A cannonball is launched upwards. Its height is described by the equation h= -5t2 + 40t + 45, where
is measured in yards and t is measured in seconds.
How high is the cannonball at 0 second?

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
