Answer:
<em>1.0625 seconds</em>
Step-by-step explanation:
Given that:
Initial velocity of Belinda, 
Height in feet of Belinda above the trampoline is given as the formula:
Where 
is the time in seconds.
To find:
Time taken by Belinda to come back to trampoline = ?
Solution:
When Belinda will come back to trampoline, the height will be zero.
Putting 
We have the equation as:
Therefore, the answer is: <em>1.0625 seconds</em>

The sum of the interior angles of a polygon is (n-2)*180, n being the number of sides.
a nonagon has nine sides, so the total of interior angles is (9-2)*180=7*180
this is a regular nonagon, so each interior angle has the same degrees:
7*180/9=7*20=140
the exterior angle=180-the interior angle=180-140=40
40 is the correct answer.
