Solve for s: 6.49s + 8.32 = 27.79

s = 3

Step-by-step explanation:

STEPS FOR SOLVING LINEAR EQUATION

6.49s+8.32=27.79

Subtract 8.32 from both sides.

6.49s=27.79−8.32

Subtract 8.32 from 27.79 to get 19.47.

6.49s=19.47

Divide both sides by 6.49.

s=

6.49

19.47

Expand  

6.49

19.47

 by multiplying both numerator and the denominator by 100.

s=

649

1947

Divide 1947 by 649 to get 3.

s=3

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}
