The Pythagoras is the sum of the square of two sides is equal to the square of the longest side. The height of the house is 12 feet, then the correct option is B.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

Miguel places his 13-foot ladder 5 feet from the edge of his house.

Then the height of the house is given by the Pythagoras theorem.

P² = H² - B²

P² = 13² - 5²

P² = 169 - 25

P² = 144

P = 12

Then the height of the house is 12 feet.

For the sinusoidal function that gives the temperature hours after midnight, the amplitude will be (f - f)/2 = |f - f|/2 = f/2

Let's start by finding the amplitude of the sinusoidal function. The amplitude is half the difference between the high and low temperatures:

amplitude = (f - f)/2 = |f - f|/2 = f/2

Next, we need to find the period of the sinusoidal function, which is the length of one cycle of the function. The period is 24 hours, since the temperature repeats itself every 24 hours.

Finally, we need to find the phase shift of the sinusoidal function, which is how many hours after midnight the function starts. Since the temperature is f at midnight, the phase shift is zero.

Putting all of this together, we can write the formula for the sinusoidal function as:

f(t) = (f/2)sin(2π/24(t-0)) + f

where t is the number of hours after midnight and f(t) is the temperature at that time.

Let's create a sinusoidal function that models the outdoor temperature over a 24-hour period.

Step-by-step explanation:

Giben the triangles:

ABC and PQR

Thiangle PQR is a reduction of triangle ABC, this means that the sides of triangle ABC were divided by a reduction factor to determine the side lengths of triangle PQR.

Using the lengths of sides AB and its correspoding side PQ you can calculate the used reduction factor k following the formula:

Using this relationship you can determine the value of the reduction factor

The reduction factor is k=4

Now that we have determined the factor, we can calculate the length of PR as:

The length of PR=6, so the correct option is C.

To find the solution for the given system of differential equations, we can use the initial conditions at t = 0 to determine the values of y1(0) and y2(0), which are both given as 1.

Using these initial conditions, we can solve the system of equations:

y1' = -13y1 + 56y2,

y2' = -4y1 + 17y2.

To solve this system, we can express it in matrix form:

Y' = AY,

where Y = [y1, y2] and A is the coefficient matrix:

A = [-13 56]

[-4 17].

The solution to this system can be found by diagonalizing the coefficient matrix A. Let's calculate the eigenvalues and eigenvectors:

The eigenvalues λ can be found by solving the characteristic equation det(A - λI) = 0, where I am the identity matrix:

det(A - λI) = (-13 - λ)(17 - λ) + 4*56 = λ^2 - 4λ + 8 = (λ - 2)^2 + 4.

Solving the characteristic equation, we get λ = 2 ± 2i.

For each eigenvalue, we can find the corresponding eigenvector by solving the system (A - λI)V = 0:

For λ = 2 + 2i, we have the eigenvector V1 = [4 - 2i, 1].

For λ = 2 - 2i, we have the eigenvector V2 = [4 + 2i, 1].

Now, we can write the general solution as:

Y(t) = c1V1e^(λ1t) + c2V2e^(λ2t),

where c1 and c2 are constants determined by the initial conditions.

Plugging in the initial conditions at t = 0:

Y(0) = c1V1 + c2V2 = [1, 1],

we can solve for c1 and c2: c1V1 + c2V2 = [1, 1].

Solving this system of equations, we can find the values of c1 and c2.

Finally, substituting the values of c1, c2, V1, V2, λ1, and λ2 into the general solution, we obtain the specific solution for the given initial conditions at t = 0: Y(t) = [y1(t), y2(t)].

Answer:

No.

Step-by-step explanation:

The ratio of the lengths of the vertical sides from A to B is 2/4 which equals 1/2.

The ratio of the lengths of the horizontal sides of A to B is 4/11.

Since 4/11 is not equal to 1/2, figure B is not a scale copy of figure A.

The circumference of the circle with diameter d=28 cm is 28π cm.

The formula for finding the circumference of a circle is C = πd

where C is the circumference and d is the diameter.

Therefore, using the given diameter d = 28 cm, the circumference of the circle can be calculated as follows:

C = πd = π(28 cm) = 28π cm

The circumference of the circle with diameter d = 28 cm is 28π cm.

Circumference is a significant measurement that can be obtained through diameter measurement. To determine the circle's circumference with a given diameter, the formula C = πd is used. In this formula, C stands for circumference and d stands for diameter. In order to calculate the circumference of the circle with diameter, d=28 cm, the formula can be employed.

The circumference of the circle with diameter d=28 cm is 28π cm.

In conclusion, the formula C = πd can be utilized to determine the circumference of a circle given the diameter of the circle.

Answer:

2.6 kilometers

Step-by-step explanation:

To find the circumference of a circle, we can use the formula:

Circumference = π * diameter

Given that the diameter of the volcanic crater is 840 meters, we can substitute this value into the formula:

Circumference = π * 840

Using the approximate value of π as 3.14159, we can calculate the circumference:

Circumference = 3.14159 * 840

Circumference ≈ 2643.1796 meters

To convert the circumference to kilometers, we divide the value by 1000:

Circumference in kilometers = 2643.1796 / 1000

Circumference ≈ 2.6432 kilometers

Therefore, the circumference of the rim of the volcanic crater is approximately 2.6 kilometers (rounded to 1 decimal place).

Let's denote the mass of plums produced by each plum tree in 2019 as x kg.

According to the given information, in 2020 each plum tree produced 37.7 kg of plums, which was 16% more than in 2019.

Mathematically, we can express this relationship as:

x + 0.16x = 37.7

Simplifying, we get:

1.16x = 37.7

To solve for x, we can divide both sides of the equation by 1.16:

x = 37.7 / 1.16

Using a calculator, we find:

x ≈ 32.6724

So, the mass of plums produced by each plum tree in 2019 was approximately 32.6724 kg.

Answer:

i think it might be number 1

Step-by-step explanation:

hi <3

i'm not sure of which method you will have been taught but i'll try to explain the method i was shown.

so, you need to multiply the coefficient of x^2 by the last value

3 x -12 = -36

now, you need to find two values that multiply to make -36 but add to make 5.

9 and 4 would work. it would have to be positive 9 and negative 4, as these would subtract to give the 5 that you need

now we have:

(x - 4)(x + 9)

however, we need to achieve the 3 from somewhere so it needs to be divided somewhere

9 is divisible by 3 so you can divide it there. as 4 cannot divide by 3, you would move the 3 up to be the coefficient.

thus, your final answer would be:

(3x - 4)(x + 3)

hope this helps :)

The following equation could be used to represent a function w:

= w(x)=v(x-7)+7

According to the information provided,

The point of discontinuity of rational functions is at x=7.

When a rational function has a point of discontinuity, it generally occurs when,

q(x) = r(x-a), where x = a

In this case, we must pay attention to the following relationship, which is a combination of a parent rational function and a vertical translation:, (2)

If we know that a=7 and k=7.

The equation which can represent w is as follows,

w(x) = v ( x-7 ) + 7

A rational function can be represented as a polynomial split by another polynomial. Because polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros in the denominator.

Example: x = f(x) (x - 3). The denominator, x = 3, has only one zero. Rational functions are no longer defined when the denominator is zero.
