PLS HELP ASAP PLS PLSPLS What is the explicit formula for this sequence? 6, 2, -2, -6, ...

Mathematics
1 answer:
Marysya12 [62]3 years ago
5 0

Answer:

B

Step-by-step explanation:

this is just common sense. if you would have tried you could have easily answered this yourself.

the sequence starts with 6. that is a1.

so, the formula simply has to add "something" to 6.

therefore, A and D are out.

and then we see immediately that the sequence is built by subtracting 4 (or adding -4) for every step.

so, we need to add multiples of -4.

therefore, only B is correct (C adds multiples of +4).

crimeas [40]

Answer:

(2 , 5)

Step-by-step explanation:

point (x,y) that divides the segment   PI in the ratio 2 to 1

PD=4 - (-2) = 6     PE/ED=2/1     PE=2ED      PE+ED=6    3ED=6    ED=2   PE=4

coordinate of E (2,1)   .... 2 is x coordinate of E

DI=7-1=6    DF/FI=2/1     DF=4

coordinate of F (4,5)   .... .... 5 is y coordinate of E

CF // PD            PC/CI=DF/FI=2/1

C (2,5)

Given a * b=ba−ba+ab, find (2*3)×(3*2).
Vladimir79 [104]

Answer:

36

Step-by-step explanation:

a = (2×3) = 6

b = (3×2) = 6

Substitue into the equation:

                          a×b=ba−ba+ab

                                = 6×6 - 6×6 + 6×6

                                = 36 - 36 + 36

                                = 36

Therefore, (2*3)×(3*2) = 36

Hope this helps.☺

What is the domain of the function<br> f(x)=1x-3<br> -3 when the range is {-6. 0, 9}?
sineoko [7]

Answer:

D : { -3, 3, 12}

Step-by-step explanation:

I would suggest substituting the range for the function and solving for x like so.

i.e -6 = 1x-3, -6 + 3 = 1x -3 + 3, -3 = x, <u>x = </u><u>-</u><u>3</u><u>.</u>

0 = 1x - 3, 0 + 3 = 1x - 3 + 3, 3 = x, <u>x = 3</u><u>.</u>

9 = 1x - 3, 9 + 3 = 1x -3 + 3, 12 = x, <u>x = 12</u>
