PartII:LetD={(x, y)|2x2 +y2 ≤16}(x, y)insideor on the ellipse 2x2 + y2 = 16. Find the absolute maximum and the absolute minimum values of f(x, y) on D, and specify the points (x, y) where each occurs. Justify your work carefully, and make your reasoning clear.

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 )
