Absolutely! Let's go through each problem one by one, double-checking the calculations.
### Problem 1: Distance between (2, 5) and (7, 3)
1. **Coordinates:**
- Point A: (2, 5)
- Point B: (7, 3)
2. **Calculate differences:**
- \( \Delta x = 7 - 2 = 5 \)
- \( \Delta y = 3 - 5 = -2 \)
3. **Apply Pythagorean theorem:**
\[
d = \sqrt{(5)^2 + (-2)^2} = \sqrt{25 + 4} = \sqrt{29}
\]
4. **Calculate \( \sqrt{29} \):**
- \( \sqrt{29} \approx 5.385 \)
5. **Round to the nearest hundredth:**
- \( d \approx 5.39 \)
**This is correct: The distance is 5.39.**
### Problem 2: Distance between (-1, 6) and (5, -2)
1. **Coordinates:**
- Point A: (-1, 6)
- Point B: (5, -2)
2. **Calculate differences:**
- \( \Delta x = 5 - (-1) = 5 + 1 = 6 \)
- \( \Delta y = -2 - 6 = -8 \)
3. **Apply Pythagorean theorem:**
\[
d = \sqrt{(6)^2 + (-8)^2} = \sqrt{36 + 64} = \sqrt{100}
\]
4. **Calculate \( \sqrt{100} \):**
- \( \sqrt{100} = 10 \)
**This is correct: The distance is 10.**
### Problem 3: Distance between (5, 5) and (2, -3)
1. **Coordinates:**
- Point A: (5, 5)
- Point B: (2, -3)
2. **Calculate differences:**
- \( \Delta x = 2 - 5 = -3 \)
- \( \Delta y = -3 - 5 = -8 \)
3. **Apply Pythagorean theorem:**
\[
d = \sqrt{(-3)^2 + (-8)^2} = \sqrt{9 + 64} = \sqrt{73}
\]
4. **Calculate \( \sqrt{73} \):**
- Using a calculator, \( \sqrt{73} \approx 8.544 \).
5. **Round to the nearest hundredth:**
- \( d \approx 8.54 \)
**This is correct: The distance is 8.54.**
### Summary of Results:
1. Distance between (2, 5) and (7, 3) = **5.39**
2. Distance between (-1, 6) and (5, -2) = **10**
3. Distance between (5, 5) and (2, -3) = **8.54**
