What is 5 times negative 4 exponent 2 equal?
That depends. (odd thing to say about a math problem, I know...)If there are parentheses anywhere then it changes. But, without any it's 5*-4^2=-80However, with parentheses it'll be positive ... 80
How could you use Descartes' rule to predict the number of complex roots to a polynomial?
Descartes' rule of signs will not necessarily tell exact number of complex roots, but will give an idea. The Wikipedia article explains it pretty well, but here is a brief explanation:It is for single variable polynomials.Order the polynomial in descending powers [example: f(x) = ax³ + bx² + cx + d]Count number of sign changes between consecutive coefficients. This is the maximum possible real positive roots.Let function g(x) = f(-x), count number of sign changes, which is maximum number of real negative roots.Note these are maximums, not the actual numbers. Let p = positive maximum and q = negative maximum. Let m be the order (maximum power of the variable), which is also the total number of roots.So m - p - q = minimum number of complex roots. Note complex roots always occur in pairs, so number of complex roots will be {0, 2, 4, etc}.
What happens to a fraction when you divide it?
How a fraction changes when you divide it depends on what you divide it by.

What is the difference between the save option and the save as option in MSWord?
When you do a save, the changes are applied to the document you originally opened. When you do a 'save as', you have to choose a name and a location where a copy of the document will be saved; this copy will have changes you are currently making to the document. You can then exit the document without saving, and your original document is unchanged. The copy that you 'save as' is still intact, with changes. You can also do a 'save as' without making any changes, just to have another copy of the document existing with a new name and/or location.
What is the sign of the product of 11 negative integers and 2 positive integers?
The 2 positive integers don't affect the sign. Every time you multiply by a negative number, the sign changes, so you have negative, positive, negative, positive... Since the number of negative numbers is odd, the end result is negative.The 2 positive integers don't affect the sign.

Why is it when you multiply two negative integers that it is a positive answer?
Multiplying anything non-zero by a negative number changes the sign. A positive number multiplied by a negative number becomes negative. A negative number multiplied by a negative number becomes positive.
Where do you use positive and negative integers other than temperature?

Predict whether the changes in enthalpy entropy and free energy will be positive or negative for the freezing of water and explain your predictions How does temperature affect the spontaneity?
Enthalpy- positive Entropy- decreasing Free energy- negative

Negative.
Is this a positive or a negative change why history?
Industrial Revolution has both the negative and positive changes in the history of Americans.
Who created the positive and negative electric change?
Nobody. Positive and negative electric changes exist from the earliest stages of the Big Bang.
How voltage become zero in centre point?
If you have an alternating current, which changes direction, and we graph the direction in terms of positive and negative, then at some point, as the current changes from positive to negative, and from negative to positive, it must pass through zero. If you imagine a car, driving forwards, that then changes direction and drives in reverse, there must be a point when it is not moving. Changes of direction, or voltage, are not instantaneous.
