Find each unit rate. $30 for 8 students
Usimov [2.4K]

Answer:

One student costs $3.75

Step-by-step explanation:

Unit rate is how much it is for 1 item. In this case, we want to know the cost for 1 student.

$30/8 students ... if it is $30/8 students, you can divide by 8 to find out how much it is for one student.

$30/8 = $3.75

Determine if the set of polynomials {x^2 –2x+1, 2x² + 3x -4,-x2+x+5) is a linearly independent set in P2. Is it a basis for P? W
WITCHER [35]

Answer with Step-by-step explanation:

We are given that a set of polynomials {x^2-2x+1,2x^2+3x-4,-x^2+x+5}

We have to find that given set is a linearly independent set inP_2

and given set is a basis for P_2 or not.

Matrix of given set of polynomials

A=\left[\begin{array}{ccc}1&-2&1\\2&3&-4\\-1&1&5\end{array}\right]

Linearly Independent set :If any row or any column is not a linear combination of other rows or columns then the set is linearly independent set.

Any row or column  is not a  linear combination of other rows or columns.Therefore, given set is  a linearly independent set .

We know that

P_2=x^2

Element of P_2 is of the form

ax^2+bx+c

Every element of p_2 is a linear combination of given set of polynomials.

Hence, given set is linearly independent in p_2 .

If any set is basis for any vector space then it satisfied the following two conditions

1.Given set is linearly independent.

2.Every element of given vector space spanned by the given set.

Given set of polynomials are linearly independent and spanned every element of P_2.

Therefore, given set is  as basis for p_2 because the set is linearly independent and spanned P_2.
