Answer based on context:

Hoping to recover from a two-game skid, the Cardinals flew to the Georgia Dome for a Week 4 match-up with the Atlanta Falcons.  From the get-go, the Cardinals trailed, as Falcons kicker Morten Andersen completed a 34-yard and a 40-yard field goal in the opening period.  The Cardinals would respond with a 29-yard field goal by kicker Neil Rackers.  In the second quarter, Arizona continued to trail, as Koenan belted a 51-yard field goal for Atlanta.  The Cardinals would strike back with SS Adrian Wilson returning an interception 99 yards for a touchdown, but that would be the only time that the Cardinals saw the lead, as Andersen got a 36-yard field goal to give the Falcons the lead at halftime.  In the second half, the Cardinals got shot down and shut-out, as Atlanta scored 20 unanswered points (Andersen's 26-yard field goal, CB DeAngelo Hall's 37-yard interception return in the third quarter, rookie RB Jerious Norwood's 78-yard TD run & Andersen's 28-yard field goal in the fourth quarter).  Not even QB Matt Leinart, who replaced QB Kurt Warner in the fourth quarter, could save Arizona from dropping three-straight games, as the Cardinals fell to 1-3. The game showed just how much the Cardinals must improve their offensive line, as they were whipped for the whole game by the Falcons defensive line.

how many yards did the cardinals response with?
29
