The area of the square is the side × side

We have the area

[tex]A = x^2-12x+36\\A = (x-6)^2\\A = (x-6)(x-6)[/tex]

The length of one side of the square represents [tex]x -6[/tex]

To find the height the ladder reaches on the wall, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the ladder in this case) is equal to the sum of the squares of the lengths of the other two sides.

Let's call the height the ladder reaches on the wall "h." Then we have a right triangle with sides h, 7 (the distance from the wall), and 12 (the length of the ladder).

Using the Pythagorean theorem, we have:

h^2 + 7^2 = 12^2

Solving for h:

h = sqrt(12^2 - 7^2) = sqrt(144 - 49) = sqrt(95) = 9.746781

Rounding to two decimal places, the ladder's height on the wall is 9.75 feet.

The Pythagorean theorem is a mathematical principle named after the ancient Greek mathematician Pythagoras. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The theorem can be written as an equation:

a^2 + b^2 = c^2,

Where c is the hypotenuse length, and a and b are the lengths of the other two sides.

The Pythagorean theorem has numerous applications in mathematics, physics, engineering, and other fields and is considered one of the most important theorems in mathematics.

The average velocity of a hiker that climb 0.9 km in 45 minutes is 1,2 km/hour.

Velocity is a derived quantity derived from the principal quantities of length and time, where the formula for speed is distance divided by time. Velocity is a vector quantity that indicates how fast an object is moving. Average velocity is the ratio between the displacement that occurs in an object with the time it takes to make the move.

Given,

Distance traveled = [tex]\frac{9}{10}[/tex] of 1 kilometer = 0.9 km

Time = [tex]\frac{3}{4}[/tex] of 1 hour = 0.75 hours

Velocity = [tex]\frac{distance}{time}[/tex]

Velocity =  [tex]\frac{0,9 km}{0,75 hours}[/tex]

Velocity = 1,2 kph

So that the velocity taken by the hiker is 1,2 kph.

How quickly a disease spreads through a population is shown by its incidence rate. So this measurement represent incidence type of rate. So the option A is correct.

How quickly a disease spreads through a population is shown by its incidence rate. It has a few benefits over an occurrence ratio because it is based on person-time. Person-time may account for people entering and exiting the research because it is calculated for each participant.

Incidence is the percentage or rate of people who develop a condition within a specific time period, as opposed to prevalence, which refers to the proportion of people who have a condition at or during a specific time period.

The total number of event occurrences within a given time period are represented by the COUNT metric submission type.

The mortality rate, often known as the death rate, is a measurement of the number of fatalities (generally speaking, or those caused by a particular cause) in a given population, scaled to that population's size, per unit of time.

When the curve with equation y = f(x) is reflected and squared, the transformed function of f(x) is -1/2f(y).

Transformations are a catch all term for four different kinds of changing the location and/or shape of a circle, line, or geometric figure. The words used are the Pre-Image, which describes the shape of the object at first, and the Image, it describes the final shape and location of the object following alteration.

Given,  Ryan is making a fruit drink. The directions say to mix 3 cups of water with 1 1/2 scoops of powdered fruit mix.

We have to find how many cups of water should he use with 6 scoops of fruit mix

Let "n" be the number of cups required for 6 scoops of fruit mix

3 cups of water ⇒ 1.5 scoops of fruit mix.

Then, n cups of water ⇒ 6 scoops of fruit mi

So, by cross multiplication,

6 * 3 = n *1.5

n = 12

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Mathematically, it can be expressed as c² = a² + b² where c is the length of the hypotenuse and a and b are the lengths of the other two sides. The theorem can be proven using Euclidean geometry.

In a right angle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In short it is written as: a² + b² = c²

For example, if the sides are 6cm and 8cm, the hypothenuse will be:

c² = 6² + 8²

c² = 100

The probability of grabbing 2 consecutive orange pieces is approximately 0.101.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The probability of grabbing 2 consecutive orange pieces without replacement is calculated as:

[tex]\frac{30}{100}[/tex] × [tex]\frac{29}{99}[/tex] = 0.090/0.9 = 0.101010101...

The combined perimeter and area of all three rectangular corrals can be represented algebraically as follows:

Total perimeter = 3 * (12x - 4) = 36x - 12

Total area = 3 * (5x^2 - 2x) = 15x^2 - 6x

Let x be the width of each rectangular corral.

L = 5x - 2

          P = 2(L + x)

             = 2(5x - 2 + x)

             = 2(6x - 2)

             = 12x - 4

         A = L * x

             = (5x - 2) * x

w = 4 + (3 x 5) since p = 5

w = 4 + (15)

w = 19

Answer:

w = 19

If the equation is w = 4 + 3p, we can substitute the 'p' for five.

To solve for w, we need to first solve 3 times 5.

Therefore if p = 5, w = 19.

The probability of choosing $11 dollar bags from a total of 6 bags is 1/6.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

In probability, a real-valued function, defined over the sample space of a random experiment, is called a random variable. That is, the values of the random variable correspond to the outcomes of the random experiment. Random variables could be either discrete or continuous.

The probability of winning $11 = Probability of choosing $10 bag * Probability of choosing $1 bag

The probability of choosing a $1 bag first = 5/6

Probability of choosing $10 bag second  = 1/5

Therefore the probability of choosing $11 dollar bags = 1/5 * 5/6 = 1/6

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols.

The two-given system of equations are:

−3x + 3y ≤ −9

Isolating the value of y in equation 2 we have:

−3x + 3y ≤ −9

3y ≤ 3x - 9

y ≤ x - 3

The first equation can also be written as:

The kinetic energy of the object is 4 * π^2 * m * r^2 * n^2, which is option D.

The kinetic energy of an object with mass m and velocity v can be calculated as 1/2 * m * v^2.

In this case, the velocity of the object can be calculated as the circumference of the circle (2 * π * r) multiplied by the number of revolutions per second (n), so v = 2 * π * r * n.

Substituting this expression for v into the equation for kinetic energy, we get:

1/2 * m * (2 * π * r * n)^2 = 1/2 * m * (4 * π^2 * r^2 * n^2) = 4 * π^2 * m * r^2 * n^2.

Step-by-step explanation:

The expression x = ce−2t is a solution of the initial condition is x(0) = 100 and x (0) = −2x.

In mathematics and particularly in dynamic systems, an initial condition, in some contexts called a seed value, is a value of an evolving variable at some point in time designated as the initial time (typically denoted t = 0).

Differentiating the function x = ce−2t

x = ce−2t with respect to t ,

We have:

x ′ = d/dt (Ce−2t)

x ′ = C(−2e−2t)

x ′ = −2(Ce−2t)

x ′= −2x. x ′

x ′ = d / d t ( C e − 2 t )

x ′= C ( − 2 e − 2 t )

x ′= − 2 ( C e − 2 t )

x ′= − 2 x .

Therefore,
