Which function can be used to model the graphed geometric sequence?
andreev551 [17]

Answer: The correct option is 1, i.e., f(x+1)=\frac{5}{6}f(x).

Explanation:

The geometric sequence is in the form of,

a,ar,ar^2,ar^3,....

Where, a is the first term of the sequence and r is the common ratio of the sequence.

It means the n_{th} term of the sequence is defined as,

a_n=ar^{n-1}

So the the (n+1)_{th} term of the sequence is defined as,

a_{n+1}=ar^n

a_{n+1}=r(ar^{n-1})

a_{n+1}=ra_n

It means the geometric sequence is in the form of,

f(x+1)=rf(x)

Where, r be any constant.

From the options only f(x+1)=\frac{5}{6}f(x) is in the form of f(x+1)=rf(x) with common ratio \frac{5}{6}.

Therefore, the function can be used to model the graphed geometric sequence is f(x+1)=\frac{5}{6}f(x) .

Solve the proportion for the variable 6/y= 9/33
NeX [460]

Answer: y=22

Step-by-step explanation:

1. Multiply by <em>y</em> both sides of the equation, as following:

\frac{6y}{y}=\frac{9y}{33}\\\\6=\frac{9y}{33}

2. Now you must multiply by 33 both sides of the equation, as following:

6*33=\frac{9y}{33}*33\\198=9y

3. Now you must divide both sides of the equation by 9. Therefore, you obtain:

\frac{198}{9}=\frac{9y}{9}\\y=22
