Answer 1

Try doubling the values. I think.

Answer 2

graph it on a graphing calculator first

Answer 3

Desmos Graphing Calculator is a good place to start. Try it.

Answer 4

I've already graphed it :)

Answer 5

¿Hablas chicos españoles ?

Answer 6

Excellent, what did you get?

Answer 7

Hola senor, como esta usted?

Answer 8

bien cómo estas?

Answer 9

umm.. A = 100 when t = 0?

Answer 10

Bien, gracias.

Answer 11

te gusta ayudar a las personas con las matemáticas ?

Answer 12

oops. I get it now!
k = 0.1 ^_^

Answer 13

Yo tambien.

Answer 14

That's good, butterflydreamer!

Answer 15

i dont get it, why is it 0.1

Answer 16

this question looks weird, the area is never twice its initial value though

Answer 17

Honestly, I don't know. What's your perspective?

Answer 18

Is that a good or bad thing?

Answer 19

initial value is 100
limiting value is 300

so there exists a value 200 somewhere in between right ?

Answer 20

oh 300 is limit? i thought it was decaying

Answer 21

Probably.

Answer 22

subtracting a decaying function from a big positive value gives an increasing function

Answer 23

Okay.

Answer 24

oops lol wasnt thinking

Answer 25

at t=inf we got A=300 ofcourse

Answer 26

would we have to solve these system of eqn then
\[dA/dt=10\\
200=300*(1-2/3 * e^{-kt})\]

Answer 27

yes k=0.1 is right

Answer 28

i concur
