Answer:
Step-by-step explanation:
To find recursive formula in a geometric sequence, you need to first find the common ratio, 'r', between the numbers in the given data set. From the data set given, it appears that the previous number is multiplied by 
so, r = .
Recursive formula involves two other variables:
the 
term in the sequence
=the term before the term
So, the final formula is:
Answer:
<h2>54 in²</h2>
Step-by-step explanation:
Look at the picture.
The edge of the cube is equal to the diagonal of the sphere.
Therefore, the length of the cube's edge is 3 inches.
The formula of a surface area of a cube:
Substitute a = 3 in:
No it’s not a rectangle because the diagonals are not congruent
Set both equations equal.
35+.1x=25+.15x
10+.1x=.15x
10=.5x
20=x
20 miles is the answer.
Answer:
<h2>3x - 2</h2>
Step-by-step explanation:
2(3x-1)-3x = 6x - 2 - 3x
= (6x - 3x) - 2
= 3x - 2
