b and d

Step-by-step explanation:

The maximum height of the ball was 30 feet

The ball was in the air for 6 seconds

Step-by-step explanation:

The maximum height was 30 feet because that is the highest y-value before the y-values start decreasing. You could also call it the peak.

You would know the ball was in the air for 6 seconds because the time elapsed between it's liftoff at 0 feet and it's landing at the other 0 feet was 6 seconds.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
