Hey there!

A binomial is a polynomial that contains two terms. Terms are separated from one another by mathematical symbols, such as +, –, and ×. A term can be a variable, a variable with a coefficient, a constant, or really any combination of coefficient, variable, and exponent that you can think of. For example...

(3x² – xy)

(x + 3)

(5x – 6y)

...are all binomials.

Hope this helped you out! :-)

risa is sewing a ribbon around the sides of a square blanket. Each side of the blanket is 72 inches long. How Many inches of rib

lidiya [134]

Answer: Risa need 72 inch of ribbon.
To answer this question you just need to find how long the blanket perimeter. The blanket is a square with 72 inch length. To count the perimeter of a square you need to multiply the length with 4. Then the square would be : 4x 72 inch= 288 inch.

What does it mean to determine the two positive integers that each value is between??? I'm confused

KIM [24]

Answer:

11. {7, 8}

12. {8, 9}

13. {8, 9}

14. {4, 5}

Step-by-step explanation:

You want consecutive integers that bracket each of the given irrational roots.

<h3>Square roots</h3>

A square root of an integer will be rational only if the integer is a perfect square. The first few perfect squares are ...

1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81

You know these because you know your multiplication tables.

The square root of a number between these perfect squares will lie between the roots of the squares.

50 lies between the squares 49 = 7² and 64 = 8². That means √50 lies between 7 and 8.

Your calculator tells you that √50 ≈ 7.0710678, which is a number that lies between the integers 7 and 8.

72 lies between the squares 64 = 8² and 81 = 9². That means √72 lies between 8 and 9.

65 lies between the squares 64 = 8² and 91 = 9². That means √65 lies between 8 and 9.

23 lies between the squares 16 = 4² and 25 = 5². That means √23 lies between 4 and 5.

<em>Additional comment</em>

The purpose of questions like this appears to be to have you make use of your knowledge of integer perfect squares to guess an approximation of a square root.

A calculator can answer these questions immediately. Of course the two consecutive integers are the integer part of the root, and the next higher integer.

The question is not well-posed. The answer to "integers each value is between" could be 1 < √50 < 50. For integers greater than 1, the square root is always smaller than the integer being rooted. We've seen questions like this enough times that we can guess the intention is for you to identify <em>consecutive</em> integers.

<em>Extra credit</em>

Knowing the integer part of the root and the difference between the number and its next lower perfect square, you can approximate the root as follows:

For integer n = a² +b, the root √n lies between a +b/(2a+1) and a +b/(2a).

For example, 65 = 8²+1, so √65 lies between 8 1/17 and 8 1/16.
