They bought 8 orchestra seats and 6 mezzanine seats.
Step-by-step explanation:
Cost of one orchestra seat = $42
Cost of one mezzanine seat = $25
No. of people = 14
Amount spent = $486
Let,
x be the number of orchestra seats
y be the number of mezzanine seats
According to given statement;
x+y=14 Eqn 1
42x+25y=486 Eqn 2
Multiplying Eqn 1 by 25;

Subtracting Eqn 3 from Eqn 2 to eliminate y;

Dividing both sides by 17

Putting x=8 in Eqn 1

They bought 8 orchestra seats and 6 mezzanine seats.

Answer:
12.
Step-by-step explanation:
Average rate of change = (value of the function when x = 9 - value when x=3)
/
(9 - 3)
= f(9) - f(3) / (9-3)
= (9^2 - 3^2) / (9-3)
= 72 / 6
= 12.
Divide it by 25 witch is the height then find the square root
