What sequence is modeled by the graph below?
Lady bird [3.3K]

ANSWER

a_n= \frac{1}{2}( {2}^{n - 1} )

EXPLANATION

The corresponding ordered pairs from the graph are:

(2,1) (3,2) (4,4) (5,8)

The y-values are:

1,2,4,8

The first term term is the term before 1,this has to be.

a_1= \frac{1}{2}

The common ratio is

r =  \frac{2}{1}  = 2

The nth term is given by

a_n=a_1 {(r}^{n - 1} )

Let's substitute the values to get,

a_n= \frac{1}{2} \times  {(2}^{n - 1} )

This simplifies to,

a_n= \frac{1}{2} {(2}^{n - 1} )

Which statements about the graph of the function Fx=-x2-4x+2 are true check all that apply
Irina-Kira [14]

Step-by-step explanation:

Just graph it and see if the descriptions fit the graph

(see attached)

A. We can see from the graph that the possible x-values are -∞ ≤ x ≤ +∞ . Hence limiting to domain to x≤ -2 this is obviously not true.

B. We can see from the graph that the vertex is y = 6 and that the entirety of the graph is under this point, hence range y<6 is true

C. We can see that the vertex is located at x=-2. Every part of the graph to the left of this point has a positive slope, hence the function is increasing for negative infinity to this point x=-2 is true

D) We can see that for the interval -4<x<∞, the graph actually increases between -4<x<-2, and then decreases after that. Hence this statement is not true.

E. it is obvious that the y intercept is y=2 which is positive. Hence this is true.

HELP ASAP PLEASE thanks youu
BlackZzzverrR [31]

Answer: Probably A

Step-by-step explanation: You need to use a ruler for this, because without one its impossible to get it exact

Using the ruler though, you'd measure each side of the wall and either use a ratio of 0.5in:4ft or multiply every 0.5in by 4ft.
