Which of the following equations contains the point (8,5) and is perpendicular to the line y=2x-3
Answer:
y = - [tex]\frac{1}{2}[/tex] x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 3 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex], thus
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (8, 5) into the partial equation
5 = - 4 + c ⇒ c = 5 + 4 = 9
y = - [tex]\frac{1}{2}[/tex] x + 9 ← equation of line

Joe needs to replace the carpet in his living room and hallway with hardwood flooring. A floor plan is shown below. what is the total area of the floor plan? Each box of flooring contains 2.05 square meters of flooring. How many boxes should Joe buy? One box costs $54.80. How much will the flooring cost?If Joe gets a coupon for 20% off, how much would the flooring cost?
Answer:
A. Area total= 30 m2
B. 14 boxes
C. 596.40
D. 477.12
Step-by-step explanation:
A, 3.2 (1.5) A=4.8 A=6(4.2)= 30m2
B= 30/2.5= 13.95= 14 boxes
C. 12(42.6)= 596.40
D= 80/100= x/596.4 = 477.12
The total area Joe needs to cover with hardwood flooring would determine the number of boxes of flooring he should buy. Assuming the area is 100 square meters, Joe would need 49 boxes, which would cost $2,685.20 without a discount, and $2,148.16 after a 20% discount.
To determine the total area that Joe needs to floor and the number of boxes of flooring he should buy, we need to calculate the square meters of the combined living room and hallway. Unfortunately, the floor plan measurements are not provided in the question, so let's assume we have those measurements. For example, if the living room and hallway together are 100 square meters, Joe will divide the total area by the area covered by one box of flooring to find out how many boxes he needs.
The calculation for the number of boxes is as follows: total area divided by area per box. If each box contains 2.05 square meters of flooring, and the total area is 100 square meters, Joe would need 48.78 boxes. Since he can't buy a fraction of a box, he would need to purchase 49 boxes.
To find the total cost, we multiply the number of boxes by the cost per box. At $54.80 per box, the cost for 49 boxes is $2,685.20. With a 20 percent discount, the new cost is 80 percent of the original cost, which would be $2,148.16 (0.80 x 2,685.20).

a mountain bike tire has a diameter of 26 inches to the nearest foot how far does the tire travel when it makes 32 revolutions and does this require circumference and area?
The distance it covers in 32 revolution is 217.9 ft .
Step-by-step explanation:
Given,
The diameter of the tire of the bike = 26 in
The radius (r) = 13 in
To find the distance it travels in 32 revolutions.
To find the revolution we need to find the circumference.
Formula
The circumference of a circle = 2πr
Now,
The circumference of a circle = 2×[tex]\frac{22}{7}[/tex]×13 in
= 81.71 in (approx)
The distance it covers in 32 revolution is = 81.71×32 in
= 2614.85 in
We know that 1 ft = 12 inch
2614.85 in = 2614.85 ÷ 12 ft = 217.9 ft (approx)
what is the volume of this right triangular pyramid?
Answer:
2736
Step-by-step explanation:
Formula is 1/3 x base area x height
The volume of the right triangular pyramid is [tex]\(2736 \text{ cm}^3\).[/tex] Therefore, option a is correct.
To find the volume of a right triangular pyramid, you can use the formula:
[tex]\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]
The base area of a right triangular pyramid is given by the formula for the area of a triangle:
[tex]\[ \text{Base Area} = \frac{1}{2} \times \text{Base} \times \text{Height} \][/tex]
Given the dimensions of the right triangular pyramid as [tex]\(36 \text{ cm}\), \(19 \text{ cm}\), and \(24 \text{ cm}\), we have:[/tex]
Base:[tex]\(19 \text{ cm}\)[/tex]
Height of the triangle: [tex]\(36 \text{ cm}\)[/tex]
Height of the pyramid: [tex]\(24 \text{ cm}\)[/tex]
First, let's find the base area:
[tex]\[ \text{Base Area} = \frac{1}{2} \times \text{Base} \times \text{Height} = \frac{1}{2} \times 19 \times 36 \]\[ \text{Base Area} = \frac{1}{2} \times 19 \times 36 = 342 \text{ cm}^2 \][/tex]
Now, let's calculate the volume of the pyramid:
[tex]\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} = \frac{1}{3} \times 342 \times 24 \][/tex]
[tex]\[ V = \frac{1}{3} \times 342 \times 24 = 2736 \text{ cm}^3 \][/tex]
So, the volume of the right triangular pyramid is [tex]\(2736 \text{ cm}^3\).[/tex]
From the table below, determine whether the data shows an exponential function. Explain why or why not
1 x 1 3 6 9 12
1 y 1 1 1 2 4 1 8
a. No, the domain values are at regular intervals.
b. No; a different value is added to each range value.
C. No; there is no relationship between the x value and its corresponding y value.
d. Yes; the domain values are at regular intervals and the range values have a common factor 2
Please select the best answer from the choices provided
Final answer:
The data provided do not represent an exponential function, as there is no constant ratio between y-values for evenly spaced x-values. The correct answer among the given options is 'c' suggesting there is no clear relationship between the x and y values.
Explanation:
From the provided data, it is not clear whether there is an exponential relationship between the x and y values. To determine whether a set of data represents an exponential function, we typically look for a constant ratio between successive y-values when the x-values are evenly spaced. In other words, as x increases by regular intervals, the y values should be multiplied by a constant factor if the relationship is exponential. However, the y-values listed (1, 1, 1, 2, 4, 1, 8) do not show a common factor between each term. Therefore, the data do not represent an exponential relationship, making option 'd' incorrect.
Let's evaluate the other options:
a. No, the domain values are at regular intervals: This is a characteristic of an exponential function, but the range values must also have a common factor, which they do not in this case.
b. No; a different value is added to each range value: This could suggest a linear or polynomial relationship rather than an exponential one. However, without additional context or a pattern in the additions, we cannot be certain of this either.
c. No; there is no relationship between the x value and its corresponding y value: Based on the erratic pattern of y-values, this option seems the most accurate as it suggests that the data does not correspond to any clear mathematical relationship.
The best choice given the options is likely 'c' as it accurately describes the lack of consistent relationship between x and y values necessary for a function to be exponential.

There are 10 pens and 15 pencils in a box. If a student selects two of them at random,
then what is the probability of selecting a pen and then a pencil?
Answer:
0.25
Step-by-step explanation:
Given:
Number of pens in a box = 10
Number of pencils in a box = 15
To find: probability of selecting a pen and then a pencil
Solution:
Probability refers to the chance of occurring of some event.
Probability of selecting a pen and then a pencil = (Probability of selecting a pen) × (Probability of selecting a pencil given that a pen has already been drawn)
[tex]=\frac{10}{25}\times \frac{15}{24}=\frac{150}{600}=\frac{1}{4}=0.25[/tex]
Probabilities are used to determine the chances of events
The probability of selecting a pen and then a pencil is 1/4
The samples are given as:
[tex]Pen = 10[/tex]
[tex]Pencil = 15[/tex]
The total number of items in the box is:
[tex]Box = 10 + 15[/tex]
[tex]Box = 25[/tex]
The required probability is then calculated as:
P = P(Pen) * P(Pencil)
So, we have:
[tex]P =\frac{10}{25} \times \frac{15}{24}[/tex]
Evaluate the product
[tex]P =\frac{150}{600}[/tex]
Simplify
[tex]P =\frac{1}{4}[/tex]
Hence, the required probability is 1/4

Rewrite the equation in Ax+By=C form.
Use integers for A, B, and C.
y+6=-6(x+1)
Answer:
-6x+y=0
Step-by-step explanation:
y+6=-6(x+1)
y+6=-6x-6
-6x+y=0
On converting y + 6 = -6(x + 1) to Ax+By=C form, get 6x + y = -6 with A=6, B=1, and C=-6.
To rewrite the equation y + 6 = -6(x + 1) in the Ax+By=C form, where A, B, and C are integers, we need to distribute the -6 and then move all terms involving variables to one side of the equation and the constant term to the other side.
First, distribute the -6:
y + 6 = -6x - 6
Now, move the variable terms to one side by adding 6x to both sides:
6x + y + 6 = 0
Finally, subtract 6 from both sides to isolate the constant:
6x + y = -6
Now the equation is in the desired format with A=6, B=1, and C=-6.
