Question

Patricia has two plants in her garden. Plant A grows 2 inches per month and Plant B grows 1.8 meters in a year.

[1 meter = 39.37 inches]

Part A: Which plant grows faster? Justify your answer by comparing the rate at which the plants grow after converting to the same units. (5 points)

Part B: If the original height of the plant was 2 inches, and you checked on its height every 15 days, describe appropriate scales on the x-axis and y-axis to graph the rate at which the slower growing plant increases in height. Assume that the height of the plant increases linearly. (5 points)

Answer 1

@ganeshie8

Answer 2

Plant A grows 2 inches per month ---------------- (1)

Answer 3

Plant B grows 1.8 meters in a year,

that means, it grows 1.8 x 39.37 inches in a year ?

Answer 4

1.8 x 39.37
----------------- inches per month ?
12

Answer 5

plug it in ur calculator, wat do u get ?

Answer 6

5.91 in. per year

Answer 7

5.91 in. per \(\color{red}{month}\)

Answer 8

after dividing by 12, it is 5.91
so its per month ok

Answer 9

sorry yea.

Answer 10

np :)

Plant B grows \(5.91\) in. per month

where as,

Plant A grows oly \(2\) in. per month

Answer 11

you can answer Part A ?

Answer 12

Plant B grows faster

Answer 13

Yes, and dont forget to justify it wid few sentences

Answer 14

wat about Part B ?

Answer 15

I don't know if they mean Plant A or B

Answer 16

Part B: If the original height of the plant was 2 inches, and you checked on its height every 15 days, describe appropriate scales on the x-axis and y-axis to graph the rate at which the \(\color{red}{slower ~growing ~plant}\) increases in height. Assume that the height of the plant increases linearly. (5 points)

Answer 17

So they mean Plant A

Answer 18

and since you're checking its growth every 15days,
you better put the scale on x-axis as : 1 grid = 15 days

Answer 19

Ok

Answer 20

and scale of y-axis as 1 grid = 1 in

Answer 21

cuz, in 15 days, Plant A grows 1 in.

Answer 22

fine ?

Answer 23

yes

Answer 24

good :)
