An arithmetic sequence has first term a = 5 and common difference d = 4. how many terms of this sequence must be added to get 41

Stels [109]

Given that in arithmetic sequence a=5 and common difference, d=4. Thus the number of terms of this sequence that must be added to attain 4185 will be found as follows:
the explicit formula for arithmetic sequence is given by:
sn=n/2(2a+(n-1)d)
where n is the number of terms:
thus plugging in the values we get:
4185=n/2(2*5+(n-1)4)
solving for n we get:
8370=(10+4n-4)
8370=(6+4n)
4n=8364
n=8364/4
n=2091
thus the number of terms will be:
2091

Which system of equations could be graphed to solve the equation below?

Taya2010 [7]

Answer:

$\left\{\begin{array}{l}y_1=\log (2x+1)\\ \\y_2=3x-2\end{array}\right.$

Step-by-step explanation:

Given the equation

$\log (2x+1)=3x-2$

This equation consists of two parts. In the left part, there is a logarithmic function $y=log (2x+1)$

In the right part, there is a linear function $y=3x-2$

To solve the equation graphically, you have to plot the graphs of these two functions and find the point of intersection of these graphs.

Hence, appropriate system is

$\left\{\begin{array}{l}y_1=\log (2x+1)\\ \\y_2=3x-2\end{array}\right.$

Answer:

the graph is attached below

Step-by-step explanation:

$y=x^2 - 2$

LEts make a table to get the coordinates

we need to select integers between -3 and 3

x y=x^2 - 2

-2 y=(-2)^2-2=2 (-2,2)

0 y= (0)^2 - 2= -2 (0,-2)

2 y=(2)^2-2 = 2 (2,2)

Now we use the table for graphing the given equation
