We know that
The sum of exterior angles of any polygon is 360 degrees.
Each exterior angle of a regular polygon = 360/n
where n is the number of sides.
<span>So
n = 360/20 = 18
</span>
the answer is the option
<span>b.18 </span>
Answer:
Daniel (now) is 3 years old, (2 years ago) is 1 year old.
Kevin (now) is 6 years old, (2 years ago) is 4 years old.
Step-by-step explanation:
Now:
-Kevin: k = d + 3
-Daniel: d
2 years ago:
-Kevin: k - 2 = 4(d - 2)
-Daniel: d - 2
We have the equation:
(k - 2) + 2 = k
4(d - 2) + 2 = d + 3
4d - 8 + 2 = d + 3
3d - 6 = 3
3d = 9
d = 3
k = d + 3 = 3 + 3 = 6

Answer:
rate of change: 4
initial value: -1
Step-by-step explanation:
The rate of change is the number of units in the y-direction for each unit in the x-direction. As x goes from 0 to 1 (1 unit change), y goes from -1 to 3 (4 unit change). Hence the rate of change is 4.
The "initial value" is the y-value where the graph crosses the y-axis. It is -1, as we observed when computing the rate of change.
6.66666666667% you divide 120 by 18 that = 6.66666666667 and add a %
