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

Shelly and Terrence completed a different number of tasks in a game. Shelly earned 90 points on each task. Terrence's total poin
fgiga [73]
I'm thinking maybe x is supposed to represent the number of tasks completed because it states Shelly earned 90 points on each task.  Then when put together it may look like this, let's say there are 4 tasks= Ex.90 times the 4 tasks minus 20 points which would total the points Terrence's has earned. So i believe x is the total tasks. Hope I didn't make it confusing...

Which shows the equation below.....
sladkih [1.3K]
Option A is your answer. 

Subtract 3 from both sides to get zero on the right side of the equal sign. 

8 - 3 = 5. 

So that becomes your constant term in the equation.
