According to the given rectangle, approximately 112.27 feet of fence are required to enclose the rose garden.
The perimeter of a rectangle is the sum of all its sides. In this case, the rectangle has two sides of length 24 feet and two sides of length 18 feet.
Therefore, the perimeter of the rectangle can be calculated as follows:
Perimeter of rectangle = 2 * (Length + Width)
= 2 * (24 ft + 18 ft) = 2 * 42 ft = 84 ft.
The circumference of a circle can be calculated using the formula:
Circumference = π * Diameter.
Diameter of the Semicircle: The diameter of the semicircle is equal to the width of the rectangle, which is 18 feet.
Circumference of the Semicircle: Using the formula mentioned above:
Circumference = π * 18 ft
≈ 56.5487 ft (rounded to four decimal places).
Perimeter of the Semicircle: As it is a semicircle, we only need half of the circumference:
Perimeter of semicircle = Circumference / 2
≈ 56.5487 ft / 2 ≈ 28.2744 ft (rounded to four decimal places).
Total Fence Length Required: Now, we add the perimeter of the rectangle and the semicircle to find the total length of fence required to enclose the rose garden:
Total fence length = Perimeter of rectangle + Perimeter of semicircle
= 84 ft + 28.2744 ft ≈ 112.2744 ft (rounded to four decimal places).

PLEASE HELP!!! What is the product in simplest form? State any restrictions on the variable. z^2/z+1 times z^2+3z+2/z^2+3z
Hence, the product is:
[tex]\dfrac{z(z+2)}{z+3}[/tex] such that: z≠ -1,0 and -3.
Step-by-step explanation:We are asked to represent the product in the simplest form along with the restrictions applied to z.
We have to evaluate the expression:
[tex]\dfrac{z^2}{z+1}\times \dfrac{z^2+3z+2}{z^2+3z}\\\\=\dfrac{z^2}{z+1}\times \dfrac{z^2+3z+2}{z(z+3)}[/tex]
Hence,
z≠ -1,0 and -3.
Since, otherwise the denominator will be equal to zero and hence the product will not be defined.
Now, we know that:
[tex]z^2+3z+2=z^2+2z+z+2\\\\z^2+3z+2=z(z+2)+1(z+2)\\\\z^2+3z+2=(z+1)(z+2)[/tex]
Hence,
[tex]\dfrac{z^2}{z+1}\times \dfrac{z^2+3z+2}{z^2+3z}=\dfrac{z^2}{z+1}\times \dfrac{(z+1)(z+2)}{z(z+3)}\\\\=\dfrac{z(z+2)}{z+3}[/tex]
( since z and (z+1) term is cancelled as it was same in numerator and denominator)
Hence, the product is:

What is the smallest positive integer with exactly 14 positive divisors?
The smallest positive integer with exactly 14 positive divisors is 24. The number is found by considering its prime factorization and adding 1 to each exponent, then multiplying the results together. Another prime factor raised to the power of 5 can be included to have exactly 14 divisors.
Explanation:The smallest positive integer with exactly 14 positive divisors is 24.
To find this, we need to consider the prime factorization of the number. Let's express 24 as a product of prime factors: 24 = 2^3 * 3^1.
The number of divisors is found by adding 1 to each exponent in the prime factorization and multiplying them together: (3+1)(1+1) = 4 * 2 = 8. However, we need exactly 14 divisors, so we can multiply 24 by another prime factor raised to the power of 5: 24 * 5^4 = 24 * 625 = 15,000.

The smallest positive integer with exactly 14 positive divisors is 192. We derived this by using the prime factorization method and finding suitable combinations to get exactly 14 divisors.
To find the smallest positive integer with exactly 14 positive divisors, we need to understand the number of divisors formula. For an integer n = p1e* p2e² * ... * p^ke^k, the number of divisors is given by (e1 + 1)(e² + 1) ... (e^k + 1).
To have exactly 14 divisors, we need (e1 + 1)(e² + 1) ... (e^k + 1) = 14. The factorizations of 14 are 14 = 14 * 1, 7 * 2, or 2 * 7. Let's use the smallest primes to minimize our number:
14 = 14 * 1: This means n = p113. Using the smallest prime number, we have n = 213 = 8192, which is too large.
14 = 7 * 2: This means n = p16 * p21. Using the smallest primes, we get n = 26 * 3 = 64 * 3 = 192.
14 = 2 * 7: This means n = p11 * p26. Using the smallest primes, we get n = 2 * 36 = 2 * 729 = 1458.
Comparing these solutions, the smallest positive integer is n = 192, which has exactly 14 positive divisors.

A spinner is divided into 4 equal sections the probability of landing on A is 1/4 Norma spins the spinner 16 times how many times can she expect the spinner to land on A
Final answer:
Norma can expect the spinner to land on section A 4 times after spinning it 16 times, based on the probability of [tex]\frac{1}{4}[/tex].
Explanation:
The question asks about the expected number of times Norma can anticipate the spinner to land on section A after spinning it 16 times, given that the probability of landing on A is [tex]\frac{1}{4}[/tex]. To find this, we use the concept of expected value, which in this context is the probability of an event happening multiplied by the number of trials. Since the probability of landing on A is [tex]\frac{1}{4}[/tex] and there are 16 spins, the expected number of times landing on A is calculated as [tex]\frac{1}{4}[/tex] multiplied by 16.
Expected number of landings on A = Probability of landing on A × Number of spins = [tex]\frac{1}{4}[/tex] × 16 = 4.
Therefore, Norma can expect the spinner to land on section A four times after spinning it 16 times.
What is the probability of drawing a red card, not replacing it, and then drawing another red card? there are 2 red cards and 3 blue cards
Let's analyse both scenarios: for the first pick, you have 5 cards in total, of which 2 are red. So, you have a chance of 2/5 of picking a red card.
Now, assume you picked a red card with the first pick. The new scenario will be different, now there are only 4 cards in total (since you didn't replace the first picked card), of which only 1 is red. This means that you have a chanche of 1/4 of picking a red card.
Once you figured the probabilities of both events, if you want to compute the probability of the two events happening one after the other, you simply have to multiply them, so you have

Step-by-step explanation:
The length of a rectangle is 6 m longer than its width. if the perimeter of the rectangle is 48 m , find its area.
Answer:
135m²
Step-by-step explanation:
Perimeter = 2(l + w)
l = w + 6
Substituting for l, gives;
2(w+6+w)
48 = 2w + 12 +2w
48 = 4w + 12
48 - 12 = 4w
36 = 4w
w = 9
Since w = 9, then l = w +6
l = 9 + 6
l = 15
Area = l * w
Area = 15 * 9
Area = 135m²
What are the roots of the equation? 5 x 3+45x2+70x=0
Final answer:
The roots of the equation 5x³ + 45x² + 70x = 0 are -7 and -2.
Explanation:
This expression is a quadratic equation of the form at² + bt + c = 0, where the constants are a = 5, b = 45, and c = 70. To find the roots of the equation, we can use the quadratic formula:
x = (-b ± √(b² - 4ac)) / (2a)
Plugging in the values, we get:
x = (-45 ± √(45² - 4(5)(70))) / (2(5))
Simplifying further gives us:
x = (-45 ± √(2025 - 1400)) / 10
And finally, calculating the square root and applying the ± gives us the two roots:
x = (-45 ± √625) / 10
x = (-45 ± 25) / 10
which can be further simplified to:
x = -7 or x = -2

Final answer:
Cohen's d for the given sample is 0.3, calculated by subtracting the population mean from the sample mean and dividing by the population standard deviation.
Explanation:
The student's question is regarding the calculation of Cohen's d for a sample after treatment. Cohen's d is a measure of effect size used to indicate the standardized difference between two means. In this case, the following formula can be used: Cohen's d = (M - μ) / σ, where M is the sample mean after treatment, μ is the population mean, and σ is the population standard deviation.
Given that M = 63, μ = 60, and σ = 10, the calculation of Cohen's d is as follows:
Cohen's d = (63 - 60) / 10 = 3 / 10 = 0.3.
Therefore, the value of Cohen's d for this sample is 0.3, which is considered a small effect size according to Cohen's standards.
A company makes computer chips from square wafers of silicon. It wants to keep the side length of a wafer very close to 12 mm and it wants to know how the area A(x) of a wafer changes when the side length x changes. Find A'(12)

Final answer:
To find A'(12), the rate at which the area A(x) changes when the side length x changes, take the derivative of A(x), which is 2x, and evaluate it at x = 12. The derivative of A(x) is 2x, so A'(12) = 2(12) = 24.
Explanation:
To find the rate at which the area A(x) changes with respect to a change in x, we need to take the derivative of A(x) with respect to x. In this case, A(x) represents the area of a square wafer of silicon with a side length x. The derivative with respect to x is A'(x), which represents the rate of change of the area.
We want to find A'(12), which means we want to find the rate of change of the area when the side length is 12 mm. To do this, we need to take the derivative of A(x) and then evaluate it at x = 12.
Since the side length of the wafer is very close to 12 mm, we can assume x = 12.
Let's find the derivative of A(x):
A(x) = x^2
A'(x) = 2x
Now we can evaluate A'(12):
A'(12) = 2(12) = 24

A company makes storage tanks in the shape of a cylinder of height H and radius R. The standard model the company sells has a height of 20 cm in the radius of 20 cm. Customers may also request tanks that have a smaller radius. For each centimeter a tank’s radius decreases, however it’s height must increase by 5 cm.
The volume of a cylinder Jeckel storage tank is represented by the formula V= 3.14 (radius)^2 (height). X represent the number of centimeters by which the radius is decreased due to a customer’s request. Write a function V(x) to represent the volume of a tank a customer a request as a function of X.
We are given the formula for volume V:
V = 3.14 r^2 h
where r is radius and h is height
The standard height and radius is both 20 cm each, therefore we can write it as:
V = 3.14 (20)^2 (20)
It is stated that the radius can be modified, for every 1 cm change in tanks radius, the height must increase by 5 cm, therefore:
V = 3.14 (20 – x)^2 (20 + 5x)
or in general form:
V = 3.14 (r – x)^2 (h + 5x)

•a cylinder with a base radius of 14cm
If a rectangle is rotated about the line b, then the three-dimensional figure formed is cylinder with a circle base.
One side of the rectangle has lenght of 24 cm. Let the second side has length of x cm. The perimeter of the rectangle is 76 cm, then
24 + x + 24 + x = 76,
2x + 48 = 76,
2x= 76 - 48,
2x= 28,
x = 14 cm.
Then the three-dimensional figure is a cylinder with a base radius of 14 cm.
Answer: correct choice is D
Answer: •a cylinder with a base radius of 14cm
Step-by-step explanation:
From the given picture it can be seen that the side of rectangle is adjacent to line B is the longer side.
If the rectangle is rotated about line b, then it will create a cylinder such that
the radius of the cylinder= smaller(width) side of the rectangle
The measure of the longer side (length) of rectangle= 24 cm
Perimeter of rectangle=[tex]2[length+width][/tex]
[tex]\\\Rightarrow\ 76=2[24+w]\\\Rightarrow\ 24+w=38\\\Rightarrow\ w=14[/tex]
hence, the measure of smaller side is 14 cm.
Therefore, the base radius =14 cm
