Question about Office Equipment & Supplies

(1+0.05)^24 = 3.2251

40000 * 3.2251 = 129004

say for 5% u have to do 40000*1.05=42000

for second time 42000*(1.05)=44100

and continue 18 times more

as you see actually you multiply 40000 by (1.05)(1.05)(1.05).........till 20 times

so calculate (1.05) to the power of 20 then multiply by 40000

Could it be that it has adding machine logic and not calculator logic?

Let's do an experiment. 3+ 3+ 5-. Is the answer 1?

If so, it is working like an adding machine. Every number you enter is considered positive or negative and it keeps a running total.

Let me know if you have any questions.

Good luck.

In response to your questions.

Have you thought about contacting Texas Instruments Directly?

Put in new (fresh batteries), and increase the contrast to the darkest, then reduce it. Do this a few times: It may bring the pixels back to life.

If that does not work, consider setting aside this calculator and buying a new one. It suffers from old age, and it is not worth it to try to repair it. Try to get a used one: If you risk nothing you get nothing. Besides that 200 $ figure is erroneous. You can get some good Casios (with a Computer Algebra System) for about 150$. Or a TI84 Plus Silver Edition C (in color) for the same price. OR a N'spire CAS, or an HP 50 G. Need I list others?

If result is positive it is an increase, Otherwise it is a decrease.

Percent change =100%*(new value-old value)/(old value)

If result is positive, it is an increase. If the value is negative it is a decrease.

100%*(50-45)45=100% *(5/45) =11.11 %

If result is positive, it is an increase. If the value is negative it is a decrease.

100%*(50-45)45=100% *(5/45) =11.11 %

So expected returns are just a little more advanced version of probability - without getting too in detail it uses weighted averages so you do not have to add the same number 17 times.

Let's first define our variables:

E(X) = Expected Return X1 = Variable 1 P1 = Probability 1 (in decimal format so 55% would be .55) X2 = Variable 2 P2 = Probability 2 (P2 is also equal to 1 - P1)

So the expected return formula is as follows:

E(X) = (X1)*(P1) + (X2)*(P2)

Plugging in our given numbers we get E(X) = Expected Return X1 = 300,000 P1 = 10% or .1 X2 = 40,000 P2 = 1 - P1 = 1 - .1 = .9

E(X) = (300,000)*(.1) + (40,000)*(.9) E(X) = 66,000

Now remember this does not include the opportunity cost of spending your four years in college studying biology instead of another degree.

Make sure your decimals are set to the correct number.

And also you can perform a factory reset on the unit to make sure all is back to normal.

Just be aware that it will delete any information which you have stored into your calc.

Resetting

After using the TI-89 and changing modes several times, you may set the calculator back

to all default modes by pressing 2nd 6 (MEM), F1(Reset) and 3 or by highlighting

3:Default and pressing ENTER. To reset all memory press 2nd, 6 (MEM) then F1(Reset)

and select 1: All.

Hello,

Make sure batteries are inserted correctly. Press [ON] then [CLEAR]. Increase the contrast

1. Press [2nd] key and release it.

2. Press [ArrpwUp] and release it.

3. Repeat steps 1 and 2 in sequence until contrast is to you liking.

Hope it helps.

your best bet in any kind of exponential equation is to set up the general form of the equation and then solve for the constants with the numbers they gave you. With P being population, t being time, you know it is going to look like P=Ae^(b*t) and you are given 2 P's for 2 t's.

So for the first set :

Eq 1 P(26)=40,000=Ae^(b*26)

and the second being a time t=0 P was half the current value:

Eq 2 P(0)=20,000=Ae^(b*0)

20,000=A*1 so A=20,000

now b from Eq 1

40,000=20,000e^(b*26)

Eq 1 P(26)=40,000=Ae^(b*26)

- Press and release the gold [2nd] button. Verify that the blinking up arrow appears in the display.
- Press
*and hold*the blue up or down arrow key to increase or decrease contrast, until the display is to your liking. Be alert: the display will change quickly.
