Q. Find the distance between the points (1,6)(1,6) and (4,2)(4,2).\newlineWrite your answer as a whole number or a fully simplified radical expression. Do not round.\newline______ units
  1. Distance Formula Explanation: To find the distance between two points in a coordinate plane, we use the distance formula, which is derived from the Pythagorean theorem. The distance formula is: (x2x1)2+(y2y1)2\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}. For the points (1,6)(1,6) and (4,2)(4,2), we have (x1,y1)=(1,6)(x_1, y_1) = (1, 6) and (x2,y2)=(4,2)(x_2, y_2) = (4, 2).
  2. Calculate X-coordinate Difference: First, we calculate the difference in the x-coordinates: (41)2(4-1)^2. This gives us (3)2=9(3)^2 = 9.
  3. Calculate Y-coordinate Difference: Next, we calculate the difference in the y-coordinates: (26)2(2-6)^2. This gives us (4)2=16(-4)^2 = 16.
  4. Add Squares of Differences: Now, we add the squares of the differences in the xx and yy coordinates to find the square of the distance: 9+169 + 16.\newlineThis gives us 2525.
  5. Find Square Root: Finally, we take the square root of the sum to find the distance: 25\sqrt{25}. This gives us 55.
