Answer:
B. 40
Step-by-step explanation:
Given:
The given shape is nonagon.
It consist of 9 sides.
We need to find the value of exterior angle 'x'.
Solution:
Now we know that;
"The sum of the exterior angles of any polygon is 360 degrees."
Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles.
Since here there is Nonagon then there would be 9 exterior angles.
So measure of angle 'x' =
Hence The value of 'x' 40°.
Answer:
y=25600
y=100(2)^{2t}
y=252
Step-by-step explanation:
A bacteria culture starts with 100 bacteria and doubles in size every half hour.
where x represents the number of hours
(a) t= 4 hours
Plug in 4 for t and find out the number of bacteria y
25600 bacteria
convert 40 seconds into hour
40 divide by 60 =2/3
The graph is attached below
