Given:
The given arithmetic sequence is:
To find:
The recursive formula of the given arithmetic sequence.
Solution:
We have,
Here, the first term is -3. So, .
The common difference is:
The recursive formula of an arithmetic sequence is:
Where, d is the common difference.
Putting , we get
Therefore, the recursive formula of the given arithmetic sequence is , where .
Answer:
.6,5.6
Step-by-step explanation:
The angle in the diagram is 90 degrees, while the circumferential angle is 360 degrees, so 1/4 of the circle is blank, and the shaded region is 3/4 of the circle. The area of the circle is pi*r^2=36pi cm^2. While the region is only three quarters of it, so the area is 3/4*36pi=27pi cm^2.
Answer:
-538.67 (2 d.p)
Step-by-step explanation:
4x +1612 = x - 4
4x -x = -1616
x = (-1616)÷3= -538.67 (2d.p)
