Answer:

y = 1/3 x + 5/3

Step-by-step explanation:

For rectangular to polar

x = rcosθ ... 1

y = rsinθ ... 2

Given the expression

r=5/3sinθ−cosθ

Cross multiply

r(3sinθ−cosθ) = 5

Expand

3rsinθ−rcosθ = 5 ..3

Substitute 1 and 2 into 3

3y - x = 5

Write in slope intercept form

3y = x + 5

Divide through by 3;

3y/3 = x/3 + 5/3

y = x/3 + 5/3

y = 1/3 x + 5/3

Hence the expression in slope-intercept form is y = 1/3 x + 5/3

Taking a difference, we can see that the trip to city C is 482.6 mi longer.

Here we know that the distance from city a to city b is 256.8 miles, and the distance from city a to city c is 739.4 miles

To find how much farther is the trip to city c than the trip to city b, we just need to take the difference between the two distances above.

That means that we need to take the distance to city c and subtract the distance to city b.

We will get:

739.4 mi -  256.8 mi = 482.6 mi

The trip to city C is 482.6 mi more than the trip to city B.

This is a simple probability problem to solve, first, we need to know how many cookies we have inside the bag. So we have 8 chocolate chip cookies + 4 peanut butter cookies + 9 sugar cookies + 6 oatmeal cookies = 27 cookies (total). Once we have the total we can see the probability to first randomly select a chocolate chip cookie is P (first chocolate chip cookie) = 8/27 (we just have 8 chances to select a chocolate chip cookie between 27 cookies).

After we select a chocolate chip cookie and eat it, now we just have 26 cookies inside the bag. So our probability to select randomly a sugar cookie is P (sugar cookie second) = 9/26 (we just have 9 chances to select a sugar cookie between 26 cookies). Now we just need to combine those two probabilities, and to do that as a sequence (probability 1 first, next probability 2) we use the product operator *. So P(chocolate chip cookie first and sugar cookie second) = P (first chocolate chip cookie) * P (sugar cookie second) = (8/27) * (9/26) = 72/702.

Finally, our final answer is P(chocolate chip cookie first and sugar cookie second) = 0.1025 (approximately).

The indefinite integral of \(1/(16-x^2)^{(3/2)}\) dx using the substitution x = 4 sin(t) is (1/8) arcsin(x/4) - \((1/16)x(16-x^2)^{0.5}\) + C here C is the constant of integration.
Let us take x = 4 sin(t), then dx/dt = 4 cos(t), and x² = 16 sin²(t). Substituting these values in the integral, we get:

\(\int\limits 1/(16-x^{2})^{(3/2}) dx\) =\(\int\limits1/(16-16sin^{2}(t))^{(3/2)} * 4cos(t) dt\)

= ∫1/16cos³(t) dt

= (1/16) ∫sec³(t) dt

= (1/16) (1/2 sec(t) tan(t) + 1/2 ln|sec(t)+tan(t)| + C)

Substituting back x = 4 sin(t), we get:

\(\int\limits1/(16-x^2)^{(3/2)}\) dx = (1/8) \(arcsin(x/4) - (1/16)x(16-x^{2})^{0.5}\) + C

To find the value of k for which the system of equations has no solution, we need to examine the coefficients of x and y in the equations.

The first paragraph provides a concise summary of the answer, while the second paragraph explains the solution in more detail.

For the system of equations to have no solution, the coefficients of x and y in the equations must be proportional. In other words, the ratios of the coefficients should be equal for both equations. If the coefficients are not proportional, the system will have a unique solution. Therefore, to determine the value of k for which the system has no solution, we need to examine the coefficients of x and y in the equations and find the condition where they are proportional.

In more detail, let's consider the system of equations as:

Equation 1: ax + by = c

Equation 2: dx + ey = f

For the system to have no solution, the ratios of the coefficients a/d and b/e should be equal to each other. In other words, a/d = b/e. Solving this equation will give us the condition for k that results in no solution. The specific values of a, b, d, and e will depend on the given system of equations. By finding the appropriate condition, we can determine the value of k that satisfies this requirement and leads to no solution for the system of equations.

The point (-6, 9) is not a solution of the system of equations. Highlighting the importance of verifying each equation individually when determining if a point is a solution.

To determine if the point (-6, 9) is a solution of the given system of equations, we substitute the values of x and y into the equations and check if both equations are satisfied.

For the first equation, substituting x = -6 and y = 9 gives:

6(-6) + 9 = -36 + 9 = -27.

For the second equation, substituting x = -6 and y = 9 gives:

5(-6) - 9 = -30 - 9 = -39.

Since the value obtained in the first equation (-27) does not match the value in the second equation (-39), we can conclude that (-6, 9) is not a solution of the system. Therefore, the answer is "No".

In this case, the solution is not consistent with both equations of the system, highlighting the importance of verifying each equation individually when determining if a point is a solution.

Answer: Personally I would do option "B" 2 1/3 because it sounds right.

To obtain the periodic function by replicating this over intervals of length 10, we can write the extended function as  f(x) = 5((x mod 10)^2) and as the function 5(x) = x² is even, its periodic extension f(x) is also even, meaning it is symmetric about the y-axis.

Since the period is 10, we can write the extended function as:

f(x) = 5(\((x mod 10)^2\)),

where "mod" denotes the modulo operator, which gives the remainder after division.

In other words, for any value of x, we first find its remainder when divided by 10 (i.e., the value of x "wrapped" around the interval [0,10]). Then we evaluate the original function 5(x) = x² at this wrapped value.

For example, if x = 8, then its wrapped value is 8 mod 10 = 8, so we have:

f(8) = 5((\(8)^2\)) = 5(64) = 320.

Similarly, if x = 13, then its wrapped value is 13 mod 10 = 3, so we have:

f(13) = 5(\((3)^2\)) = 5(9) = 45.

The probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

To find the probability that the average number of hours of overtime worked by a random sample of 140 employees exceeds 20 hours, we can use the Central Limit Theorem (CLT). The CLT states that for a large enough sample size, the sampling distribution of the sample mean approaches a normal distribution, regardless of the shape of the population distribution.

Given that the population mean is 18.9 hours and the population standard deviation is 7.8 hours, we can calculate the standard error of the mean using the formula: standard error = population standard deviation / sqrt(sample size).

For this problem, the sample size is 140, so the standard error is 7.8 / sqrt(140) ≈ 0.659.

To calculate the probability, we need to standardize the sample mean using the z-score formula: z = (sample mean - population mean) / standard error.

In this case, the sample mean is 20 hours, the population mean is 18.9 hours, and the standard error is 0.659. Plugging these values into the formula, we get z = (20 - 18.9) / 0.659 ≈ 1.71.

Now, we can use a standard normal distribution table or calculator to find the probability associated with a z-score of 1.71. Looking up this value in the table, we find that the probability is approximately 0.9564.

Therefore, the probability that the average number of hours of overtime worked last month by a random sample of 140 employees in the city exceeds 20 hours is approximately 0.9564, or 95.64%.

Step-by-step explanation:

3) 5x/6 − ( 2x − 1/2 ) + 4 − 2x/3 = 11

Step 1: Simplify both sides of the equation.

5x/6 − ( 2x−1/2 ) + 4 − 2x/3 = 11

5x/6 + − x + 1/2 + − 2/3x + 4/3 = 11  ( Distribute )

5/6x + − x + 1/2 + − 2/3x + 4/3 = 11

( 5/6x + − x + − 2/3x ) + ( 1/2 + 4/3 ) = 11  ( Combine Like Terms )

−5/6x + 11/6 = 11

Step 2: Subtract 11/6 from both sides.

−5/6x + 11/6 − 11/6 = 11 − 11/6

−5/6x = 55/6

Step 3: Multiply both sides by 6/(-5).

( 6/−5 ) * ( −5/6x ) = ( 6/−5 ) * ( 55/6 )

The eigenvectors of the given matrix are \(v_1\) = [3/4, 1] and \(v_2\) = [1, 1].

To find the eigenvectors of a matrix, we need to solve the equation (A - λI)v = 0, where A is the matrix, λ is the eigenvalue, I is the identity matrix, and v is the eigenvector.

Given the matrix A:

A = \(\begin{bmatrix}11 & -12 \\16 & -17 \\\end{bmatrix}\)

We are looking for the eigenvectors corresponding to eigenvalues \(\lambda_1\) = -5 and \(\lambda_2\) = -1.

For \(\lambda_1\) = -5:

We solve the equation (A - (-5)I)\(v_1\) = 0:

(A - (-5)I)\(v_1\) = [[11, -12],

[16, -17]] - [[-5, 0],

[0, -5]]\(v_1\)

Simplifying, we have:

[[16, -12],

[16, -12]] \(v_1\) = [[0],

[0]]

This leads to the following system of equations:

16u - 12b = 0

16u - 12b = 0

We can see that these equations are dependent on each other, so we have one free variable. Let's choose b = 1 to make calculations easier.

From the first equation, we have:

16u - 12(1) = 0

16u - 12 = 0

16u = 12

u = 12/16

u = 3/4

Therefore, the eigenvector corresponding to eigenvalue \(\lambda_1\) = -5 is:

\(v_1\) = [u] = [3/4]

[1]

For \(\lambda_2\) = -1:

We solve the equation (A - (-1)I)\(v_2\) = 0:

(A - (-1)I)\(v_2\) = [[11, -12],

[16, -17]] - [[-1, 0],

[0, -1]]\(v_2\)

Simplifying, we have:

[[12, -12],

[16, -16]]\(v_2\) = [[0],

[0]]

This leads to the following system of equations:

12u - 12b = 0

16u - 16b = 0

Dividing the second equation by 4, we obtain:

4u - 4b = 0

From the first equation, we have:

12u - 12(1) = 0

12u - 12 = 0

12u = 12

u = 12/12

u = 1

Substituting u = 1 into 4u - 4b = 0, we have:

4(1) - 4b = 0

4 - 4b = 0

-4b = -4

b = -4/-4

b = 1

Therefore, the eigenvector corresponding to eigenvalue \(\lambda_2\) = -1 is:

\(v_2\) = [u] = [1]

[1]

In summary, the eigenvectors corresponding to the eigenvalues \(\lambda_1\) = -5 and \(\lambda_2\) = -1 are:

\(v_1\) = [3/4]

\(v_2\) = [1]

I would choose the western side to climb because it is less steep then others.

In mathematics, a line's steepness is determined by its slope (or gradient). The slope is the ratio of any two points on a line's vertical and horizontal distances. A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope's absolute value serves as a gauge for a line's steepness, incline, or grade. A steeper line is indicated by a slope with a higher absolute value. A line can be drawn with one of four directions: upward, downward, horizontal, or vertical. If a line rises from left to right, it is said to be increasing.
