Which function forms a geometric sequence when x = 1, 2, 3, ...?

The geometric sequence is found in the relationship between consecutive terms that is constant.
 In this problem, as I understand it, none of the functions forms a geometric sequence.
 The functions that form a geometric sequence have the form
 f (x) = h (a) ^ n where "a" is the constant relation between the successive terms.
 If you wrote the function "f (x) = - 2 (3/4) x", you wanted to write instead:
 f (x) = - 2 (3/4) ^ x
 So that would be the function that forms a geometric sequence, where the relation between the consecutive terms is 3/4.
 You can test it by dividing f (x) / f (x-1)
 Then you will see that the result of that division will be 3/4.

Answer:

<h2><u><em>17/12</em></u></h2>

Step-by-step explanation:

x - 3/4 = 2/3

x = 2/3 + 3/4

x = 17/12

----------------

check

17/12 - 3/4 = 2/3

Kayla squared a number x and added this result to -6.5. This gave her an answer of 42.5.
ladessa [460]

Answer:

7, -7

Step-by-step explanation:

x^2-6.5= 42.5 add 6.5 to both sides

x^2= 49

The square root of 49 is 7 and -7.

Passes through the points (−4, 2) and (12, 6)?
svlad2 [7]

<u>I'll assume you need to find the equation of the line that passes through those points.</u>

Answer:

\displaystyle y-2=\frac{1}{4}(x+4)

Step-by-step explanation:

<u>Equation of a Line:</u>

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

The given points are (-4,2) and (12,6), thus:

\displaystyle y-2=\frac{6-2}{12+4}(x+4)

Operating:

\displaystyle y-2=\frac{4}{16}(x+4)

Simplifying, the equation in point-slope form is:

\mathbf{\displaystyle y-2=\frac{1}{4}(x+4)}

The mean incubation time of fertilized eggs is 19 days. Suppose the incubation times are approximately normally distributed with
pochemuha

Answer:

a)17.92

b) 16.83 .... 21.17

Step-by-step explanation:

ρ→   z

0.14 = -1.080319341

-1.080 = (x - 19)/1 = 17.92

~~~~~~~~~~~~~~~~~~

3% / 2 = 1.5%

1.5% - 98.5%

ρ→   z

0.015 = -2.170090378 ....  -2.17 = (x-19) =16.83

0.985 = 2.170090378  ....   2.17 = (x-19) =21.17
