Answer:
So total number of pieces will be 2
Step-by-step explanation:
We have given the total length of the board
It is given that Luci cuts the board into pieces of long
We length of each piece =
We have to find the total number of pieces
For finding total number of pieces we have to divide the total length of board by length of each piece
So number of pieces = 2
Answer:
No, she used the diameter instead of the radius measure.
Step-by-step explanation:
we know that
The volume of the sphere is equal to
we have
----> the radius is half the diameter
substitute
Answer:
- The term with the greatest degree is
- The polynomial has degree 4 and is classified as a quadratic polynomial of 4 terms.
- It is not a polynomial.
Explanation:
<em>Polynomials</em> are expressions with terms composed of <em>monomials</em>.
A <em>monomial</em> is an expression formed by the product of a coefficient (constant numbers, like 3, 4/5, or even a root), and a literal part.
The literal part may consist of one or more letters and each letter may be raised to a non-negative integer number (positive or zero).
Hence, for instance, (2/9)x²y⁵z⁴³ is a monomial.
The given expressions are:
This expression is a polynomial formed by <em>4 terms </em>or monomials.
The monomials are:
The degrees of each monomial are:
Thus, the one with the <em>greatest degree</em> is . It defines the degree of the of the polynomial; hence <em>the polynomial has degree four and is classified as quartic polynomial of four terms.</em>
This is <em>not a polynomial</em>, because the letter in the last term, i.e. 1/x has a negative power:
As stated above, the powers have to be positive integers or zero (for the constant term).
Some special names used to classify the polynomials are:
- Degree 1 – linear
- Degree 2 – quadratic
- Degree 3 – cubic
- Degree 4 – quartic
- Degree 5 – quintic
You can find other classifications in your book or in the internet.
