Gevaluate lim h → 0 (1 + h)9 − 1 h . hint: this limit represents the derivative of a function f at a given point a. find f and a, and then evaluate the derivative.

Write , and recall that for a differentiable function , the derivative at a point  is given by



which would suggest that for this limit, and . We have , and so the value of the limit would be .

Can you tell us the question

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 )
