A tank contains 30 lb of salt dissolved in 500 gallons of water. A brine solution is pumped into the tank at a rate of 5 gal/min; it mixes with the solution there, and then the mixture is pumped out at a rate of 5 gal/min. Determine A(t), the amount of salt in the tank at time t, if the concentration of salt in the inflow is variable and given by cin(t) = 2 + sin(t/4) lb/gal. A(t) = Incorrect: Your answer is incorrect. lb Without actually graphing, conjecture what the solution curve of the IVP should look like. Then use a graphing utility to plot the graph of the solution on the interval [0, 300].

Two quadratic functions are represented below.Which sentence correctly compares the two functions?A. The axis of symmetry of the graph of g(x) is to the right of the axis of symmetry of the graph of f(x) because f is symmetric about x = 0, g is symmetric about x = -3, and 0 > -3.B. The value of g(x) is greater than that of f(x) at x = -2 because g(-2) = 0, f(-2) = -1, and 0 > -1.C. The minimum value of f(x) is greater than the maximum value of g(x) because f(0) > g(-3).D. The axis of symmetry of the graph of g(x) is to the left of the axis of symmetry of the graph of f(x) because g is symmetric about x = 1, f is symmetric about x = 3, and 1 < 3.

WILL MARK BRAINLEST! HELP ASAP Pedro has a spinner with 4 sections numbered 1 through 4. Pedro spins the spinner 100 times and records the results. He calculates the relative frequency of each outcome. Outcome 1 2 3 4 Relative Frequency 0.24 0.25 0.26 0.25 Which statements about Pedro's experiment are true? Select each correct answer. A uniform probability model is a good model to represent probabilities related to the numbers generated in Pedro's experiment. The theoretical probability that any one number is chosen is likely 0.20. It is likely that the spinner is fair. The relative frequencies in the table are very differenT.

David estimated he had about 20 fish in his pond. A year later, there were about 1.5 times as many fish. The year after that, the number of fish increased by a factor of 1.5 again. The number of fish is modeled by f(x)=20(1.5)^x.Create a question you could ask that could be answered only by graphing or using a logarithm.

Consider a bag that contains 220 coins of which 6 are rare Indian pennies. For the given pair of events A and B, complete parts (a) and (b) below. A: When one of the 220 coins is randomly selected, it is one of the 6 Indian pennies. B: When another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 Indian pennies. a. Determine whether events A and B are independent or dependent. b. Find P(A and B), the probability that events A and B both occur.
