Use the formula t = 1.06p to find t when p is 8.5.

The speed of the car is 13/16 mile per minute.

To find the speed of the car per minute, we need to divide the distance traveled by the time taken.

Given that the car traveled 1/8 mile in 2/13 minutes, we can calculate the speed as follows:

Speed = Distance / Time

Speed = (1/8 mile) / (2/13 min)

To divide by a fraction, we can multiply by the reciprocal:

Speed = (1/8 mile) * (13/2 min)

Simplifying the expression:

Speed = (1 * 13) / (8 * 2) mile/min

Speed = 13/16 mile/min

Therefore, the speed of the car is 13/16 mile per minute.

To determine whether a function is even or odd, you can follow these steps:

1. Understand the definitions:
  - An even function is symmetric with respect to the y-axis. This means that if you reflect the graph of an even function across the y-axis, it remains unchanged.
  - An odd function is symmetric with respect to the origin. This means that if you rotate the graph of an odd function by 180 degrees about the origin, it remains unchanged.

2. Examine the function's algebraic form:
  - An even function is characterized by f(-x) = f(x) for all x in the domain. In other words, substituting -x into the function should yield the same result as substituting x.
  - An odd function is characterized by f(-x) = -f(x) for all x in the domain. In other words, substituting -x into the function should yield the negative of the result obtained by substituting x.

3. Analyze the function graphically:
  - Plot the function on a graph and determine if it exhibits symmetry.
  - For an even function, you should observe that the graph is symmetric with respect to the y-axis. It should look the same on both sides of the y-axis.
  - For an odd function, you should observe that the graph is symmetric with respect to the origin. It should look the same when rotated by 180 degrees around the origin.

4. Example:
  - Let's consider the function f(x) = x^2.
  - Substituting -x into the function, we have f(-x) = (-x)^2 = x^2, which is the same as f(x).
  - Therefore, f(x) = x^2 is an even function.
  - Graphically, if we plot the function, we will see that it is symmetric with respect to the y-axis.

In summary, determining whether a function is even or odd involves understanding the definitions, analyzing the algebraic form, and examining the graphical representation of the function. By following these steps, you can determine the symmetry properties of a given function.

The distance between City A and City C, when an automobile driven at speed of 65 mph takes 1.8 hours to drive from City A to City B and takes 1.2hours to drive from City B to City C, is approximately 287.87 miles.

Given that the bearing from City A to City B is N 56° E and the bearing from City B to City C is S 34° E. Also, the time taken by the automobile to drive from A to B and from B to C is 1.8 hours and 1.2 hours, respectively.

The standard form of a quadratic equation is f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola. Therefore, comparing f(x) with the standard form, we get the vertex form of the equation as: f(x) = 2(x + 3)² - 4 = 2(x - (-3))² - 4. So, the vertex of the parabola is (-3, -4).

The axis of symmetry is the line that passes through the vertex of the parabola and is parallel to the y-axis. Hence, the axis of symmetry is x = -3.

To find a second point on the parabola whose y-coordinate is the same as the given point, we can use the reflection property of the vertex. Since the parabola is symmetric about the axis of symmetry, the y-coordinate of the point that is the same distance from the axis of symmetry as (-2, -2) will be the same as the y-coordinate of (-2, -2).

The distance between x-coordinate of (-2, -2) and the axis of symmetry x = -3 is 1 unit. Therefore, the x-coordinate of the required point will be 1 unit to the right of the axis of symmetry. Since the parabola is symmetric about the axis of symmetry, the x-coordinate of the point that is 1 unit to the right of the axis of symmetry will be the same as the x-coordinate of the point that is 1 unit to the left of the axis of symmetry.

The x-coordinate of the point that is 1 unit to the left of the axis of symmetry is -3 - 1 = -4. Hence, the x-coordinate of the required point is -4 + 1 = -3. The y-coordinate of the required point is the same as the y-coordinate of (-2, -2). Hence, the required point is (-3, -2).

Therefore, the equation of the axis of symmetry is x = -3 and the second point on the parabola whose y-coordinate is the same as the given point (-2, -2) is (-3, -2).

The evaluated integral is \(\frac{1}{4}e^4 - \frac{3}{4}\).Since the lower limit is greater than the upper limit, we need to reverse the order of integration.

To evaluate the given integral \(\int_{1}^{0} \int_{2}^{2y} e^{x^2} \, dx \, dy\), we will reverse the order of integration.

First, let's analyze the limits of integration. The inner integral is with respect to \(x\) and it goes from \(2\) to \(2y\). The outer integral is with respect to \(y\) and it goes from \(1\) to \(0\). However, since the lower limit is greater than the upper limit, we need to reverse the order of integration.

Let's start by writing the integral with the reversed order of integration:

\(\int_{0}^{1} \int_{2}^{2y} e^{x^2} \, dx \, dy\)

Now, we will evaluate the integral by integrating with respect to \(x\) first and then with respect to \(y\).

Integrating \(e^{x^2}\) with respect to \(x\) gives us \(e^{x^2}\).

Now, we will evaluate the inner integral:

\(\int_{2}^{2y} e^{x^2} \, dx = \left[e^{x^2}\right]_{2}^{2y} = e^{(2y)^2} - e^{2^2} = e^{4y^2} - e^4\)

Next, we integrate the resulting expression with respect to \(y\):

\(\int_{0}^{1} (e^{4y^2} - e^4) \, dy\)

Integrating \(e^{4y^2} - e^4\) with respect to \(y\) gives us \(\frac{1}{4}e^{4y^2} - e^4y\).

Now, we evaluate the outer integral:

\(\left[\frac{1}{4}e^{4y^2} - e^4y\right]_{0}^{1}\)

Plugging in the limits of integration, we get:

\(\frac{1}{4}e^{4(1)^2} - e^4(1) - \left(\frac{1}{4}e^{4(0)^2} - e^4(0)\right)\)

Simplifying further, we have:

\(\frac{1}{4}e^4 - e^4 - \left(\frac{1}{4} - 0\right)\)

Which simplifies to:

\(\frac{1}{4}e^4 - \frac{3}{4}\)

Therefore, the evaluated integral is \(\frac{1}{4}e^4 - \frac{3}{4}\).

Given a mean and standard deviation of 3,500 and 2,000 cfs, respectively, the 2-, 10-, and 100-year peak floods for a normal distribution can be found as follows:

Formula used in finding the peak flood is as follows:

Q_T= Q_m + K_T

σ

Where Q_T is the flow for a given period,

Q_m is the mean flow, K_T is the coefficient of skewness, and σ is the standard deviation of the flows.

For a normal distribution, K_T= frac{\text{duration of period in years}-1}{2}\times\frac{\text{duration of period in years}+1}{2}

Substitute the mean and standard deviation to the formula above:

When the period of interest is 2 years, the coefficient of skewness is calculated below:

[{{K}_{T}}=\frac{\text{(2-1)(2+1)}}{2}=1\]

Also, K_{T} is 1 for the 10-year and 100-year flood.

When these values are computed, we get the following values:

Q_{2}=3500+1(2000)=5500 \text{ cfs}

Q_{10}=3500+1(2000)=5500 \text{ cfs}

In the first scenario where sin(α) = 0 and cos(α) < 0, we have cos(α) = -1. In the second scenario where sin(α) = 5/13 and α is in quadrant ∥, we have cos(α) = -12/13.

In the first scenario, we are given that sin(α) = 0 and cos(α) < 0. Since sin(α) = 0, it means that the angle α must be a multiple of π (180 degrees). In other words, α is either 0 or an integer multiple of π. However, since cos(α) < 0, it indicates that α lies in the second or third quadrant, where cosine values are negative.

If α = 0, then cos(α) = cos(0) = 1, which contradicts the given condition that cos(α) < 0. Therefore, α must be a non-zero angle in the second or third quadrant.

In the second and third quadrants, cosine is negative. Since sin(α) = 0, we know that α is on the x-axis, where cosine takes its maximum or minimum negative value of -1. Therefore, in this scenario, cos(α) = -1.

In the second scenario, we are given sin(α) = 5/13 and α is in quadrant ∥ (presumably the second quadrant since sine is positive in the second quadrant). To find cos(α), we can use the Pythagorean identity: sin²(α) + cos²(α) = 1.

Since we know sin(α) = 5/13, we can substitute the value and solve for cos²(α): (5/13)² + cos²(α) = 1 25/169 + cos²(α) = 1 cos²(α) = 1 - 25/169 cos²(α) = 144/169

Since α is in the second quadrant where cosine is negative, cos(α) must be negative. Taking the negative square root of cos²(α), we find: cos(α) = -12/13.

The perimeter of a rectangle is calculated by adding up the lengths of all four sides. In this case, we are given that the perimeter is 13 1/2 cm.

The formula for the perimeter of a rectangle is:

Perimeter = 2(length + width)

Substituting the given values:

13 1/2 = 2(4 1/4 + w)

To simplify the equation, we convert all mixed numbers to improper fractions:

Perimeter = 2(17/4 + w)

Next, we distribute the 2:

13 1/2 = 34/4 + 2w

Now, let's simplify the equation by finding a common denominator:

13 1/2 = 8 1/2 + 2w

We subtract 8 1/2 from both sides to isolate 2w:

5 = 2w

The solution to the given Bernoulli's differential equation xy - dy/dx = y³ e⁻ˣ^² is  y = -1/(3Ei(-x^2) + C).

To solve the given Bernoulli's differential equation, we can use a substitution. Let's substitute y = u^(1-n) where n is not equal to 0 and 1.

Here's how we solve it step-by-step:

1. Start by differentiating both sides of the equation with respect to x:
  d/dx (xy - dy/dx) = d/dx (y^3 e^(-x^2))

2. Simplify the left side using the product rule:
  y + x(dy/dx) - dy/dx = 3y^2 e^(-x^2) * d/dx (e^(-x^2))

3. Differentiate the right side using the chain rule:
  y + x(dy/dx) - dy/dx = 3y^2 e^(-x^2) * (-2x)

4. Rearrange the equation to isolate dy/dx terms on one side:
  x(dy/dx) - dy/dx = 3y^2 e^(-x^2) * (-2x) - y

5. Multiply both sides of the equation by dx:
  xdy - ydx = -2x * 3y^2 e^(-x^2) dx - ydx

6. Simplify the equation by canceling out the common terms:
  xdy = -6xy^2 e^(-x^2) dx

7. Divide both sides of the equation by x * y^2 to separate variables:
  (1/y^2) dy = -6e^(-x^2) dx/x

8. Integrate both sides of the equation:
  ∫(1/y^2) dy = ∫-6e^(-x^2) dx/x

9. The left side of the equation can be integrated as follows:
  ∫(1/y^2) dy = -1/y

10. The right side of the equation requires a substitution. Let's substitute u = -x^2, then du/dx = -2x:
  ∫-6e^(-x^2) dx/x = -6 ∫e^u du/-2u
                     = 3 ∫e^u du/u

11. The integral on the right side is a special function called the exponential integral, Ei(u). So we have:
  -1/y = 3Ei(u) + C

12. Substitute back u = -x^2:
  -1/y = 3Ei(-x^2) + C

13. Rearrange the equation to solve for y:
  y = -1/(3Ei(-x^2) + C)

That's the solution to the given Bernoulli's differential equation. Remember to consider any initial conditions or constraints to determine the value of the constant C.

Formula for payment per period in amortized loan: PV = Pmt × [1 – (1 + r/100)-n]/(r/100)

Where, PV = Present Value

Pmt = Payment per period

r = Annual interest rate

n = Number of periods

On substituting the values, we get: $14,000 = Pmt × [1 – (1 + 7/100)-6]/(7/100)

Pmt = $2,766.52

Approximate answer: $2,766.522.

Calculation of interest and principal repayment for the first payment: Principal repayment for the first payment: Out of the total loan of $14,000, the first payment will be made after a year.

Hence, the present value of the loan will be equal to the future value of the principal repayment. The interest rate for one year is 7%, and hence future value of the principal is:$14,000 × (1 + 7/100) = $14,980

Interest payment for the first payment: The total payment for the first year is $2,766.52. Out of this amount, the principal repayment is $14,980 and the remaining amount is interest payable. Hence, interest payable for the first year = Total payment - Principal repayment = $2,766.52 - $14,980 = -$12,213.48 (negative value)

Therefore, the interest payment and the principal repayment for the first payment are:- Interest: -$12,213.48- Principal repayment: $14,980

Given that ℓ₁ and ℓ₂ are parallel lines, and ℓ₃ is a third line, distinct from ℓ₁.

Let's assume that ℓ₃ intersects ℓ₁. Let the intersection point be A,

Then, we will have the following: AB||CD, and ℓ₁⊥AB, ℓ₂⊥CD (As they are parallel lines).

Therefore, ℓ₂ is perpendicular to CD, and AB is perpendicular to ℓ₁. Also, AB is perpendicular to CD (because they intersect perpendicularly at A).

Therefore, CD is perpendicular to both ℓ₁ and ℓ₂. Hence, ℓ₂ intersects ℓ₃.

Thus, it is proved that if ℓ₃ intersects ℓ₁ then it also must intersect ℓ₂.

By differentiating the polynomial function, finding the critical points, and evaluating the function at these points and the endpoints, we can determine the maximum and minimum values of the polynomial function.

To find the maximum and minimum of a polynomial function, follow these steps:

1. Differentiate the polynomial function to find its derivative.

2. Set the derivative equal to zero and solve for the critical points.

3. Evaluate the polynomial at the critical points and the endpoints of the interval to determine the maximum and minimum values.

To find the maximum and minimum of a polynomial function, we start by differentiating the function. The derivative represents the rate of change of the function and helps us identify the critical points where the function may reach its extreme values.

Once we have the derivative, we set it equal to zero to find the critical points. Solving this equation gives us the x-values where the function may have a maximum or minimum. Additionally, we need to consider the endpoints of the interval over which we are analyzing the function.

After obtaining the critical points and the endpoints, we evaluate the polynomial at these values to determine the corresponding y-values. The highest y-value corresponds to the maximum of the function, while the lowest y-value corresponds to the minimum.

By differentiating the polynomial function, finding the critical points, and evaluating the function at these points and the endpoints, we can determine the maximum and minimum values of the polynomial function.

|f(x)| > |g(x)|, For the first part (i), both f(x) and g(x) are greater than 0. So, f(x) > g(x). For the second part, f(x) < g(x) which contradicts the equation, and the solutions to the equation |2−5x|=5|x+1| are x = -3/5 and x = -7/5.

Assume, for the sake of contradiction, that f(x) is not equal to g(x) and f(x) is not equal to -g(x). Let's break the proof down into two parts:

(i) f(x) > 0(ii) f(x) < 0. For the first part (i), If f(x) > 0, then g(x) > 0 (as |g(x)| = |f(x)|). Since both f(x) and g(x) are greater than 0, it means that f(x) is greater than g(x). Thus, f(x) > g(x).

For the second part (ii),If f(x) < 0, then g(x) < 0 (as |g(x)| = |f(x)|). Since both f(x) and g(x) are less than 0, it means that f(x) is less than g(x). Thus, f(x) < g(x). But then |f(x)| < |g(x)|, which contradicts the given statement that |f(x)| = |g(x)|.

Now, let's use this result to solve the equation |2−5x|=5|x+1|. We can write this as 2 - 5x = 5x + 5  or  2 - 5x = -5x - 5. Expanding the absolute value signs, we get:

2 - 5x = 5x + 5  or  2 - 5x = -5x - 5

Solving the first equation, we get:

x = -3/5

Solving the second equation, we get:

The parabola opens upward and the vertex represents the minimum value, the range of the function is all real numbers greater than or equal to 12.

The range of a quadratic function can be determined by finding the vertex and the leading coefficient of the quadratic equation.

In the given quadratic function, \[ f(x)=2 x^{2}+16 x+28 \], the leading coefficient is 2.

Since the leading coefficient is positive, the parabola opens upward. This means that the vertex represents the minimum value of the function, and the range will extend from the minimum value to positive infinity.

To find the vertex, we can use the formula: \[ x = -\frac{b}{2a} \]

In this case, a = 2 and b = 16. Plugging these values into the formula, we get:

\[ x = -\frac{16}{2(2)} = -4 \]

To find the corresponding y-value or the minimum value of the function, we substitute this x-value back into the equation:

\[ f(-4) = 2(-4)^2 + 16(-4) + 28 = 12 \]

So, the vertex is (-4, 12).

Since the parabola opens upward and the vertex represents the minimum value, the range of the function is all real numbers greater than or equal to 12.

Using interval notation, we can write the range as \[ [12, \infty) \]. This means that the range includes all values from 12 to positive infinity, including 12 itself.

The total equivalent units for conversion costs are 58,635 tons (rounded to the nearest whole unit).

To calculate the total equivalent units for conversion costs, we need to consider the units that were in beginning work in process inventory and the units completed during the period.

Units in beginning work in process inventory:

The beginning work in process inventory was 3,668 tons, and it was 80% complete. So the equivalent units for conversion costs in the beginning inventory are 3,668 tons * 80% = 2,934.4 tons (rounded to the nearest whole unit).

Units completed during October:

During October, 52,400 tons were completed. Since these units were completed, they are considered 100% complete for conversion costs. Therefore, the equivalent units for conversion costs for the completed units are 52,400 tons.

Units in ending work in process inventory:

The ending work in process inventory was 4,716 tons, and it was 70% complete. So the equivalent units for conversion costs in the ending inventory are 4,716 tons * 70% = 3,301.2 tons (rounded to the nearest whole unit).

Now, we can calculate the total equivalent units for conversion costs by summing up the equivalent units from the three categories:

Total equivalent units for conversion costs = Equivalent units in beginning inventory + Equivalent units for completed units + Equivalent units in ending inventory

= 2,934 + 52,400 + 3,301

= 58,635 tons (rounded to the nearest whole unit).

Therefore, the total equivalent units for conversion costs are 58,635 tons (rounded to the nearest whole unit).
