find the area inside the larger loop and outside the smaller loop of the limaçon r = 1 2 + cos(θ).

Answers

Answer 1

To find the area inside the larger loop and outside the smaller loop of the limaçon r = 1 2 + cos(θ), we need to first visualize the graph of the limaçon.

The equation r = 1 2 + cos(θ) represents a curve that resembles a snail shell or a heart shape with a loop inside another loop. To find the area inside the larger loop and outside the smaller loop, we need to set up the integral using the polar coordinates.

The formula for the area enclosed by a polar curve is given by:
A = 1/2 ∫(θ2-θ1) (r2-r1)² dθ, where r2 is the outer curve, r1 is the inner curve, and θ1 and θ2 are the angles where the curves intersect.


In this case, the inner curve is r = 1 - cos(θ), and the outer curve is r = 1/2 + cos(θ). The curves intersect when cos(θ) = 1/2 or θ = π/3 and θ = 5π/3.
So, we need to split the integral into two parts, one for θ = π/3 to θ = 5π/3, and another for θ = 5π/3 to θ = π/3.

This is because the outer curve becomes the inner curve and vice versa when we cross the angle θ = 5π/3. For the area inside the larger loop and outside the smaller loop, we need to subtract the area enclosed by the inner curve from the area enclosed by the outer curve.


Using the formula above and plugging in the values, we get:
A = 1/2 ∫(5π/3-π/3) [(1/2 + cos(θ))² - (1-cos(θ))²] dθ


Simplifying this integral, we get:
A = 1/2 ∫(5π/3-π/3) [5/4 + 2cos(θ)] dθ
A = 5/8 [θ + sin(θ)](5π/3-π/3)
A = 5/8 [4π/3 + sin(4π/3) - (π/3 + sin(π/3))]
A = 5/8 [4π/3 - √3/2]
A = 5π/6 - (5/16)√3
Therefore, the area inside the larger loop and outside the smaller loop of the limaçon r = 1 2 + cos(θ) is 5π/6 - (5/16)√3.

Answer 2
Final answer:

To find the area inside the larger loop and outside the smaller loop of the limaçon r = 1 + 2cos(θ), use the formula for finding the area enclosed by a polar curve.

Explanation:122π/3∫0(12+cosθ)2dθ, r=(1/2)+cos\u0026#952, , 1, 2, cos, , Find

The general formula is A = (1/2)∫(r^2)dθ, where r is the equation of the curve. In this case, we need to find the area between two curves: the larger loop given by r = 1 + 2cos(θ) and the smaller loop given by r = 1. To find the limits of integration, we need to find the values of θ where the two curves intersect. After finding the values of θ where the curves intersect, we can integrate the difference between the two equations r = 1 + 2cos(θ) and r = 1 with respect to θ.

9.a. Find the H.C.F. of: [3] x² - y² - 2yz - z² and y² - z² - 2zx - x²​

Answers

Answer:

We can rewrite the given expressions as:

(3x² - y² - 2yz - z²) and (y² - z² - 2zx - x²)

To find the H.C.F., we can use the Euclidean algorithm. We start by dividing the first expression by the second expression:

(3x² - y² - 2yz - z²) ÷ (y² - z² - 2zx - x²)

Using long division or synthetic division, we get:

(3x² - y² - 2yz - z²) = (3x + y + z)(x - y + z) + 2y(x - z)

Therefore, the remainder is 2y(x - z). We can now divide the second expression by this remainder:

(y² - z² - 2zx - x²) ÷ 2y(x - z)

Using long division or synthetic division, we get:

(y² - z² - 2zx - x²) = -x(x - y + z) + z(x - y + z)

Therefore, the remainder is z(x - y + z).

Since the second remainder is not zero, we need to continue with the algorithm. Now we divide the remainder 2y(x - z) by the remainder z(x - y + z):

2y(x - z) ÷ z(x - y + z)

Using long division or synthetic division, we get:

2y(x - z) = 2y(x - y + z) - 2y²

Therefore, the remainder is -2y². Now we divide the previous remainder z(x - y + z) by this new remainder:

z(x - y + z) ÷ (-2y²)

Using long division or synthetic division, we get:

z(x - y + z) = -1(-2y²) + z²

Therefore, the H.C.F. of the original expressions is the absolute value of the last remainder, which is |-2y²| = 2y².

Therefore, the H.C.F. of (3x² - y² - 2yz - z²) and (y² - z² - 2zx - x²) is 2y².

what sample size should we select if we wish to develop a 90% confidence interval for the average diameter

Answers

The sample size required if we wish to develop a 90% confidence interval for the average diameter is more than 0.1 units. 

To decide the test estimate required for a 90% certainty interim for the normal distance across, we have to know the taking after :

1. The level of certainty (which is 90% in this case).

2. The standard deviation of the populace (which we'll expect is known).

3. The margin of error (which is the greatest separation between the test cruel and the genuine populace cruel that we're willing to endure).

Assuming we know the standard deviation of the populace, ready to utilize the equation:

n = (z²* σ²) / E²

where:

n is the test measure

z is the z-score compared to the level of certainty (which is 1.645 for 90% certainty)

σ is the standard deviation of the populace

E is the edge of mistake

We ought to select esteem for E, which speaks to the most extreme separation between the test cruel and the genuine populace cruel(mean) that we're willing to endure.

For case, in the event that we need the interim to have a width of no more than 0.1 units, at that point we would select E = 0.1/2 = 0.05.

So, stopping within the values we know, we get:

n = (1.645² * σ²) / E²

In case we accept that the standard deviation of the populace is 0.5 units (fair as a case), at that point we get:

n = (1.645² * 0.5²) / 0.05²

n = 67.65

If c is a nonzero constant such that x^2+cx+9c is equal to the square of a binomial, then what is c?

Answers

Answer:

c = 6.

Step-by-step explanation:

x^2+cx+9 = (x + b)^2     where b is a constant

x^2 + cx + 9 = x^1 + 2bx + b^2

so 2b = c

and b^2 = 9

So b = 3

and c = 2*b = 6

To solve this problem, we will use the fact that the square of a binomial (a+b)^2 is equal to a^2 + 2ab + b^2.

Let's start by assuming that x^2 + cx + 9c is the square of a binomial (a+b)^2. Expanding (a+b)^2 using the formula above, we get:

(a+b)^2 = a^2 + 2ab + b^2

If we compare this to x^2 + cx + 9c, we see that:

a^2 = x^2      (1)
2ab = cx       (2)
b^2 = 9c        (3)

From (1), we get a = ±√x^2 = ±x.

Substituting a = ±x into (2), we get:

2(±x)b = cx

Simplifying this equation, we get:

b = ±(c/2)

Substituting a = ±x and b = ±(c/2) into (3), we get:

x^2 + (c/2)^2 = 9c

Multiplying both sides by 4, we get:

4x^2 + c^2 = 36c

Rearranging this equation, we get:

4x^2 - 36c + c^2 = 0

This is a quadratic equation in c. Using the quadratic formula, we get:

c = (36 ± √(36^2 - 4(4)(c^2))) / (2(4))

Simplifying this equation, we get:

c = (9 ± √(81 - c^2)) / 2

Since c is nonzero, we can ignore the solution c = 0. Therefore, we have:

c = (9 + √(81 - c^2)) / 2   or   c = (9 - √(81 - c^2)) / 2

We can check that both solutions satisfy the original condition that x^2 + cx + 9c is the square of a binomial.

However, we need to ensure that the square root in each solution is real, which means that 81 - c^2 ≥ 0.

For the first solution, we have:

81 - c^2 ≥ 0

c^2 ≤ 81

|c| ≤ 9

Therefore, the first solution is valid for c such that -9 ≤ c ≤ 9.

For the second solution, we have:

81 - c^2 ≥ 0

c^2 ≤ 81

|c| ≥ 9

However, we already know that c is nonzero, so |c| > 0. Therefore, the second solution is not valid for any value of c.

Therefore, the only valid solution is:

c = (9 + √(81 - c^2)) / 2,   for -9 ≤ c ≤ 9.

I hope this helps! Let me know if you have any questions.
If x^2 + cx + 9c is equal to the square of a binomial, then it can be written in the form (x + A)^2, where A is a constant. Expanding the square of the binomial, we get:

(x + A)^2 = x^2 + 2Ax + A^2

Comparing this with the given expression, x^2 + cx + 9c, we can deduce the following:

2A = c and A^2 = 9c

We are asked to find the value of c. Using the first equation (2A = c), we can substitute c in the second equation:

A^2 = 9(2A)
A^2 = 18A

Since A is nonzero, we can divide both sides by A:

A = 18

Now, using the first equation, we can find the value of c:

c = 2A
c = 2(18)
c = 36

Therefore, the value of c is 36.

Type I error shows when we reject a null hypothesis which is actually true. Type II error shows when we fail to reject a null hypothesis which is actually false.

Increasing the sample size can decrease the probability of making a Type II error, as it increases the power of the hypothesis test. Probability of correctly rejecting a false null hypothesis is called power.

By increasing the sample size, we can increase the power of the test while maintaining the significance level (and thus the type I error) at its current level.

What are the monthly payments?

Answers

The monthly payments after the down payment are $186.58 per month.

What are the monthly payments?

We will first calculate amount of the down payment which is:

= 10% * 6,250.

= $625.

So, the financed amount for the purchase will be:

= $6,250 - $625

= $5,625.

We will now calculate the amount of sales tax where tax rate is 8.25%, this give us:

= $6,250 * 8.25%

= $515.63.

The total amount financed including sales tax is:

= $5,625 + $515.63

= $6,140.63.

To calculate the monthly payments, we can use the formula M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]

M = $6,140.63*  [ 0.005(1 + 0.005)^36 ] / [ (1 + 0.005)^36 – 1 ]

M = $6,140.63* 0.03042193745

a company receives customer satisfaction ratings on a scale from 0 to 10, inclusive. on the first six surveys that the company received, the average (arithmetic mean) of the ratings was 7.7. what is the least rating the company can receive on the seventh survey and still be able to have an average of at least 8 for the first 10 surveys? (round to the nearest tenth.)

Answers

The least amount of ratings the particular company can receive is 3 on the seventh survey and still be eligible to have an average of at least 8 for the first 10 surveys.

Here we have to implement basic algebraic application
Let us consider x as the  the least rating the company can get on the seventh survey.
The average of the first six surveys is 7.7, so their total score is 6 × 7.7 = 46.2.

The average of at least 8 for the first ten surveys, their total score should be at least 80.
So for the first ten surveys, their total score should be
80 = (46.2 + x + y)/10
Here
y = score for survey 8 and survey 9.

Evaluating for y
y = (80 - 46.2 - x × 2)/2
= (33.8 - x)/2.

As  each survey rating is an integer between 0 and 10 inclusive, we need to find the smallest integer value of x that makes y ≥ 0

Then, (33.8 - x)/2 >= 0.

What would the Volume and Surface area of a pentagonal pyramid be if the Apothem is 3 square root 2 and the height is 3

Answers

The volume of the Pentagonal pyramid is 8.25 units² and surface area is 12.2 units²

What is volume of a pyramid?

A Pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces.

The volume of of a pyramid is expressed as;

V = 1/3 b × h

where b is the area of the base

Area of the base = 1/2 nsa

where s is the side length and n is the number of sides and a is the apothem.

side length = apothem × 2tan(180/n)

= √3/2 × 2tan36

= √3 × tan36

= 1.26m

Therefore,

A = 1/2( 5 × 1.26 × √3/2)

A = 1/2 ( 5.5)

A = 2.75 units²

Volume of the pyramid = 2.75 × 3

= 8.25 units²

Area of a face = 1/2bh

= 1/2 × 1.26 × 3

= 3.78/2

= 1.88 units²

Total surface area = 1.88 × 5

= 9.45 units² + 2.75units²

= 12.2 units²

7.] A concrete walk 5 m wide is built around a grass court. The length of the court is 12 m more than its width. The area of the walk is 560 m^2. Find the dimensions of the grass court.

Answers

The sum of the areas of the two squares = 104

The perimeter of the triangle is 27.67

How to solve for the area

1. We have 5x)² - x²  = 96

next wer have to solve for x

25x²  - x²  = 96

x = 2

x²  = 2²  = 4

5x)² = 10²  = 100

sum of the areas = 4 + 100 = 104

2. b = a + 4

c = b + 5

ac + bc = 2a^2 + 124

substitute b and c from the relationships:

When we simplify we have 18a = 88

a = 44/9

b = a + 4 = 44/9 + 4 = 80/9

c = b + 5 = 80/9 + 5 = 125/9

perimeter = a + b + c:

= 44/9 + 80/9 + 125/9

= 249/9 = 27.67

14+5x -11= 7x+3-2x
what is it

Answers

The equation "14 + 5x -11 = 7x + 3 - 2x" has infinitely many solutions, so any value of "x" will satisfy the equation.

In order to solve for "x" in the equation "14 + 5x - 11 = 7x + 3 - 2x", we need to simplify the expression by combining like terms:

14 + 5x - 11 = 7x + 3 - 2x

Simplifying the LHS,

We get,

3 + 5x = 7x + 3 - 2x

Simplifying the RHS,

We get,

3 + 5x = 5x + 3

Subtracting 5x from both sides,

We get,

3 = 3

The equation simplifies to 3 = 3, which is always true.

This means that the equation has infinitely many solutions and that any value of "x" will satisfy the equation.

Therefore, there is no unique value of "x" that can be found from the equation.

Graphing quadratic equations

Answers

A graph of the given quadratic equation is shown below.

The axis of symmetry is equal to 3.

The vertex is equal to (3, -1).

What is the graph of a quadratic function?

In Mathematics and Geometry, the graph of a quadratic function would always form a parabolic curve because it is a u-shaped. Based on the graph of this quadratic function, we can logically deduce that the graph is an upward parabola because the coefficient of x² is positive and the value of "a" is greater than zero (0).

Since the leading coefficient (value of a) in the given quadratic function y = x² - 6x + 8 is positive 1, we can logically deduce that the parabola would open upward and the solution would be on the x-intercepts. Also, the value of the quadratic function f(x) would be minimum at -1.

In conclusion, the axis of symmetry is 3 while the vertex is given by the ordered pair (3, -1).

Answers

The equation of the line is written as y = (2/3)x + (14/3).

The equation of a line is a mathematical representation of the relationship between each point's x and y coordinates along a straight line.

Y = mx + b, where m is the line's slope and b is its y-intercept, is its mathematical formula (the point where the line intersects the y-axis). This equation allows us to rapidly calculate the y-coordinate of a point given its x-coordinate.

The equation of the line can be written as,

y = mx + c

The slope of the line is,

m = ( y₂ - y₁) / (x₂ - x₁)

m = ( 6 - 2 ) / ( 9-3 )

m = 2/3

The y-intercept is calculated as,

y = 2/3x + c

6 = (2/3) x 2 + c

c = 14/3

The equation of the line is,

y = 2/3x + 14/3

in the standard normal distribution, what is the proportion of values between negative infinity and 1 z-score?

Answers

Thus, the proportion of values between negative infinity and 1 z-score in the standard normal distribution is about 84.13%.

In the standard normal distribution, the proportion of values between negative infinity and 1 z-score can be determined using the cumulative distribution function (CDF) of the normal distribution.

The standard normal distribution, also known as the Z-distribution, has a mean (µ) of 0 and a standard deviation (σ) of 1. The proportion of values between negative infinity and any z-score corresponds to the area under the curve of the standard normal distribution up to that z-score.To find the proportion of values between negative infinity and 1 z-score, you can consult a Z-table or use a statistical calculator or software that provides the CDF for the standard normal distribution. The CDF value for a z-score of 1 is approximately 0.8413.Therefore, the proportion of values between negative infinity and 1 z-score in the standard normal distribution is about 84.13%. This means that 84.13% of the data points lie to the left of a z-score of 1 in a standard normal distribution.
