The expression for the cubic function f is -5x^3 + 20x^2 - 25x.
To find an expression for a cubic function f(x) given specific values, we can start by using the general form of a cubic function: f(x) = ax^3 + bx^2 + cx + d.
We are given three points on the graph of the function: (5, 300), (-5, 0), and (0, 0), as well as (6, 0) which gives us a fourth point.
Substituting the x and y values into the equation, we get the following system of equations:
For point (5, 300):
300 = a(5^3) + b(5^2) + c(5) + d
For point (-5, 0):
0 = a(-5^3) + b(-5^2) + c(-5) + d
For point (0, 0):
0 = a(0^3) + b(0^2) + c(0) + d
For point (6, 0):
0 = a(6^3) + b(6^2) + c(6) + d
Simplifying these equations, we obtain a system of linear equations in terms of a, b, c, and d. Solving this system will give us the coefficients for the cubic function.
After solving the system, we obtain the expression for the cubic function:
f(x) = -5x^3 + 20x^2 - 25x

For each of the three mystery securities, I provide you with their monthly returns over the period from 1995-2014 (note that these are raw returns and thus are NOT in excess of the risk-free rate). I also provide you with the following other return series: Mkt_RF = return of value-weighted U.S. stock market minus 1-month U.S. Treasury Bill rate; SMB = return of small stocks minus the return of big stocks (based on market capitalization); HML = return of high book-to-market stocks (value) minus low book-to-market stocks (growth); RF = 1-month U.S. Treasury Bill rate. All of this data is contained in the spreadsheet ThreeMysterySecurities.xlsx, which you will use for this assignment.
Question 1
1A: Calculate the average raw return and the average excess return of Mystery Security #1. (4 points)
1B: Estimate a CAPM regression for Mystery Security #1 and report the CAPM alpha, CAPM beta, and R-squared of the CAPM regression. (6 points)
1C: Estimate a 3-Factor Model regression for Mystery Security #1 and report the 3-Factor alpha, 3-Factor market beta, 3-Factor size beta, 3-Factor value beta, and R-squared for the 3-Factor Model. (10 points)
1D: What is the identity of Mystery Security #1? You can at least describe some of the key characteristics of the Mystery Security #1. (3 points)
1A: To calculate the average raw return and average excess return of Mystery Security #1, we need to use the provided data for Mystery Security #1 and the risk-free rate (RF) as follows:
Average raw return of Mystery Security #1 = (sum of monthly returns of Mystery Security #1 from 1995-2014) / 240
Average excess return of Mystery Security #1 = average raw return of Mystery Security #1 - RF
1B: To estimate a CAPM regression for Mystery Security #1, we need to regress the monthly excess returns of Mystery Security #1 on the excess returns of the market (Mkt_RF). The CAPM alpha is the intercept of this regression, the CAPM beta is the slope coefficient of the market excess returns, and the R-squared of the regression measures the proportion of the variation in Mystery Security #1's excess returns that is explained by the market excess returns.
1C: To estimate a 3-Factor Model regression for Mystery Security #1, we need to regress the monthly excess returns of Mystery Security #1 on the excess returns of the market (Mkt_RF), the excess returns of small stocks minus big stocks (SMB), and the excess returns of high book-to-market stocks minus low book-to-market stocks (HML). The 3-Factor alpha is the intercept of this regression, the 3-Factor market beta is the slope coefficient of the market excess returns, the 3-Factor size beta is the slope coefficient of the SMB excess returns, the 3-Factor value beta is the slope coefficient of the HML excess returns, and the R-squared of the regression measures the proportion of the variation in Mystery Security #1's excess returns that is explained by the three factors.
1D: To identify the identity of Mystery Security #1, we would need more information. However, based on the CAPM and 3-Factor Model regressions, we can make some inferences about the key characteristics of Mystery Security #1. For example, the CAPM beta and 3-Factor market beta can give us an indication of Mystery Security #1's sensitivity to overall market movements, while the 3-Factor size beta and 3-Factor value beta can give us an indication of Mystery Security #1's sensitivity to small stocks and high book-to-market stocks, respectively.

QUESTION 1 · 1 POINT dy dy dx dy du du da Given y = f(u) and u = g(x), find by using Leibniz's notation for the chain rule: dx y=5u4 +4 u= -3.22 Provide your answer below: =
Using Leibniz's notation for the chain rule \(\frac{dy}{dx}\)= 540x⁸.
To find \(\frac{dy}{dx}\) using Leibniz's notation for the chain rule, we have:
y=f(u)=5u⁴+2
u=g(x)=3x³u
Let's start by finding \(\frac{dy}{du}\) and \(\frac{du}{dx}\) individually:
1. \(\frac{dy}{du}\):
To find \(\frac{dy}{du}\), we differentiate y with respect to u while treating uas the independent variable:
\(\frac{du}{dy}\) =d/du(5u⁴+2) = 20u³
2. \(\frac{du}{dx}\) :
To find \(\frac{du}{dx}\) , we differentiate u with respect to x:
\(\frac{du}{dx}\) = d/dx(3x³)=9x²
Now, we can apply the chain rule by multiplying \(\frac{dy}{du}\) and \(\frac{du}{dx}\) to find \(\frac{dy}{dx}\)
\(\frac{dy}{dx}\) = \(\frac{dy}{du}\) * \(\frac{du}{dx}\) = (20 u³)* (9x²)
Substituting u=3x³:
\(\frac{dy}{dx}\) = (20(3x³)³)⋅(9x²)
Simplifying:
\(\frac{dy}{dx}\) = 540 x⁸
Therefore, \(\frac{dy}{dx}\)=540x⁸ using Leibniz's notation for the chain rule.

the selling price of the blcycle. Round to
the nearest cent. (Answer please)
The selling price of the bicycle, with a wholesale cost of $98.75 and a 33.3% markup, is approximately $131.59.
To find the selling price of the bicycle, we need to calculate the markup amount and add it to the wholesale cost. The markup amount can be calculated as a percentage of the wholesale cost. In this case, the markup percentage is 33.3% of $98.75.
Markup amount = 33.3% of $98.75
= 0.333 * $98.75
= $32.84 (rounded to the nearest cent)
Now, to find the selling price, we add the markup amount to the wholesale cost:

let g be the function defined by g(x)=∫x−1(−12 cos(t 3 2t))ⅆt for 0
Let g be the integral function defined by g(x) = ∫x-1 (-1/2 * cos (t³ / 2t)) dt for x = 0, g is g(x) = -1/2(x-1 * sin(t³/2t) - x-1 * cos(t³/2t)).
To solve this integral, we need to use the substitution method. We will let u = t/2t, du = 3t/2 dt.
Thus, the integral becomes:
g(x) = -1/2 * ∫x-1 cos(u) du
Using integration by parts, we get:
g(x) = -1/2(x-1 * sin(u) + ∫x-1 sin(u) du).
After integrating the second part, we obtain the final result:
g(x) = -1/2(x-1 * sin(u) - x-1 * cos(u))./2t
we subtitute the value of u to get:
g(x) = -1/2(x-1 * sin(t³/2t) - x-1 * cos(t³/2t)).

If y=a^n; then change in y/y= n(change in a/a)
So the final expression is: (change in y/y) = n (change in a/a).
We can start by taking the natural logarithm of both sides of the equation:
ln(y) = ln(aⁿ)
Using the rule that ln(aⁿ) = n ln(a), we can simplify this to:
ln(y) = n ln(a)
Next, we can take the derivative of both sides with respect to a:
d/d(a) ln(y) = d/d(a) (n ln(a))
Using the chain rule, we can simplify the right-hand side to:
d/d(a) ln(y) = n (1/a)
Now, we can multiply both sides by a/y:
a/y * d/d(a) y = n(a/y) * (1/a)

When we are computing a simple linear regression line, there are certain conditions that must be met for this model to be valid. One of these conditions is the equal spread condition. Which of these answers best explains how we check to make sure that this condition is met? a. Make sure there is similar spread around the sample mean of x. b. Make sure there is similar spread around the line at each value of x.
c. Make sure that there is similar spread around the sample mean of y. d. Make sure all outliers are only below the line.
The answers that best explains how we check to make sure that this condition is met is: c. Make sure there is similar spread around the sample mean of y.
How we check to make sure that this condition is met?The equal spread condition states that the residuals (differences between the actual and predicted values of y) should have roughly equal variance at each value of x.
To check if this condition is met, we examine the residual plot, which is a scatterplot of the residuals versus the independent variable x. If the spread of residuals around the mean is roughly equal for all x, then the equal spread condition is satisfied.
Therefore the correct option is C.

The set b = (1 + t2,t + t21 + 2t + t2) is a basic for p2. Find the coordinate vector of p(t)=1 + 4t + 7t2 relative to B.
The coordinate vector of p(t) = 1 + 4t + 7t² relative to B is (2, 6, -1).
What is the coordinate vector?
A coordinate vector is a numerical representation of a vector that explains the vector in terms of a specific ordered basis. A simple example would be a position in a 3-dimensional Cartesian coordinate system with the basis being the system's axes.
Here, we have
Given: The set b = (1 + t², t + t², 1 + 2t + t²) is a basic for P₂.
Now, let coordinate vector of P(t) = 1 + 4t + 7t² relative to B is (C₁, C₂, C₃).
Then,
1 + 4t + 7t² = C₁(1 + t²) + C₂(t + t²) + C₃(1 + 2t + t²)
(C₁+C₃) + ( C₂+2C₃)t + (C₁+C₂ +C₃)t² = 1 + 4t + 7t²
C₁+C₃ = 1
C₂+2C₃ = 4
C₁+C₂ +C₃ = 7
Now, to find C₁, C₂, C₃ we solve the system.
The augmented matrix of the given system is:
= \(\left[\begin{array}{ccc}1&0&1|1\\0&1&2|4\\1&1&1|7\end{array}\right]\)
Now, we apply row reduction and we get
R₃ = R₃ - R₁
= \(\left[\begin{array}{ccc}1&0&1|1\\0&1&2|4\\0&1&0|6\end{array}\right]\)
R ⇔ R
= \(\left[\begin{array}{ccc}1&0&1|1\\0&1&0|6\\0&1&2|4\end{array}\right]\)
R₃ = R₃ - R₁
= \(\left[\begin{array}{ccc}1&0&1|1\\0&1&0|6\\0&0&2|-2\end{array}\right]\)
R₃ = 1/2R₃
= \(\left[\begin{array}{ccc}1&0&1|1\\0&1&0|6\\0&0&1|-1\end{array}\right]\)
R₁ = R₁ - R₃
= \(\left[\begin{array}{ccc}1&0&0|2\\0&1&0|6\\0&0&1|-1\end{array}\right]\)
C₁ = 2, C₂ = 6, C₃ = -1

Step-by-step explanation:
We can use trigonometry to solve this problem. Let's draw a diagram:

We want to find the height of the clock tower, which is CE. We have the angle of elevation ACD, which is 19 degrees, and the distance AB, which is 100 m. We can use tangent to find CE:
tan(ACD) = CE / AB
tan(19) = CE / 100
CE = 100 * tan(19)
CE ≈ 34.5 m (rounded to 1 decimal place)
Therefore, the height of the clock tower is approximately 34.5 m.
