5. it is estimated that the annual cost of driving a certain new car is given by the formula
c = 0.35m + 2200
where m represents the number of miles driven per year and cis the cost in dollars. jane
has purchased such a car and decides to budget between $6400 and $7100 for next year's
driving costs. what is the corresponding range of miles that she can drive her new car?

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 )
