Answer:
The radius of convergence is half of the length of the interval of convergence. If the radius of convergence is R then the interval of convergence will include the open interval: (a − R, a + R). To find the radius of convergence, R, you use the Ratio Test.
Answer:
BC ~ DE because of similar transformation
Step-by-step explanation:
ABC and DEF are not similar transformations the second one is wrong, the third one is wrong because. The last one ios right because by deduction it is.
Answer:
Step-by-step explanation:
The window consists of a large square and 4 smaller triangles on the outside. The side length of this square is marked as 10, and therefore the area of this square is 
.
The area of a triangle is given by 
. Since the problem states that the overlapping squares are congruent, both legs of the triangle will be 
and intersect at a 
angle.
Thus, the sum of all four triangles is 
.
Therefore, the area of the window is:
Answer:
120°
Step-by-step explanation:
Sum of angles = (n-2)180°, where n is the number of sides.
This is a hexagon, so n=6.
Sum of angles = (6-2)180° = 720°
Each interior angle = 720°/6 = 120°
