Given u1 = 56 and un = 0.7un-1, find s12. round to the nearest hundredth a) 181.39 b) 184.08 c) 185.32 d) 186.66

Step-by-step explanation:

      form a sequence exhibiting the following property :

On rewriting, ⇒ Ratio of consecutive terms is a constant. Hence, the sequence is a Geometric Progression.

       The ratio is the common ratio . First term = .

       Sum of terms of a Geometric progression is given by

when .

∴ to the nearest hundreth is 184.08

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
