Kristen's financial advisor has given her a list of 8 potential investments and has asked her to select and rank her favorite four. In how many different ways can she do this?
The number of ways in which Kristen can rank her favorite four from 8 using permutations is 1680.
The permutation is a way of finding the number of ways of selecting a set of articles from a larger set of articles, with the order of selection being significant.
If we want to choose r items from n items, where the order of selection is significant, then we can find the number of ways of doing this using the permutation as follows:
nPr = n!/{(n - r)!}.
In the question, we are asked to find the number of ways Kristen can rank her favorite four investments from the 8 potential investments that her financial advisor has given her.
Thus, using permutations, we need to select 4 items from 8 items, with order of selection being significant.
Substituting n = 8, and r = 4 in the formula, we get:
8P4 = 8!/{(8 - 4)!}
= 8!/4!
= 5 * 6 * 7 * 8
= 1680.
Thus, the number of ways in which Kristen can rank her favorite four from 8 using permutations is 1680.

When beth was 9 years old, paul was 3 times younger than her. Now beth is 30 years old, how old is paul?.
Step-by-step explanation:
9÷3=3 so when beth is 30 you need to do 30-6 which is 24
When beth was 9, paul was 3 times younger = 9/3 = 3 years old.
Beth has gained 21 years since, so the age of paul is 3 + 21 = 24 years old.

Answer:
c = 14 in.
Step-by-step explanation:
We know from the 30-60-90 Triangle Theorem that the side opposite the 30° angle is x and the side opposite the 60° angle is x√3, so 7 must be x. We further know that according to the theorem, the side opposite the 90° or right angle (aka the hypotenuse) is 2x. Since x is 7 in the diagram, the length of the hypotenuse must be 14 in as 2 * 7 = 14.

the phasor form of the sinusoid 8 sin(20t 57°) is 8 ∠
The phasor form of a sinusoid represents the amplitude and phase angle of the sinusoid in complex number notation. In this case, the phasor form of \(8 sin(20t 57)\) would be 8 ∠57°. The amplitude, 8, is the magnitude of the complex number, and the phase angle, 57°, is the angle of the complex number in the complex plane.
In terms of amplitude and phase angle, a sinusoidal waveform is mathematically represented in phasor form. Electrical engineering frequently employs it to depict AC (alternating current) circuits and signals. A complex number that depicts the magnitude and phase of a sinusoidal waveform is called a phasor. The phase angle is represented by the imaginary component of the phasor, whereas the real part of the phasor represents the waveform's amplitude. Complex algebra can be used to analyse AC circuits using the phasor form, which makes computations simpler and makes it simpler to see how the circuit behaves.

Is the set of negative integers a commutative group under the operation of addition? if not, why not? select all that apply.
The set of negative integers is a commutative group under the operation of addition.
For given question,
We need to check whether the set of negative integers is a commutative group under the operation of addition.
We know that negative integers are whole numbers that have value less than zero.
We know that, for any positive integers a, b,
a + b = b + a .......................(1)
For any negative integers -a, -b
(-a) + (-b) = -a - b
= -(a + b)
= -(b + a) ...............(From (1))
= -b - a
= (-b) + (-a)
As, (-a) + (-b) = (-b) + (-a) for any negative integers -a, -b, the set of negative integers is a commutative group under the operation of addition.

a plane intersects only one nappe of a double-napped cone such that it is parallel to a generating line. which conic section is formed? responses parabola parabola hyperbola hyperbola circle circle ellipse
The equation of the parabola formed by the plane that is parallel to a generating line of a double napped cone is y = (A/B)x^2 + (6/B)x + (9/B + K/B).
The equation of a double napped cone is given by:
\(Ax^2 + By^2 + Cz^2 + 2Dxy + 2Exz + 2Fyz + 2Gx + 2Hy + 2Jz + K = 0\)
Where A, B, C, D, E, F, G, H, J and K are constants.
A plane that is parallel to a generating line of a double napped cone will intersect the cone at a single point, forming a parabola. The equation of a parabola can be written as:
y = ax^2 + bx + c
Where a, b, and c are constants.
We can find a, b and c by substituting the equation of the plane into the equation of the double napped cone.
For example, if the equation of the plane is x + y – z = 3 then we can substitute this into the equation of the double napped cone and solve for the coefficients a, b and c.
Substituting x + y – z = 3 into the equation of the double napped cone:
\(Ax^2 + By^2 + Cz^2 + 2Dxy + 2Exz + 2Fyz + 2Gx + 2Hy + 2Jz + K = 0\)
We get:
\(Ax^2 + B(x + 3)^2 + C(-x - 3)^2 + K = 0\)
Expanding, we get:
\(Ax^2 + Bx^2 + 6Bx + 9B + Cx^2 - 6Cx - 9C + K = 0\)
Grouping terms and solving for a, b and c, we get:
a = A/B
b = 6/B
c = 9/B + K/B
Therefore, the equation of the parabola formed by the plane that is parallel to a generating line of a double napped cone is y = (A/B)x^2 + (6/B)x + (9/B + K/B).

Find the angle between vector bold lower u equals 3 bold lower I plus start root 3 end root bold lower j and vector bold lower v equals negative 2 bold lower I minus 5 bold lower j to the nearest degree. A. 82° B. 38° C. 142° D. 98°
Answer:
C. 142°
Step-by-step explanation:
You want the angle between vectors u=3i+√3j and v=-2i-5j.
AngleThere are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:
u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest
You can find the angles of the vectors individually, and subtract those:
u = |u|∠α
v = |v|∠β
θ = α - β
When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:
\(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)
This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.
A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.
__
Additional comment
The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.
The dot-product relation will work with 3D vectors as well as 2D vectors.

Find the area of the parallelogram whose vertices are listed. (0,0),(3,6),(8,2),(11,8) The area of the parallelogram is square units.
The area of the parallelogram with vertices (0,0), (3,6), (8,2), and (11,8) is 0 square units.
To find the area of a parallelogram with given vertices, we can use the formula:
Area = |(x1y2 + x2y3 + x3y4 + x4y1) - (y1x2 + y2x3 + y3x4 + y4x1)| / 2
Given the vertices:
A = (0, 0)
B = (3, 6)
C = (8, 2)
D = (11, 8)
We can plug these coordinates into the formula to calculate the area:
Area = |(0*6 + 3*2 + 8*8 + 11*0) - (0*3 + 6*8 + 2*11 + 8*0)| / 2
Area = |(0 + 6 + 64 + 0) - (0 + 48 + 22 + 0)| / 2
Area = |70 - 70| / 2
Area = 0 / 2
Area = 0
Therefore, the area of the parallelogram with vertices (0,0), (3,6), (8,2), and (11,8) is 0 square units.

3. Note this example is using weeks instead of years to calculate the interest. Mr. Lindsey is
going to start a fund for the student who completes the highest amount of classwork
assignments during the rest of the quarter. He puts in $50 at the beginning of week one and
that money will draw interest at a given rate each week for 5 weeks. At the beginning of week 3
his honey business is going so well that he puts another 25 dollars in to draw interest for the
remaining 3 weeks. He puts another 30 at the beginning of week 4.
a) Write an expression to model this situation 50/5)
b) If I paid 4% interest over that period, how much money would the winner get?
Answer: Your welcome!
Step-by-step explanation:
a) The expression to model this situation is (50/5) + (25/3) + (30/2). This expression represents the amount of money Mr. Lindsey has in the fund at each week, starting at $50 for the first 5 weeks, then adding $25 for the remaining 3 weeks, and then adding $30 for the last 2 weeks.
b) If 4% interest is paid over the period, the winner of the fund will get a total of $70.14. This is calculated by multiplying the expression from part a) by 1.04 (1.04 = 1 + 4%) to get the total amount of money in the fund at the end of the period. In this case, (50/5) + (25/3) + (30/2) * 1.04 = 70.14.
