In a music stadium, <em>35th </em>row has <em>120</em> seats
and explicit formula is <em> </em>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
<em> is explicit formula for given sequence.</em>
Q (b) Use the rule to determine which row has 120 seats.
Given
To determine which row has 120 seats.
Therefore, 35th row has 120 seats
The Quadratic Function has the domain as the set of all real numbers.
For the range, start from minimum value to maximum value.
But because the parabola is downward as a < 0. Thus, there are no minimum value but the maximum value instead.
Therefore the range is y <= -4
