I see that you've uploaded an image containing a math problem sheet. I will analyze the image and extract the math problems for you.

Please hold on for a moment while I process the content.The image contains several mathematical questions, which cover various topics. I'll transcribe and summarize some of the questions for clarity:

### Questions Found in the Image:

1. **Question about growth and decrease percentages:**
   - If the population of a town grows by 10% in the first year, decreases by 5% in the second year, and grows by 5% in the third year, what is the total growth percentage after three years?

2. **Question about equation roots:**
   - If \( f(x) = 2x^2 - 5x + c \), where the roots of the equation are \( x = 2 \) and \( x = 3 \), find the value of \( c \).

3. **Logarithm and exponential expressions:**
   - Calculate the value of the expression \( \log_{10} 50 + \log_{10} 2 \).

4. **Geometric question involving angles and a polygon:**
   - A polygon has an interior angle of \( 120^\circ \). What is the number of sides of the polygon?

5. **Functions and limits:**
   - Find the limit of a function as \( x \) approaches infinity.

6. **Graph analysis problem:**
   - Determine the equation or properties of a graph based on a given figure.

Would you like me to solve specific questions from the list above, or is there any particular question you want to focus on?
