James drops a water balloon from a height of 45 m. how long will it take the water balloon to hit the ground? use the formula where v0 is the initial velocity and h0 is the initial height. round to the nearest tenth of a second.

When the water balloon hits the ground, its height is zero. Thus, we want to solve for . Therefore, .
Since James drops the balloon, we know that its initial velocity is zero. Thus, .
Since James drops the balloon from a height of 45 m, its initial height is 45 m. Thus, .
Plugging these numbers into the equation, we get .
Reducing this equation, we get , then . Taking the square root of both sides, we get and .
Since t can't be negative, .

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
