Nolan began a savings account three years ago. he invested $100 at a 2% interest rate according to the equation vn = 100(1.02)x, where vn is the value of his account after x years. anias started an account today. she invested $100 at a 2% interest rate according to the equation va = 100(1.02)x–3, where va is the value of her account. let’s say anias started saving at the same time nolan did, three years ago. approximately how much money would she have had to invest to have the same amount of money she has now?

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 )
