In a chemical reaction the concentration of a certain solution decreases bu 20% every 100 seconds

This question doesn’t make any sense

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000

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
