how do you write the "quad" program for a ti83+ calc? is it...
PROGRAM:QUAD
:DISP "QUADRATIC FORMULA"
:DISP "ENTER VARIABLES"
:PROMPT A,B,C
:(-B+SQRTB^2-4*A*C))/(2*A)->X
:(-B-SQRTB^2-4*A*C))/(2*A)->Y

i have the program but i can't figure out how to space the letters? what key do you press to put spaces between letters?
any information is appreciated. thanks for your help.

"The specific heat capacity of copper is 0.092 calories per gram per degree Celsius. How much heat is required to raise the temperature of a 10-gm piece of copper from 0 degrees celsius to 100 degrees celsius? How does this compare with the heat needed to raise the temperature of the same mass of water through the same temperature difference?

I'm so lost....how do I go about solving a problem like this?....

"Pounding a nail into wood makes the nail warmer. Consider a 5-gram steel nail 6cm long and a hammer that exerts an average force of 500N on the nail when it is being driven into a piece of wood. The nail becomes hotter. Calculate the increase in the nail's temperature (Assume that the specific heat capacity of steel is 450J/kg*degC)"

I read in science books and national geographics that :
A - Oldest life form on earth is a tree in California at approximately 4500 years of age.
B - The oldest life form in the waters is a coral reef off the coast of Australia which is about 4500 years old.
C - Archeologists claim that the oldest evidence of money is from 4500 years ago.
D - There is no evidence that languages were evolved, but they all appear to have started in complex form about 4500 years ago in Middle East area.
E - The oldest desert on earth is the Sahara in Africa witch is calculated at 4500 years of age.
F - Niagara falls is claimed to be 4500 years old by some geologists.
G - The thick ice layers of the North Pole are claimed to be 4500 years old and not as initially calculated over millions of years.
H- There are thousands of frozen Mammoths found in Siberia who were only in about 4500 years dept of ice.
Is there a connection here?

What happened 4500 years ago on earth?
