Answer:
Set up your height equation, then factor or use quadratic formula to find when h(t)=0
Step-by-step explanation:
Your equation will be -16t^2+vt +h where v is the initial velocity and h is the starting height. Now either factor or quadratic equation, whichever is easier for you.
Remember that the ball is on the ground when h(t)=0 since that is the height. There will be two zeros, one is a negative number so would be before you kicked the ball, the other one will be when the ball comes back down.
Answer:
40x = 1800 +25x
Step-by-step explanation:
5(3-6x)=4(3x+7)+5x
x= - 13/47
I=<4 over theproduct 1/8 so thats your answer bye digger
There will be 9 students left at the prep rally after 2 hours.
After 30 minutes
- Total Number of students = 729
- 2/3 of 729 = 486
- Number of students left = 729 - 486 = 243
After 1 hour:
- 2/3 of 243 = 162
- Number of students left = 243 - 162 = 81
After 1 hour 30 minutes :
- 2/3 of 81 = 54
- Number of students left = 81 - 54 = 27
After 2 hours :
- 2/3 of 27 = 18
- Number of students left = 27 - 18 = 9
Therefore, the Number of students left after 2 hours will be 9.
