Question

can some one help me with this story question..... during a snow storm snow falls at a constant rate of 3 inches per hour from 2 pm to 5 pm then 2 inches per hr from 5 to 7 and 1/2 per hour from 7 to 9

Answer 1

what does the question ask?

Answer 2

it askes for me to draw a graph and what is the slope of each line segment

Answer 3

its wants how much the snow fell between 2 and 9

Answer 4

oooh i see
you will have a line with slope 2 starting at \((2,0)\) and ending at \((5,9)\)

Answer 5

then you will have a line with slope 2 from \((5,9)\) to \((7,13)\)

Answer 6

and then a line with slope \(\frac{1}{2}\) from from \((7,13)\) to \((9,14)\)

Answer 7

damn typo
first response should be a line with slope 3, not a line with slope 2

Answer 8

thank you

Answer 9

can u help me with a nother story problem

Answer 10

Don't forget to calculate how much snow fell between 2 and 9:

(3 in/hr for 3 hours) + (2 in/hr for 2 hours) + (1/2 in/hr for 2 hours)

Answer 11

\(9+4+1\) is how we ended up with \((9,14)\)

Answer 12

sure i will help if i can

Answer 13

the average women life span had ben tracked and the model for the data is y=0.2t + 73 where t corresponds to 1960 find and explain the meaning of the slope and y inyercept

Answer 14

the y intercept is what you get when t = 0.
in this case it means that in 1960 the average age was 73

Answer 15

that is because it says "t corresponds to 1960"

Answer 16

presumably it meant "t corresponds to the number of years AFTER 1960"

Answer 17

as for the slope, the \(.2\) means each year after 1960 the average life span increased by \(.2\) years or one fifth of a year

Answer 18

so 2 is the slope ?

Answer 19

i think it says \(\large .2\) right ?
point 2, not 2

Answer 20

0.2

Answer 21

or if you prefer \(0.2\)

Answer 22

yes, that is the slope

Answer 23

\(y=mx+b\) the slope is \(m\) and the y intercept is \(b\)

Answer 24

ok so the y means the 1960 right

Answer 25

the "y intercept" not "the y"

Answer 26

in other words, if the year is 1960 the t = 0 and the intercept is 73
so in 1960 the average life span was 73 years

Answer 27

thank you
