The Blackburn family has a square field where they keep their cattle. The area of the field is 40,000 ft square, and Mr. Blackburn wants to put a fence diagonally through the field. What should the length of the fence be?

Answers

Answer 1

If area of cattle's "square-field" is 40000 ft², and Mr. Blackburn is constructing a fence diagonal in the field, then length of cattle field's fence should be 282.84 ft.

The area of the Blackburn's family cattle square-field is 40000 ft²,

So, We First, equate this area with area formula,

On Equating ,We get,

⇒ (side × side) = 40000,,

⇒ side is 200 ft,

Now, we substitute the "side-length" of field as 200 ft, in the formula for diagonal of a square,

we get,

⇒ Length of cattle-field's diagonal is = (side)√2,

⇒ Length of cattle-field's diagonal is = (200)√2,

⇒ Length of cattle-field's diagonal is ≈ 282.84 ft.

Therefore, the length of cattle field's fence is 282.84 ft.

Non self supporting ladders must be placed or positioned at an angle where the horizontal distance.

Answers

When using non-self supporting ladders, it is essential to ensure they are positioned at an appropriate angle to provide the necessary stability and safety for the user.

The angle at which the ladder is placed is critical because it determines the distance between the base of the ladder and the wall or surface it is resting against, In general, non-self supporting ladders must be positioned at an angle where the horizontal distance is no less than 1/4 of the ladder's working length.

For example, if you are using a 12-foot ladder, the base of the ladder should be positioned 3 feet away from the wall or surface it is leaning against. This ensures that the ladder is stable and will not slip or tip over during use.



The angle of the ladder is also important because it affects the amount of force and pressure exerted on the ladder and the surface it is resting against. If the ladder is placed at too steep of an angle, the weight of the user can cause the ladder to slide or fall backward. Conversely, if the ladder is placed at too shallow of an angle, the weight of the user can cause the ladder to slide or fall forward.



Therefore, it is crucial to position non-self supporting ladders at an appropriate angle to ensure the safety of the user. Always follow the manufacturer's guidelines and safety instructions when using ladders and avoid taking unnecessary risks. Remember to take your time and stay focused on the task at hand to avoid accidents and injuries.

Find the volume of the solid whose base is the region bounded by the ellipse 4x^2+9y^2=36 if the cross sections taken perpendicular to the y-axis are isosceles right triangles with the hypotenuse lying in the base

Answers

The volume of the solid is [tex]\frac{32}{3}[/tex] cubic units.

To find the volume of the solid, we need to integrate the area of each cross section taken perpendicular to the y-axis over the range of y-values that the ellipse covers.

the height of each cross section will be equal to the y-coordinate of the ellipse at that point, since the triangles are isosceles and right-angled. The base of each cross section will be twice the height, since the triangles are isosceles, and the hypotenuse will lie in the ellipse.

So, for a given y-value, the area of the cross section will be:

[tex]A(y) = \frac{1}{2} \cdot 2y \cdot y = y^2[/tex]

To find the limits of integration for y, we need to find the y-coordinates of the points where the ellipse intersects the y-axis. We can do this by setting x = 0 in the equation of the ellipse:

[tex]4x^2 + 9y^2 = 36\\9y^2 = 36\\y^2 = 4\\y = \pm 2[/tex]

So, the limits of integration for y are -2 and 2.

The volume of the solid can now be found by integrating the area of the cross sections over the range of y-values:

[tex]V = \int_{-2}^{2} A(y) dy\\V = \int_{-2}^{2} y^2 dy\\\\V = \frac{1}{3}y^3 \Bigg|_{-2}^{2}\\V = \frac{1}{3}(2^3 - (-2)^3)\\V = \frac{32}{3}[/tex]

The solution to the equation is t = log(146)/8, and the approximate value of t is 0.270.

To solve the equation 0.5 *[tex]10^{8t}[/tex] = 73 for t, we can first simplify the left side of the equation by dividing both sides by 0.5 * 10^8:

[tex]10^{8t}[/tex] = 146

Next, we can take the logarithm of both sides of the equation using base 10:

[tex]log(10^{8t}) = log(146)[/tex]

Using the property of logarithms that says [tex]log(a^{b} ) = b*log(a)[/tex], we can simplify the left side of the equation:

8t * log(10) = log(146)

Since log(10) = 1, we can further simplify the equation:

8t = log(146)

Finally, we can solve for t by dividing both sides by 8:

t = log(146)/8

t = 2.164/8

$n$ is a four-digit positive integer. dividing $n$ by $9$, the remainder is $5$. dividing $n$ by $7$, the remainder is $3$. dividing $n$ by $5$, the remainder is $1$. what is the smallest possible value of $n$?

Answers

To find the smallest possible value of $n$, we need to find the smallest value that satisfies all three conditions.

From the first condition, we know that $n = 9a + 5$ for some positive integer $a$.
From the second condition, we know that $n = 7b + 3$ for some positive integer $b$.
From the third condition, we know that $n = 5c + 1$ for some positive integer $c$.
We can set these equations equal to each other and solve for $n$:
$9a + 5 = 7b + 3 = 5c + 1$
Starting with the first two expressions:
$9a + 5 = 7b + 3 \Rightarrow 9a + 2 = 7b$
The smallest values of $a$ and $b$ that satisfy this equation are $a=2$ and $b=3$, which gives us $n = 9(2) + 5 = 7(3) + 3 = 23$.
Now we need to check if this value of $n$ satisfies the third condition:
$n = 23 \not= 5c + 1$ for any positive integer $c$.
So we need to try the next possible value of $a$ and $b$:
$9a + 5 = 5c + 1 \Righteous 9a = 5c - 4$
$7b + 3 = 5c + 1 \Righteous 7b = 5c - 2$
If we add 9 times the second equation to 7 times the first equation, we get:
$63b + 27 + 49a + 35 = 63b + 45c - 36 + 35b - 14$
Simplifying:
$49a + 98b = 45c - 23$
$7a + 14b = 5c - 3$
$7(a + 2b) = 5(c - 1)$
So the smallest possible value of $c$ is 2, which gives us $a + 2b = 2$. The smallest values of $a$ and $b$ that satisfy this equation are $a=1$ and $b=1$, which gives us $n = 9(1) + 5 = 7(1) + 3 = 5(2) + 1 = 46$.
Therefore, the smallest possible value of $n$ is $\boxed{46}$.

To find the smallest possible value of $n$ which is a four-digit positive integer such that dividing $n$ by $9$, the remainder is $5$, dividing $n$ by $7$, the remainder is $3$, and dividing $n$ by $5$, the remainder is $1$, follow these steps:
Step 1: Write down the congruences based on the given information.
$n \equiv 5 \pmod{9}$
$n \equiv 3 \pmod{7}$
$n \equiv 1 \pmod{5}$
Step 2: Use the Chinese Remainder Theorem (CRT) to solve the system of congruences. The CRT states that for pairwise coprime moduli, there exists a unique solution modulo their product.
Step 3: Compute the product of the moduli.
$M = 9 \times 7 \times 5 = 315$
Step 4: Compute the partial products.
$M_1 = M/9 = 35$
$M_2 = M/7 = 45$
$M_3 = M/5 = 63$
Step 5: Find the modular inverses.
$M_1^{-1} \equiv 35^{-1} \pmod{9} \equiv 2 \pmod{9}$
$M_2^{-1} \equiv 45^{-1} \pmod{7} \equiv 4 \pmod{7}$
$M_3^{-1} \equiv 63^{-1} \pmod{5} \equiv 3 \pmod{5}$
Step 6: Compute the solution.
$n = (5 \times 35 \times 2) + (3 \times 45 \times 4) + (1 \times 63 \times 3) = 350 + 540 + 189 = 1079$
Step 7: Check that the solution is a four-digit positive integer. Since 1079 is a three-digit number, add the product of the moduli (315) to the solution to obtain the smallest four-digit positive integer that satisfies the conditions.
$n = 1079 + 315 = 1394$
The smallest possible value of $n$ is 1394.

from a group of 12 students, we want to select a random sample of 5 students to serve on a university committee. how many combinations of random samples of 5 students can be selected? group of answer choices 60 95,040 25 792

Answers

The number of  combinations of random samples  of 5 students can be selected is 56, here, the correct answer is 60.

To find the number of combinations of selecting a random sample of 5 students from a group of 12 students, you can use the formula for combinations which is:

C(n, k) = n! / (k!(n-k)!)

where C(n, k) represents the number of combinations, n is the total number of students (12 in this case), and k is the number of students to be selected (5 in this case). The exclamation mark (!) represents a factorial, which means the product of all positive integers up to that number.

Using the formula, we can calculate the number of combinations:

C(12, 5) = 12! / (5!(12-5)!)
= 12! / (5!7!)
= (12×11×10×9×8) / (5×4×3×2×1)
= 95,040 / 1,680
= 56.52 (rounded)

Since the number of combinations must be a whole number, the correct answer is 56, which is not among the given answer choices. However, the closest answer choice to 56 is 60.

Answer: We can use the formula for sample size calculation for estimating a population proportion:

n = (z^2 * p * (1 - p)) / E^2

where:

z = the z-score corresponding to the desired level of confidence

p = the estimated proportion from the population (0.13 in this case)

E = the desired margin of error (0.05 in this case)

Substituting the given values, we get:

n = (z^2 * p * (1 - p)) / E^2

n = (2.326^2 * 0.13 * (1 - 0.13)) / 0.05^2

The price of a tablet was increased from $180 to $207. By what percentage was the price of the tablet increased?

Answers

Answer: The increase percentage of tablet was 15%

Step-by-step explanation:

The price of the a tablet was increased from $180 to $207

Old Price = $180

New Price = $207

Increased price (Change in price) = New Price - Old price

Express the rational function as a sum or difference of two simpler rational expressions. 9x 1 x2

Express the rational function 2x⁴/(x² - 2x) as a sum or difference of two simpler rational expressions:

2x⁴/(x² - 2x) = 2x² + 4x + 8 + 16/(x - 2).

The given expression is,

2x⁴/(x² - 2x)

simplifying we get,

= 2x⁴/x(x - 2) [taking 'x' as common from both the term of denominator]

= 2x³/(x - 2) [Cancelling the same value from numerator and denominator]

Now if we divide '2x³' by (x-2) we get

Quotient = 2x² + 4x + 8

Remainder = 16

So from the division algorithm we know that,

Dividend = Divisor*Quotient + Remainder

Here Dividend = 2x³ and Divisor = x - 2

So, 2x³ = (x - 2)*(2x² + 4x + 8 ) + 16

Now, 2x⁴/(x² - 2x)

= 2x³/(x - 2)

= ((x - 2)*(2x² + 4x + 8 ) + 16)/(x - 2)

= ((x - 2)*(2x² + 4x + 8) )/(x - 2) + 16/(x - 2)

= 2x² + 4x + 8 + 16/(x - 2).

A ladder leans against a vertical wall at slope of 9/4. The tip of the ladder is 13.7 feet from the ground. What is the length of the ladder?

Answers

The length of the ladder is approximately 17.4 feet.

Let's call the length of the ladder "L". We can use the Pythagorean theorem to solve for L.

We know that the ladder is leaning against a vertical wall at a slope of 9/4, which means that for every 9 units the ladder goes up, it goes 4 units away from the wall. We can use this to set up a right triangle with the ladder as the hypotenuse:

To know the sides use pythagorean theorem. The vertical distance from the ground to the tip of the ladder is 13.7 feet, so the length of the side opposite the angle θ (the angle between the ladder and the ground) is 13.7. The length of the side adjacent to θ (the distance from the wall to the base of the ladder) is (9/4) times the length of the opposite side.

Using the Pythagorean theorem, we have:

L² = (9/4 * 13.7)² + (13.7)²

L² = 114.96 + 187.69

L² = 302.65

L = √(302.65)

L ≈ 17.4

Therefore, the length of the ladder is approximately 17.4 feet.

For a andrea's record label released her new album, the simplified inequality of absolute value inequality in terms of t is equals to the t ≥ 10. The graph which represents the inequlity is option(b).

Andrea's record label released her new album. Now, she wants to know the sales of at least $20,000 per week. The equation where sales will be at least 20,000 amount is written as 20,000≤ 1000(-2|t - 15| + 30). We have to solve this inequality. Now, the inequality is written as 20,000 ≤ 1000(-2|t - 15| + 30)

dividing by 1000 both sides, [tex] \frac{20,000 }{1000} ≤ (-2|t - 15| + 30) [/tex]

=> 20 ≤ (-2|t - 15| + 30)

Substracts 20 from both sides

=> 20- 30 ≤ -2|t - 15| + 30 - 30

=> -10 ≤ -2|t - 15|

dividing by (-2) by both sides in above equation,

=> 5 ≤ | t - 15 |

=> -(t - 15) ≤ 5 ≤ (t - 15)

=> - t + 15 ≤ 5 ≤ t - 15

=> - t + 15≤ 5 or 5 ≤ t - 15

=> -t ≤ - 10 or 15 ≤ t

=> t ≥ 10

Hence, required graph is present in option(b)

A population of three-toed sloths in a tropical forest has a maximum per capita growth rate of 0.8 per year. The population size is limited by the carrying capacity of the forest, which is 500 individuals. Which of the following is the growth rate of the sloth population when the population is made up of 275 individuals?

Answers

The growth rate of the sloth population when the population is made up of 275 individuals is 99 individuals per year.

To calculate the growth rate of the three-toed sloth population when there are 275 individuals, we will use the logistic growth model formula:

Growth rate = r * N * (1 - N/K)

where r is the maximum per capita growth rate (0.8 per year), N is the current population size (275 individuals), and K is the carrying capacity of the forest (500 individuals).

Growth rate = 0.8 * 275 * (1 - 275/500)
Growth rate = 0.8 * 275 * (1 - 0.55)
Growth rate = 0.8 * 275 * 0.45
Growth rate ≈ 99 individuals per year

So, the growth rate of the sloth population when the population is made up of 275 individuals is approximately 99 individuals per year.

Answers

The given triangle is an isosceles triangle, where two sides and two angles are congruent. The value of x is 46 degrees.

How to calculate the value of x

It should be noted that because the triangle is isosceles, and the base angles are x.

The following equation can be used to solve for x

x + x + 88 = 180 --- sum of angles in a triangle

So, we have:

2x + 88 = 180

Collect like terms

2x = 180 - 88

2x = 92

Divide both sides by 2

if s is the part of the sphere that lies above the cone in the first octant, find the following: sqrt(x^2 y^2)

Answers

√(x² y²) = √[(r² + 2x² y²)/(1 + k²)], This gives us the value of √(x² y²) for the part of the sphere that lies above the cone in the first octant.

To find the value of √(x²y²), we need to know the equation of the surface that defines the part of the sphere and the cone in the first octant.

Let's assume that the sphere has radius r and its center is at the origin. Then, the equation of the sphere is:

x² + y² + z² = r²

Since the part of the sphere that lies above the cone is in the first octant, we can limit our analysis to the region where x, y, and z are all positive.

Now, let's consider the cone. We can assume that the cone has its vertex at the origin and its axis is along the z-axis. The equation of the cone can be written as:

z = k*√(x² + y²)

where k is a constant that depends on the angle of the cone.

To find the value of s√(x² y²), we need to find the point (x,y,z) that lies on the surface that defines the part of the sphere and the cone. Since the point lies on both surfaces, it must satisfy both equations:

x² + y² + z² = r²     (equation of sphere)

z = k*√(x² + y²)     (equation of cone)

We can eliminate z from these equations by substituting the equation of the cone into the equation of the sphere:

x² + y² + (k*√(x² + y²))² = r²

Simplifying this equation, we get:

x² + y² + k²*(x²+ y²) = r²

Factorizing this equation, we get:

(1 + k²)* (x² + y²) = r²

Therefore,

x² y² = (x² + y²)² - 2x² y²

We can then substitute this value into the previous equation to get:

x² + y² + k²*(x² + y²) = r²

(1 + k²)* (x² + y²) = r² + 2x² y²

Taking the square root of both sides, we get:

Therefore, √(x² y²) = √[(r² + 2x² y²)/(1 + k²)], This gives us the value of √(x² y²) for the part of the sphere that lies above the cone in the first octant.

one eight-ounce glass of apple juice and one eight-ounce glass of orange juice contain a total of 181.5 milligrams of vitamin c. two eight-ounce glasses of apple juice and four eight-ounce glasses of orange juice contain a total of 538.6 milligrams of vitamin c. how much vitamin c is in an eight-ounce glass of each type of juice? apple juice mg orange juice mg

Answers

The answer is that an eight-ounce glass of apple juice contains 54.5 milligrams of vitamin C, and an eight-ounce glass of orange juice contains 67 milligrams of vitamin C.



Let's use algebra to solve this problem.

First, let's define two variables:

- Let's call the amount of vitamin C in one eight-ounce glass of apple juice "a".
- Let's call the amount of vitamin C in one eight-ounce glass of orange juice "o".

Using this notation, we can translate the information given in the problem into two equations:

- Equation 1: a + o = 181.5 (since one glass of apple juice and one glass of orange juice contain a total of 181.5 milligrams of vitamin C)
- Equation 2: 2a + 4o = 538.6 (since two glasses of apple juice and four glasses of orange juice contain a total of 538.6 milligrams of vitamin C)

Now we can solve this system of equations to find the values of "a" and "o".

One way to do this is to use the first equation to express one variable in terms of the other. For example, we could solve for "a" by subtracting "o" from both sides of Equation 1:

a = 181.5 - o

Then we could substitute this expression for "a" into Equation 2, and solve for "o":

2(181.5 - o) + 4o = 538.6

363 - 2o + 4o = 538.6

2o = 175.6

o = 87.8

Now that we know that one eight-ounce glass of orange juice contains 87.8 milligrams of vitamin C, we can use Equation 1 to find the amount of vitamin C in one glass of apple juice:

a + 87.8 = 181.5

a = 93.7

Therefore, an eight-ounce glass of apple juice contains 93.7 milligrams of vitamin C, and an eight-ounce glass of orange juice contains 87.8 milligrams of vitamin C.

Use the given transformation to evaluate the integral. Double integral x^2da, where is the region bounded by the ellipse 9x^2 4y^2=36; x=2u, y=3v

Answers

The value of the double integral of x² over the region bounded by the ellipse 9x² + 4y² = 36 using the given transformation is π/4.

First, let's define the given transformation. We are given that x=2u and y=3v, which means that we are transforming our original x-y plane into a u-v plane.

We know that the region is bounded by the ellipse 9x² + 4y² = 36. Substituting the given transformations into this equation, we get:

9(2u)² + 4(3v)² = 36 36u² + 36v² = 36 u² + v² = 1

Now, we can use the transformation formula to evaluate the double integral of x² over this region. The transformation formula tells us that:

∬R f(x,y) dA = ∬S f(u,v) |J| dA

where R is the region in the x-y plane, S is the region in the u-v plane, f(x,y) is the integrand in the x-y plane, f(u,v) is the integrand in the u-v plane, |J| is the Jacobian determinant of the transformation (which we will find shortly), and dA is the area element in the respective planes.

In our case, f(x,y) = x² and f(u,v) = (2u)² = 4u². The area element dA in the x-y plane is dx dy, while in the u-v plane it is |6| du dv (since |J| = |d(x,y)/d(u,v)| = |6|). Thus, our integral becomes:

∬R x² dA = ∬S (4u²) (|6|) du dv

Integrating this expression over the limits -1 to 1 for both u and v, we get:

∬S (4u²) (|6|) du dv = 48 ∫∫S u² du dv

where S is the unit circle in the u-v plane. To evaluate the double integral ∫∫S u² du dv, we can use polar coordinates, where u = r cos θ and v = r sin θ. Then, the integral becomes:

[tex]\int _{\theta =0} ^{2\pi} \int_{r=0} ^{ 1}[/tex] (r² cos² θ) r dr dθ

Evaluating this integral using standard techniques, we get:

[tex]\int _{\theta =0} ^{2\pi} \int_{r=0} ^{ 1}[/tex] (r³ cos² θ) dr dθ

[tex]\int _{\theta =0} ^{2\pi} \int_{r=0} ^{ 1}[/tex] (cos² θ)/4 dθ

Simplifying this expression, we get:

[tex]\int _{\theta =0} ^{2\pi}[/tex] (cos² θ)/4 dθ = ∫θ=0 to 2π (1 + cos 2θ)/8 dθ

Using the fact that ∫ cos 2θ dθ = 0 and ∫ dθ = 2π, we get:

[tex]\int _{\theta =0} ^{2\pi}[/tex] (cos² θ)/4 dθ = (1/8) [tex]\int _{\theta =0} ^{2\pi}[/tex]dθ + (1/8) [tex]\int _{\theta =0} ^{2\pi}[/tex] cos 2θ dθ

Simplifying further, we get:

[tex]\int _{\theta =0} ^{2\pi}[/tex](cos² θ)/4 dθ = π/4
