Find the exact length of line segment PQ

The  speed describes as :  A scalar quantity with magnitude only.

What is speed?

Speed is distance travelled by the object per unit time. Due to having no direction and only having magnitude, speed is a scalar quantity With SI unit meter/second.

Some more information about speed:

When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed.

When an object travels a different distance at regular intervals, it is said to have variable speed.

Average speed is the constant speed determined by the ratio of the total distance travelled by an object to the total amount of time it took to travel that distance.

The quotient of the rational expression given is [tex]\frac{2x - 1}{3x}[/tex] , and option A is the correct answer.

The ratio of two polynomials is displayed in rational expressions. It indicates that the denominator and numerator are polynomials. It is an algebraic expression that has a ratio and an unknown variable, just like a fraction. Although we can simplify this kind of equation with the aid of a calculator.

Polynomial expressions must be set equal to zero in order to find the root or zero. However, once the expression has been condensed to its simplest form, we must only set the numerator equal to zero in order to obtain the zeros of rational functions or expressions.

The given rational expression is:

Trigonometry is one of the most important branches in mathematics. The word trigonometry is formed by clubbing words 'Trigonon' and 'Metron' which means triangle and measure respectively. It is the study of the relation between the sides and angles of a right-angled triangle. It thus helps in finding the measure of unknown dimensions of a right-angled triangle using formulas and identities based on this relationship. Trigonometry basics deal with the measurement of angles and problems related to angles. There are three basic functions in trigonometry: sine, cosine, and tangent. These three basic ratios or functions can be used to derive other important trigonometric functions: cotangent, secant, and cosecant. All the important concepts covered under trigonometry are based on these functions. Hence, further, we need to learn these functions and their respective formulas at first to understand trigonometry.

Given the terminal point we know the following:

Adjacent = -48

Opposite = -55

Hypotenuse can use the Pythagorean Theorem to find:

c²=(-48)²+(-55)² = 5329

Take the square root of both sides

c=√5329 = 73

So, sin θ = -55/73

cos θ = -48/73

tan θ = 55/48

csc θ = 73/-55

sec θ = 73/-48

cot θ =48/55

Thus, the required values are sin θ = -55/73, cos θ = -48/73, tan θ = 55/48, csc θ = 73/-55, sec θ = 73/-48, cot θ =48/55

The correct answer is C. 0.25 foot.

To find the depth of the mulch, we need to determine the volume of the circular mulch bed and divide it by the area. The volume of a cylinder can be calculated as:

V = πr^2h

where r is the radius and h is the height (or depth) of the cylinder.

For the circular mulch bed, the radius is 1.6 feet and we want to find the height (or depth), so we can set the volume equal to the volume of the mulch:

V = π * 1.6^2 * h

V = 2 cubic feet

Solving for h:

h = V / (π * r^2)

h = 2 / (π * 1.6^2)

Using the value of π = 3.14, we get:

h = 2 / (3.14 * 1.6^2)

h = 0.24 inches

Therefore, the depth of the mulch is approximately 0.24 inches to the nearest hundredth of an inch, which is the appropriate number of significant digits.

To convert inches to feet, divide the number of inches by 12:

0.24 inches / 12 inches/foot = 0.02 feet

Rounding to the nearest hundredth of a foot, we get 0.25 feet as the answer.

To find the order and degree of a given differential equation, simply count the highest derivative and the highest power of the unknown function that appear in the equation.

What is a differential equation?

A differential equation is an equation that relates an unknown function and its derivatives to some given functions or constants.

The order of a differential equation is defined as the order of the highest derivative appearing in the equation. For example, if a differential equation contains only the first derivative of the unknown function, it is said to be a first-order differential equation. If it contains the second derivative, it is a second-order differential equation, and so on.

The degree of a differential equation is defined as the highest power of the unknown function in the equation. For example, if a differential equation is of the form y' + 2y = 0, the degree of the differential equation is 1 (the highest power of y is 1). If it is of the form y'' + 4y = 0, the degree of the differential equation is 2 (the highest power of y is y^2).

Coefficient estimates from WLS (weighted least squares) are interpreted in a similar manner to those from an un-weighted, original model. The main difference is the weights used to scale the observations.

Therefore, correct answer will be:-  Coefficient estimates from the un-weighted, original model should be used for prediction

This can cause estimates to differ depending on the weight chosen. When interpreting the coefficient estimates, it is important to consider the weights used when calculating the model. This is because they can affect the magnitude of the coefficient estimates.

Additionally, the weights should be taken into account when calculating the marginal effects of the coefficients. This can be done by scaling up the coefficients by the weight used. Ultimately, the interpretation of coefficient estimates from WLS should be done in the same manner as those from an un-weighted model, but the weights should be taken into account when considering their magnitude and when calculating marginal effects.

The height of the rectangle is equal to -2x² - 3x + 35.

The height of a rectangle can be found by subtracting the value of one of its side lengths from the value of the other side length.

We know that the height is equal to the difference between two side lengths, which are represented by the expressions y1 = -2x²+20 and y2 = 3x-15.

To find the height, we subtract y2 from y1:

y1 - y2 = (-2x²+20) - (3x-15) = -2x² - 3x + 35

So, the height of the rectangle is equal to -2x² - 3x + 35.

The number of people on the escalator during rush hour will depend on how long rush hour lasts, so it is not possible to provide a single answer without knowing the length of rush hour.

At rush hour, two people per second step onto the escalator, so in one second, 2 people get on the escalator.

The escalator takes 20 seconds to bring a person from the bottom to the top, so for every 20 seconds, 2 people get on the escalator and 2 people get off the escalator.

To find the number of people on the escalator during rush hour, we need to determine the number of people on the escalator after a certain amount of time, say t.

The number of people on the escalator at time t can be calculated as follows:

people on the escalator at time t = 2 * t - 2 * floor(t / 20)

where floor(t / 20) represents the number of complete cycles (20 seconds each) that have occurred.

For example, if t = 40 seconds, then floor(t / 20) = 2, so the number of people on the escalator would be:

people on the escalator at time 40 = 2 * 40 - 2 * 2 = 76
