Given polynomial function (f) and a zero of (f), find the other zeros. 1) f(x) = 10x^3 - 81x^2 + 71x +42 ; 7

2) f(x) = 5x^3 - x^2 - 18x + 8 ; -2

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 )

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
