The bottom of Ignacio's desktop is 74.5cm from the floor. Ignacio sits in his adjustable chair, and the tops of his legs are 49.3 from the floor. Each clockwise rotation of the knob on the chair raises Ignacio's legs by 4.8cm. Write an Inequality to determine the number of clockwise rotations, r, Ignacio could make with the knob, without his legs touching the desk? What is the solution set of the Inequality?

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

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.  

step-by-step explanation:

no solution.
