D(t) = 0.8t^2. What is the average speed, in meters, per second of the rockm between 5 and 10 after was it dropped

The average speed is of 12 meters per second.

Step-by-step explanation:

The average speed can be given by the difference in position divided by the different in time.

Average speed, between 5 and 10 seconds.

d(t) = 0.8t²

d(5) = 0.8*(5)² = 20

d(10) = 0.8(10)² = 80

Times: 5 and 10 seconds. So

v = (80 - 20)/(10 - 5) = 12

The average speed is of 12 meters per second.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

the answer is 48m^2!
