what is the answer to this problem when you plug in infinity for t 1/5ln(5t+2)?

OpenStudy (anonymous):

0

OpenStudy (anonymous):

why isnt it infinity

OpenStudy (anonymous):

because any number divided by something approaching infinity goes to 0

OpenStudy (anonymous):

i wrote my question wrong

OpenStudy (anonymous):

is ln(5t+2) in the numerator?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

then it goes to infinity

OpenStudy (anonymous):

it's asking "e raised to what power is infinity"

OpenStudy (anonymous):

but its infinity plus a number

OpenStudy (anonymous):

which is still infinity

OpenStudy (anonymous):

infinity added to, multiplied by, or divided by any constant is still infinity

OpenStudy (anonymous):

what if its is being added to zero

OpenStudy (anonymous):

still infinity But, if it is multiplied by zero it's undefined

OpenStudy (anonymous):

infinity is an odd thing

OpenStudy (anonymous):

oh ok thank you
