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 a gain of 10 pounds in math?
In mathematics, a gain of 10 pounds can be represented as an increase in a variable, typically denoted as ( x ). If the initial weight is ( x ), then the new weight after a gain of 10 pounds would be ( x + 10 ). This concept can be applied in various contexts, such as tracking weight changes or analyzing data in statistics. The gain reflects a positive change in the quantity being measured.
What difference did she make?
She made a significant impact by advocating for social justice and equality, inspiring others to join her cause. Her efforts led to important policy changes and raised awareness about critical issues affecting marginalized communities. Through her leadership, she fostered a sense of community and empowerment, encouraging individuals to take action and create positive change in their own lives. Ultimately, her legacy continues to inspire future generations.
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?
Accounting (including personal finances), population changes.
Have economic changes been positive or negative for Russia?
Negative.
How does the electric field direction change from positive to negative in a given system?
In a given system, the electric field direction changes from positive to negative when the source of the electric field changes its charge from positive to 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.
How do you write a word problem with integers?
To write a word problem with integers, start by identifying a real-life scenario that involves quantities that can be positive or negative, such as temperatures, bank balances, or elevation changes. Clearly define the context and the action involved, ensuring that the problem requires the use of integers to solve. For example, you might say, "A hiker starts at an elevation of 200 meters above sea level and descends 150 meters. What is the hiker's elevation now?" This scenario incorporates both positive and negative integers.
Who created the positive and negative electric change?
Nobody. Positive and negative electric changes exist from the earliest stages of the Big Bang.
What other effects did Europe have on Black Death positive or negative?
both positive and negative effects were there. It killed economy, but brought social changes.
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?
The changes in enthalpy, entropy, and free energy are negative for the freezing of water since energy is released as heat during the process. At lower temperatures, the freezing of water is more spontaneous as the negative change in enthalpy dominates over the positive change in entropy, making the overall change in free energy negative and leading to a spontaneous process.
Are sublimation and vaprization positive or negative?
Neither. They are simply phase changes.
What happens when you make changes to the environment?
Everyone is either affected in a positive or negative way
