Impedance and finite gain of operational amplifier

[ForexAnalyzer]

Hi , I just built a circuit shown.

For all operational amplifiers, I have set the Open Loop Gain to 0.9k

Input Resistance 18kOhm

Output Resistance 0.9kOhm

1. May I know how I can show that the output impedance and the gain values are based on my settings using instruments from Multisim 11?

2. How do I find the gain of the instrumentation amplifier using instruments in Multisim 11?

3. Lastly, how can I determine the slew rate of the instrumentation amplifier?

Thanks
