The graph represents the cost of catering a dinner as a function of the number of guests. On a coordinate plane, a graph titled Dinner Catering Cost shows Guests Served on the x-axis and Total cost in dollars on the y-axis. A piecewise function has 3 lines. The first line has an open circle at (0, 100) and goes up to a closed circle at (40, 600). The second line has an open circle at (40, 700) and goes up to a closed circle at (80, 1300). The third line has an open circle at (80, 1600) and goes up to (100, 2000).

What is the catering cost for a dinner with 40 guests?
$400
$600
$700
$800

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 )
