Step-by-step explanation:

A dilation is a transformation which generates an image that is the same shape as the original object but in a different size.

The image can be obtained by multiplying the measure of the original object by a scale factor.

If the scale factor > 1, the image is stretched

If the scale factor < 1, the image is reduced

If the scale factor = 1, the image and object will be congruent

For example, if we multiply the measure of the coordinates of the vertex A(2, 2) of a triangle by a scale factor of 2, the image A' is stretched as the scale factor > 1.

Dilation with scale factor 2, multiply by 2.

A(2, 2) → (2(2), 2(2)) = A'(4, 4)

So, the image point A'(4, 4) is enlarged.

Dilation with scale factor ½, multiply by ½.

A(2, 2) → (2(1/2), 2(1/2)) = A'(1, 1)

So, the image point A'(1, 1) is reduced.

Therefore, we conclude that:

By using the fact that the internal angles of a triangle always add up to 180°, we will see that x = 100°.

Remember that the sum of all the internal angles of a triangle is always equal to 180°.

On the image we can see two triangles, let's define the angle at the right as A. and the angle at the left as B

We can write:

A + B + x = 180°

And for the inner triangle the angles give:

A/2 + B/2 + 140° = 180°

So we have a little system of equations:

A + B + x = 180°

A/2 + B/2 + 140° = 180°

If we multiply the second equation by 2 we get:

A + B + 280° = 360°

With the first equation we can write:

A + B = 180° - x

And replace that in the above equation

(A + B) + 280° = 360°

180° - x + 280°  = 360°

Now we can solve this to get the value of x:

180° + 280° - 360° = x = 100°

We conclude that the measure of angle x is 100°

Answer:

Step-by-step explanation:

14a+2=14+2+a=16a.

Answer:

b = 10.06 in

Step-by-step explanation:

Formula we use,

→ (AC)² = (BC)² + (AB)²

Now the value of a will be,

→ (10.5)² = b² + (3)²

→ 110.25 = b² + 9

→ b² = 110.25 - 9

→ b = √101.25

→ [ b = 10.06 in ]

Hence, value of b is 10.06 in.

The size of the larger cell is \(5.7 * 10^{-3}m\)

The size of the cell is given:

\(Cell = 4.75 * 10^{-7}m\)

The larger cell is:

\(Larger = 1.2 * 10^{4} * Cell\)

So, we have:

\(Larger = 1.2 * 10^{4} * 4.75 * 10^{-7}m\)

Rewrite as:

\(Larger = 1.2 * 4.75 * 10^{4} * 10^{-7}m\)

Evaluate the product

\(Larger = 5.7 * 10^{-3}m\)

Hence, the size of the larger cell is \(5.7 * 10^{-3}m\)

The number is written in the form a*b^10 ,where we have 1<a<10

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

The height of the statue of Abraham Lincoln memorial in Washington, DC  is 5.7912 m.

We can rewrite it as:

5.7912 ≈ 6

Q1. p=a-i

Q2. l= 1/2p-w

Q3. t=d/s

I think that these are correct

Step-by-step explanation:

the coordinates of a point are x and y.

so, by using the coordinates of each point in the main equation we get 2 specific equations to solve for the 2 variables A and B.

for (-3, 10) we get

A×-3 + B×10 = -18

for (6, -2) we get

A×6 + B×-2 = -18

when I look at these 2 equations and the multiplication factors of A and B in them, I find we can multiply the first equation by 2 and then add both equations. that eliminates A and we can solve for B :

A×-6 + B×20 = -36

+ A× 6 + B×-2 = -18

-------------------------------

0. B×18 = -54

B = -54/18 = -3

A×6 + -3×-2 = -18

A×6 + 6 = -18

A×6 = -24

A = -24/6 = -4

After calculating the partial derivatives and the cross product, we can find the double integral of the magnitude over the region (0 ≤ r ≤ √3, 0 ≤ θ ≤ 2π). This double integral gives the surface area of the part of the plane inside the cylinder.

To find the area of the surface of the part of the plane x + 2y + 3z = 1 that lies inside the cylinder x^2 + y^2 = 3, we can use a parametric representation for the plane and cylinder intersection.

Let x = r * cos(θ) and y = r * sin(θ), where r^2 = 3 (from the cylinder equation). Now, we can find z in terms of r and θ using the plane equation:

z = (1 - x - 2y) / 3
z = (1 - r * cos(θ) - 2r * sin(θ)) / 3

Now, we have the parametric representation of the intersection: (r * cos(θ), r * sin(θ), (1 - r * cos(θ) - 2r * sin(θ)) / 3). To find the surface area, we need to calculate the partial derivatives with respect to r and θ and then find the magnitude of the cross product.

True. Recursion is often necessary to solve certain types of problems that exhibit a recursive structure or require repeated subproblem solving.

Recursion is a programming technique where a function calls itself in its own definition. It allows for the decomposition of complex problems into smaller, more manageable subproblems that can be solved recursively. Recursion is particularly useful when problems exhibit a recursive structure, such as tree traversal, backtracking, or divide-and-conquer algorithms.

For example, problems like computing the factorial of a number, calculating Fibonacci numbers, or traversing a binary tree can be elegantly and efficiently solved using recursion. These problems can be broken down into smaller instances of the same problem until a base case is reached, and then the solutions are combined to solve the original problem.

However, it's worth noting that not all problems require recursion for their solution. There are alternative approaches, such as iterative loops or dynamic programming, which can be used depending on the problem's characteristics and requirements.
