Question

How do you work this problem on a scientific calculator? a=5,000e (.082)(12)

Answer 1

is e a variable?

Answer 2

The problem is a=Pe exponent rt

Answer 3

We are just not sure what buttons to push

Answer 4

Do you mean:

\[5000 \times e ^{0.82 \times 12}\]

Answer 5

13373.9

there should be an fancy "e" button on your calculator, it could be a second function (possibly second to sqrt)

Answer 6

Yes Mooby

Answer 7

What order do you input the problem?

Answer 8

5000 x e^(0.82 x 12) should do it.

Answer 9

what make and model of calculator do you have?

Answer 10

first you get a scientist, next ...

Answer 11

Yeah my answer's like the TI-83 version.

Answer 12

That is funny:) I will look at the calculator

Answer 13

TI 30xa

Answer 14

there should be an "e" button hidden on it someplace

Answer 15

Yeah either e or y^x.

Answer 16

When we push the ex button, it gives us an error

Answer 17

e^x is asking for the exponent to it, fill in m*n depending on what m and n are

Answer 18

i spose r*t in this case

Answer 19

I just looked up the calculator on Google Images. Try using this button:

\[y ^{x}\]

Answer 20

not very many functions on your calculator... I believe it is the

\[y^x\]

button

Answer 21

ok, so do we put 5000 x e?

Answer 22

google does it up for you as well.

5,000*e^((.082)*(12))

Answer 23

Oh, it does have an \[e ^{x}\]. Hrm.

Answer 24

I pushed 5000x e and it says error

Answer 25

Try doing it like this:

1. .82x12
2. e^x
3. x5000

Answer 26

so, put .82x12xex5000

Answer 27

did you try 2nd fxn LN?

Answer 28

yes

Answer 29

I am just not sure what to do in between the steps. Like to do I mulitply them?

Answer 30

.82x12 times e times 5000?

Answer 31

e is a function, you need not multiply

Answer 32

Yeah, I have TI-30X just realized there is no e key

Answer 33

so should i put .82x12 then hit e and then multiply by 5000?

Answer 34

13375.68 is the answer, but we just cannot get it on the cal

Answer 35

what brand name you got?

Answer 36

he has a TI 30xa

Answer 37

Texas instruments

Answer 39

this one?

Answer 40

YES!

Answer 41

seriously? there is a website devoted to pictures of calculators?

**logs off of FantasyGirls**

I know how I am going to spend my nights now.

Answer 42

Ha ha ha

Answer 43

2nd, ln, put in the r*t, hit " ) ", =

Answer 44

or exactly:

2nd
ln
.082
x
12
)
=

Answer 45

I come up with 0.984

Answer 46

might wanna include the principal too tho :)

Answer 47

where would we enter the 5000

Answer 48

you can just multiply your answer... i think...

Answer 49

afterwards just hit

x
5000

Answer 50

i have 49200 which is still not right

Answer 51

in general:

\begin{array}c
1.&5000\\
2.&2^{nd}\\
3.&ln\\
4.&.082\\
5.&x\\
6.&12\\
7.&)\\
8.&=\\
\end{array}

Answer 52

on step 3 I get an error

Answer 53

maybe hit "x" between steps 1 and 2

Answer 54

once you hit "ln", it should start itself off with a " ( ". if not, you might wanna include it

Answer 55

still comes out to 0.984

Answer 56

what about doing it on a TI-84 plus?

Answer 57

probably need to enter the exponent first
0.82 times 12 2nd ln times 5000

Answer 58

I got an error

Answer 59

change the batteries :)

Answer 60

Just did a few days ago:)

Answer 61

For the TI-30a: probably need to enter the exponent first
0.082 times 12 2nd LN times 5000 equal


For the TI-84 plus
5000 2nd LN 0.082 times 12 ) enter

Answer 62

the other is solar

Answer 63

YEA!!

Answer 64

Cruffo got it!!

Answer 65

.082*12 press"="
"2nd" "Ln" press"="
*5000 press "="

Answer 66

it works on the graph

Answer 67

THANK YOU GUYS!! GOD bless

Answer 68

On a Hewlett Packard stack oriented calculator, for example the HP12C:

12 press ENTER
. 082 press X (multiply)
press "e^x" the result of e^(12 times .082) is left in the display.
5000 press X (multiply) Final result is in the the display, 13375.68

Answer 69

Sorry.
"the the display" should have been typed, "the display"

Answer 70

RPN.... hummmmm
