100%
The unity-feedback system in Figure P7.1 has the transfer function \( G(s) = \frac{K(s + \alpha)}{(s + \beta)^2} \).

**Description of the Figure:**
- The diagram shows a block diagram of a unity-feedback control system.
- The input signal is denoted as \( R(s) \).
- A summation junction is shown, where \( R(s) \) is added positively, and feedback is subtracted.
- The error signal \( E(s) \) is fed into the system block \( G(s) \).
- The output from the block, \( C(s) \), is fed back to the summation junction to complete the loop.

**Specifications:**
The system is designed to meet the following criteria:
- **Steady-State Error**: For a unit step input, the steady-state error is 0.1.
- **Damping Ratio**: 0.5
- **Natural Frequency**: \(\sqrt{10}\)

**Objective:**
Find the values of \( K \), \( \alpha \), and \( \beta \) that satisfy these specifications.
