I don't know what the question is but I'm pretty sure the answer is 5.5.

X = 5.5 or the price of each cake is 5.5$

Answer: (2,0), (2,1), and (6,1)

Step-by-step explanation: I just used the desmos graphing calculator to find the answer to your problem. I don't know any formulas to solve it so I just rotated the points by hand. I also made sure they were still equidistant from the point (2,-1) because if their distances from other points changed during the rotation, then the triangle would not be equal to the first triangle and the image would've been distorted.

I hope this helps! Have a nice day.

The most helpful substitution for evaluating the given integral is option A: x = 14sinθ.

:

To evaluate the integral ∫dx/(196 - x^2)^2, we can use the trigonometric substitution x = 14sinθ. This substitution is effective because it allows us to express (196 - x^2) and dx in terms of trigonometric functions.

To find dx, we differentiate both sides of the substitution x = 14sinθ with respect to θ:

dx/dθ = 14cosθ

Rearranging the equation, we can solve for dx:

dx = 14cosθ dθ

Now, substitute x = 14sinθ and dx = 14cosθ dθ into the original integral:

∫dx/(196 - x^2)^2 = ∫(14cosθ)/(196 - (14sinθ)^2)^2 * 14cosθ dθ

Simplifying the expression under the square root and combining the constants, we have:

= ∫196cosθ/(196 - 196sin^2θ)^2 * 14cosθ dθ

= ∫196cosθ/(196 - 196sin^2θ)^2 * 14cosθ dθ

= 196 * 14 ∫cos^2θ/(196 - 196sin^2θ)^2 dθ

Now, we can proceed with integrating the new expression using trigonometric identities or other integration techniques.

The series converges absolutely since there exist a p-series with p=6, and since p>1, therefore series converges absolutely.

To determine whether the series ∑(n=1 to infinity) (−1)^n(1 + 1/n^6) converges absolutely, conditionally, or not at all, we need to analyze the terms of the series.

First, let's check for absolute convergence. To do this, we take the absolute value of the terms in the series:
| (−1)^n(1 + 1/n^6) | = | (−1)^n | * | 1 + 1/n^6 |

Since | (−1)^n | = 1, this simplifies to:
| 1 + 1/n^6 |

Now, we need to test this new series for convergence. We can use the comparison test, by comparing it to the series ∑(n=1 to infinity) (1/n^6), which is a p-series with p = 6.

Since 6 > 1, the p-series converges, and because 1 + 1/n^6 > 1/n^6 for all n, the original series also converges absolutely.

Therefore, the series ∑(n=1 to infinity) (−1)^n(1 + 1/n^6) converges absolutely.

The values after bubble sort is called on an input array of length n has the complexity O(n²)

Bubble sort is a simple sorting algorithm that is commonly taught in high school. It works by repeatedly swapping adjacent elements that are in the wrong order until the entire array is sorted.

To better understand the values of the array after bubble sort, let's take an example. Suppose we have the following input array of length 5:

[4, 2, 8, 5, 1]

After the first pass of bubble sort, the largest element (8) is at the end of the array:

[2, 4, 5, 1, 8]

After the second pass, the second largest element (5) is at the second-to-last position:

[2, 4, 1, 5, 8]

After the third pass, the third largest element (4) is at the third-to-last position:

[2, 1, 4, 5, 8]

After the fourth and final pass, the array is fully sorted:

[1, 2, 4, 5, 8]

As you can see, bubble sort swaps adjacent elements until the largest element "bubbles up" to the end of the array, and the process repeats until the entire array is sorted in ascending order.

It's worth noting that bubble sort has a worst-case time complexity of O(n²), meaning that the number of comparisons and swaps required grows quadratically with the size of the input array.

Step-by-step explanation:

Measuring the two new angles included between the new ray and the rays of ∠BAC is 25.67°.

The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.

Given that, m∠BAC=51.34°.

Create an angle with half the measure of ∠BAC by drawing a ray in the interior of ∠BAC.

By drawing angle bisector, we get

m∠BAC'=m∠CAC' =51.34°/2

= 25.67°

Step-by-step explanation:

To estimate the number of new users that would be added during time period 7, we can use the Bass diffusion model, which is commonly used to model the adoption of new products or technologies.

The Bass diffusion model is given by the formula:

\(\[N(t) = \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot t)}}}\]\)

where:

- N(t) represents the cumulative number of adopters at time \(t\).

- p is the innovation parameter, representing the coefficient of innovation.

- q is the imitation parameter, representing the coefficient of imitation.

- e is the base of the natural logarithm.

Given a population size of 67 million, an innovation parameter of 0.005, and an imitation parameter of 0.84 for Color TV, we can substitute these values into the Bass diffusion model and calculate the number of new users added during time period 7.

\(\[N(7) - N(6) = \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot 7)}}} - \frac{{p \cdot q}}{{q + (p/q) \cdot e^{-((p+q) \cdot 6)}}}\]\)

Substituting the given values into the equation:

\(\[N(7) - N(6) = \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 7)}}} - \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 6)}}}\]\)

Evaluating the expression will give us the estimated number of new users added during time period 7.

In LaTeX, the solution can be represented as:

\(\[N(7) - N(6) = \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 7)}}} - \frac{{0.005 \cdot 0.84}}{{0.84 + (0.005/0.84) \cdot e^{-((0.005+0.84) \cdot 6)}}}\]\)

After evaluating this expression, you will obtain the estimated number of new users added during time period 7.

The net income for Griffin's Goat Farm, Inc., was \(\$184,340\).

The operating cash flow (OCF) for Kerber's Tennis Shop, we can use the following formula:

\(OCF = EBIT + Depreciation - Taxes + \triangle Working Capital\)

where EBIT is earnings before interest and taxes.

Calculate EBIT by subtracting interest expense from operating income:

EBIT = Operating Income - Interest Expense

We do not have the information for operating income, but we can use the fact that interest expense was. \(\$165,000\) to calculate EBIT.

EBIT = Interest Expense / (1 - Tax Rate)

= \(\$165,000 / (1 - 0)\)

= \(\$165,000\)

Calculate the change in working capital (Δ Working Capital). We are told that the company reduced its net working capital investment by \(\$69,000\), which means that working capital increased by  \(\$69,000\).

Therefore:

\(\triangle Working Capital = \$69,000\)

Now, we can calculate OCF:

OCF = EBIT + Depreciation - Taxes + Δ Working Capital

=\(\$165,000 + 0 - 0 +\ $69,000\)

=\(\$234,000\)

Therefore, the firm’s 2018 operating cash flow (OCF) was \(\$234,000\) .

To calculate the net income for Griffin's Goat Farm, we can use the following formula:

Net Income = EBIT - Interest Expense - Taxes

where EBIT is earnings before interest and taxes. We can calculate EBIT as:

EBIT = Sales - Costs - Depreciation

= \(\$686,000 - \$332,000 - \$65,000\)

=\(\$289,000\)

Next, we need to calculate taxes. We are given a tax rate of 24%, so:

Taxes = Tax Rate x (EBIT - Depreciation)

= \(0.24 \times (\$289,000 - \$65,000)= \$56,160\)

Now, we can calculate net income:

Net Income = EBIT - Interest Expense - Taxes

= \(\$289,000 - \$48,500 - \$56,160= \$184,340\)

The line integral of the function x sin(y z) ds on the curve c, which is defined by the parametric equations x = t², y = t³, z = t⁴, 0 ≤ t ≤ 3, can be calculated as follows:

First, we need to find the derivative of each parameter and the differential length of the curve.

\(ds = √[dx² + dy² + dz²] = √[(2t)² + (3t²)² + (4t³)²] dt = √(29t⁴) dt\)

We have to substitute the given expressions of x, y, z, and ds in the given function as follows:

\(x sin(y z) ds = (t²) sin[(t³)(t⁴)] √(29t⁴) dt = (t²) sin(t⁷) √(29t⁴) dt\)

Finally, we have to integrate this expression over the range 0 ≤ t ≤ 3 to obtain the value of the line integral using a calculator or computer algebra system:

\(∫₀³ (t²) sin(t⁷) √(29t⁴) dt ≈ 0.9045\)(correct to four decimal places).

The two possibilities for its x component is ±53.9 units, and its direction is θ=26.60°

The two possibilities for its x component which is given as :

Using an equation, we have

⇒\(z^{2} =x^{2} +y^{2}\)

\(x=\sqrt{z^{2}-y^{2} }\)

where, z = magnitude of z component = 86

y = magnitude of y component = - 67

then, we get

⇒\(x=\sqrt{86^{2}-67^{2} }\)

⇒\(x = \sqrt{2907}\)

⇒x = ±53.9 units

Assuming the x component is known to be positive, specify the magnitude of the vector which, if we add it to the original one, would give a resultant vector that is 80 units long and points entirely in the −x direction.

Resultant x-component = Sum of x-components of the 86-unit vector and that of the unknown vector.

⇒-80 = +53.9 + u

⇒-80-53.9 = u

⇒u = -133.9 units

Resultant y-component = Sum of y-components of the 86-unit vector and that of the unknown vector.

⇒0 = -67 + v

⇒0 + 67 = v

⇒v = +67 units

Magnitude of unknown vector is given by,

⇒\(Z = \sqrt{u^{2}+v^{2} }\)

⇒\(Z = \sqrt{(-133.9)^2 + (67)^{2} }\)

⇒Z = 149.7 units

And its direction is given by,

⇒ \(\theta\) = tan-1 (67 / -133.9)

⇒ \(\theta\) = tan-1 (-0.5003734)

⇒ \(\theta\) = 26.60°

Therefore, the two possibilities for its x component is ±53.9 units, and its direction is θ=26.60°
