Text Solution

AI Generated Solution

To find the maximum number of points of intersection of 7 straight lines and 5 circles, considering that 3 straight lines are parallel and 2 circles are concentric, we can break down the problem into several steps: ### Step 1: Calculate the intersection points among the straight lines. - The maximum number of intersection points among \( n \) lines is given by the formula \( \binom{n}{2} \), which represents the number of ways to choose 2 lines from \( n \) lines. - For 7 lines, this would be: \[ \binom{7}{2} = \frac{7 \times 6}{2 \times 1} = 21 \] ...
