Centerville is the headquarters of greedy cablevision inc. the cable company is about to expand service to two nearby towns, springfield and shelbyville. there needs to be cable connecting centerville to both towns. centerville is located at (10,0) in the xy-plane, springfield is at (0,3), and shelbyville is at (0,-3). to save on the cost of cable, greedy cablevision wants to arrange the cable in a y-shaped configuation, running cable from centerville to some point (x,0) on the x-axis where it then splits into two branches, one going to springfield and one to shelbyville. find the location (x,0) that will minimize the amount of cable between the 3 towns and compute the amount of cable needed. justify your conclusion by answering the following questions.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

the probability that a bird is green (.30) is true
