The Miller family wants to join a public swimming pool that charges a fee of $25.00 per year and then $3.00 for each visit. A. Draw a graph to show the yearly cost to the Miller family.
B. Can the cost be represented by linear function? why or why not?
C. Write a function to model the yearly cost to the Miller family. Make sure to define variables.
D. If the pool decided to charge $3.50 per visit, how would you graph change?

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
