Answer:

Population density = 47 people per square miles

Step-by-step explanation:

From the picture attached,

Coordinates of vertex B → (3.87, 2.76)

Which represents length of vertex A from origin O (AD)= 2.76 units ≈ 276 miles

Length of vertex B from origin O (CD) = 3.87 units ≈ 3.87 miles

Area of rectangle ABCD = Length × Width

                                         = CD × AD

                                         = 387 × 276

                                         = 106812 square miles

Population of Colorado = 5029196 people

Population density of Colorado = \(\frac{\text{Total population}}{\text{Total area}}\)

                                                     = \(\frac{5029196}{106812}\)

                                                     = 47.08

                                                     ≈ 47 people per square miles

The population density at the end of 2010 in people per square mile is 47.

Length of vertex A from origin O (AD)= 2.76 units ≈ 276 miles

Length of vertex B from origin O (CD) = 3.87 units ≈ 3.87 miles

Now  

Area of rectangle ABCD = Length × Width

 = CD × AD

= 387 × 276

= 106812 square miles

And,

Population of Colorado = 5029196 people

So,  the population density is

\(= 5029196 \div 106812\)

= 47

The flow of the velocity field along the straight line path from (0,0) to (1,1) is 55/3.

To find the flow of the velocity field along a path from (0,0) to (1,1), we need to integrate the velocity field along that path.

Let's consider two different paths: a straight line path and a curved path.

Straight Line Path:

For the straight line path from (0,0) to (1,1), we can parameterize the path as x(t) = t and y(t) = t, where t varies from 0 to 1.

The velocity field is given as \(f = 5y^2 \times 9i + (10xy)j.\)

To find the flow along this path, we need to compute the line integral of the velocity field along the path.

The line integral is given by:

Flow = ∫C f · dr,

where C represents the path and dr represents the differential displacement vector along the path.

Plugging in the parameterized values into the velocity field, we have:

\(f = 5(t^2) \times 9i + (10t\times t)j = 45t^2i + 10t^2j.\)

The differential displacement vector,\(dr,\) is given by dr = dx i + dy j.

Since dx = dt and dy = dt along the straight line path, we have dr = dt i + dt j.

Therefore, the line integral becomes:

Flow = ∫\((0 to 1) (45t^2 i + 10t^2 j) . (dt i + dt j)\)

= ∫\((0 to 1) (45t^2 + 10t^2) dt\)

= ∫\((0 to 1) (55t^2) dt\)

= \([55(t^3)/3] (from 0 to 1)\)

= 55/3.

So, the flow of the velocity field along the straight line path from (0,0) to (1,1) is 55/3.

Curved Path:

For a curved path, the specific equation of the path is not provided. Hence, we cannot determine the flow of the velocity field along the curved path without knowing its equation.

Answer:

Domain of the given function is all real numbers i.e. R.

Step-by-step explanation:

It is given that the given graph is a V shaped graph.

It is crossing x - axis at \((-2,0)\)

then y-axis at \((0,-2)\) and

then again x - axis at \((2,0)\).

If we try to plot the graph, the graph will be like it comes down from the negative x axis side and then intersect x axis at \((-2,0)\), then intersects y axis at \((0,-2)\)  and then rises towards the right side (i.e. positive x axis) intersecting the positive x axis at \((2,0)\).

Please find attached graph for the same.

This graph denotes the following function:

\(y=f(x)=|x|-2\)

Domain of a function \(y =f(x)\) is the values of \(x\) that can be provided to the function.

Here function is a modulus function and from graph we can easily infer that it can have any Real Number, R as its input.

Modulus function has R as its domain.

So, the answer is:

Domain of given function is all Real Numbers, R

Answer:

Step-by-step explanation:

y = 3x + 2 → (1)

y = x + 12 → (2)

substitute y = 3x + 2 into (2)

3x + 2 = x + 12 ( subtract x from both sides )

2x + 2 = 12 ( subtract 2 from both sides )

2x = 10 ( divide both sides by 2 )

x = 5

substitute x = 5 into either of the 2 equations and solve for y

substituting into (2)

y = x + 12 = 5 + 12 = 17

solution is (5, 17 )

Step-by-step explanation:

From division algorithm kiki divides total number of rolls by 9, and results 27 with remainder, r= 5, then the right interpretation is kiki has 5 rolls left after filling 27 baskets. So, option(b) is correct one.

The division algorithm tells us that when a number 'a' is divided by a number 'b' the quotient 'q' and the remainder 'r' represented by relation, a = bq + r.

Total number of wheat rolls that kiki had

= 131

Total number of rye rolls that kiki had

= 117

Total number of rolls she had = 131 + 117

= 248

Number of rolls placed by Kiki in one basket = 9

Total number of baskets she needed to place the rolls = dividing total rolls by total number of rolls in one basket, \(= \frac{ 248}{9} \)

Results, quotient =27 and remainder = 5

That means when kiki wants to put all rolls in baskets, we placed total 243 rolls in 27 baskets with 9 rolls in each and 5 rolls are remained. The rammining rolls are represented by remainder. Hence, required interpretation is that 5 rolls are left after placed in 27 baskets .

Based on the context of the problem, the range of the exponential function y = \(45,529(0.78)^x\) is y > 0.

The exponential function for depreciation given in the problem is:

y = 45,529(0.78)^x

This function gives us the value of Sharlene's truck in dollars after x months of ownership, assuming that the depreciation follows a constant rate and is modeled by an exponential function.

To find the range of the function, we need to consider the minimum value that y can take. Since depreciation leads to a decrease in value over time, y should always be greater than zero. In other words, the range of the function is:

y > 0

In practical terms, this means that Sharlene's truck will always have some positive value, even if its market value has decreased due to depreciation. In other words, a truck is never worth zero or less than zero (unless it has additional debts associated with it), and Sharlene's truck will always have some resale or scrap value even if it has depreciated significantly.

Quadrilateral ABCD is not a rectangle because consecutive sides have slopes of 3/4 and -3/2 so they are not perpendicular

1) Considering that to be a rectangle that quadrilateral needs to have perpendicular line segments and two pairs of congruent segments.

2) Let's find the slope of the line segments AB and BC, bearing in mind the coordinates of A(-2,-1) B(2,2) and C(4,-1)

Note, that in order to state that there are perpendicular lines, the slope of AB and BC should be the opposite and reciprocal so AB is 3/4 and BC should be -4/3. The same does not occur to AB and AD.

3) Hence, the answer is:

Quadrilateral ABCD is not a rectangle because consecutive sides have slopes of 3/4 and -3/2 so they are not perpendicular

Step-by-step explanation:

The expected value of the sum of n dice is E[X] = 3.5n.

Indicator random variables are a probability theory tool. They are used to help evaluate probabilities for a given random variable.
Let X be the total number that results from n throws of a fair six-sided die.

By linearity of expectation,E[X] = E[X1 + X2 + ... + Xn] = E[X1] + E[X2] + ... + E[Xn]

Where Xj is the number obtained on the jth die roll.

Each Xi is a discrete random variable with a uniform distribution on the set {1, 2, 3, 4, 5, 6}.

To evaluate E[Xi], we define an indicator random variable Yi as follows: Yi = 1 if Xi = i and Yi = 0 otherwise.

Then, Xi = 1Y1 + 2Y2 + 3Y3 + 4Y4 + 5Y5 + 6Y6.

Thus,E[Xi] = E[1Y1 + 2Y2 + 3Y3 + 4Y4 + 5Y5 + 6Y6] = E[1Y1] + E[2Y2] + ... + E[6Y6] = 1P(Xi = 1) + 2P(Xi = 2) + ... + 6P(Xi = 6) = (1 + 2 + ... + 6) / 6 = 3.5.

Therefore, E[X] = E[X1] + E[X2] + ... + E[Xn] = 3.5n.

Thus, we have computed the expected value of the sum of n dice using indicator random variables. The expected value of the sum of n dice is E[X] = 3.5n.
