an outdoor swimming pool loses 0.05% of its water volume
every day it is in use, due to losses from evaporation
and from excited swimmers who splash water. a system is
available to continually replace water at a rate of g gallons
per day of use.
(a) find an expression, in terms of g, for the equilibrium
volume of the pool. sketch a few graphs for the volume v(t),
including all possible types of solutions.
(b) if the pool volume is initially 1% above its equilibrium
value, find an expression for v(t).
(c) what is the replacement rate g required to maintain
12,000 gal of water in the pool?

Which facts are true for the graph of the function below? check all that apply. f(x) = log8 x

Jeffery conducted a survey in his school and found that 30 of the 50 eighth grade students' favorite subject is mathematics. based on the results, jeffery concluded that out of the 200 students in his school, 120 students' favorite subject is mathematics. select the statement that is true about jeffery's conclusion. a. jeffery's conclusion is not valid because the sample was biased since only 200 students were surveyed. b. jeffery's conclusion is valid because the sample was random since all of the students were eighth grade students. c. jeffery's conclusion is valid because the sample was random. d. jeffery's conclusion is not valid because the sample was biased since all of the students were eighth grade students.
