The wildflowers at a national park have been decreasing in numbers. there were 300 wildflowers in the first year that the park started tracking them. since then, there have been one fourth as many new flowers each year. create the sigma notation showing the infinite growth of the wildflowers and find the sum, if possible.

i chose c, but can someone check for me? : )

Choice C is correct. Do you need an explanation?

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 )
