Answer:

[2, 5)

Step-by-step explanation:

The vertical extent of the function is its <em>range</em>. Here, that extent is from y=2 to y=5, except that y=5 is <em>not included</em> (indicated by the open circle on the graph). So, the range is ...

2 ≤ y < 5

In interval notation, we use a square bracket when the end point is included, and a curved parenthesis when it is not.

range: [2, 5)

The formula for the nth term of an arithmetic sequence can be found using the formula a Subscript n Baseline = a Subscript 1 Bas

Gnoma [55]

The equation of nth term will be written as for n as will be ( $\rm a_n$ - a₁ + d) / d. Then the correct option is D.

The missing options are attached to the picture given below.

<h3>What is a sequence?</h3>

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The formula for the nth term of an arithmetic sequence can be found using the formula given below.

$\rm a_n = a_1 + (n-1)d$

Then arrange the equation for n, we have

$\begin{aligned} \rm a_n - a_1 & \rm = nd - d\\\\\rm a_n - a_1 + d & \rm =nd\\\\\rm n & \rm = \dfrac{a_n - a_1 + d}{d} \end{aligned}$

Then the correct option is D.

Answer:

x = 18

Step-by-step explanation:

The scale factor between the two numerators are 1/2.

Scale factor

= numeratorANS / numeratorKNOWN

= 7/14

= 1/2

Multiply the denominator by the scale factor to find x.

x = 36 * 1/2

x = 18
