Let's solve the problems one by one from the image you provided.

Problem 32:

You are asked to solve the inequality:

$x^2 - (a-2)x - 2a < 0$

and find the range of $a$ such that the inequality has exactly three integer solutions.

To solve it:

1. Rewrite the inequality: $x^2 - (a-2)x - 2a = 0$ This is a quadratic inequality.

2. The quadratic equation will have real solutions based on the discriminant: $\Delta = (a-2)^2 - 4 \cdot 1 \cdot (-2a)$ Simplifying: $\Delta = (a-2)^2 + 8a = a^2 + 4a + 4$

For the quadratic equation to have exactly three integer solutions, the value of $a$ needs to be found that satisfies this condition. The possible correct range for $a$ is based on further solving and factoring.

Based on the options, the correct answer will likely fall in:

$1 < a \leq 2 \quad \text{(Answer C)}.$

Problem 33:

The equation given is: $x + 2\sqrt{2}y - 2\sqrt{2} = 0$ You are asked to find the equation of the circle.

1. Rewrite the given line equation in standard form.

After simplifying and comparing, you find the standard form of the circle equation as:

$x^2 + y^2 = \frac{9}{16} \quad \text{(Answer E)}.$

Problem 34:

You are given 3 red balls and 2 blue balls, and asked to calculate the variance of the number of blue balls selected randomly.

This is a combinatorial probability problem, and the variance formula involves calculating expected values. The correct answer based on the formula for variance is:

$\frac{9}{25} \quad \text{(Answer D)}.$

Problem 35:

Given a parallelogram, you are asked to find a vector expression for vector $\vec{OM}$.

Using vector relations for the diagonals of the parallelogram and the section formula, the vector $\vec{OM}$ is calculated as:

$\vec{OM} = \frac{\vec{a}}{9} + \frac{\vec{c}}{3} \quad \text{(Answer D)}.$

Problem 36:

You are asked to divide $P(x) = (x-1)(x^2 + x + 1)$ by another polynomial.

The remainder after the division is calculated as:

$x^2 + 3x - 2 \quad \text{(Answer A)}.$
