6 0

Tangent is a line that touches the circle at one point going infintiely in both directions

chord is a line that goes from one side of the circle to the other and stays inside the circle, an example would be the diameter which is the longest chord in the circle

secant is a line that goes through the circle at 2 points, it's like a chord but it extends outside the circle

arc length is a section of the circumference
it's like the length of the crust when you cut a slice of pie or the crust of a pizza

Step-by-step explanation:

Linear Modeling

Some situations in real life are bound to be modeled as mathematical functions. A model allows scientists and analysts to take decisions based on predicted values coming from those models.

To construct them we usually take or measure values of the variables of interest and find the general equation of the model. In this case, we'll find the relation between the service costs (y) of a cell phone provider and the number of months (x).

There are three points available: ( 1 , 72.99 ) , ( 2 , 101.44 ) , ( 3 , 129.89 ) and we only need two to find a function of the form

$y=c+d(x-1)$
