<u>Answer:</u>

720

<u>Step-by-step explanation:</u>

We are given the following permutation problem to solve:

$_ 6 P _ 6$

We know that the number of possibilities to choose an ordered set of $r$ objects from a total of $n$ objects is given by:

$_ n P _ r = \frac { n ! } { ( n - r ) ! }$

Substituting the given values, n = 6, r = 6:

$_ 6 P _ 6 = \frac { 6 ! } { ( 6 - 6 ) ! }$ = 720

Find the 100th term in the arithmetic sequence

fiasKO [112]

$a_n=a_1+(n-1)d\\\\d=a_{n+1}-a_n$

$a_1=-19;\ a_2=-14;\ a_3=-9;\ a_4=-4;\ a_5=1;\ ...\\\\d=a_2-a_1=a_3-a_2=a_4-a_3=...\\\\d=-14-(-19)=-14+19=5\\\\a_n=-19+(n-1)(5)=-19+5n-5=5n-24\\\\a_{100}=5(100)-24=500-24=476\to\boxed{c.}$

Please help me !!!!!!

Given:

The set of pair and graphs.

To find:

The domain and range.

Solution:

We know that,

Domain is the set of x-values or input values.

Range is the set of y-values or output values.

(a)

The given set of ordered pairs is

{(-3,3),(5,5),(-3,2),(5,3)}

Here, the x-coordinates are -3, 5, -3, 5.

A set contains distinct values.

Therefore, the domain is {-3,5}.

(b)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,1),(-1,0.5),(-1,3),(0,0),(0,2),(1,0.5),(1,3)(2,1)}

Here, the y-values are 1, 0.5, 3, 0, 2, 0.5, 3, 1.

Therefore, the range is {0, 0.5, 1, 2, 3}.

(c)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,3),(-1,3),(0,1),(2,4)}

Here, the x-values are -2, -1,0, 2.

Therefore, the domain is {-2,-1,0,2}.

When vector is added to vector , the resultant is vector such that . This resultant vector has components Rx=Ax+BxRx=Ax+Bx and R

SVETLANKA909090 [29]

Answer:

a. When vector is added to vector , the resultant is vector such that its magnitude and direction is proportional to the resultant magnitude and direction of the component vectors.

b. ∅ = $tan^{-1}$ (Rx/Ry)

Step-by-step explanation:

Vectors are used to express physical quantities with magnitude and direction. Vectors can be added by the parallelogram method or the triangular method of addition. the magnitude and direction of the resultant vector is usually proportional to the magnitude and direction of the component vectors.

The direction of the angle is found as

tan∅ = Rx/Ry

∅ = $tan^{-1}$ (Rx/Ry)

Answer:

Question one: 3rd option

(Pt. 2 written):

b=ac^2

b=1/8 (4)^2

b= 2

Question two: It is option 2

(Pt. 2 written):

v= m-k

v= -2+7

v= 5

Question three: option 2

(Pt. 2 written):

q=ps/r

q=14(-4)/-7

q=-56/-7

q=8

Question four: It is choice number 3

(Pt. 2 written):

m=3n/4

m=3(8)/4

m=24/4

m=6

Question five: It is choice number 2

(Pt. 2 written):

x=wy+z

x=-8(-5)+6

x=40+6

x=46
