Must click thanks and mark brainliest
If each link is made of thin silver wire and is in the shape of a circle of radius 2.5 cm, the value of the silver chain is $94.20.
To find the value of the silver chain, we need to calculate the total length of the silver wire used in making the chain and then multiply it by the cost per centimeter.
Each link in the chain is a circle with a radius of 2.5 cm. The circumference of a circle can be calculated using the formula 2πr, where r is the radius.
In this case, the circumference of each link is:
Circumference = 2 * 3.14 * 2.5 cm = 15.7 cm
Since there are 100 links in the chain, we multiply the circumference of each link by 100 to get the total length of the silver wire used:
Total length = 15.7 cm/link * 100 links = 1570 cm
Now, we can calculate the value of the chain by multiplying the total length of the silver wire by the cost per centimeter:
Value of the chain = 1570 cm * $0.06/cm = $94.20

The derivatives of the data is f'(x) = 8x - 3x^2 f''(x) = 8 - 6x f'''(x) = -6 f^(4)(x) = 0
To find the derivative of f(x), denoted as f'(x), we differentiate each term of the function with respect to x using the power rule. The derivative of 4x^2 is 8x, and the derivative of -x^3 is -3x^2. Therefore, f'(x) = 8x - 3x^2.
To find the second derivative, f''(x), we differentiate f'(x) with respect to x. The derivative of 8x is 8, and the derivative of -3x^2 is -6x. Thus, f''(x) = 8 - 6x.
To find the third derivative, f'''(x), we differentiate f''(x) with respect to x. The derivative of 8 is 0, and the derivative of -6x is -6. Therefore, f'''(x) = -6.
Finally, to find the fourth derivative, denoted as f^(4)(x), we differentiate f'''(x) with respect to x. The derivative of -6 is 0, yielding f^(4)(x) = 0.
Hence, f'(x) = 8x - 3x^2, f''(x) = 8 - 6x, f'''(x) = -6, and f^(4)(x) = 0.

2. Solve the following difference equations: (a) \( x_{t+1}=\frac{1}{2} x_{t}+3 \) (b) \( x_{t+1}=-3 x_{t}+4 \)
Answers
(a) ( x_{t+1}=\frac{1}{2} x_{t}+3 ), the solution to this difference equation is x_t = 2^t + 3, The difference equations in this problem are both linear difference equations with constant coefficients.
This can be found by solving the equation recursively. For example, the first few terms of the solution are
t | x_t
--- | ---
0 | 3
1 | 7
2 | 15
3 | 31
The general term of the solution can be found by noting that
x_{t+1} = \frac{1}{2} x_t + 3 = \frac{1}{2} (2^t + 3) + 3 = 2^t + 3
(b) ( x_{t+1}=-3 x_{t}+4 )
The solution to this difference equation is
x_t = 4 \cdot \left( \frac{1}{3} \right)^t + 4
This can be found by solving the equation recursively. For example, the first few terms of the solution are
t | x_t
--- | ---
0 | 4
1 | 5
2 | 2
3 | 1
The general term of the solution can be found by noting that
x_{t+1} = -3 x_t + 4 = -3 \left( 4 \cdot \left( \frac{1}{3} \right)^t + 4 \right) + 4 = 4 \cdot \left( \frac{1}{3} \right)^t + 4
The difference equations in this problem are both linear difference equations with constant coefficients. This means that they can be solved using a technique called back substitution.
Back substitution involves solving the equation recursively, starting with the last term and working backwards to the first term.
In the first problem, the equation can be solved recursively as follows:
x_{t+1} = \frac{1}{2} x_t + 3
x_t = \frac{1}{2} x_{t-1} + 3
x_{t-1} = \frac{1}{2} x_{t-2} + 3
...
x_0 = \frac{1}{2} x_{-1} + 3
The general term of the solution can be found by noting that
x_{t+1} = \frac{1}{2} x_t + 3 = \frac{1}{2} (2^t + 3) + 3 = 2^t + 3
The second problem can be solved recursively as follows:
x_{t+1} = -3 x_t + 4
x_t = -3 x_{t-1} + 4
x_{t-1} = -3 x_{t-2} + 4
...
x_0 = -3 x_{-1} + 4
The general term of the solution can be found by noting that
x_{t+1} = -3 x_t + 4 = -3 \left( 4 \cdot \left( \frac{1}{3} \right)^t + 4 \right) + 4 = 4 \cdot \left( \frac{1}{3} \right)^t + 4

X is normally distributed random variable with a mean of 5 and a variance of 4. The probability that X is greater than 10.52 is?
Answers
The probability that X is greater than 10.52 is approximately 0.0029.
How to find probability that X is greater than 10.52?We can start by standardizing the normal distribution using the z-score formula:
z = (X - μ) / σ
where X is the random variable, μ is the mean, and σ is the standard deviation. In this case, we have:
X ~ N(5, 4)
μ = 5
σ =\(\sqrt(4)\) = 2
So, the z-score for X = 10.52 is:
z = (10.52 - 5) / 2 = 2.76
We can then use a standard normal distribution table or calculator to find the probability that Z is greater than 2.76.
Using a standard normal distribution table, we find that this probability is approximately 0.0029.
Therefore, the probability that X is greater than 10.52 is approximately 0.0029.

Let f(x)=√x with f:R→R. Discuss the properties of f. Is it injective, surjective, bijective, is it a function? Why or why not? Under what conditions change this?Explain using examples.I'm having some trouble figuring out this equation.
Answers
The function f(x)=√x with f:R→R is injective and surjective but not bijective.
Injective (or one-to-one): f(x) is injective, which means that if f(x1) = f(x2), then x1 = x2. In other words, if the square root of x1 is equal to the square root of x2, then x1 and x2 are equal.
Surjective (or onto): f(x) is surjective, which means that for every y in the codomain (R), there exists an x in the domain (R) such that f(x) = y. In other words, the square root of any real number can always be expressed as a real number.
Bijective: f(x) is not bijective. The square root function is not bijective because it is not defined for negative values of x.
Function: A function f is a function if for every x in the domain of f, there is exactly one y in the codomain of f such that f(x) = y. In other words, each x in the domain is mapped to exactly one y in the codomain.
In the case of f(x) = √x, it is a function. For every x in the domain of f, which is [0,∞), there is exactly one y in the codomain of f, which is [0,∞), such that f(x) = y.

Answers
The profit function P(x) can be obtained by subtracting the cost function C(x) from the revenue function R(x). By substituting the given value x=22 into the profit function, the profit from selling 22 hundred cell phones can be calculated.
(a) To find the profit function P(x), we subtract the cost function C(x) from the revenue function R(x). Using the given functions R(x)=-1.5x^2+339x and C(x)=0.02x^3-2x^2+70x+750, we can write the profit function as P(x) = R(x) - C(x). Substituting the expressions for R(x) and C(x) into the profit function equation, we get P(x) = (-1.5x^2 + 339x) - (0.02x^3 - 2x^2 + 70x + 750). Simplifying further, we combine like terms to obtain P(x) = -0.02x^3 + 3.5x^2 + 269x - 750.
(b) To find the profit when x = 22 hundred cell phones are sold, we substitute x = 22 into the profit function P(x). By calculating P(22), we can determine the profit made from selling 22 hundred cell phones. Substituting x = 22 into the profit function P(x) = -0.02x^3 + 3.5x^2 + 269x - 750, we have P(22) = -0.02(22)^3 + 3.5(22)^2 + 269(22) - 750. Evaluating this expression, we can determine the specific value of the profit.
In summary, the profit function P(x) is obtained by subtracting the cost function C(x) from the revenue function R(x). By substituting the given value x = 22 into the profit function, the profit from selling 22 hundred cell phones can be calculated.

A rectangular prism has a height of a, a width of b, and a length of c. Which equation represents the total surface area of the rectangular prism in units2?
Answers
The volume of the rectangular prism is 105.57
What is the volume of a rectangular prism?
A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.
The volume of a rectangular prism=Length X Width X Height
Where l, h and w represent the length, height and width respectively.
Given that;
Length of the prism is 2 times the width L = 2w
the width is 4 times the height w = 4h
Now let’s plug these values;
the surface area equation, it becomes;
A = 2(2w(w) + w(w/4) + w/4(2w))
A = 2(2w^2 + w^2/4 + w^2/2)
A = 1/2(7w^2)
792 x2 = 7w^2
w = 15.04
The volume of a rectangular prism=Length X Width X Height
V = 2w x w x w/4
V x 2 = w³
V = 15.04³/2
V = 105.57
Thus, the volume is 105.57.

x = -5
b = ?
Our equation is this, we are solving for b
==> -3 = -3/5 ( -5) + b
==> -3 = -3/5 ( -5) + b ( multiply the brackets)
==> -3 = 3 + b ( subtract 3 to both sides)

What is the probability that X equals 2?
Question 3 options:

b) 0. 44
c) 0. 30
d) 0. 56
Answers
The probability that X equals 2 is 0.44.
We have given cumulative distribution function for the discrete random variable X. The probability that X equals 2 can be found by taking the difference between the probability that X is less than or equal to 2 and the probability that X is less than or equal to 1.
P(X = 2) = P(X ≤ 2) - P(X ≤ 1)
Using the cumulative distribution function given in the problem, we find:
P(X ≤ 2) = 0.30 + 0.44 = 0.74
P(X ≤ 1) = 0.30
Therefore,
P(X = 2) = 0.74 - 0.30 = 0.44
So the probability that X equals 2 is 0.44.
