Which of the following shows the mixed numbers in order from least to greatest explain your answer a. 2 3/4, 2 5/8, 2 7/10 b. 2 5/8, 2 7/10, 2 3/4 c. 2 5/8, 2 7/10, 2 3/4 d. 2 7/10, 2 3/4, 2 5/18

B. 2 5/8, 2 7/10, 2 3/4

To convert the fractions to decimals, (by dividing the numerator by the denominator,) the 2 5/8 = 2.625, 2 7/10 = 2.7, and 2 3/4 = 2.75. For example, since the "2" in 2 5/8 is a whole number, it would go in front of the decimal point (2.0), then you just divide 5 by 8.

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}
