Help Please...So, I'm doing a blueprint assignment for my school. I have to determine a scale factor. Right now, the house is in feet, its measurements 20 by 40. I want to do a blue print using centimeters as my scale. What I want to do is scale factor it so it's not too small but at the same time doesn't take up the whole graph paper. If anyone has a idea on what scale factor I should use, please answer.

Karen bakes cookies. She has observed that the number of cookies that turn out well in each batch varies with the size of the batch and is given by the function f(x) = 2x – 23, where x is the size of the batch (number of cookies in each batch). She never bakes fewer than 12 cookies in a batch. If the size of five batches is {20, 25, 26, 27, 34}, how many cookies turn out well in each batch?Answers Choices
{17, 27, 29, 31, 45}
{18, 24, 26, 30, 46}
{14, 23, 25, 31, 42}
{20, 24, 25, 26, 44

Answers

Substitute the values of the size of the 5 batches to the model.

For example

@x = 20

f(20) = 2*20 – 23 = 17

f(25) = 2*25 – 23 = 27

f(26) =29

f(27) = 31

f(34) = 45

 

Therefore the answer is the first choice (17, 27, 29, 31, 42)

4/3v^2x -5/6vx^3 what is this answer for algebra

Answers

(4)/(3) v^2x -  (5)/(6) vx^3

(4)/(3) v^2x +  (-5)/(6) vx^3

Answer: (-5)/(6) vx^3 + (4)/(3) v^2x
(4)/(3v^(2)x) - (5)/(6vx^(3)) = (5(3v^(2)x))/((3v^(2)x)(6vx^(3))) - (4(6vx^(3)))/((3v^(2)x)(6vx^(3))) = (15v^(2)x)/(18v^(3)x^(4)) - (24vx^(3))/(18v^(3)x^(4)) = (15v^(2)x - 24vx^(3))/(18v^3x^(4)) = (5v)/(6x^(2)) - (4)/(3v^(2)x)

Answer:

f(x)=24

Step-by-step explanation:

Replace x in the function with the value 4.

f(4)= (4)^2 + 3(4) - 4  

16 + 12 -4

The table below shows the distance y, in miles, traveled by a toy car in x minutes:Time (x)
(minutes) 20 30 40 50
Distance (y)
(miles) 5 10 15 20


Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and distance traveled by the toy car. (4 points)
[Choose the value of correlation coefficient from 1, 0.8, 0.5, 0.02]

Part B: What is the value of the slope of the graph of distance versus time, and what does the slope represent? (3 points)

Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)

Answers

Part A: The correlation coefficient is 1. It means that the values of both x and y has a strong relationship giving them a avalue of 1.

Part B: The value of the slope of the graph is 0.5. the slope of the line represents how steep is the line of your graph

Part C: The data presented is correlation.
