One possible solution for the system of inequalities is given as follows:

13 dimes and 2 nickels.

The first step in obtaining the system of inequalities is identifying the variables, which are given as follows:

Tallulah has at most 18 coins, hence:

x + y ≤ 18.

A nickel is worth 5 cents = $0.05, while a dime is worth 10 cents = $0.1, and Tallulah has at least $1.20 combined, hence:

0.1x + 0.05y ≥ 1.20.

The solution is given by the shaded region on the image given at the end of the answer, and one possible solution is given as follows:

x = 13, y = 2.

Which means that she has 13 dimes and 2 nickels.

I'm going to state what I think that the functions were and then answer:

a. \(f(x)=5x^4\) is not exponential.  The variable is not an exponent.

b. \(g(x)=5(17)^x\) IS.  The variable IS an exponent.

c. \(h(x) =11x\) is not.  But if you meant \(h(x)=11^x\) then it is.  Is the variable an exponent?  If so, then the answer is yes.

d. \(j(x)=6(2.56)^x\) IS, assuming again that the variable is an exponent.

e \(k(x) = 4(6)^x\) IS, assuming again that the variable is an exponent.

Now, if any of the x's I wrote as exponents are not exponents, then those are not exponential functions.

Answer:

[x-(-x)] / 2

Step by step explanation:

Take the number as x.

Its opposite is (-x).

Difference would be:- [x-(-x)]

Half means divided by two, so:- [x-(-x)] / 2

Simplification:-

[x-(-x)] / 2

(x+x) / 2

2x / 2

You can take either the actual answer or the simplified form.

Answer:

x = 50°

Step-by-step explanation:

130 and x are adjacent angles on a straight line and sum to 180° , so

x + 130° = 180° ( subtract 130° from both sides )

x = 50°

The confidence interval for the proportion of orders shipped late is 2.763 and 2.523

We are to going to construct a 95% confidence interval, so here the value is x, divided by n.

That is 120 divided by 1000

120/1000= 0.12

Capital value = 1 - 0.12

                      = 0.88

So definitely we are going to right here for this confidence interval must be written as on.

Confidence interval must be written as a cap plus minus go alpha by 2 multiplied by under root of 0.12 multiplied by 0.88 and this must be divisible by n, which is 1000 points.

So if I write here for this, this is 0.12 plus minus

x = 0.12

n = 1000

s = 0.88 = 0.8

z = 95 = 99

Formula to calculate the confidence interval

CI = x ± zs/ √n

    =0.12 ± 95 × 0.88/√1000

    = 0.12 ± 2.643

     = 2.763 and 2.523

Therefore the confidence interval is 2.763 and 2.523.

Option a, adjacency matrix. An adjacency matrix is a two-dimensional array that represents a graph's edges, where the rows and columns correspond to the vertices of the graph. If there is an edge between two vertices, the corresponding element in the matrix is set to 1, otherwise it is set to 0. This implementation is useful for dense graphs, where the number of edges is close to the maximum possible number of edges.

An adjacency matrix is a simple and efficient way to represent graphs that have a large number of vertices and edges. It allows for fast lookups of the existence of an edge and is useful for various algorithms that require graph representation. However, it is not suitable for sparse graphs, where the number of edges is much smaller than the maximum possible number of edges. In such cases, an adjacency list would be more appropriate.

The common implementation of a graph that uses a two-dimensional array to represent the graph's edges is called an adjacency matrix.

Step-by-step explanation:

The rate of change of y with respect to x is given by dy/dx = xy - (3/2)x²y.

To find the rate of change of y with respect to x, we need to differentiate the given equation. The rate of change can be determined by taking the derivative of both sides of the equation with respect to x.

First, let's differentiate each term separately using the rules of differentiation.

Differentiating x²y with respect to x gives us 2xy using the product rule.

To differentiate 5, we know that a constant has a derivative of 0.

Differentiating 2ln(y) with respect to x requires the chain rule. The derivative of ln(y) with respect to y is 1/y, and then we multiply by dy/dx. So, the derivative of 2ln(y) is 2/y * dy/dx.

Differentiating x³ gives us 3x² using the power rule.

Now, we can rewrite the equation with its derivatives:

2xy - 2/y * dy/dx = 3x²

To solve for dy/dx, we can isolate it on one side of the equation. Rearranging the equation, we get:

2xy = 2/y * dy/dx + 3x²

To isolate dy/dx, we move the term 2/y * dy/dx to the other side:

2xy - 2/y * dy/dx = 3x²

2xy = 2/y * dy/dx + 3x²

2/y * dy/dx = 2xy - 3x²

Now, we can solve for dy/dx by multiplying both sides by y/2:

dy/dx = (2xy - 3x²) * (y/2)

Simplifying further, we have:

dy/dx = xy - (3/2)x²y

Step-by-step explanation:

Measure of arc AB is 360 - (101+97+69) = 360 - 267 = 93 degrees.

Measure of arc DAB is 97+93 = 190 degrees, so measure of angle C is 190/2 =  95 degrees.

The function g(x) is a horizontal dilation of scale factor k = 5/2 of function f(x).

We know that f(x) is a linear function:

f(x) = 2x + 4

Here we know that:

g(x) = 2*(0.4x) + 4

Notice that function g(x) can be written as:

g(x) = f(0.4*x)

So we have a horizontal dilation, remember a horizontal dilation of scale factor k can be written as:

g(x) =f(x/k)

Notice that 0.4 = 2/5

Then we have a horizontal dilation of scale factor 5/2.

The x and y intercepts of a line are when \(y=0\) and \(x=0\) respectively.

The given equation is:

\(\frac xc + \frac yd = 1\)

(1) Why c and d are the intercepts

We have:

\(\frac xc + \frac yd = 1\)

Multiply through by cd

\(cd \times \frac xc + cd \times \frac yd = cd \times1\)

\(dx + cy = cd\)

A linear equation is represented as:

\(Ax + By = C\)

Where:

\(\frac CA \to\) x intercept

\(\frac BA \to\) y intercept

So, by comparing \(Ax + By = C\) to \(dx + cy = cd\)

\(\frac CA \to d \to\) The x-intercept

\(\frac CB \to c \to\) The y-intercept

(b) How the intercepts are related to c and d?

In (a) above, we have:

\(\frac CA \to d \to\) The x-intercept

\(\frac CB \to c \to\) The y-intercept

When \(x = 0\)

We have:

\(dx + cy = cd\)

\(d \times 0 + cy = cd\)

\(cy = cd\)

Divide by c

\(y = d\) ---- the y-intercept

When \(y = 0\)

Step-by-step explanation:

A diagonal matrix can only be orthogonal if all of its diagonal entries are either 1 or -1.

For a matrix to be orthogonal, it must satisfy the condition that its transpose is equal to its inverse. For a diagonal matrix, the transpose is simply the matrix itself, since all off-diagonal entries are zero. Therefore, for a diagonal matrix to be orthogonal, its inverse must also be equal to itself. This means that the diagonal entries must be either 1 or -1, since those are the only values that are their own inverses. Any other diagonal entry would result in a different value when its inverse is taken, and thus the matrix would not be orthogonal. It's worth noting that not all diagonal matrices are orthogonal. For example, a diagonal matrix with all positive diagonal entries would not be orthogonal, since its inverse would have different diagonal entries. The only way for a diagonal matrix to be orthogonal is if all of its diagonal entries are either 1 or -1.

The expression that represents the profit Justin made is 1.31c + 1.66m + 1.6b ( option C)

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power. In other words, none of the exponents can be greater than 1. For example, x² is a variable raised to the second power, but x is a variable raised to the first power.

Justin earned $1.50c selling cookies but he spent $0.19c. Therefore the profit on cookies = $(1.5-0.19)c. = $1.31c

He earned $2.25m by selling muffins and spent $0.59m on the ingredients. Therefore the profit He made on muffins = $(2.25-0.59) = $1.66m

He earned $1.90b selling brownies and he spent $0.30b on ingredients. The profit he made on brownies = $1.90-$0.30 = $1.60b

The value of the copier after 3 years and 6 months can be found by substituting t = 3.5 into the function and solving for V. The salvage value of the copier can be found by substituting t = 5 into the function and solving for V.

After 3 years and 6 months of use, the copier is worth $5,800. This can be found by substituting t = 3.5 into the function V(t)-3600t+20000: V(3.5) = 3600(3.5) - 20000 + 20000 = $5,800.

The salvage value of the copier after 5 years of use is $4,000. This can be found by substituting t = 5 into the function V(t)-3600t+20000: V(5) = 3600(5) - 20000 + 20000 = $4,000. This is the value of the copier when it is sold or replaced after 5 years of use.

The domain of the function is all real numbers because time and value can take on any real value. However, since the function is only defined for the first 5 years of use, t must be between 0 and 5.

The graph of the function is a downward-sloping line with an intercept of $20,000 on the y-axis and a slope of -3600. This means that the value of the copier decreases by $3,600 each year. At t = 0, the copier is worth $20,000, and after 5 years, it is worth $4,000. The graph is a straight line because the function is linear.
