In a music stadium, 35th row has 120 seats

and explicit formula is  $a_{n}=3n+15$ is explicit formula for given sequence.

Step-by-step explanation:

In music stadium, there are 18 seats in first row and 21 seats in second row and it is continuously increasing by 3

Here, Arithmetic sequence is 18,21,24,27.....120

There Arithmetic sequence is given as a,a+d,a+d......a+(n-1)d

Where, a = First term = 18 and d = Increment = 3

Q (a) Write an explicit rule to model the sequence formed by the number of seats in each row.

Now, Create an explicit formula

$a_{n}=a+(n-1)d$

$a_{n}=18+(n-1)(3)$

$a_{n}=18+(3n-3)$

 $a_{n}=3n+15$ is explicit formula for given sequence.

Q (b) Use the rule to determine which row has 120 seats.

Given $a_{n}=120$

To determine which row has 120 seats.

$a_{n}=3n+15$

$120=3n+15$

$105=3n$

$n=35$

Therefore, 35th row has 120 seats

A math teacher instructed students to graph the following equations on a coordinate plane. y=2.5x+2 and y=2x+4. If graphed corre

algol [13]

Both the graphical lines will intersect at (4,12)

Step-by-step explanation:

Step 1; We must find the point in the graph where the lines of y=2.5x+2 and y=2x+4 intersect. To find out the intersecting point we must substitute values of x in both equations and see in which co-ordinate they are the same.

Step 2; We plot various values of x on the line governed by the equation y=2.5x+2

For a value of x=1 , y=2.5(1) + 2 = 4.5

For a value of x=2 , y=2.5(2) + 2 = 7

For a value of x= 3, y=2.5(3) + 2 = 9.5

For a value of x= 4, y=2.5(4) + 2 = 12

For a value of x= 5, y=2.5(5) + 2 = 14.5

Step 3; Now we also plot the values of x on the other line governed by y=2x+4

For a value of x= 1, y=2(1) + 4 = 6

For a value of x= 2, y=2(2) + 4 = 8

For a value of x= 3, y=2(3) + 4 = 10

For a value of x= 4, y=2(4) + 4 = 12

For a value of x= 5, y=2(5) + 4 = 14

Step 4; For both lines we must see if any of the values repeat at a particular point. In this case at the point (4,12) repeats for both so that becomes the point of intersection.
