Vance sells between 300 and 310 items at a convention. He pays a one time $450 fee, and earns $15 commission for each item that he sells. The function p(i)=15i−450

represents Vance's convention earnings as a function of items sold.

What is the practical domain of the function?

A. all real numbers
B. 300≤i≤310
C. [300, 310]
D. all integers between 300 and 310 inclusive

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 )
