In each of the following expressions, c represents the original cost of an item

i . 0.90c
i . 0.10c
i . c- 0.10c

circle the expressions that represent 10% of the original cost. if more than one answer is correct, explain why expressions you use are equivalent.

i . 0.10c

Step-by-step explanation:

Just plug a random number, idk what number you'd choose. But my lucky number is 10 so 0.10 x 10 = 1 which is 10% of the original cost XD

yea..hope this helps! :D

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
