A trampolinist steps off from 25 feet above ground to a trampoline 17 feet below. The function
h(t)=-1672 +25, where t represents the time in seconds, gives the height, in feet, of the trampolinist
above the ground as he falls. When will the trampolinist land on the trampoline?
The trampolinist will land on the trampoline after about
second(s)

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 )
