Answer:

the relation {(–2, –1), (–1, 1), (0, 1), (1, 0)}  is a function

the relation {(–2, –1), (–1, 0), (0, 1), (1, 0)} is a function

Step-by-step explanation:

the relation {(–2, –1), (–1, 1), (–1, 0), (0, 1), (1, 0)}

A relation is a function , when each input has only one output

First number in the relation is the input x

second number is the output y

The given relation is not a function because input -1 has to output 1  and 0

(–1, 1), (–1, 0)

To make this relation as a function , we need to remove (-1,1) or (-1,0)

the relation {(–2, –1), (–1, 1), (0, 1), (1, 0)}  is a function

the relation {(–2, –1), (–1, 0), (0, 1), (1, 0)} is a function

Find the sum of a finite geometric sequence from n = 1 to n = 7, using the expression −4(6)n − 1.
Verizon [17]

Answer:

<h2>-223,948</h2>

Step-by-step explanation:

The formula of a sum of terms of a gometric sequence:

S_n=a_1\cdot\dfrac{1-r^n}{1-r}

a₁ - first term

r - common ratio

We have

a_n=-4(6)^{n-1}

Calculate a₁. Put n = 1:

a_1=-4(6)^{1-1}=-4(6)^0=-4(1)=-4

Calculate the common ratio:

r=\dfrac{a_{n+1}}{a_n}\\\\a_{n+1}=-4(6)^{n+1-1}=-4(6)^n\\\\r=\dfrac{-4(6)^n}{-4(6)^{n-1}}=6^n:6^{n-1}\\\\\text{use}\ a^n:a^m=a^{n-m}\\\\r=6^{n-(n-1)}=6^{n-n+1}=6^1=6

\text{Substitute}\ a_1=-4,\ n=7,\ r=6:\\\\S_7=-4\cdot\dfrac{1-6^7}{1-6}=-4\cdot\dfrac{1-279936}{-5}=-4\cdot\dfrac{-279935}{-5}=(-4)(55987)\\\\S_7=-223948

Solve the system if possible by using Cramer's rule. If Cramer's rule does not apply, solve the system by using another method.
maks197457 [2]

Answer:

D = 0 , Dx = 4 , Dy = -6 , Dz = 2

Step-by-step explanation:

As per<u> cramer's rule</u>,

D = |   7    6    4  |  = 0

      |   3    3    3  |

      |   4    4    4  |

Dx =  |  10    6    4  | = 4

        |   1    3    3    |

        |   2    4    4   |

Dy = |   7    10    4  | = -6

       |   3    1     3   |

       |   4    2    4   |

Dz =  |  7    6    10 | = 2

        |   3    3    1   |

        |   4    4    2  |
