A person tosses an object off the top of a building. The object's height after x seconds can be modeled by the equation y = −12.31x^2 + 1.32x + 31.02. Find the amount of time it takes for the object to hit the ground. Round to the nearest hundredth.

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.

Write the fraction 9/50 as a decimal if needed round to the nearest hundredth

An object is translated by (x + 4, y - 2). if one point in the image has the coordinates (5, -3), what would be the coordinates of its pre-image? (9, -5) (1, -5) (9, -1) (1, -1)
