Review the graph of a piecewise function. On a coordinate plane, a line starts at open circle (0, negative 1) and goes to open circle (negative 2, negative 3). It then curves up through (negative 5, 2). A curve starts at closed circle (0, 3) and curves down and approaches x = 1 into quadrant 4. Another curve starts at closed circle (2, 3) and curves down and approaches x = 1 in quadrant 4. A horizontal line goes from closed circle (2, 3) to (5, 3). Which list represents all values of x for which the function has a discontinuity? 1 0 and 1 –2 and 1 –2, 0, and 1

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 )
