Answer: For the equation simply substitute 30 in for v and 4 in for s in the equation given, so H=-16t^2+30t+4
Part 2.
If the juggler misses the ball, you wish to know the time that it takes for the ball to travel the four feet from his hand to the ground, so respectively,
4=-16t^2+30t+4 or 0=-16t^2+30t or 0 = -16t+30,
solving for t, t =30/16 seconds or 1.875 seconds
Step-by-step explanation:
The total distance must be greater than 80. She has already ridden 18 miles. And she will continue to ride m miles per day for at least 6 more days, so:
6m+18>80
More "work"...
distance>80
distance=18+6m
6m+18>80
Answer:
306
Step-by-step explanation:
6*9=54
54*4=216
216+90=306
