What is the equation of the line that passes through the point (7, 2) and has a slope of 1?

Answer:

80%

Step-by-step explanation:

original: 1

Increase 25%: 1.25  if this number becomes 1

1 : 1.25 = x : 1

x = 1 / 1.25 = 0.8   (80%)

check: 0.8 x 1.25 = 1

Answer:

y= -2/5x - 6

Step-by-step explanation:

Use Rise/Run with any of the given points! You go up two, left 5. That proves the slope is -2/5. The line hits the Y axis at -6, so the y-intercept is -6!

(a) Strings in L: "abb", "aabbb". (b) Strings not in L: "aabb", "bb".

(c) State diagram for a deterministic Turing Machine with 10 states is given below.

(a) Two strings that are in L are:

1. `abb` (Here, i = 0, and w is an empty string).

2. `aabbb` (Here, i = 2, and w = "aa").

(b) Two strings over the same alphabet that are not in L are:

1. `aabb` (Here, the length of w is 2, but there are more than two 'a's before the 'bb').

2. `bb` (Here, the length of w is 0, but there are 'b's before the 'bb', violating the condition).

(c) Here is the state diagram for a deterministic Turing Machine with 10 states that decides L:

```START --> A --> B --> C --> D --> E --> F --> G --> H --> ACCEPT

  a      b      b      a      a      b      b      a      b

The polar radius of gyration represents the distance from the point A to an axis that would result in the same moment of inertia as the actual area.

The polar radius of gyration, \( k_{A} \), for the area of the angle section about point A can be calculated using the formula:

\( k_{A} = \sqrt{\frac{{I_{A}}}{{A}}} \),

where \( I_{A} \) is the moment of inertia about point A and \( A \) is the area of the angle section. Since the width of the legs is small compared to their lengths, we can approximate the moment of inertia using the parallel axis theorem, which states that \( I_{A} = I_{G} + Ad^{2} \), where \( I_{G} \) is the moment of inertia about the centroid of the angle section, \( A \) is the area, and \( d \) is the distance between the centroid and point A. For an angle section, the moment of inertia about its centroid can be calculated as:

\( I_{G} = \frac{{l_{1}^{3}h_{1} + l_{2}^{3}h_{2}}}{{12}} \),

where \( l_{1} \) and \( l_{2} \) are the lengths of the legs, and \( h_{1} \) and \( h_{2} \) are the heights of the legs.

Using the given formula and values, we can calculate \( k_{A} \).

The polar radius of gyration of the area of the angle section about point A is \( k_{A} = \frac{{l_{1}^{3}h_{1} + l_{2}^{3}h_{2}}}{{l_{1}h_{1} + l_{2}h_{2}}} \) inches.

(a) Both particles have the same value of k_B T.

(b) The smaller particle has a greater value of γ.

(c) The smaller particle has a greater value of D.

a) To show γD = k_B T, we start with the given relations:

⟨v0,x^2⟩ = (Δt/L)^2

γ = Δt/(2m)

D = (2Δt)/(L^2)

Substituting the expression for γ into the equation for D:

D = (2Δt)/(L^2) = (2Δt)/(L^2) * Δt/(2m) = (Δt^2)/(mL^2) = γ^2/m

Now, multiplying γ and D:

γD = γ * D = γ^2/m = (Δt/(2m))^2/m = Δt^2/(4m^2) = (1/4m) * (Δt^2/m) = (1/4m) * γ = (1/4m) * (Δt/(2m)) = (k_B T)/(4m)

Since k_B T is the average kinetic energy per degree of freedom and (1/4m) is the average kinetic energy per particle, we can equate γD and k_B T:

γD = k_B T

b) The dependence of γD on m is 1/m. As we can see from the equation γD = (k_B T)/(4m), as the mass (m) increases, the value of γD decreases.

c) When comparing two spherical particles in the same solution:

Greater value of k_B T: Both particles will have the same value of k_B T since it depends on temperature (T) and is independent of the size or mass of the particles.

Greater value of γ: The smaller particle will have a greater value of γ. As γ = Δt/(2m), since the mass of the smaller particle is smaller, the value of γ will be greater.

Greater value of D: The smaller particle will have a greater value of D. As D = (2Δt)/(L^2), since the time between collisions (Δt) will be smaller for the smaller particle due to its faster movement, the value of D will be greater.

Step-by-step explanation:

Part a:

The value of the gradient G for the royalty stream is $5,143.

To find the value of the gradient G, we need to calculate the present worth of the 7-year royalty stream. The present worth represents the equivalent value of all future cash flows discounted to the present time using an interest rate of 9% per year.

Let's denote the value of the gradient G as G. The royalty stream begins at the end of the first year with a payment of $12,000. From year 2 to year 7, the royalty stream changes by G each year. Therefore, the cash flows for each year are as follows:

Year 1: $12,000

Year 2: $12,000 + G

Year 3: $12,000 + 2G

Year 4: $12,000 + 3G

Year 5: $12,000 + 4G

Year 6: $12,000 + 5G

Year 7: $12,000 + 6G

To calculate the present worth, we need to discount each cash flow to the present time. Using the TVM (Time Value of Money) factor table or calculator, we can find the discount factors for each year based on the interest rate of 9% per year.

Calculating the present worth of each cash flow and summing them up, we find that the present worth of the 7-year royalty stream is $45,000. Therefore, we can set up the following equation:

$45,000 = $12,000/(1+0.09)^1 + ($12,000+G)/(1+0.09)^2 + ($12,000+2G)/(1+0.09)^3 + ($12,000+3G)/(1+0.09)^4 + ($12,000+4G)/(1+0.09)^5 + ($12,000+5G)/(1+0.09)^6 + ($12,000+6G)/(1+0.09)^7

Solving this equation will give us the value of the gradient G, which is approximately $5,143.

Part b:

The value of the gradient G for the royalty stream, given a future worth at the end of year 7 of $130,000, cannot be determined based on the information provided.

3x + 7y = 27      --------------(I)

-3x + y = 21        -----------(II)

Add equation (I) & (II) and so x will be eliminated and we can find the value of y.

(I)      3x + 7y = 27    

(II)     -3x + y = 21        {add}

the maximum height of a quadratic equation can be find Use the formula: x = -b / (2a) then Substitute the value of x back into the quadratic equation to find the corresponding maximum height.

To find the maximum height of a quadratic equation, you need to determine the vertex of the parabolic curve. The vertex represents the highest or lowest point of the quadratic function, depending on whether it opens upward or downward.

A quadratic equation is generally written in the form of y = ax² + bx + c, where "a," "b," and "c" are coefficients.

The x-coordinate of the vertex can be found using the formula: x = -b / (2a). This formula gives you the line of symmetry of the parabola.

Once you have the x-coordinate of the vertex, substitute it back into the original equation to find the corresponding y-coordinate.

The resulting y-coordinate represents the maximum height (if the parabola opens downward) or the minimum height (if the parabola opens upward) of the quadratic equation.

Here's an example:

Consider the quadratic equation y = 2x² - 4x + 3.

1. Identify the coefficients:

a = 2

b = -4

c = 3

2. Find the x-coordinate of the vertex:

x = -(-4) / (2 * 2) = 4 / 4 = 1

3. Substitute x = 1 back into the equation to find the y-coordinate:

y = 2(1)² - 4(1) + 3 = 2 - 4 + 3 = 1

Therefore, the maximum height of the quadratic equation y = 2x² - 4x + 3 is 1.

The maximum height of a quadratic equation can be found by determining the vertex of the parabolic shape represented by the equation. The x-coordinate of the vertex can be found using the formula x = -b / (2a), and the corresponding y-coordinate represents the maximum height.

To find the maximum height of a quadratic equation, we need to determine the vertex of the parabolic shape represented by the equation. The vertex is the point where the parabola reaches its highest or lowest point.

The general form of a quadratic equation is ax^2 + bx + c, where a, b, and c are constants. To find the x-coordinate of the vertex, we can use the formula x = -b / (2a).

Once we have the x-coordinate, we can substitute it back into the equation to find the corresponding y-coordinate, which represents the maximum or minimum height of the quadratic equation.

Let's take an example to illustrate this process:

Suppose we have the quadratic equation y = 2x^2 + 3x + 1. To find the maximum height, we first need to find the x-coordinate of the vertex.

Using the formula x = -b / (2a), we can substitute the values from our equation: x = -(3) / (2 * 2) = -3/4.

Now, we substitute this x-coordinate back into the equation to find the y-coordinate: y = 2(-3/4)^2 + 3(-3/4) + 1 = 2(9/16) - 9/4 + 1 = 9/8 - 9/4 + 1 = 9/8 - 18/8 + 8/8 = -1/8.

The lower limit for the standard deviation is always 0, while the upper limit depends on the data and its distribution.

The standard deviation is a measure of the spread or dispersion of a set of data. It is defined as the square root of the variance, which is the average of the squared differences between each data point and the mean of the data. Since the variance involves squaring the differences, it is always positive or zero. Therefore, the standard deviation cannot be negative and has a lower limit of 0.

The upper limit of the standard deviation depends on the data and its distribution. In general, the standard deviation cannot be greater than the range of the data, which is the difference between the maximum and minimum values. For example, if the range of the data is 10 and the standard deviation is 15, then there must be an error or some issue with the data.

However, in some cases, the standard deviation can be much larger than the range of the data. This can happen if the data is highly skewed or has outliers. Skewed data is when the distribution of the data is not symmetrical, and most of the data falls on one side of the mean. In this case, the standard deviation may be much larger than the range of the data, as it takes into account the extreme values.

Outliers are data points that are much larger or smaller than the rest of the data. They can have a significant effect on the standard deviation, as they increase the variability of the data. In some cases, outliers may be errors or anomalies that should be removed from the data set before calculating the standard deviation.

In summary, the lower limit of the standard deviation is always 0, while the upper limit depends on the data and its distribution. In general, the standard deviation cannot be greater than the range of the data, but it can be much larger if the data is highly skewed or has outliers. It is important to consider the context of the data and any potential issues before interpreting the standard deviation.

To find the angle of the rise of a bridge, given that it rises 500 feet per one-half mile, we can use the trigonometric function tangent (tan).

The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right triangle.

In this case, we can consider the height of the bridge (500 feet) as the side opposite the angle and the horizontal distance (one-half mile or 2640 feet) as the side adjacent to the angle.

Using the formula:

tan(θ) = opposite/adjacent

tan(θ) = 500/2640

To find the angle (θ), we can take the inverse tangent (arctan) of both sides:

θ = arctan(500/2640)

Using a calculator, we find that:

θ ≈ 11.22 degrees

Therefore, the angle of the rise of the bridge would be approximately 11.22 degrees.

We can use the Pythagorean theorem to solve this problem. Let's call the length of the ladder "L". The ladder, the wall of the house, and the ground form a right triangle. The distance between the ladder and the house is the base of the triangle, which is 15 feet. The height of the triangle is the distance from the ground to the spotlight, which is 20 feet. The length of the ladder is the hypotenuse of the triangle.

Using the Pythagorean theorem, we have:

L^2 = 15^2 + 20^2

L^2 = 225 + 400

L^2 = 625

L = sqrt(625)

L = 25

Therefore, a ladder of at least 25 feet is needed for the electrician to reach the place where the light is mounted.
