Asprinter ran a race in 11 seconds. what is the domain of this graph?

The correct option is A. Real number from 0 to 11  

Step-by-step explanation:

Domain is defined as the all possible values of the variable x for which the function is defined.

Now, for the given graph the x-axis represents the time in seconds.

So, we need to find all the possible values of time for which the distance is covered or for which the function is defined.

Given that : The sprinter ran a race in 11 seconds.

And the initial time is 0 seconds

So, The value of t lies between 0 to 11

Thus, Domain : All real numbers 0 to 11

Therefore, The correct option is A. Real number from 0 to 11

a

step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
