Sabrina threw a coin from a building 160 feet high at an initial speed of 30 feet per second. how many seconds will it take the coin to hit the ground?
a. 4.2
b.4.8
c.11.1
d.13.9

Is there a rate of acceleration? If not then by using the formula time = distance/speed you get 160/30. Which equals 5.333, so I would go with B. 

All you have to do is the distance divided by the speed, since they didn't mention acceleration, you do 160/30 = 5.33 repeating so just round it and go with B I guess. Hope it helps!

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
