Beta = Correlation x (Variance of Z)^0.5 / (Variance of Market)^0.5
Beta = 0.18 x (0.3185)^0.5 / (0.0282)^0.5
Beta = 0.604927
CAPM equation:
Expected return = Risk free rate + Beta x (Market return - Risk free rate)
Expected return = 3.2% + 0.604927 x (9.9% - 3.2%)
Expected return = 7.25% is the answer.
Portfolio return refers to the return or loss realized on an investment portfolio that includes multiple types of investments. The portfolio is intended to provide returns based on the defined objectives of the investment strategy and the risk tolerance of the type of investor covered by the portfolio.
The basic formula for expected return is to multiply the weight of each asset in the portfolio by the expected return and then add up all these numbers. In other words, the expected return of a portfolio is a weighted average of the returns of the individual components.

The projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s2.
An object is launched at an initial velocity of 19.6 meters per second from an initial height of 24.5 meters. Which equation can be used to find the number of seconds it takes the object to hit the ground?
A. 0 = –4.9t2 + 19.6t + 24.5

m∠P + m∠Q + m∠R = 180°
QU ≅ RS

Option E: PT, QU, and RS intersect at the same point.
How to find the true statements of the triangle?1. m∠Q = m∠R: This is not true because there is no indication that the angles are equal.
2.The length of QU is half the length of RP: This is not true because there is no length given to show that measurement.
3. m∠P + m∠Q + m∠R = 180°:

How to determine the other parallel side?The given parameters are:
Midsegment= 2x
One parallel side = x
The midsegment is calculated as:
Midsegment = 0.5 * (sum of parallel sides)
So, we have
2x = 0.5 *(x + Other side)
Divide by 0.5
4x = x + Other side

If ABC is reflected across the y-axis, what are the coordinates of C?
A. (6,-3)
B. (3,-6)
C. (-6,-3)
D. (-6,3)
Answer:
Step-by-step explanation:
The correct answer would be C (-6,3). The y axis is the bold line going up and down on the middle of the page. If you were able to pick up triangle and flip it over the y axis. Point C would land at (-6,3).
Also, you can see that point C is six spaces to the right of the y axis. That means when we flipped it over the axis, it will now be six paces to the right of the y axis. Since the point did not go up or down when you flipped it. It is still 3 spaces above the x axis.
Answer:
D (-6, 3)
Step-by-step explanation:
the point C is originally (6, 3).
that means the x coordinate is 6, the y coordinate is 3.
now, if we reflect (= mirror) that point across the y axis, that means we mirror it to the other side of the y axis.
the y axis is the vertical coordinate axis in the middle of the graph.
so, what is going to happen to the point ?
will the y coordinate change ? no. the point will move over to the other side of the y line in the same "height" as before. nothing will move it higher or lower.
so, it will keep the same y coordinate : 3.
will the x coordinate change ? oh, yes. because the point will move from the right of the y axis to the left of the y axis. and it will be the same distance to the left as it was originally to the right.
so, +6 turns into -6 (as the y axis represents x=0).

If the parent function is \root(3)(x), describe the translation of the function y=\root(3)(x+4)-3
The parent function moves 4 units right and 3 units down. This is a translation by the vector.

Transformation [tex]\sqrt[3]{x}[/tex] maps onto [tex]\sqrt[3]{x+4} -3[/tex] . Take f(x) = [tex]\sqrt[3]{x}[/tex] and f(x+4)=[tex]\sqrt[3]{x+4}[/tex].
f(x) = [tex]\sqrt[3]{x}[/tex]
f(x+4)=[tex]\sqrt[3]{x+4}[/tex]
f(x+4) - 3=[tex]\sqrt[3]{x+4}[/tex] - 3
Analyze the function to see the translations. f(x-4) corresponds to a horizontal translation 4 units in the positive 'x' direction. f(x)-3 corresponds to a vertical translation 3 units in the negative 'y' direction.
Hence, the parent function moves 4 units right and 3 units down. This is a translation by the vector.

Determine the equation of the parabola whose graph is given below. Write your answer in General Form. A parabola on a coordinate plane.
The equation of parabola becomes y = -2/25(x-3)^2 + 4.
According to the statement
we have given a graph and from this graph we have to find the equation of parabola in the general form.
So,
we know that the equation of parabola in general form is
y = a(x-h)^2 +k - (1)
From the graph we have:
a point on the graph is (x,y) = (-2,2)
the vertex of the graph is (h,k) = (3,4)
Now, substitute these values in the equation number (1)
Then
y = a(x-h)^2 +k
2 = a(-2-3)^2 +4
2 = a(-5)^2 +4
2 = a(25) +4
25a = -2
a = -2/25.
Now put a = -2/25 and (h,k) = (3,4) in the equation(1).
Then
the equation of parabola becomes y = -2/25(x-3)^2 + 4

Draw the graph of the linear equation 2x – y + 1 = 0. From the graph find the values of h and k if the graph passes through the point (h,4) and (1/2 , k)
Answer + Step-by-step explanation:
2x – y + 1 = 0
We know that the graph of a linear equation is a line.
So ,in order to draw it we need to find two points A and B of the line
Afterward, we join A and B to get the graph.
2x – y + 1 = 0
If x = 0 → y = 1 ⇒ A(0 , 1) lie on the line AB (the graph)
If x = 1 → y = 3 ⇒ B(1 , 3) lie on the line AB
Now ,all we have to do is plotting A and B
on the coordinates plane ,then connecting then with a line.
According to the graph (check the attached image) :
If (h,4) ∈ line AB ⇒ h = 3/2
If (1/2 , k) ∈ line AB ⇒ k = 2
