1 answer:

6 0

The example of real life situations is: The cost of 30 green apples is €60
Rox wants to buy only 5 apples, how much will they cost her?

Cost of 30 green apples is €60.
Cost of 1 green apple = €60/30 = €2
(Using the concept of division of rational numbers)
Now, cost for 5 green apples =5 * €2 = €10

Which polynomial correctly combines the like terms and puts the given polynomial in standard form? -5x^3y^3+8x^4y^2-xy^5-2x^2y^4

victus00 [196]

Given:

The polynomial is:

$-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5$

To find:

The simplified form of the given polynomial in standard form.

Solution:

We have,

$-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5$

Combining the like terms, we get

$=-5x^3y^3+8x^4y^2+(-2x^2y^4+3x^2y^4)+8x^6+(-xy^5-6xy^5)$

$=-5x^3y^3+8x^4y^2+x^2y^4+8x^6-7xy^5$

Now, rewrite this polynomial in standard form.

$=8x^6+8x^4y^2-5x^3y^3+x^2y^4-7xy^5$

Therefore, the required polynomial in standard form is $8x^6+8x^4y^2-5x^3y^3+x^2y^4-7xy^5$ .

B. if lucinda has only $18 to spend and the price of kewpie dolls and the price of beanie babies are both $6, how many of each w

adoni [48]

Given the table below comparing the marginal benefit Lucinda gets from Kewpie dolls and Beanie Babies.

$\begin{tabular}
{|p {2cm}|p {2cm}|p {2cm}|p {2cm}|}
\multicolumn {4} {|c|} {Lucinda's Kewpie Doll and Beanie Baby Marginal Benefits}\\[1ex]
\multicolumn {2} {|c|} {Kewpie Dolls}&\multicolumn {2} {|c|} {Beanie Babies}\\[1ex]
1&\$15.00&1&\$12.00\\
2&\$12.00&2&\$10.00\\
3&\$9.00&3&\$8.00\\
4&\$6.00&4&\$6.00\\
5&\$3.00&5&\$4.00\\
6&\$0.00&6&\$2.00\\
\end{tabular}$

If lucinda has only $18 to spend and the price of kewpie dolls and the price of beanie babies are both $6,

Lucinda will buy the combination for which marginal benefit is the same.

Therefore, Lucinda will buy 2 kewpie dolls and 1 beanie baby, if she were rational.
