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

Answer 1

Answer:

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)

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.
