In a section of a baseball stadium, there are 11 seats in the first row. There are 15 seats in the second row, 19 seats in the t
hird row, and
23 seats in the fourth row.
If the number of seats in each row follows the pattern described above, which recursive function defines the number of seats in the nth row?
A. f(1) = 11
f(n) = 4.f(n - 1), for n > 2
B. f(1) = 4
f(n) = f(n - 1) + 11, for n > 2
C. f(1) = 11
f(n) = f(n − 1) + 4, for n > 2
D.
f(1) = 4
f(n) = 11. f(n − 1), for n > 2
23 seats in the fourth row.

Answer:
t = 15.42 s
Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation.
We ned to find the time when the rocket will the ground. For this, y = 0
It is a quadratic equation whose solution is given by :
Here, a = -16, b = 242 and c = 73
Neglecting negative value.
So, it will hit the ground in 15.42 s.
Answer:
The values of n are less than 3 and more than (-5/2)
Step-by-step explanation:
The given inequality is :
-5 < 2n <6
We need to write the values of n.
Dividing both sides of the inequality by 2. So,
So, the values of n are less than 3 and more than (-5/2).
