Answer:
C. Three
Step-by-step explanation:
We want to solve the equation for n:
14,580 = 20,000(9/10)^n
14580/20000 = 729/1000 = (9/10)^n
(9/10)^3 = (9/10)^n . . . . . . write the left side as a cube
3 = n . . . . . . equate exponents
After year 3, the value will be $14,580.
_____
You can use logarithms to find n:
log(0.729) = n×log(0.9) . . . . . . taking the log of the 2nd line above
log(0.729)/log(0.9) = n = 3
<h3>SOLUTION :- </h3>
The Angle 257° will lie in the <u>Quadrant </u><u>III </u><u>.</u>
<h3>STEP-BY-STEP EXPLANATION :- </h3>
We have been asked to find .
• In which quadrant does the terminal side of the angle 257° lie ?
- As we know that in the first quadrant angle is from 0 to 90 ° .
In the second quadrant angle is from 90 to 180°.
In the third quadrant angle is from 180 to 270° .
In the fourth quadrant angle is from 270 to 360° .
<h3>Hence,The Angle 257 will lie in the third Quadrant .....</h3>

Vertices are formed when 2 sides come together on a polygon. So they are basically corners. The smallest amount of sides a polygon has is 3, which would be a triangle. And triangles have 3 corners, because with a triangle, each side touches the other two. So the minimum number of vertices needed to form a polygon would be 3.
