make accurate predictions. Time series data can also be visualized using line plots, bar plots, and heat maps to help identify trends and patterns in the data.

The surface area of the triangular prisms are:
1. 116 cm²
2. 82 cm².
How to Find the Surface Area of a Triangular Prism?To find the surface area of the triangular prism, add the areas of all the faces or shapes that make up the net of the triangular prism.
Problem 1: The triangular prism net consists of 2 identical rectangles, 2 identical triangles and 1 different rectangle.
Area of rectangle = length * width
Area of triangle = 1/2(base * height)
Therefore:
Area of the two identical rectangles = 2(7 * 4) = 56 cm²
Area of the larger rectangle = 6 * 7 = 42 cm²
Area of the two identical triangles = (6 * 3) = 18 cm²
The surface area= 56 + 42 + 18 = 116 cm²
Problem 2:
Area of the rectangle 1 = 6 * 3 = 18 cm²
Area of the rectangle 2 = 6 * 4 = 24 cm²
Area of the rectangle 3 = 6 * 5 = 30 cm²
Area of the two identical triangles = (5 * 2) = 10 cm²

Find the equation of the line that passes through the point (-4, 15) and is perpendicular to y = -2x - 9.
In this case, y1 = 15 and x1 = -4. Substituting these values into the point-slope form, we get: y - 15 = 2(x - (-4)) , Simplifying, we get: y = 2x + 21
y = 2x + 21
To find the equation of the line that passes through the point (-4, 15) and is perpendicular to y = -2x - 9, we can use the slope formula.
The slope of the line y = -2x - 9 is m = -2. The slope of a perpendicular line is the negative reciprocal of m, or m = 2.
We can use the point-slope form of a line to find the equation of the line. The point-slope form of a line is y - y1 = m(x - x1).
In this case, y1 = 15 and x1 = -4. Substituting these values into the point-slope form, we get:

Volume of 19.6 g of a liquid that has a density of 0.967 g/ml is 20.3
Volume and density are connected by a particular substance's mass. The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d).
Density decreases when volume increases without accompanying increases in mass.
here,
Density = mass/volume
or, Volume = mass/density
or, volume = 1.96g/0.967 g/ml
or, volume = 20.268 ml (nearly equal to 20.3)
