Given:
The sequence is
436, 218, 109, 54.5, 27.25,...
To find:
The explicit formula for the given sequence.
Solution:
We have,
436, 218, 109, 54.5, 27.25,...
It is a GP because the two consecutive terms have common ratio.
Here,
First term : a=436
Common ratio : d =
=
=
Now, the explicit formula for a GP is
Where, a is the first term and r is the common ratio.
Putting a=436 and r=0.5, we get
Therefore, the correct option is c.
Since a cube is essentially 6 squares, and the base, length, and height is ∛(volume)=∛(27)=3 due to that a cube is base*width*height, with each being the same. Each square is 3*3=9 square centimeters. 6 equal squares are 9*6=54 square centimeters. which is 1 cube. 54*2=108, 54*3=162, and we have 6*27=162 square inches, meaning that we have 3 cubes!
A. The district office has to be at (2,3) because the x-value has to be above (2,2) and the y-value has to be beside (-4,2) in order to make a rectangle.
B. The length is 12 units (24 miles) and the width is 2 units (4 miles).
C. The perimeter is 2l+2w = 56 miles
D. The area is l*w = 96
Hope this helps
