The measure of angle ∠ACB is 45 degrees

From the question, we have the following parameters that can be used in our computation:

A (-3, 2), B (0, 0), C (2, 3)

The graph is attached

The lines AB and BC are perpendicular lines

This means that

∠B = 90 degrees

Calculate the length AB and BC using

distance = √[(x2 - x1)² + (y2 - y1)²]

So, we have

AB = √[(-3 - 0)² + (2 - 0)²] = √13

BC = √[(0 - 2)² + (0 - 3)²] = √13

The angle C is then calculated as

tan(C) = AB/BC

tan(C) = √13/√13

tan(C) = 1

Take the arctan of both sides

C = 45

Hence, the measure of ∠ACB is 45 degrees

In the trigonometry relation the value of θ is 45 degrees and the coterminal angle between 0° < θ < 360° is 315 degrees

Coterminal angles are angles that have the same terminal side in a given circle. They are angles that differ by a multiple of 360 degrees.

In other words, if two angles are coterminal, they have the same trigonometric functions, despite having different degrees.

If sec θ = √2

θ = arc sec (√2)

θ = arc cos (1/√2))

θ = 45 degrees

coterminal of angle 45 degrees between 0° < θ < 360°

The complete factorization of the polynomial function f(x) = x³ - 4x² - 3x + 18 is (x + 2)(x - 22).

What is a polynomial ?

A polynomial is a mathematical expression involving a sum of powers in one or more variables (indeterminates) multiplied by coefficients.

where n is a non-negative integer (the degree of the polynomial), x is the variable, and (the coefficients of the polynomial). The highest power of x in the expression is n, and this term is called the leading term. The coefficient of the leading term, a_n, is called the leading coefficient.

To find the other linear factors of the polynomial function f(x) = x³ - 4x² - 3x + 18, we can use long division by dividing the polynomial function by (x + 2).

Here's how the long division would look like:

x³ - 4x² - 3x + 18

       ÷ x + 2

__________________________

x² - 6x - 20

             ÷ x + 2

__________________________

x - 22

       ÷ x + 2

__________________________

-20

here -20 is the remainder.

The complete factorization of the polynomial function f(x) = x³ - 4x² - 3x + 18 is (x + 2)(x - 22).

So, the other linear factors are x - 22.

What is exponential function?

An exponential function is a mathematical function in which the value of the output is proportional to the value of a fixed number (known as the base) raised to the power of the input value. The general form of an exponential function is:

                                      y = abˣ

where a and b are constants, x is the input value, and y is the output value. The constant a controls the vertical scaling of the function, while the constant b controls the rate of growth or decay. If b is greater than 1, the function grows rapidly as x increases. If 0 < b < 1, the function decays as x increases. If b is equal to 1, the function is a linear function.

Exponential functions are widely used in many fields, including finance, biology, physics, and engineering, to model growth and decay processes.

Answer: Since the perimeter of all the rectangles is equal (24 cm), the sum of the length and width of each rectangle must be equal for each rectangle. This is because the perimeter of a rectangle is equal to the sum of its lengths plus the sum of its widths, multiplied by 2.

For example, if the length of one rectangle is "l" cm and its width is "w" cm, then its perimeter would be 2l + 2w = 24 cm.

So, in general, we can write the equation: l + w = P/2, where P is the perimeter of the rectangle (in this case, P = 24 cm).

Therefore, the sum of the length and width of each rectangle is equal and constant, regardless of the individual values of the length and width. This means that as the length of a rectangle increases, its width must decrease by an equal amount to keep the sum constant. And vice versa.

In conclusion, the sum of the length and width of each rectangle is equal, and it is equal to half of the perimeter of the rectangle.

Traditionally, functions are classified as either linear or exponential, as follows:

As there is not a constant neither a multiplicative rate of change for the table, the function is neither linear nor exponential.

Considering that from x = 1 to x = 4 the rate of change is of 4/3, while from x = 16 to x = 25 the rate of change is of 4/9, that is, the increase rate decreases as x increases, the function is classified as a quadratic function.

Answer: D Im doing the quiz

Answer:D:the range is 5, and the IQR is 10.

Step-by-step explanation:

To prove that point d is equidistant from the jungle gym and monkey bars, we need to show that the distances from d to both points are equal.

Let's call the distance from d to the jungle gym "x" and the distance from d to the monkey bars "y". We need to show that x = y.

Since angle acd is a right angle, we can use the Pythagorean theorem to relate the distances:

ad^2 + cd^2 = ac^2

We know that ad = bd (since the jungle gym and monkey bars are the same distance from d), so we can write:

bd^2 + cd^2 = ac^2

We also know that c lies on ab, so we can write:

ac = ab - bc

Substituting this into our equation, we get:

bd^2 + cd^2 = ab^2 - 2abbc + bc^2

Since d is on cd, we can write cd = y, and since c is on ab, we can write ab = x + y. Substituting these into our equation, we get:

bd^2 + y^2 = (x + y)^2 - 2xy + x^2

Simplifying, we get:

bd^2 - x^2 = 2xy - y^2

Now, if we can show that bd = x, then we will have proven that y = x and therefore that point d is equidistant from the jungle gym and monkey bars.

To do this, we can use the fact that triangle adb is isosceles (since ad = bd). This means that angle adb is equal to angle bad. We also know that angle acd is a right angle. Therefore, angle adb + angle acd = 90 degrees.

Since angle adb = angle bad, we can write:

2 angle adb + angle acd = 180 degrees

Substituting in the values of our angles, we get:

2 angle adb + 90 degrees = 180 degrees

Solving for angle adb, we get:

angle adb = 45 degrees

Now, we can use the fact that triangle adb is isosceles to write:

angle bad = (180 - 45)/2 = 67.5 degrees

Finally, we can use the law of sines to relate bd and x:

bd/sin(67.5) = x/sin(45)

Simplifying, we get:

bd = x

Therefore, we have shown that point d is equidistant from the jungle gym and monkey bars.

One inequality that is equivalent to 3x<1 and 6x<2 is 3x<1/2.

To see why this is true, we can divide both sides of the second inequality by 2, which gives 3x<1/3. However, we want an inequality that is equivalent to both 3x<1 and 6x<2, so we need to find a common solution.

Notice that if 3x<1, then x<1/3. And if 6x<2, then x<1/3 as well (since 1/3 is less than 2/6). Therefore, the intersection of the solutions for these two inequalities is x<1/3.

But we want an inequality in the form of 3x<a, where a is some constant. To find this value, we need to solve for x in the intersection of the two solutions:

x<1/3

Multiplying both sides by 3 gives:

If X and Y are independent and identically distributed uniform random variables on (0, 1), then the joint density of

(a) U = X + Y, V = X/Y is u/v² for v > 1 and 0 ≤ u ≤ 1.

(b) U = X, V = X/Y is 1/v for v > 1 and 0 ≤ u ≤ 1.

(c) U = X + Y, V = X/(X+Y) is v/(1+v)² for v > 0 and v/(1+v) ≤ u ≤ 1.

In probability theory, joint density is a mathematical function that describes the probability distribution of two or more random variables. It represents the probability of occurrence of different values of those variables in a particular region of space. In this problem, we have to calculate the joint density of U and V, where U and V are functions of X and Y.

(a) For U = X + Y and V = X/Y, we can find the joint density as follows:

First, we need to find the distribution of U and V separately. Since X and Y are independent and identically distributed uniform random variables on (0, 1), their individual probability density functions are f(x) = 1 for 0 ≤ x ≤ 1.

To find the density of U, we can use the convolution formula, which states that the density of the sum of two independent random variables is the convolution of their individual densities. Thus,

fU(u) = ∫ fX(u - y)fY(y) dy

= ∫ 1 dy

= u for 0 ≤ u ≤ 1.

Next, to find the density of V, we need to transform X and Y using the change of variables formula. Let Z = X/Y, then

fV(v) = fZ(z)|dz/dv|

= fX(vz)/(z²) |z|

= 1/(v²) for v > 1.

Therefore, the joint density of U and V is given by the product of their individual densities:

fUV(u,v) = fU(u) fV(v)

= u/v² for v > 1 and 0 ≤ u ≤ 1.

(b) For U = X and V = X/Y, we can similarly find the joint density as:

fUV(u,v) = fX(u) fV(v)

= 1/v for v > 1 and 0 ≤ u ≤ 1.

(c) For U = X + Y and V = X/(X+Y), we can use the same method as in (a) to find the individual densities of U and V:

fU(u) = u for 0 ≤ u ≤ 1,

fV(v) = v/(1+v)² for v > 0.

Then, the joint density of U and V is given by:

fUV(u,v) = fU(u) fV(v) |du/dx|

= v/(1+v)² for v > 0 and v/(1+v) ≤ u ≤ 1.
