Question

@bibby can u Plzzzz help mee?!?

Answer 1

HI!!

Answer 2

help with what?

Answer 3

i bet it is trig

Answer 4

Graph the six terms of a finite series where a1 = -3 and r = 1.5.

graphed sequence showing point 1, 2.25, point 2, 3.75, point 3, 8.25, point 4, 21.75, point 5, 62.25, and point 6, 183.75
graphed sequence showing point 1, 1.5, point 2, 3.75, point 3, 10.5, point 4, 30.75, point 5, 91.5, and point 6, 273.75
graphed sequence showing point 1, negative 9, point 2, negative 12, point 3, negative 16.5, point 4, negative 23.25, point 5, negative 33.38, and point 6, negative 48.56
graphed sequence showing point 1, negative 3, point 2, negative 7.5, point 3, negative 14.25, point 4, negative 24.38, point 5, negative 39.56, and point 6, negative 62.34

Answer 5

\[a_1=-3,a_2=-3\times 1.5=-4.5, a_3=-3(1.5)^2=-6.7\]

Answer 6

does on start out \((1,-3),(2,-4.5),(3,-6.75)\)

Answer 7

i don't see it
i has to start out \((1,-3)\)

Answer 8

it's D!! thxx! @satellite73

Answer 9

yeah but the second one should be \((2,-4.5)\) and it is not ...

Answer 10

unless it really should be a1 = -3, r=2.5

Answer 11

no r is 1.5

Answer 12

I dont see the answer either

Answer 13

@satellite73

Answer 14

hmm then there is a mistake
has to be -3,-4.5,-6.75, ...
not sure what advice to give, i am certain that is the answer

Answer 15

ughhh

Answer 16

really nothing you can do
i assume these are pictures right?

Answer 17

yes

Answer 18

i'll attach them

Answer 19

it really has to start \((1,-3)\)since it tell you \(a_1=-3\) unless that is typo

Answer 20

yeah and D starts with (1, -3)

Answer 21

@satellite73

Answer 22

ok fine the correct answer is not there, go with D and move on
not worth fretting about
you are sure a1 = -3, r = 1.5 right? don't sweat it, don't get frustrated, moveon.org or write and say the correct answer is not shown

Answer 23

i cant write its multiple choice and yes i'm sure

Answer 24

Calculate the average rate of change for the graphed sequence from n = 2 to n = 4.

graphed sequence showing point 1, negative 3, point 2, negative 3.5, point 3, negative 6.75, point 4, negative 10.125, point 5, negative 15.1875, and point 6, negative 22.78125

-6.625
-03.3125
-3.0
-2.0

Answer 25

then you have to accept defeat
they made a mistake, there is nothing you can do
don't worry about it
if there is really no way to write them, (which is stupid) then you can do nothing

Answer 26

\[\frac{-10.125+5.3}{4-2}\]

Answer 27

oops

Answer 28

i got -3.21

Answer 29

yeah B

Answer 30

Graph the first six terms of a sequence where a1 = -10 and d = 3.

graphed sequence showing point 1, negative 10, point 2, negative 7, point 3, negative 4, point 4, negative 1, point 5, 2, and point 6, 5
graphed sequence showing point 1, negative 7, point 2, negative 4, point 3, negative 1, point 4, 2, point 5, 5, and point 6, 8
graphed sequence showing point 1, negative 7, point 2, negative 17, point 3, negative 27, point 4, negative 37, point 5, negative 47, and point 6, negative 57
graphed sequence showing point 1, 3, point 2, negative 7, point 3, negative 17, point 4, negative 27, point 5, negative 37, and point 6, negative 47

Answer 31

ok we really gotta stop that "point" stuff
just type it in or copy or something
this si like impossible to read

Answer 32

okay sorry

Answer 33

lets just compute it

Answer 34

\[-10,-10+3,-10+2*3,-10+3*3...\] or
\[-10,-7,-4,-1,2,...\]

Answer 35

A (1,-10) (2,-7) (3,-4) (4,-1) (5,2) (6,5)

Answer 36

that looks good
go no further

Answer 37

so thats the answer?

Answer 38

yes

Answer 39

thanks!!

Answer 40

Calculate the average rate of change for the graphed sequence from n = 2 to n = 6.

graphed sequence showing point 1, 17, point 2, 14, point 3, 11, point 4, 8, point 5, 5, and point 6, 2

-9
-4
-3
-2

Answer 41

@satellite73

Answer 42

\[\frac{2-14}{6-2}\]

Answer 43

thanks!! last one!

Answer 44

i.e \(-3\)

Answer 45

Graph the first six terms of a sequence where a1 = 2 and r = 4.

graphed sequence showing point 1, 8, point 2, 16, point 3, 32, point 4, 64, point 5, 128, and point 6, 256
graphed sequence showing point 1, 8, point 2, 8, point 3, 16, point 4, 32, point 5, 64, and point 6, 128
graphed sequence showing point 1, 2, point 2, 8, point 3, 32, point 4, 128, point 5, 512, and point 6, 2048
graphed sequence showing point 1, 8, point 2, 32, point 3, 128, point 4, 512, and point 5, 2048, point 6, 8192

Answer 46

wait -3 or -4 i got -4

Answer 47

@satellite73

Answer 48

\[2-14=-12\\
6-2=4\] and \(-12\div 4=-3\) right?

Answer 49

oops lol

Answer 50

ok for the last one, \(a_1=,,r=4\) right ?

Answer 51

oops \(a_1=2,r=4\)

Answer 52

a1 is 2

Answer 53

ok so
\[(1,2),(2,8),(3,32),(4,128)\] etc

Answer 54

(5,512) (6,2048) yes

Answer 55

yeah you are multiplying by 4 each time

Answer 56

yeah thanks

Answer 57

that it?

Answer 58

yep!! got a 100%

Answer 59

lol imagine

Answer 60

xD
