Problem: The zeros of a parabola are -4 and 2, and (6, 10) is a point on the graph. Question: Which equation can be solved to determine the
value of a in the equation of the parabola?
A)6= a(10 -- 4X10 - 2)
B)6= a(10 + 4)(10-2)
C)10 = a(6 - 4/62)
D)10 = a(6 - 4X6 - 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 )
