Answer:18.84

Step-by-step explanation:

c = 2pi(r)

C = 2pi(6/2). Since r = d/2

C = 18.84

The number of nonnegative integer solutions to the inequality x1 + x2 + x3 ≤ 11 is C(14,3) = 364.

We can solve this inequality by introducing an auxiliary variable x4, such that x1 + x2 + x3 + x4 = 11. Here, x1, x2, x3, and x4 are all nonnegative integers.

We can interpret this equation as follows: imagine we have 11 identical objects and we want to distribute them among four boxes (x1, x2, x3, and x4). Each box can contain any number of objects, including zero. The number of solutions to this equation will give us the number of nonnegative integer solutions to the original inequality.

We can use a technique known as stars and bars to count the number of solutions to this equation. Imagine we represent the 11 objects as stars: ***********.

We can then place three bars to divide the stars into four groups, each group representing one of the variables x1, x2, x3, and x4. For example, if we place the first bar after the first star, the second bar after the third star, and the third bar after the fifth star, we get the following arrangement:

| ** | * | ****

This arrangement corresponds to the solution x1=1, x2=2, x3=1, and x4=7. Notice that the number of stars to the left of the first bar gives the value of x1, the number of stars between the first and second bars gives the value of x2, and so on.

We can place the bars in any order, so we need to count the number of ways to arrange three bars among 14 positions (11 stars and 3 bars). This is equivalent to choosing 3 positions out of 14 to place the bars, which can be done in C(14,3) ways.

Therefore, the number of nonnegative integer solutions to the inequality x1 + x2 + x3 ≤ 11 is C(14,3) = 364.

Answer:

Rita: r - 5= 2c, or r - 5= 2(36), or r - 5 = 72

Cora: (r - 5)/2 = 36

Step-by-step explanation:

The quotient of two integers can be positive, negative, or zero depending on the signs of the dividend and divisor.

When dividing two integers, the quotient can be positive, negative, or zero. The sign of the quotient depends on the signs of the dividend and the divisor. If both the dividend and divisor have the same sign (both positive or both negative), the quotient will be positive.

If they have opposite signs, the quotient will be negative. If the dividend is zero, the quotient is zero regardless of the divisor.

For example, when we divide 12 by 4, we get a quotient of 3, which is positive because both 12 and 4 are positive integers. However, when we divide -12 by 4, we get a quotient of -3, which is negative because the dividend (-12) is negative and the divisor (4) is positive.

Finally, if we divide 0 by any integer, the quotient is always 0.

Therefore, the quotient of two integers can be positive, negative, or zero depending on the signs of the dividend and divisor.

The system of equations with no solutions is the second one:

3x - 7y = 22

4.5x - 10.5y = 44

When we have a system of linear equations, the only case where the system has no solutions is when both of the lines are parallel lines (thus, the lines never intercept).

So we need to identify the system of linear equations where the lines are parallel.

If you look at the second system of equations, we have:

3x - 7y = 22

4.5x - 10.5y = 44

We can multiply the first equation by 1.5 to get:

1.5*(3x - 7y) = 1.5*22

4.5x - 10.5y = 33

Then the system is:

4.5x - 10.5y = 33

4.5x - 10.5y = 44

We can see that these lines are parallel,and thus, this system has no solutions.

The required rate-of-change function is given as

df(x)/dx=(-9x2+4x-7)(0.5)-9x(2x-1).

a. The product function is given as f(x)=(-9x2+4x−7)((0.5)/(x2)−2x0.5)

Let us first simplify the second function f(x)=(0.5x−2)/x2−2√x

Now, multiply the first and second functions

f(x)=(-9x2+4x−7)(0.5x−2)/x2−2√x

Now, we get the common denominator

f(x)=(-9x2+4x−7)(0.5x−2)/(x2-2x√x+2x√x-x)

Cancelling the terms we get f(x)=(-9x2+4x−7)(0.5x−2)/(x2-x)

Factorizing the denominator we get f(x)=(-9x2+4x−7)(0.5x−2)/(x(x-1))

Thus, the required product function is given as f(x)=(-9x2+4x−7)(0.5x−2)/(x(x-1))

b. We know that the rate of change of a function y with respect to x is given by the derivative dy/dx.

Thus, we need to find the derivative of the function f(x) with respect to x.

Using the product rule, the derivative of f(x) is given as

df(x)/dx=(-9x2+4x-7)

(d/dx)(0.5x-2)+(d/dx)(-9x2+4x-7)(0.5x-2)

Differentiating the first term we get,

df(x)/dx=(-9x2+4x-7)(0.5)+(d/dx)(-9x2+4x-7)(0.5x-2)

Differentiating the second term we get,

df(x)/dx=(-9x2+4x-7)(0.5)+(-18x+4)(0.5x-2)

df(x)/dx=(-9x2+4x-7)(0.5)-9x(2x-1)

Hence, the required rate-of-change function is given as

df(x)/dx=(-9x2+4x-7)(0.5)-9x(2x-1).

The answer of the given question based on the function is ,  the domain of f(g(x)) is all real numbers except x = 1.

A function, in mathematics, is a relationship or mapping between a set of inputs, called the domain, and a set of outputs, called the codomain or range. It assigns a unique output value to each input value.

Functions are often denoted by a symbol, such as f, and written as f(x), where x represents the input variable.

Here are some key aspects of functions:

Domain: The domain of a function is the set of all possible input values for which the function is defined. It specifies the valid inputs for the function.

Codomain/Range: The codomain or range of a function is the set of all possible output values that the function can produce.

Function Notation: Functions are typically represented using functional notation, such as f(x), where the function name (f) is followed by the input variable (x).

Mapping: A function can be seen as a mapping that relates each input value to a unique output value.

It describes how elements of the domain are transformed or associated with elements of the range.

To find the domain of the composition f(g(x)), we need to consider the domains of both f(x) and g(x).

The function f(x) = (x - 9) / (1) is defined for all real numbers except x = 1, since division by zero is undefined.

The function g(x) = (x⁴ + 5) after performing the given transformations: shift upward 10 units and shift 83 units to the right can be written as g(x) = (x - 83)⁴ + 15.

Now, we need to find the domain of f(g(x)). Since both f(x) and g(x) are defined for all real numbers except x = 1, the domain of the composition f(g(x)) is also all real numbers except x = 1.

Therefore, the domain of f(g(x)) is all real numbers except x = 1.

The expression for the power delivered to a resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

According to the given information, the power delivered to a resistance R when an alternating current of frequency f and peak current I_0 passes through it is represented by the equation P = I^2_0 R sin^2 2 pi ft.

To express this equation in terms of csc^2 2 pi ft, we can use the trigonometric identity csc^2 x = 1/sin^2 x. Substituting this identity into the equation, we get P = I^2_0 R (1/sin^2 2 pi ft).

Since csc^2 x is the reciprocal of sin^2 x, we can rewrite the equation as P = I^2_0 R (csc^2 2 pi ft). This expression represents the power delivered to the resistance in terms of csc^2 2 pi ft.

Therefore, the correct expression for the power delivered to the resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

When mixing Ba(NO3)2 (aq) and Cu(NO3)2 (aq) solutions, the resulting solution is expected to have a light blue color due to the formation of a precipitate called barium copper nitrate.

Barium copper nitrate is a light blue solid that forms when barium ions (Ba2+) from Ba(NO3)2 react with copper ions (Cu2+) from Cu(NO3)2.

Upon mixing the two solutions, the following reaction takes place:

Ba(NO3)2 (aq) + Cu(NO3)2 (aq) → BaCu(NO3)4 (s)

The formation of the light blue barium copper nitrate precipitate gives the solution its characteristic color. It is important to note that the intensity of the color may depend on the concentration of the solutions used and the amount of precipitate formed.

It is worth mentioning that handling and mixing chemicals should be done with caution and proper laboratory procedures. Additionally, if you are performing a specific experiment or working in a laboratory, it is always recommended to refer to the appropriate literature or consult with a qualified professional for precise information regarding reactions and their outcomes.

A parabola is a type of graph, or curve, that is represented by an equation of the form y = ax² + bx + c. The vertex of a parabola is the point where the curve reaches its maximum or minimum point, depending on the direction of the opening of the parabola. In this case, the vertex of the parabola is at (-4,-1).
To find the equation of the parabola, we need to know two more points on the graph. We are given that when the y-value is 0, the x-value is 10-D. We can use this information to find another point on the graph.
When the y-value is 0, we have:
0 = a(10-D)² + b(10-D) + c
Simplifying this equation gives:
0 = 100a - 20aD + aD² + 10b - bD + c
Since the vertex is at (-4,-1), we know that:
-1 = a(-4)² + b(-4) + c
Simplifying this equation gives:
-1 = 16a - 4b + c
We now have two equations with three unknowns (a,b,c). To solve for these variables, we need one more point on the graph. Let's use the point (0,-5) as our third point.
When x = 0, y = -5:
-5 = a(0)² + b(0) + c
Simplifying this equation gives:
-5 = c
We can now substitute this value for c into the other two equations to get:
0 = 100a - 20aD + aD² + 10b - bD - 5
-1 = 16a - 4b - 5
Simplifying these equations gives:
100a - 20aD + aD² + 10b - bD = 5
16a - 4b = 4
We now have two equations with two unknowns (a,b). We can solve for these variables by using substitution or elimination. For example, we can solve for b in the second equation and substitute it into the first equation:
16a - 4b = 4
b = 4a - 1
100a - 20aD + aD² + 10(4a-1) - D(4a-1) = 5
Simplifying this equation gives:
aD² - 20aD - 391a + 391 = 0
We can now use the quadratic formula to solve for D:

D = [20 ± sqrt(20² - 4(a)(391a-391))]/2a
D = [20 ± sqrt(400 - 1564a² + 1564a)]/2a
D = 10 ± sqrt(100 - 391a² + 391a)/a
There are two possible values for D, depending on the value of a. However, since we don't have any information about the sign of a, we cannot determine which value of D is correct. Therefore, the final equation of the parabola is:
y = ax² + bx - 5
