<h3>A.</h3>
See below for a graph
<h3>B.</h3>
The inverse of a function appears on a graph as the reflection of the function across the line y=x. This is because the inverse relation is effectively the same relation with the variables x and y swapped. Here, the graphs of f(x) and g(x) are mirror images of each other across the line y=x, so we can see they are inverse functions.
The same technology allows us to graph y=f(g(x)) and y=g(f(x)). Both are graphs of y=x, as expected.
Answer:
245
Step-by-step explanation:
-6 cows produce 35 gallons
6 x 7 =42
so 7 x 35 = 245
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.

Let
x = cost of a ticket for a senior
y = cost of a ticket for an adult
z = cost of a ticket for a student.
The first student buys 2 senior, 1 adult, and 2 student tickets for $51.
Therefore
2x + y + 2z = 51 (1)
Th second student buys 1 adult and 5 student tickets for $5.
Therefore
y + 5z = 55 (2)
The third student buys 2 senior, 2 adult, and 7 student tickets for $75.
Therefore
2x + 2y + 7z = 75 (3)
Answer:
The system of equation for determining x, y, and z is
2x + y + 2z = 51
y + 5z = 55
2x + 2y + 7z = 75
Warnng: The system of equations does not have a solution.
