The x tells us the movements are right or left. Right would be a positive movement and left would be a negative movement.

The y tells us the movements are up or down.  Up would be a positive movement and down would be a negative movement.

D is at the point ( -3,5)  

(x + 6, y -4)  Is telling us that from the point of D, move right 6 spaces and down 4 spaces.  You will know be at the point (3,1).

Therefore, there are 6 possible sandwiches in this scenario.

If the bakery offers chicken, tuna, and vegetable sandwiches on plain or onion bagels, there are a total of 3 sandwich fillings (chicken, tuna, vegetable) and 2 types of bagels (plain, onion). To determine the number of possible sandwiches, we multiply the number of options for each component:

Number of sandwich fillings: 3

Number of types of bagels: 2

Total number of possible sandwiches = Number of sandwich fillings * Number of types of bagels = 3 * 2 = 6

The rate at which calories are burned was gotten by finding the slope of the graph which gives; 4 calories per minute

To get the slope of a linear graph, we will take two coordinates and make use of the formula;

Slope = (y₂ - y₁)/(x₂ - x₁)

The two coordinates we will pick for this slope are;

(10, 40) and (20, 80)

Thus;

Slope = (80 - 40)/(20 - 10)

Slope = 40/10

Slope = 4

Since the y-axis represents calories burned and the x-axis represents minutes of exercise, then we can say that;

Answer:

To find the slope of the line, you can use the formula for slope: slope = (y2 - y1)/(x2 - x1). In this case, you can rewrite the equation 2-y = 8x as y = 2 - 8x. This is the standard form of a line: y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).

Since the equation of the line is already in standard form, you can find the slope by looking at the coefficient of the x term. In this case, the coefficient of the x term is -8, so the slope of the line is -8.

Alternatively, you can plug in the coordinates of two points on the line into the formula for slope to find the slope. For example, if you know that the line passes through the points (1, -14) and (2, -10), you can use these points to find the slope:

slope = (y2 - y1)/(x2 - x1) = (-10 - (-14))/(2 - 1) = (-10 + 14)/1 = 4/1 = 4

This method gives the same result as using the standard form of the equation.

Step-by-step explanation:

Trevor and Kim will be situated 21 kilometers apart from each other at 1:30 PM. They will be separated by a distance of 21 km when the clock strikes 1:30 in the afternoon.

To determine at what time Trevor and Kim will be 21 km apart, we can set up a distance-time equation based on their relative speeds and distances.

Let's assume that t represents the time elapsed in hours since noon. At time t, Trevor would have traveled a distance of 8t km, while Kim would have traveled a distance of 6t km in the opposite direction.

Since they are running in opposite directions, the total distance between them is the sum of the distances they have traveled:

Total distance = 8t + 6t

We want to find the time when this total distance equals 21 km:

8t + 6t = 21

Combining like terms, we have:

14t = 21

To solve for t, we divide both sides of the equation by 14:

t = 21 / 14

Simplifying, we find:

t = 3 / 2

So, they will be 21 km apart after 3/2 hours, which is equivalent to 1 hour and 30 minutes.

Therefore, Trevor and Kim will be 21 km apart at 1:30 PM.

The general solution for the given higher-order linear ODE is:
y(x) = y_c(x) + y_p(x) = C1 * e^(2x) + C2 * x * e^(2x) + (1/2) * x^2 * e^(2x)

To solve the given higher-order linear ODE, we need to find a particular solution for the equation:
y'' - 4y' + 4y = e^(2x)

First, we find the complementary function (solution of the homogeneous equation) by solving the characteristic equation:

r^2 - 4r + 4 = 0

(r - 2)^2 = 0

The roots are r1 = r2 = 2. Therefore, the complementary function is:
y_c(x) = C1 * e^(2x) + C2 * x * e^(2x)

Next, we find a particular solution y_p(x) by using the method of undetermined coefficients. Since the right-hand side of the equation is e^(2x), we can assume a particular solution of the form:

y_p(x) = A * x^2 * e^(2x)

Taking the first and second derivatives of y_p(x):

y_p'(x) = A * (2x * e^(2x) + 4x^2 * e^(2x))

y_p''(x) = A * (2 * e^(2x) + 8x * e^(2x) + 8x^2 * e^(2x))

Now substitute y_p, y_p', and y_p'' back into the given ODE:

A*(2 * e^(2x) + 8x * e^(2x) + 8x^2 * e^(2x)) - 4A*(2x * e^(2x) + 4x^2 * e^(2x)) + 4A*x^2 * e^(2x) = e^(2x)

Simplify and cancel out the terms:

2A * e^(2x) = e^(2x)

A = 1/2

Now we have the particular solution:
y_p(x) = (1/2) * x^2 * e^(2x)

The general solution for the given higher-order linear ODE is:
y(x) = y_c(x) + y_p(x) = C1 * e^(2x) + C2 * x * e^(2x) + (1/2) * x^2 * e^(2x)

The measure of angle ROP is 25 degrees.

In the given diagram, TP and TR are tangents to a circle centered at O, and PRT is a triangle with angle PRT equal to 65 degrees. We need to find the measure of angle ROP in degrees.

Therefore, ∠PTO and ∠RTO are both 90 degrees.

We also know that the sum of the angles in a triangle is 180 degrees. Therefore, we can use this fact and the given angle PRT to find the measure of angle POR as follows:

∠PRT + ∠PTR + ∠PTR = 180 degrees

65 + 90 + 90 = 180 degrees

245 degrees = 180 degrees + ∠POR

∠POR = 65 degrees

Finally, we can find the measure of angle ROP by subtracting ∠POR from the given angle ∠TOR:

∠ROP = ∠TOR - ∠POR

∠ROP = 90 - 65

∠ROP = 25 degrees

In terms of relative growth rate Exponential growth is characterized by a constant relative growth rate.

Exponential growth is the process of increasing quantity over time. Occurs when the instantaneous rate of change of a quantity over time is proportional to the quantity itself. The exponential growth model has the form

y (t) = C eᵏᵗ, where k is the rate constant.

Relative Growth Rate:Relative growth rate (RGR) is the rate of growth relative to size. That is, the rate of growth per unit time relative to the size at that point in time and y'(t)/y(t) is the relative growth rate of a function y at time t.

1/y dy/dt = 1/y d(C eᵏᵗ)/dt

= 1/y(kC eᵏᵗ)

= 1/y ( ky) ( since, y (t) = C eᵏᵗ)

By using normal distribution of probability, it can be calculated that

13.59 %of men are between 64 and 66.5 inches tall

What is normal distribution of probability?

Normal distribution of probability is a continuous type probability distribution whose probability density function is given by

f(x) = \(\frac{1}{\sigma \sqrt{2\pi}}e^{-\frac{z^2}{2}}\) where z = \(\frac{x - \mu}{\sigma}\)

\(\mu\) is the mean and \(\sigma\) is the standard deviation.

Here, normal distribution of probability is used

Mean = 69 inches

Standard deviation = 2.5 inches

P(64 < X < 66.5) = P(X <66.5) - P(X < 64)

For X < 64

z = \(\frac{64 - 69}{2.5}\) = -2

P(X < 64) = P(z < -2) = 0.0228

For X < 66.5

z = \(\frac{66.5 - 69}{2.5}\) = -1

P(X < 66.5) = P(z < -1) = 0.1587

P(64 < X < 66.5) = 0.1587 - 0.0228 = 0.1359
