+    Let's define a function \( f(t) = t^2 - t \). We can rewrite the given condition as:
+    \[
+    f(x) + f(y) + f(z) = 4.
+    \]
+    We also need to find the maximum value of \( x^2 + y^2 + z^2 - x - y - z \), which can be expressed as:
+    \[
+    f(x) + f(y) + f(z) = 4.
+    \]
+    We know from the problem that \( f(t) \) is a convex function. By Jensen's Inequality, for convex functions:
+    \[
+    f(x) + f(y) + f(z) \geq 3f\left(\frac{x+y+z}{3}\right).
+    \]
+    Since \( f(x) + f(y) + f(z) = 4 \), we have:
+    \[
+    3f\left(\frac{x+y+z}{3}\right) \leq 4.
+    \]
+    This implies:
+    \[
+    f\left(\frac{x+y+z}{3}\right) \leq \frac{4}{3}.
+    \]
+    Since \( f(t) = t^2 - t \), we solve:
+    \[
+    \frac{4}{3} = \frac{1}{3}(x^2 + y^2 + z^2) - \frac{1}{3}(x + y + z).
+    \]
+    Multiplying both sides by 3, we get:
+    \[
+    4 = x^2 + y^2 + z^2 - (x + y + z).
+    \]
+    Thus, the maximum value of \( x^2 + y^2 + z^2 - x - y - z \) is \(\).

+    To determine the smallest number of positive divisors of \(M\), we need to analyze the structure of \(M\)'s divisors. Let \(M = 2^a \cdot 5^b \cdot 10^c\), where \(a, b, c \geq 3\).
+    
+    1. **Counting Divisors**: The total number of divisors of \(M\) is \((a+1)(b+1)(c+1)\).
+    
+    2. **Condition for Imbalanced**: For \(M\) to be imbalanced, at least 10% of its divisors must be greater than \(M/100\). This means \(M/100\) must be less than \(M/10\).
+    
+    3. **Simplifying the Condition**: The condition \(M/100 < M/10\) simplifies to \(100 < 10\), which is always true. Thus, any multiple of \(2000\) will inherently be imbalanced.
+    
+    4. **Minimizing Divisors**: To minimize the number of divisors, we should minimize \(a, b, c\). The smallest values for \(a, b, c\) that satisfy the conditions are \(a = 3, b = 3, c = 3\).
+    
+    5. **Calculating Divisors**: With \(a = 3, b = 3, c = 3\), the number of divisors is \((3+1)(3+1)(3+1) = 4 \cdot 4 \cdot 4 = 64\).
+    
+    6. **Conclusion**: The smallest possible number of positive divisors of \(M\) is \(\).

+    The insurance company will pay the actual damage, which is $2,350.
+    However, the insurance limit is $5,000, so the insurance company will not pay more than $5,000.
+    Since $2,350 is less than $5,000, the insurance company will pay the full $2,350.

+    To solve this problem, we need to use the stability constants and the given concentrations to determine the percentage of the blue dithiocyanato cobalt(II) complexes relative to all cobalt-containing species present.
+    First, we need to calculate the concentrations of each species using the stability constants and the given concentrations.
