Answer: $12x - $275 = p
Step-by-step explanation:
$12x < how much it cost per seat/ticket
$275< How much they paid to rent the place
p< The profit
Ab + 2a + 5b + 10
= a(b + 2) + 5(b + 2)
= (b + 2) (a + 5)
2.1 m²
so um it's a regular hexagon since all of its side lengths are equal.

Answer:
Power generated = 4.315 kW
Step-by-step explanation:
Given,
- speed of wind when enters into the turbine, V = 12 m/s
- speed of wind when exits from the turbine, U = 9 m/s
- mass flow rate of the wind, m = 137 kg/s
According to the law of conservation of energy
Energy generated = change in kinetic energy
Since, the air is exiting at same elevation. So, we will consider only kinetic energy.
Energy generated in one second will be given by,


=4315.5 J
= 4.315 kJ
So, energy is generated in one second = 4.315 kJ
Power generated can be given by,

And the energy is generated is already in per second so power generated will be 4.315 kW.
