Let d be the distance in feet of a race car from the starting line, and let t be the number of seconds since the race began. The distance d is a function of the time t and is represented by the function f, defined by : d = f(t) = 3.2t2 + 3t. (a) What is the meaning of f(7) – f(3)? (b) True or False: The race car’s average speed over the interval t = 3 seconds to t = 7 seconds is equal to 𝑓(3)+𝑓(4)+𝑓(5)+𝑓(6)+𝑓(7) . 5 (c) Compute the value of the race car’s average speed (i.e., the AROC for the function f) over the interval t = 3 to t = 7 sec. (d) Write a statement that best describes the meaning of average speed in this context.

List all solutions in $ (0, 2\pi) $: $ 2 \cos(x) - 1 = 0 $ • Give your answer in radians. • Separate multiple solutions with commas. • Do not use decimal approximations. Use 'pi' to represent $ \pi $. Use the periodicity of cosine to find at least 4 more solutions to the equation: • Solutions between 0 and $ 2\pi $ belong in the first answer. • Your four additional solutions should not be between 0 and $ 2\pi $.

5.78. The van der Waals equation of state (Equation 5.3-7) is to be used to estimate the specific molar volume $\tilde{V}$ (L/mol) of air at specified values of T(K) and P(atm). The van der Waals constants for air are a = 1.33 atm L²/mol² and b = 0.0366 L/mol. (a) Show why the van der Waals equation is classified as a cubic equation of state by expressing it in the form $f(\tilde{V}) = c_3 \tilde{V}^3 + c_2 \tilde{V}^2 + c_1 \tilde{V} + c_0 = 0$ where the coefficients $c_3$, $c_2$, $c_1$, and $c_0$ involve P, R, T, a, and b. Calculate the values of these coefficients for air at 223 K and 50.0 atm. (Include the units when giving the values.)
