Which of the below is not one of the properties of logarithms? a; the log of a product (ab) is equal to the addition of log a nad log b b; the log of the sum of a and b is equal to the sum of the log of a and the log of b c; the lof of the quotient of a and b is equal to the log of a minus the log of b d; the log of the quantity a raised to b is equal to the product of b and the log of a

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 )
