im sorry!!!!

OpenStudy (anonymous):

why?

OpenStudy (anonymous):

i am not good at math.

OpenStudy (anonymous):

OpenStudy (anonymous):

It is 50 because 9.8/0.196=50

OpenStudy (anonymous):

$\int e^{kx} dx = \frac{1}{k} e^{kx} + c$

OpenStudy (anonymous):

wow. thanks. thank you so much!=)

OpenStudy (anonymous):

No worries :)

OpenStudy (anonymous):

wait. howcome we just divided it?

OpenStudy (anonymous):

because we are integrating so the rule is given by $\int ae^{kx} dx = \frac{a}{k}e^{kx}$ where a and k are constants

OpenStudy (anonymous):

if you derive the answer you will get the original equation. <--- you can use this fact to check your answer

OpenStudy (anonymous):

ah. so that's the rule. its the first time i knew that. whoops=) thanks.
