Coach Keller is having the last names of his players printed on their shirts. The lettering company charges a flat fee and a charge per letter. The table shows the total costs for 15, 20, 25, and 30 letters. Select the correct values to model the situation with a linear function. 1 2 3 4 Numbe Number of Letters, x 15 20 25 30 0.25 7 15 Cost (S), y 7 8.25 9.5 10.75 1 8.25 20 3.25 9.5 30 slope: = y-intercept: +b; b = linear function: y = xt What do the slope and y-intercept of the function represent?

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

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}

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.
