1.) 60-(20% of 60)
60-(.2 * 60)
60-12
48
The pants are $48
2.)30% of x = 20
.3x = 20
.3x/.3= 20/.3
x = 66.6666666...
The pants were $66.67
3.) 25 + (20% of 25)
25+(.2*25)
25+5
30

Consider the polynomial 2x5 + 4x3 - 3x8
almond37 [142]

Answer:

Step-by-step explanation:

Considering the polynomial 2x⁵ + 4x³ - 3x⁸. The polynomial is not yet in standard form. For a polynomial to be in standard form, the power of the variables must decrease as we progress to the right of the expression.

A) The polynomial in standard form is therefore<u>   - 3x⁸ + 2x⁵ + 4x³</u>. <em>We can see that the power are reducing as we move through each terms i.e from 8 to 5 then to 3.</em>

<em />

B) The degree of a polynomial is the maximum degree among all the terms of the polynomial. The term that has the maximum degree is -3x⁸. Hence, the degree of the polynomial is 8

C) There are only 3 terms in the polynomial given. The terms are separated by mathematical signs. The terms if the polynomial are 2x⁵,  4x³ and - 3x⁸.

D) The leading term of the polynomial is the term that comes first after rewriting the polynomial in standard format. Given the standard from of the polynomial given as  -3x⁸ + 2x⁵ + 4x³, the leading term will be  - 3x⁸

E) Given the leading term to be  - 3x⁸, the leading coefficient of the polynomial will be the coefficient of the leading term. The coefficient of -3x⁸ is -3

The student body of 24 students
postnew [5]

There are 10,626 ways of arranging the required offices from a body of 24 students.

<h3>What is combination?</h3>

Combination deals with the way in which a arrangement can be made from a particular lot. In  this case, we want to select  a president, minister of Arts, minister of PE department, and minister of Science from a body of 24 students.

Hence;

24C4 = 24!/4! (24 - 4)! = 24!/4!20!

So;

24 * 23 * 22 * 21 * 20!/20! * 4 * 3 * 2*1

= 24 * 23 * 22 * 21 / 4 * 3 * 2*1

= 10,626 ways
