The value of y is 24.

Non of the given option is correct.

To find the value of y in the given triangle, we can apply the Pythagorean theorem.

The Pythagorean theorem states that in a right-angled 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.

In the given triangle, we have a right angle and one leg of length 12. The other leg has a length of 12√3. Let's assume y represents the length of the hypotenuse. Applying the Pythagorean theorem, we have:

(12)^2 + (12√3)^2 = y^2

144 + 432 = y^2

576 = y^2

Taking the square root of both sides, we get:

y = √576

y = 24

To prove that the given transformation T is a linear transformation, we need to show that it satisfies the two conditions of linearity which are Additivity and homogeneity

1. Additivity: T(v1 + v2) = T(v1) + T(v2)
2. Homogeneity: T(c * v) = c * T(v)

where v1 and v2 are vectors, and c is a scalar constant.

Given T(c1 * v1 + c2 * v2), we want to show that it equals c1 * T(v1) + c2 * T(v2).

Step 1: Apply the transformation T to the sum of the vectors c1 * v1 + c2 * v2.
T(c1 * v1 + c2 * v2)

Step 2: Use the additivity property of linear transformations.
T(c1 * v1) + T(c2 * v2)

Step 3: Use the homogeneity property of linear transformations.
c1 * T(v1) + c2 * T(v2)

Since we have shown that T(c1 * v1 + c2 * v2) = c1 * T(v1) + c2 * T(v2), we can conclude that the given transformation T is indeed a linear transformation.

We need 1.75 litres of water to make 2 litres of diluted squash with a ratio of 1 part squash to 7 parts water

To make 2 litres of diluted squash with a ratio of 1 part squash to 7 parts water, we need to calculate how much water is needed.

We can do this by using the following formula:

Water = Diluted Squash - Squash First, we need to find out how much squash is in 2 litres of diluted squash.

Since the ratio is 1:7, we can divide 2 litres by the total number of parts (1 + 7 = 8) to find out how much squash is in 2 litres of diluted squash: Squash = 2 litres / 8 = 0.25 litres

Now we can use the formula to find out how much water is needed:

Water = 2 litres - 0.25 litres = 1.75 litres

Therefore, we need 1.75 litres of water to make 2 litres of diluted squash with a ratio of 1 part squash to 7 parts water.

Answer:

the greatest common factor is 18

Step-by-step explanation:

just trust it is hard to explain

Answer:

it is 18

Step-by-step explanation:

An ordinal scale provides more information than a nominal scale since values linked with an ordinal variable will be in natural order, whereas values connected with the nominal variable won't.

Ordinal variables as well as nominal variables are the two categories of variables listed here. This sort of variable cannot be submitted to the same forms of statistical tests as interval and ratio variables, hence it is crucial to be able to recognize them accurately. Both of these variables fall within the qualitative category. This contrasts with interval as well as rate variables, both of which are categorized as quantitative.

An illustration of an ordinal variable is a Likert scale with words for mood (such as joyful, neutral, or sad). An illustration of a nominal variable is the names of cities in the Canadian province of Alberta.

The minimum volume of the box is 48 feet³.

The volume of the empty space that needs to be filled with packing peanuts to protect the model is 32 feet³.

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume.

Given:

Pyramid base= 4 cm, height= 4 cm

So, Volume of pyramid

Answer:

A = 8a + \(\frac{1}{2}\)πa²

Step-by-step explanation:

The figure consists of a rectangle and a semi- circle

area of rectangle = 4 × 2a = 8a

area of semi- circle = \(\frac{1}{2}\)πr² ( r is the radius = a )

                                = \(\frac{1}{2}\)πa²

Then area (A ) of figure is

A = 8a + \(\frac{1}{2}\)πa² ← factor out \(\frac{1}{2}\) a from each term

   = \(\frac{1}{2}\) a(16 + aπ)

\(a(1) = 240 \\ a(2) = a(1) + d = 240 + 24 = 264 \\ a(3) = a(2) + d = 264 + 24 = 288 \\ a(4) = a(3) + d = 288 + 24 = 312 \\ a(5) = a(4) + d = 312 + 24 = 336 \\ a(6) = a(5) + d = 336 + 24 = 360\)

(b)  The value of f^(-1) is g.

(c)  The value of f ◦ f ◦ f = f ◦ (f ◦ f) is f((f ◦ f)(x)) = f((x * (x-1))*((x * (x-1)) - 1)).

According to the question

(a) To prove that f is bijective, we need to show that it is both injective (one-to-one) and surjective (onto).

Injectivity: Let x, y ∈ a such that f(x) = f(y). Then, x * (x-1) = y * (y-1). Multiplying both sides by x-1, we get x = y, meaning that f is injective.

Surjectivity: Let z ∈ a. Then, z = z * (z-1) / (z-1), which means that there exists an x ∈ a such that f(x) = z. This shows that f is surjective.

Therefore, f is bijective.

(b) To find the inverse of f, we need to find a function g: a → a such that f(g(x)) = x and g(f(x)) = x for all x ∈ a.

Consider the function g: a → a defined by g(x) = x / (x-1) for all x ∈ a.

Let x ∈ a. Then, f(g(x)) = f(x / (x-1)) = (x / (x-1)) * ((x / (x-1)) - 1) = x. Similarly, g(f(x)) = g(x * (x-1)) = x * (x-1) / (x * (x-1) - 1) = x. This shows that f and g are inverses.

Therefore, f^(-1) = g.

(c) To find f ◦ f ◦ f, we first evaluate f ◦ f and then evaluate f of the result.

Let x ∈ a. Then, (f ◦ f)(x) = f(f(x)) = f(x * (x-1)) = (x * (x-1)) * ((x * (x-1)) - 1). Hence, f ◦ f ◦ f = f ◦ (f ◦ f) = f((f ◦ f)(x)) = f((x * (x-1)) * ((x * (x-1)) - 1)).

Answer:

y=-1/4x+5

Step-by-step explanation:

perpendicular lines have slopes that multiply to -1.

Our given line:

y=4x-5

the slope (m) in it is 4. To find the slope of the perpendicular line:

4m=-1

divide by 4

m=-1/4

the slope of the new line is -1/4

here's our equation so far:

y=-1/4x+b

Since the line will pass through the point (-4,6) we can use it to solve for b (y intercept)

so substitute (-4,6) into the equation

6=-1/4(-4)+b

6=1+b

5=b

the y intercept is 5

so our equation is:

y=-1/4x+5
