The typical daily energy use of a household is described by a function f : [−12, 12] → [0, ∞). The value of f(x) is the consumption rate at given time x. Both points x = −12 and x = 12 of the domain correspond to 3am so f(12) = f(−12). It is also known that 9am and 9pm (x = −6 and x = 6, respectively) are local maxima of the consumption rate. In this question we model the rate by a polynomial of degree 4 that is f(x) = a4x4 + a3x3 + a2x2 + a1x + a0and assume that the total energy consumption during the day equals 24.

(a) Write a linear system of equations describing the following properties: f(12) = f(−12), [4]x = −6, 6 are stationary points of f and the total energy consumption is 24.

A website promoting the use of alternative energy vehicles and hybrid technologies claims that, \"A typical automobile in the USA uses about 500 gallons of gasoline every year, producing about 5 tons of carbon dioxide.\" To determine the truth of this statement, calculate how many tons of carbon dioxide are produced when 500.0 gallons of gasoline are combusted. Assume that the primary ingredient in gasoline is octane, C8H18(l), which has a density of 0.703 g·mL^ –1 HINT: Generate a balanced...

Suppose that the distribution of wind velocity, X, is described by the probability density function f(x) = (x/σ^2)e^-(x^2/ 2(σ^2)) , x ≥ 0. Suppose that for the distribution of wind velocity in Newcastle, measured in km/hr, σ^2 = 100. (a) In task 1, you showed that the quantile function for this distribution is given by: Q(p) = σ (−2 ln(1 − p))^(1/2), 0 ≤ p < 1 Use this quantile function to generate 100,000 random values from this distribution (when...

Some hints: use the definition: f is a function iff a = b implies f(a) = f(b) and recall that in informal proofs we show an implication by assuming the if part of the implication, and then deducing the then part of the implication. The base case will show that a = b implies f(a) = f(b) when f(x) = c0 (a constant function). The inductive case will assume a = b implies f(a) = f(b) for degree k, and...
