Good answer Dragon for telling Anonymous the pattern.
Remember that -2^2 is really -1*(2^2) = -1 * 4 = -4
But (-2)^2 = (-2) *(-2) = 4
So, in the first case, the exponent only applies to the "2"....not the"-1"
Whereas, in the second example, the exponent apllies to the "-" and the "2"
That's how I do it.
6 + .50h = 2 + 1h where h is the number of repair hours
Subtract 2 from both sides and .50h from both sides
4 = .50h
Divide both sides by .50
h = 8
And the charges will be equal after 8 hours.....!!!!
I guess I'm not very hip....what's an Acrostic Poem ??????
On a simple calculator, type in 8255. Because 3*11=33, press these keys in the following order:
*==*==========
I think the "31mc006-1.jpg." isn't necessarily a common unit of angle measure in trig........!!!!!
Re-post ????
Thank you CPhill. I was wondering if you could an Acrostic Poem, if you like
MY PET ROCK
My pet rock was shy and aloof
Until he was much older
Now???
He's the life of the party
And you might say
He's gotten somewhat 'boulder"

To be specifc look every 1/infinity inch^(2).
2 ^ -4 = 1 / 2^4 = 1 / 16 = 0.0625
If you have a number to a negative exponent, rewrite that number in the denumerator with a positive exponent.
Place them in the same order as they are written in the triangle similarity:
CG / MK = GJ / KP = JC / PM
Thank you Pyramid. You are forgiven.
The digits mean:
34 7/4
In this number, the digits are 3, 4, 7, 4.
That's what I mean.
sorry anon,
Start by subtracting 2 from both sides.
First, factor out the x² term: x²(121x² - 36) = 0
Now, factor the remaining term as the difference of two squares:
x²(11x - 6)(11x + 6) = 0
Set each of the factors equal to 0: x² = 0 11x - 6 = 0 11x + 6 = 0
Finally, solve each of these reduced equations.
On the web2 calc is is
2nd atan 0.6092
make sure you have chosen the degrees button at the bottom of the calc.
arc tan is the same as inverse tan.
CPhill, please get the correct answer this time so you won't get negative 5 points again.
Pyramid, what I mean is to not give people negative points. It will give you bad fame later on...
Sorry, Pyramid, I don't understand your question.......can you be a little more specific about what it is you wish to do????
First, factor out an x: x(100x² - 121) = 0
Now, use he idea of the difference of two squares: x(10x-11)(10x+11) = 0
To solve this equation, set each factor to zero: x = 0 10x - 11 = 0 10x + 11 = 0
Now, solve each of the three little equations.
Pyramid, what are digits? And when someone gets the wrong answer, they just want to help you, so please dont give CPhill negative points. Can you please give them back?
-12.8 / 0.2 = 64
4.5 / 0.5 = 9
So 64 + 9 = 73 !!!!
I mean digits.
Any two odd numbers added together will produce an even !!! Example....3 + 5 = 8 !!!!! In fact, any even number of odd numbers added together will produce an even one...... (1 + 3 + 5 + 7 = 16, for example!!)
