1_A polynomial is a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients. A polynomial in one variable (i.e., a univariate polynomial) with constant coefficients is given by

3_A form of arch defined by a moving point which remains equidistant from a fixed point inside the arch and a moving point along a line. This shape when inverted into an arch structure results in a form which allows equal vertical loading along its length. A parabola is the graph of a quadratic equation

5_ Here are some examples

Here is a harder one to understand:
-42
Now, the negative sign out front must wait till the raise to a power operation is finished. So, four raised to the second power is sixteen, since four times four is sixteen. After that evaluation the negative sign accepts the value of sixteen as an operand and produces a value of negative sixteen. Therefore, we can write:
-16 = -42
In other words, -42 does not mean negative four times negative four. That would be positive sixteen. Some calculators give this result; so, be careful and make sure that you understand how the calculator that you are using works.

The exponent may be negative. Consider this expression:

4-3

The negative sign on the exponent means that this power has the value of one divided by four raised to the third power. That is:

1 / 43 = 4-3

6_ Here's an example:
Let r be the original radius. Original area = πr²
If the radius is doubled, then the area of the new circle is = π(2r)² = 4πr²
So the ratio for area of old circle : new circle = πr² : 4πr² = 1: 4
