5. The independent variable is the period of time.

6. The dependent variable is the distance traveled by the car.

5. The independent variable is the period of time because it is the variable that is controlled or manipulated in this scenario. The car's speed remains constant at 60 miles per hour, and the time is the factor that can be changed or adjusted.

6. The dependent variable is the distance travelled by car because it is the variable that is influenced or affected by the independent variable. In this case, the distance traveled depends on the period of time for which the car maintains a constant speed of 60 miles per hour.

The longer the period of time, the greater the distance traveled, and vice versa. The relationship between the independent variable (time) and the dependent variable (distance) is determined by the constant rate of 60 miles per hour. As time increases, the car covers more distance, while as time decreases, the car covers less distance.

Therefore, the distance traveled is dependent on the period of time for which the car maintains its constant speed.

Explanation:

The type of test to be performed to test the hypothesis with the following data: Họ: H = 27, HA: μ< 27, X = 33, o= 2.5, and n= 77 is a left-tailed Z-test.

Hypothesis testing is a statistical technique that allows us to evaluate the validity of the hypothesis or assumptions regarding a population parameter. The hypothesis testing is based on several assumptions that must be met to test whether the null hypothesis is true or false.In this case, we will use the left-tailed Z-test since we have a sample size n > 30 and the population standard deviation is known as o= 2.5.Here are the steps for performing the left-tailed Z-test:

Step 1: State the null hypothesis and alternative hypothesis. H0: μ = 27 vs. Ha: μ < 27 (left-tailed test)

Step 2: Determine the level of significance (α). Assume α = 0.05

Step 3: Calculate the test statistic, which is given by: Z = (X - μ) / (o / √n)Where X is the sample mean, μ is the population mean, o is the population standard deviation, and n is the sample size.Z = (33 - 27) / (2.5 / √77)Z = 3.354

Step 4: Determine the p-value associated with the test statistic.Using a Z-distribution table or calculator, we find that the p-value is less than 0.001.

Step 5: Compare the p-value with the level of significance.Compare the p-value with α (0.05). Since the p-value is less than α, we reject the null hypothesis.Hence, the conclusion is that there is sufficient evidence to support the alternative hypothesis that the population mean is less than 27 at the 0.05 significance level.

The image of the given arbitrary quadratic polynomial is T([tex]ax^2 + bx + c[/tex]) = [tex](-2a + 2c)x^2 + (-2b + a)x + (-2a + b + 7c)[/tex].

To find the image of the arbitrary quadratic polynomial [tex]ax^2 + bx + c[/tex] under the linear transformation T, we can express the polynomial in terms of the standard basis of P3, which is {[tex]1, x, x^2[/tex]}.

The polynomial [tex]ax^2 + bx + c[/tex] can be written as a linear combination of the basis vectors:

[tex]ax^2 + bx + c = a(x^2) + b(x) + c(1)[/tex]

Since we know the values of T(1), T(x), and T([tex]x^2[/tex]), we can substitute them into the expression:

[tex]T(ax^2 + bx + c) = aT(x^2) + bT(x) + cT(1)[/tex]

Substituting the given values:

[tex]T(ax^2 + bx + c) = a(-2x^2 + x - 2) + b(-2x + 1) + c(2x^2 + 7)[/tex]

Simplifying the expression:[tex]T(ax^2 + bx + c) = (-2ax^2 + ax - 2a) + (-2bx + b) + (2cx^2 + 7c)[/tex]

Combining like terms:

[tex]T(ax^2 + bx + c) = (-2a + 2c)x^2 + (-2b + a)x + (-2a + b + 7c)[/tex]

Therefore, the image of the arbitrary quadratic polynomial [tex]ax^2 + bx + c[/tex] under the linear transformation T is [tex](-2a + 2c)x^2 + (-2b + a)x + (-2a + b + 7c)[/tex].

Step-by-step explanation:

a. The value of the swap to firm XYZ is -$23,225.33.

b. This would help to protect the firm against an increase in interest rates.

a. Calculation of the value of the swap to firm XYZ

The value of the swap to firm XYZ can be calculated using the following formula:

Value of Swap = Value of Fixed Leg - Value of Floating Leg

Where Value of Fixed Leg = VFL = (Coupon Rate * Principal * (1 - (1 + r)-n / r))

Value of Floating Leg = VFL = (Interest Rate * Principal * (1 - (1 + r)-n / r))

Where, Coupon Rate = 4% p.a. Principal = $20 million

Interest Rate = LIBOR + Spread, Spread = 0, therefore,

Interest Rate = 4.5% p.a.

Time to Maturity, n = 15 months

Remaining Time to Next Payment = 6 - 2 = 4 months

Therefore, the current six-month LIBOR rate is required to calculate the value of the swap as follows:

Current six-month LIBOR rate = 4.5% * (4/6) + x% * (2/6)x = ((Value of Swap/Principal + (1 - (1 + r)-n / r)) * r) / (1 - (1 + r)-n / r) = 0.0251%

Value of Fixed Leg = VFL = (0.04 * 20,000,000 * (1 - (1 + 0.05/2)-30 / (0.05/2))) = $1,328,816.76

Value of Floating Leg = VFL = (0.0451 * 20,000,000 * (1 - (1 + 0.05/2)-10 / (0.05/2))) = $1,352,042.09

Value of Swap = $1,328,816.76 - $1,352,042.09 = -$23,225.33

Therefore, the value of the swap to firm XYZ is -$23,225.33.

b. Suggest a reason why XYZ entered into the swap in the first place

Firm XYZ might have entered into the swap in the first place to mitigate the risk of a rise in interest rates in the future. By entering into a fixed-for-floating interest rate swap, the firm has fixed its borrowing cost for the duration of the swap at 4%, regardless of the future interest rate changes.

Therefore, this would help to protect the firm against an increase in interest rates.

Answer:

(√3·x - 1)(√3·x + 1)(4x - 3)

Step-by-step explanation:

Note that the last two coefficients are -4 and +3, and the associated factor is (4x - 3).

The first two terms are

12x^3 - 9x^2, which become 3x(4x^2 - 3x) through factoring and then 3x^2(4x - 3).  

Therefore, 12x3 – 9x2 – 4x + 3 can be rewritten as:

                   (4x - 3)(3x^2 - 1).  

It's possible to factor 3x^2 - 1, even though 3 is not a perfect square.  Write 3x^2 - 1 as (√3·x - 1)(√3·x + 1)    

Then 12x3 – 9x2 – 4x + 3 = (√3·x - 1)(√3·x + 1)(4x - 3)

Answer:

The value for partners savings bank at the end of 1 year is $12,362.70. The value for Selwyn's at the end of 1 year is $12,334.58. The future value obtained by investing in Partners Saving Bank is more as compared to Selwyn’s Saving Bank. Hence Joseph is recommended to choose Partners Saving Bank.

Step-by-step explanation:

The value of the interest rate and the compounding applied, gives the

value in the account after one year.

Reasons:

The amount Joseph receives as gift, A₀ = $12,000

Amount interest from Partner's Savings Bank, r = 3% compounded semiannually

Interest rate offered by Selwyn's, r = 2.75% compounded continuously

Required:

The value of the two account at the end of one year.

Solution:

[tex]A_t = A_0 \cdot \left(1 + \dfrac{r}{2} \right)^{2 \times t}[/tex]

The amount at the end of one year (t = 1) in Partner's Savings Bank is therefore;

[tex]A_t = 12,000 \times \left(1 + \dfrac{0.03}{2} \right)^{2 \times 1} = 12,362.7[/tex]

The value of an account at Selwyn's is therefore;

The interest rate compounded continuously is presented as follows;

[tex]A(t) = \mathbf{A_0 \cdot e^{r \cdot t}}[/tex]

A₀ = The original amount invested = $12,000

Which gives;

[tex]A(t) = 12,000 \times e^{0.0275 \times 1} \approx \mathbf{12,334.58}[/tex]

Step 1: Write down the given probabilities. Using the standard normal table, we find the following probabilities: P(-1.721  = 0.0426 (rounding off to four decimal places)

Step 2: Find the value of k for (a)We need to find k such that P(-1.721  = 0.0426.From the table, we get the area between the mean (0) and z = -1.72 as 0.0426. Therefore,-k = -1.72k = 1.72Therefore, k = 1.72

(a) The improper integral ∫[0,∞] [tex](xe^(-2x)dx)[/tex] converges.

(b) To evaluate the integral ∫[0,1] [tex](4\sqrt{1-x^2}dx)[/tex], we can use the trigonometric substitution x = sin(θ).

(c) The general solution to the given differential equation is y = ln|x + 2| - ln|x - 1| + C.

(a) To determine if the improper integral ∫[0,∞] [tex](xe^{-2x}dx)[/tex] converges or diverges, we can use the limit comparison test.

Let's consider the function f(x) = x and the function g(x) = [tex]e^{-2x}[/tex].

Since both f(x) and g(x) are positive and continuous on the interval [0,∞], we can compare the integrals of f(x) and g(x) to determine the convergence or divergence of the given integral.

We have ∫[0,∞] (x dx) and ∫[0,∞] [tex](e^(-2x) dx)[/tex].

The integral of f(x) is ∫[0,∞] (x dx) = [[tex]x^2/2[/tex]] evaluated from 0 to ∞, which gives us [∞[tex]^2/2[/tex]] - [[tex]0^2/2[/tex]] = ∞.

The integral of g(x) is ∫[0,∞] [tex](e^{-2x} dx)[/tex] = [tex][-e^{-2x}/2][/tex] evaluated from 0 to ∞, which gives us [[tex]-e^{-2\infty}/2[/tex]] - [[tex]-e^0/2[/tex]] = [0/2] - [-1/2] = 1/2.

Since the integral of g(x) is finite and positive, while the integral of f(x) is infinite, we can conclude that the given integral ∫[0,∞] ([tex]xe^{-2x}dx[/tex]) converges.

(b) To evaluate the integral ∫[0,1] (4√([tex]1-x^2[/tex])dx), we can make the trigonometric substitution x = sin(θ).

When x = 0, we have sin(θ) = 0, so θ = 0.

When x = 1, we have sin(θ) = 1, so θ = π/2.

Differentiating x = sin(θ) with respect to θ, we get dx = cos(θ) dθ.

Now, substituting x = sin(θ) and dx = cos(θ) dθ in the integral, we have:

∫[0,1] (4√([tex]1-x^2[/tex])dx) = ∫[0,π/2] (4√(1-[tex]sin^2[/tex](θ)))cos(θ) dθ.

Simplifying the integrand, we have √(1-[tex]sin^2[/tex](θ)) = cos(θ).

Therefore, the integral becomes:

∫[0,π/2] (4[tex]cos^2[/tex](θ)cos(θ)) dθ = ∫[0,π/2] (4[tex]cos^3[/tex](θ)) dθ.

Now, we can integrate the function 4[tex]cos^3[/tex](θ) using standard integration techniques:

∫[0,π/2] (4[tex]cos^3[/tex](θ)) dθ = [sin(θ) + (3/4)sin(3θ)] evaluated from 0 to π/2.

Plugging in the values, we get:

[sin(π/2) + (3/4)sin(3(π/2))] - [sin(0) + (3/4)sin(3(0))] = [1 + (3/4)(-1)] - [0 + 0] = 1 - 3/4 = 1/4.

Therefore, the value of the integral ∫[0,1] (4√([tex]1-x^2[/tex])dx) is 1/4.

(c) To find the general solution to the differential equation ([tex]x^2 + x - 2[/tex])(dy/dx) = 3, for x ≠ -2, 1, we need to separate the variables and integrate both sides.

(dy/dx) = 3 / ([tex]x^2 + x - 2[/tex]).

∫(dy/dx) dx = ∫(3 / ([tex]x^2 + x - 2[/tex])) dx.

Integrating the left side gives us [tex]y + C_1[/tex], where [tex]C_1[/tex] is the constant of integration.

To evaluate the integral on the right side, we can factor the denominator:

∫(3 / ([tex]x^2 + x - 2[/tex])) dx = ∫(3 / ((x + 2)(x - 1))) dx.

Using partial fractions, we can express the integrand as:

3 / ((x + 2)(x - 1)) = A / (x + 2) + B / (x - 1).

Multiplying both sides by (x + 2)(x - 1), we have:

3 = A(x - 1) + B(x + 2).

Expanding and equating coefficients, we get:

0x + 3 = (A + B)x + (-A + 2B).

Equating the coefficients of like terms, we have:

A + B = 0,

- A + 2B = 3.

Solving this system of equations, we find A = -3 and B = 3.

3 / ((x + 2)(x - 1)) = (-3 / (x + 2)) + (3 / (x - 1)).

∫(3 / ([tex]x^2 + x - 2[/tex])) dx = -3∫(1 / (x + 2)) dx + 3∫(1 / (x - 1)) dx.

-3ln|x + 2| + 3ln|x - 1| + C2,

where C2 is another constant of integration.

Therefore, the general solution to the differential equation is:

y = -3ln|x + 2| + 3ln|x - 1| + C,

where C = C1 + C2 is the combined constant of integration.
