Q. Find the distance between P(4,4) and Q(9,7).The distance between P and Q is □.(Simplify your answer. Type an exact answer using radicals as need
Distance Formula: To find the distance between two points P(x1,y1) and Q(x2,y2) in a 2-dimensional space, we use the distance formula which is derived from the Pythagorean theorem: Distance = (x2−x1)2+(y2−y1)2.
Substitute Coordinates: Substitute the given coordinates into the distance formula:P(4,4) and Q(9,7) gives us:Distance = (9−4)2+(7−4)2.
Calculate Differences: Calculate the differences:egin{math}(9 - 4) = 5 ext{ and }(7 - 4) = 3. ext{}
Square Differences: Square the differences: 52=25 and 32=9.
Add Squares: Add the squares of the differences: 25+9=34.
Find Distance: Take the square root of the sum to find the distance:Distance = 34.Since 34 is not a perfect square, we leave the answer in radical form.
