@jim_thompson5910

jimthompson5910 (jim_thompson5910):

how far did you get here? what are your thoughts so far?

OpenStudy (itrymath):

i need a sec almost done with finding percent

OpenStudy (itrymath):

should be B

jimthompson5910 (jim_thompson5910):

hint: compute `1.008735^12`

OpenStudy (itrymath):

i did

jimthompson5910 (jim_thompson5910):

what did you get?

OpenStudy (itrymath):

1.12

OpenStudy (itrymath):

jimthompson5910 (jim_thompson5910):

I'm getting 1.11000536343484 try again

OpenStudy (itrymath):

oh then i added 1 more 1.01 oops

OpenStudy (itrymath):

yes 1.11

OpenStudy (itrymath):

jimthompson5910 (jim_thompson5910):

1.11000536343484-1 = 0.11000536343484 = 11% roughly

OpenStudy (itrymath):

2nd one is 49

jimthompson5910 (jim_thompson5910):

how did you get that?

OpenStudy (itrymath):

jimthompson5910 (jim_thompson5910):

you're given f(x). What is f(1) equal to?

OpenStudy (itrymath):

35 actually

jimthompson5910 (jim_thompson5910):

f(x) = 11*1.35^x f(1) = 11*1.35^1 f(1) = ???

OpenStudy (itrymath):

14.85

jimthompson5910 (jim_thompson5910):

so (1,1.45) is one point on this curve

jimthompson5910 (jim_thompson5910):

what is f(5) equal to?

OpenStudy (itrymath):

49. something

OpenStudy (itrymath):

49.32

jimthompson5910 (jim_thompson5910):

so (5, 49.3243678125) is another point on this line

jimthompson5910 (jim_thompson5910):

find the slope of the line through (1,1.45) and (5, 49.3243678125)

OpenStudy (itrymath):

back sorry

jimthompson5910 (jim_thompson5910):

are you able to find the slope?

OpenStudy (itrymath):

yes

OpenStudy (itrymath):

i got 4/47

OpenStudy (itrymath):

@jim_thompson5910 you there

jimthompson5910 (jim_thompson5910):

let me check

jimthompson5910 (jim_thompson5910):

you should get some decimal value. Did you use the slope formula?

OpenStudy (itrymath):

11.75? or 0.08

jimthompson5910 (jim_thompson5910):

m = (y2 - y1)/(x2 - x1) m = (49.3243678125 - 1.45)/(5 - 1) = ???

OpenStudy (itrymath):

4/47.87

jimthompson5910 (jim_thompson5910):

what is 49.3243678125 - 1.45 equal to?

OpenStudy (itrymath):

omg

OpenStudy (itrymath):

i used midpoint formula

OpenStudy (itrymath):

-_-

jimthompson5910 (jim_thompson5910):

Slope Formula \[\Large m = \frac{y_2 - y_1}{x_2 - x_1}\]

OpenStudy (itrymath):

I USED THAT

OpenStudy (itrymath):

-_-

jimthompson5910 (jim_thompson5910):

Slope Formula \[\Large m = \frac{y_2 - y_1}{x_2 - x_1}\] \[\Large m \approx \frac{49.3243678125 - 1.45}{5-1}\] \[\Large m \approx \frac{47.8743678125}{4}\] \[\Large m \approx 11.968591953125\] The slope is approximately 11.968591953125

OpenStudy (itrymath):

you gave me a set of points (1,1.45) (5,49.32)

OpenStudy (itrymath):

nvm you did it right and i did it wrong

OpenStudy (itrymath):

so whole number would be 12 right ?

jimthompson5910 (jim_thompson5910):

yes rounding 11.968591953125 to the nearest whole number leads to 12

OpenStudy (itrymath):

wow well wouldnt have done it without you thanks!

OpenStudy (itrymath):

i got a few more question mind sticking around, ill make new post
