<span>r²sin²θ = 16rcosθ </span>

<span>rsin²θ = 16cosθ </span>

<span>r = 16cosθ / sin²θ </span>

<span>r = 16cotθcscθ</span>

A game is played with a played pentagonal spinner with sides marked 1 to 5. The scorer is on the side which comes to rest on the
slava [35]

Answer: probability of getting two 5s =0.04

probability of getting at least one 5 =0.36

probability of getting a total score greater than 5 =0.6

Step-by-step explanation:

Total outcomes on 1 spinner = 5

Then , total outcomes of spinning it 2 times=  5\times5 = 25

Number of outcomes for getting two 5's = 1

Then, the probability of getting two 5s =\dfrac{\text{Favorable outcomes of getting two 5's }}{\text{Total outcomes}}

=\dfrac{1}{25}=0.04

Number of outcomes for getting at least one 5 [ {(1,5),(2,5),(3,5),(4,5),(5,5), (5,1), (5,2), (5,3), (5,4)} ] =9

Then, the probability of getting at least one 5=\dfrac{\text{Favorable outcomes of getting at least one 5 }}{\text{Total outcomes}}

=\dfrac{9}{25}=0.36

Number of outcomes for getting a total score of 5, [ {(1,4),(4,1),(2,3),(3,2)} ] =4

Then, the probability of getting a total score of 5,=\dfrac{\text{Favorable outcomes of getting a total score of 5 }}{\text{Total outcomes}}

=\dfrac{4}{25}

Number of outcomes for getting a total score greater than 5 [ {(1,5),(5,1),(2,4),(4,2),(2,5), (5,2), (3,4),(4,3), (3,5), (5,3), (3,3), (4,5), (5,4), (4,4), (5,5)} ] =15

Then, the probability of getting a total score greater than 5,=\dfrac{\text{Favorable outcomes of getting a total score greater than 5 }}{\text{Total outcomes}}

=\dfrac{15}{25}=\dfrac{3}{5}=0.6

IRISSAK [1]
2. Distributive property (multiplying the -2 to the items in parentheses)
3. Subtraction property (subtracting 8 from 3)
4. Addition property (adding 5 to both sides)
5. -4x = 16 (subtracting 6x from both sides)
6. x = -4 (dividing both sides by -4)

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.
