WILL MEDAL!! SOME ONE HELP PLEASE?!

OpenStudy (anonymous):

Don and Jacob want to know who reads more pages per hour. Don keeps track of the number of pages he reads in a graph, and Jacob keeps track of how many pages he reads in a table. How many pages per hour does each boy read, and who reads at a faster rate? Don: pages per hour Jacob: pages per hour The person who reads faster is: (Type D for Don or J for Jacob)

OpenStudy (anonymous):

How many pages per hour does each boy read, and who reads at a faster rate?

OpenStudy (anonymous):

Jacob’s Reading Log Time (h) 2 3.5 5 7 Pages read 42 73.5 105 147

OpenStudy (danjs):

Calculate the slope using 2 points on the table the graph is not showing

undeadknight26 (undeadknight26):

^ Couldnt have said it better.

OpenStudy (anonymous):

OpenStudy (danjs):

calculate the slope of the line using 2 points, calculate the slope of the table using 2 points, compare the two numbers

OpenStudy (anonymous):

how do i do that?

OpenStudy (danjs):

\[m = slope = \frac{ y - y1 }{ x-x1 }\] for 2 points (x,y) and (x1,y1)

OpenStudy (anonymous):

alright, then what?

OpenStudy (danjs):

That value, the slope, is the rate of reading in pages per hour

OpenStudy (anonymous):

oh ok,

OpenStudy (anonymous):

so who reads the fastest?

OpenStudy (danjs):

the one with the greater value for the slope, you have to calculate it

OpenStudy (danjs):

I will do the table:

OpenStudy (danjs):

2 points (2, 42) and (3.5, 73.5) \[m = \frac{ y - y1 }{ x-x1 } = \frac{ 73.5-42 }{ 3.5-2 } = \frac{ 31.5 }{ 1.5 } = \frac{ 21~pages }{ 1~hour }\]

OpenStudy (danjs):

Do the same using 2 points from the graph

OpenStudy (anonymous):

kk

OpenStudy (anonymous):

D (Don) = 18 pages/hour

OpenStudy (danjs):

right

OpenStudy (anonymous):

so Jacob reads faster than don?

OpenStudy (danjs):

yes

OpenStudy (anonymous):

ty you much

OpenStudy (anonymous):

WHAT DAFUQ?! WHAT'S JACOB'S @DanJS

Summary for peeps looking for answers: Don - 18 Jacob - 21 Fastest - Jacob
