Find all the real zeros of the polynomial $$P(x) = x^3 - 3x^2 - 11x + 5.$$ Enter the real zeros as a comma-separated list: $$5, -1 + \sqrt{2}, -1 - \sqrt{2}$$ Note: Give exact answers; no decimals. If needed, enter square root as sqrt, e.g. the square root of 2 should be entered as sqrt(2). When $$x \rightarrow \infty, P(x) \rightarrow$$ When $$x \rightarrow -\infty, P(x) \rightarrow$$ Note: If your answer is $$\infty$$, enter infinity ; if your answer is $$-\infty$$, enter -infinity .

FRQ 1 A graphing calculator is required for the following problem. Water is flowing into and out of a small reservoir. The total amount of water can be modeled by \( R \), where \( R(t)=20-15 \sin \left(\frac{t^{2}}{25}\right) \) cubic feet, \( t \) is measured in hours, and \( 0 \leq t \leq 8 \). a) What is the average rate of change of \( R \) over the interval \( 0 \leq t \leq 8 \) ? Indicate the correct units of measure. b) Find the value of \( R^{\prime}(2) \). Using correct units, interpret the meaning of the value in the context of the problem. c) Find all times \( t \) for which the rate at which the amount of water in the reservoir is changing is equal to the average rate of change of \( R \) over the interval \( 0 \leq t \leq 8 \). d) The reservoir can hold a maximum of 30 cubic feet. At what time after \( t=8 \) hours will the reservoir reach its capacity?

We consider the same three data points (x1=-0.6, x2=1.4, x3=3.0) from the KMean problem, but we apply EM with two soft clusters. We consider the two final \mu values (\mu 1 and \mu 2: \mu 1<\mu 2). Which of the following statements are true? We consider the same three data points (x1=-0.6, x2=1.4, x3=3.0) from the KMean problem, but we apply EM with two soft clusters.

below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. MgBr Will the first product that forms in this reaction create a new C-C bond? MgBr OH Yes No Will the first product that forms in this reaction create a new C-C bond? Yes No X 5
