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:
d 13
Step-by-step explanation:
Subtracting means adding the opposite.
To subtract -4, you add the opposite of -4 which is 4, so you add 4.
9 - (-4) = 9 + 4 = 13
Answer: d 13
The line is passing through the y-axis at 3. The slope of the line is 3.
So your equation would be y = 3x + 3.
Now solve A through F to see which equation(s) matches the line.
A. y + 6 = 3(x + 3)
y + 6 = 3x + 9
y = 3x + 3
B. y + 6 = 3(x + 1)
y + 6 = 3x + 3
y = 3x - 3
C. y - 6 = 3(x - 3)
y - 6 = 3x - 9
y = 3x - 3
D. y - 6 = 3(x - 1)
y - 6 = 3x - 3
y = 3x + 3
E. y = 3x + 2
F. y = 3x + 3
Which letters equaled y = 3x +3?
A, D, and F.
The equations that describe the line are A, D, and F.
