how did u get that?

OpenStudy (anonymous):

im looking at the wrong question

OpenStudy (anonymous):

1/2*32=16

OpenStudy (anonymous):

hehe i think we have to use \[A = Ao e^{-kt}\]

OpenStudy (anonymous):

what? why cant they stick to whats on the homework

OpenStudy (anonymous):

so for 10 seconds =16

OpenStudy (anonymous):

it doesnt make since

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

damn this is going to be a long night

OpenStudy (anonymous):

OpenStudy (anonymous):

lol im not sure \[.5=e^{-k*10}\]or \[2=e^{-k*10}\]

OpenStudy (anonymous):

it could be \[A = 32 * e^{-0.069*t}\]

OpenStudy (anonymous):

this is messed up

OpenStudy (anonymous):

where did -.0.069

OpenStudy (anonymous):

solve for k

OpenStudy (anonymous):

\[16=32*e^{-k*10}\] \[k=0.069\]

OpenStudy (anonymous):

where did the 16 come from

OpenStudy (anonymous):

oh nevermind

OpenStudy (anonymous):

1/2 the 32

OpenStudy (anonymous):

so for 10 seconds its .069

OpenStudy (anonymous):

Hey where are you

OpenStudy (anonymous):

who, me?

OpenStudy (anonymous):

yes you you stole the cookie from the cookie jar

OpenStudy (anonymous):

huh, ur jar always been empty

OpenStudy (anonymous):

:( Why do you keep eating them

OpenStudy (anonymous):

haha; like u ever had any \[k = -0.069314718 = -0.069\] \[A= 32*e^{-0.069314718*t}\] u get 16, 8, 4, 2, 1 or \[A= 32*e^{-0.069*t}\] u get 16.1 , 8.1, 4, 2, 1
