y(y-2)^2+3(y-2)=(y-2)[y(y-2)+3]=(y-2)(y^2-2y+3)

(y^3-4y^2+7y-6)(y-2)=(y-2)^2(y^2-2y+3)

If a geometric sequence has a2 = 495 and a6 = 311, approximate the value of the common ratio ???? to four decimal
shtirl [24]

Answer:

r = 0.8903

Step-by-step explanation:

given,

a₂ = 495

a₆ = 311

geometric  sequence formula

                       a_n = ar^{n-1}

                       a_2 = ar^{2-1}

                       a_2 = ar...................(1)

                       a_6 = ar^{6-1}

                       a_6 = ar^5................(2)

dividing equation (2) by (1)

                     \dfrac{a_6}{a_2} = \dfrac{ar^5}{ar}

                     \dfrac{311}{495} = r^4

                     r^4 = 0.628

                     r = 0.8903

hence, the common ratio of the geometric sequence is r = 0.8903

Which of these tables represents a function??
Bumek [7]

Answer:

The first table

Step-by-step explanation:

You have to make sure that x is unique throughout.

First Table: the inputs are 2, 4, 6, 7

each input value is different or unique

Second Table: input values are 3, 5, 3, 5

three and five repeat themselves, so there is not a function

Third Table: input values are -2, 0, 1, -2

negative 2 repeats itself so it is not unique
