Give a specific reason why the following set R does not define an equivalence relation on the set {1, 2, 3, 4}.R = {(1, 1), (2, 2), (3, 3), (4, 4), (2, 3), (3, 2), (2, 4), (4, 2)}
The following set R does not define an equivalence relation, as it is not satisfying the transitive property.
Equivalence relation: In mathematics equivalence relation is a kind of binary relation which is reflexive, symmetric, and transitive.
The given set is {1, 2, 3, 4} which is forming a relation R where R = {(1, 1), (2, 2), (3, 3), (4, 4), (2, 3), (3, 2), (2, 4), (4, 2)}
This relation is following reflexive property as (1, 1), (2, 2), (3, 3), (4, 4) all are present in the relation
This relation is following symmetric property as (2, 3), (3, 2), (2, 4), (4, 2) all are there in the relation
But the relation is not following transitive property as (2,3) ,(4,2) are there but (4,3) is not there in the relation . So it is not transitive.
Therefore the given relation is not an equivalence relation because it is not transitive .

find the volume of the solid formed by revolving the region bounded by the graphs of y = 4x - x^2 and f(x) = x^2 from [0,2] about the... a) x-axis.
Answer:
\(v = \frac{32\pi}{3}\)
or
\(v=33.52\)
Step-by-step explanation:
Given
\(f(x) = 4x - x^2\)
\(g(x) = x^2\)
\([a,b] = [0,2]\)
Required
The volume of the solid formed
Rotating about the x-axis.
Using the washer method to calculate the volume, we have:
\(\int dv = \int\limit^b_a \pi(f(x)^2 - g(x)^2) dx\)
Integrate
\(v = \int\limit^b_a \pi(f(x)^2 - g(x)^2)\ dx\)
\(v = \pi \int\limit^b_a (f(x)^2 - g(x)^2)\ dx\)
Substitute values for a, b, f(x) and g(x)
\(v = \pi \int\limit^2_0 ((4x - x^2)^2 - (x^2)^2)\ dx\)
Evaluate the exponents
\(v = \pi \int\limit^2_0 (16x^2 - 4x^3 - 4x^3 + x^4 - x^4)\ dx\)
Simplify like terms
\(v = \pi \int\limit^2_0 (16x^2 - 8x^3 )\ dx\)
Factor out 8
\(v = 8\pi \int\limit^2_0 (2x^2 - x^3 )\ dx\)
Integrate
\(v = 8\pi [ \frac{2x^{2+1}}{2+1} - \frac{x^{3+1}}{3+1} ]|\limit^2_0\)
\(v = 8\pi [ \frac{2x^{3}}{3} - \frac{x^{4}}{4} ]|\limit^2_0\)
Substitute 2 and 0 for x, respectively
\(v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ \frac{2*0^{3}}{3} - \frac{0^{4}}{4} ])\)
\(v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ 0 - 0])\)
\(v = 8\pi [ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ]\)
\(v = 8\pi [ \frac{16}{3} - \frac{16}{4} ]\)
Take LCM
\(v = 8\pi [ \frac{16*4- 16 * 3}{12}]\)
\(v = 8\pi [ \frac{64- 48}{12}]\)
\(v = 8\pi * \frac{16}{12}\)
Simplify
\(v = 8\pi * \frac{4}{3}\)
\(v = \frac{32\pi}{3}\)
or
\(v=\frac{32}{3} * \frac{22}{7}\)
\(v=\frac{32*22}{3*7}\)
\(v=\frac{704}{21}\)

Suppose you work for a company that manufactures electronics. The development analysts estimate that 5% of their flagship product will fail within 2 years of the purchase date, with a replacement cost of $ 1200. A newly hired associate at the company proposes to charge $ 50 for a 2-year warranty. 1. Compute the expected value of this proposal. Let X be the amount profited or lost (by the company) on the warranties and P(X) is the probability. 2. Interpret the expected value in complete sentences.
The expected value of the proposal is -$10. This means that, on average, the company can expect to lose $10 per warranty sold.
Interpretation of the expected value:
The expected value of -$10 indicates that, on average, for every 2-year warranty sold, the company can expect to lose $10. This means that the proposal is not a profitable venture for the company. The replacement costs of the 5% of failed products are higher than the revenue generated by selling the warranties and cannot cover the potential losses.
To compute the expected value of the proposal, we need to calculate the amount profited or lost (X) by the company on the warranties and the probability (P(X)) of each outcome.
Now, we have,
The product doesn't fail within 2 years, and the company earns $50 from the warranty.
The product fails within 2 years, and the company incurs a replacement cost of $1200 but keeps the $50 warranty fee.
The probability of the product not failing within 2 years is 1 - 0.05 = 0.95,
and the probability of the product failing within 2 years is 0.05.
Now, we have to find the expected value (E(X)):
\(E(X) = P(X_1) * X_1 + P(X_2) * X_2\)
Where:
\(P(X_1)\) = Probability of the product not failing within 2 years = 0.95
\(X_1\) = Amount profited when the product doesn't fail within 2 years = $50
\(P(X_2)\) = Probability of the product failing within 2 years = 0.05
\(X_2\) = Amount lost when the product fails within 2 years = -$1150 (Replacement cost of $1200 - $50 warranty fee)
E(X) = 0.95 * $50 + 0.05 * (-$1150)
E(X) = $47.50 - $57.50
E(X) = -$10
The expected value of the proposal is -$10. This means that, on average, the company can expect to lose $10 per warranty sold.
Interpretation of the expected value:
The expected value of -$10 indicates that, on average, for every 2-year warranty sold, the company can expect to lose $10. This means that the proposal is not a profitable venture for the company. The replacement costs of the 5% of failed products are higher than the revenue generated by selling the warranties and cannot cover the potential losses. As a result, the company might want to reconsider the pricing of the warranty or look for other ways to reduce the potential costs associated with the product failures.

Answer:
d 9 years, 11 months
Step-by-step explanation:
Rachel deposited $5,960.32 into a savings account with an interest rate of 4.2% compounded twice a year.
P = $5,960.32
Rate = 4.2%
Number of years = x
Final amount=$9000
Number of times compounded= x/2
A= p(1+r/n)^(nt)
9000= 5960.32(1+(0.042*2)/x)^(x/2 *x)
9000= 5960.32(1+0.084/x)^x²/2
2(9000/5960.32)=(1+0.084/x)^x²

(F) Four complex roots
What is a polynomial?A polynomial is a mathematical expression that consists of variables and coefficients joined together by addition, subtraction and multiplication, with the exponents of the variables consisting of positive integer values.
Part A) The polynomial in standard form is; 2·x⁴ + 3·x³ + 9·x² - 12·x + 6
Part B) The degree of the polynomial is 4, as the highest power of the polynomial is 4
Part C) The use of the Rule of Signs, to determine the options for the number of positive zeroes, negative zeroes and complex zeroes, can be presented as follows;
Positive zeroes options; The number of time the signs coefficients of the expression; 2·x⁴ + 3·x³ + 9·x² - 12·x + 6, changes are two as follows;
+6 to -12, and from -12 to +9, therefore, the number of possible positive zeroes are 2 or 0, positive zeroes
The negative zeroes options; The negative zeroes options can be found by changing the sign of all the coefficients as follows; -2·x⁴ - 3·x³ - 9·x² + 12·x - 6, therefore, the number of times the sign of the coefficients change are again from -6 to +12, and from +12 to -9, which is 2 times, therefore;
The possible number of negative zeros are 2 or 0, negative zeroes
Whereby there are possibly 0 negative zeros and 0 positive zeroes, the possible number of complex zeroes are 4
Whereby there are 2 negative zeros and 0 positive zeroes, the possible number of complex zeroes are 2 complex zeroes
Whereby there are possibly 0 negative zeros and 2 positive zeroes, the possible number of complex zeroes are 2 complex zeroes
Part D) The rational roots theorem indicates that for a polynomial the rational roots are in the form p/q, where p is a factor of the constant term, and q is a factor of the leading coefficient.
The constant term is 6, and the leading coefficient is 2. The factors of 6 are ±1, ±2, ±3, and ±6 and the factors of 2 are; ±1, ±2 therefore;
p/q = ±1/1, ±2/1, ±3/1, ±6/1, ±1/2, ±2/2, ±3/2, ±6/2, which can be summarized as; ±1/2, ±1, ±3/2, ±2, ±3, ±6
Part E) Please find attached a screenshot of the graph of the polynomial created with MS Excel

write down the integrals you would need to solve to determine the average momentum for the particle in problem 1.
The average momentum of the particle is 5.
To find the average momentum for the particle in problem 1, we need to calculate the following integrals:
1. The integral of the momentum with respect to time, which is the total momentum of the particle over the given time interval:
∫P(t)dt
2. The integral of time with respect to time, which is the total time of the particle over the given time interval:
∫t dt
Then, we can find the average momentum by dividing the total momentum by the total time:
Pavg = ∫P(t)dt/∫t dt
For example, if the momentum of the particle is given by P(t) = 5t + 2, then we can calculate the average momentum by first calculating the integrals of P(t) and t over the given time interval [0,5]:
∫P(t)dt = 5t²/2 + 2t, evaluated from 0 to 5 = 62.5
∫t dt = t²/2, evaluated from 0 to 5 = 12.5
Therefore, the average momentum of the particle is Pavg = 62.5/12.5 = 5.
The average momentum of the particle is 5.
