Continue the pattern: 3-6,12,4,20​
Brrunno [24]

Answer:

The most likely solution sought is 13:

Beginning with 3: subtract 9, add 18, subtract 8, add 16, subtract 7, add 14, etc. Each time, reduce the number subtracted by one, and double that number to add.

So, beginning with 3: 3-9 = -6, -6+2(9) = 12, 12-8 = 4, 4+2(8) = 20, 20-7 = 13, etc.

Class: Constructing graphs Student Activity Sheet 2; Exploring "Representing data" Date Page 2 of 7 3. What do you notice about
krok68 [10]

Answer:

Explained below.

Step-by-step explanation:

The vertical axis of Graph A represents the year for which the population of Benton is recorded.

Also the axis represents every other year, i.e. 2002, 2004, 2006 and so on.

This implies that the data is recorded for every other year.

Consider the data provided:

Benton population in 1000s             Year

               10                                     2002

               11                                     2004

               12                                     2006

               13                                     2008

               14                                     2010  ​

For every 2 years the population of Benton is increasing by 1000.

That is for every year the population of Benton is increasing by 500.

If we make the vertical axis using the years:

2001, 2002, 2003, 2004, 2005, 2006 and so on, the graph will remain same with more points to plot.

So, on altering the vertical axis the graph does not changes much.

Use the quadratic formula to solve x2 – 5x + 3 = 0.
Anit [1.1K]

Answer:

x is 4.30 and 0.697

Step-by-step explanation:

Quadratic formular:

x =  \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a}  \\

a » 1

b » -5

c » 3

x =  \frac{ - ( - 5)± \sqrt{ {( - 5)}^{2}  - (4 \times 1 \times 3)}  }{(2 \times 1)}  \\  \\ x =  \frac{5± \sqrt{13} }{2}

Therefore, values of x :

x =  \frac{5 +  \sqrt{13} }{2}  \:  \: and \:  \:  \frac{5 -  \sqrt{13} }{2}  \\  \\ x = 4.30 \:  \: and \:  \: 0.697
