Question

While in the United States visiting her grandmother, Kendra copied the famous family apple pie recipe. When she returns to England, she plans on making the same apple pie for her friends. To do this, Kendra needs to convert the flour from cups to grams. She knows that 0.5 cup of flour has a mass of 64 grams and 2 cups of flour has a mass of 256 grams.
E. Look at the method you used to evaluate your function in part D. Explain another way you can evaluate the function for the same input.

Answer 1

my function for part D was g(5)=640 and im stuck on E

Answer 2

@kmcllb @undeadknight26 @sammixboo can u guys help to pleeeeeease

Answer 3

@camerondoherty

Answer 4

1 cup = 128
Is this what you need to know?
Or do you need an equation?

Answer 5

this is the question Look at the method you used to evaluate your function in part D. Explain another way you can evaluate the function for the same input. part D my function was g(5)=640

Answer 6

But you see, what am I supposed to be getting?
1 cup? 2 cups? I need to know what they are asking you for.

Answer 7

g(5) = 128 x 5 = g(5) = 640

Answer 8

5 cups

Answer 9

5 cups = 640

Answer 10

256(2) + 1/2(256) = 640

Answer 11

i know but im supposed explain another way you can evaluate the function for the same input.

Answer 12

and im stuck

Answer 13

g(5) = 640
You need another way of saying this?

Answer 14

yes

Answer 15

Do I have to use g(5) = 640 In my equation?

Answer 16

idk

Answer 17

u have to use the same input

Answer 18

Whats the input in g(5) = 640?
5?

Answer 19

yea

Answer 20

Well, let's see here. 128 x 5 Is the only thing that will give you 640.
So just do 128(5) = g

Answer 21

thank you so much can you with another its like this one

Answer 22

Interpret what it means to have g(-2) and determine if this is reasonable given the situation.

Answer 23

I'll give it a try, but may I ask you do the first equation on your own? I'd like you to learn it rather than to "cheat" from me. I may sound like a teacher but I don't mean it like that.

Answer 24

g(-2) 128 x -2 Is very incorrect. therefore leaving this with a NO!

Answer 25

wat do you mean

Answer 26

It's asking you if g(-2) would find you the answer of 640, its a big no! Unless g is -128 which is IMPOSSIBLE to have, -128 grams, is impossible. So 128 * -2 = -256

Answer 27

oh ok

Answer 28

May I ask what grade you're in?

Answer 29

So i would say something like this: Having -2 cups of flour is not reasonable in this situation because it is negative?

Answer 30

oh and 9th grade

Answer 31

Yes, you can't have a negative about of grams, even air was gram weight. The minimum weight is 0. Also give me a GG, I'm in 8th. ;)

Answer 32

wats a GG

Answer 33

Good Game, or a pat on the back.

Answer 34

oh ok i didnt think you were in 8th grade rather i thought you were a teacher

Answer 35

and thx i gave you a medal BTW bye

Answer 36

Haha, no problem, I'm in Algebra II
I'm certified as AIG or Academically Intelligently Gifted.
