Can someone please explain how to do this.
1 answer:
Set the to equal: x^2 - 4x+4 = 2x-4 solve for X subtract 2x from each side: x^2 -6x + 4 = -4 subtract 4 from each side: x^2 -6x = -8 add 8 to both sides: x^2 -6x +8 = 0 factor the polynomial: x = 4 and x = 2 using the line equation replace x with 2 and 4 and solve for y y = 2(2) - 4 = 0 y = 2(4)-4 = 4 so the 2 points the line crosses the curve is (2,0) and (4,4) using those 2 points you can calculate the length: distance = sqrt((x2-x1)^2 +(y2-y1)^2 distance = sqrt( (4-2)^2 + (4-0)^2) distance = sqrt (2^2 + 4^2) distance = sqrt (4+16) = sqrt 20 = 2 sqrt(5) EXACT LENGTH
