36, ___, ___, 32/3 is a geometric sequence, with some terms missing. First, please solve for "r", the common ratio between each
Nikitich [7]

Answer:

The geometric sequence is

36,24,16,\frac{32}3,.......

Step-by-step explanation:

The first term of the g.s is 36.

The 4th term of the given sequence is \frac{32}{3}.

The n^{th} term of the geometric sequence is

T_n=ar^{n-1}

Where a is the first term of the geometric sequence and r is the geometric sequence.

Then 4th term of the sequence is

T_4=ar^{4-1}

\Rightarrow \frac{32}3=36r^3

\Rightarrow  r^3=\frac{32}{3\times 36}

\Rightarrow r=\sqrt[3]{ \frac{8}{27}}

\Rightarrow r=\frac{2}{3}

Then, second term of the sequence   =36\times( \frac 23)^{2-1}

                                                              =36\times \frac 23

                                                             =24

The third term of the sequence is=36\times( \frac 23)^{3-1}

                                                       =36\times( \frac 23)^2

                                                        =16

The geometric sequence is

36,24,16,\frac{32}3,.......

Step-by-step explanation:

  -2 + (6)(-10) = -2 -60 = -62

__

2 less than a product is 2 subtracted from the product, or -2 added to the product. A product is formed by multiplying the given numbers.

The product of 6 and -10 is 6×(-10) = -60. 2 less than that is -62.

Solving for 9x^2 - 25 = 0

Standard form:

9x2 − 25 = 0

Solutions based on quadratic formula:

x1  

= −0 − √ 02 − 4×9×(−25)  

2×9

= 0 − 30 × √ 1  

18

≈ −1.667

x2  

= −0 + √ 02 − 4×9×(−25)  

2×9

= 0 + 30 × √ 1  

18

≈ 1.667

Extrema:

Min = (0, −25)
