Step-by-step explanation:
Answer:
(i)
time to bounce in one direction is 0.75 sec
(ii)
time to bounce in other direction is 1.5 sec
(iii)
total time is 2.25 sec
Step-by-step explanation:
Time to bounce in one direction:
we can see that height is increasing till t=0.75sec
so, time to bounce in one direction is 0.75 sec
Time to bound in other direction:
we can see that height is decreasing from t=0.75 to 2=2.25 sec
so, time to bounce in other direction is 2.25-0.75
=1.5 sec
Total time :
We know that
total time = (time to bounce in one direction)+(time to bounce in other direction)
now, we can plug values
total time =0.75+1.5=2.25 sec
Answer:
x= 500 y= 1500
Step-by-step explanation:
Isolate x or y in the first equation
Isolating for x would be x= -y+2000
Substitute X=-y+2000 into equation 10x+20y=35000
10(-y+2000)+20y=35000
Exapnd the equation above and you should get y=1500
Same steps for finding x by isloating for y
2x+y-3z=12
2x=4z-y
x=2z-y/2
