After Scar took over the animal kingdom and Simba ran away, the population of animals (besides the hyenas) was decreasing at a rate of approximately 20% per year. Before this happened, there were approximately 2000 animals in the main kingdom. Write a function to represent the population of the kingdom after x years. What would the population be after seven years?

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 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 )
