which type of unit cell has a coordination number of 12?

Answer:

Step-by-step explanation:

620 cm^2

Step-by-step explanation:

Area of isosceles triangles:

A = (b×h) ÷ 2

Substitute

(24 × 5) ÷ 2

120 ÷ 2 = 60 cm^2

There are 2 triangles so:

60 × 2 = 120 cm^2

Area of 2 identical rectangles:

- They are identical and this is shown by the two short lines which indicate that this is an isosceles triangle. They have 2 identical sides.

A = L × W

Substitute

10 × 13 = 130

Because there are two:

130 × 2 = 260 cm^2

Area of the rectangle at the bottom:

- Let's not forget the rectangle at the bottom of this shape.

A = L × W

Substitute

24 × 10 = 240 cm^2

Add these all together to get the total surface area:

120 + 260 + 240 = 620 cm^2

Answer: 620 cm^2

Answer:

620cm squared

Step-by-step explanation:

a=bxh/2

so this means

24x5/2=area of one triangle(60cm squared)

since there are two .that means the area for both triangles is 120cm squared

for the recatngles:

a=lxw

Substitute

10 × 13 = 130

since there are 2 of them,

130 × 2 = 260 cm^2

the rectangle on the bottom:

a=lxw

24x10=240cm squared

240+260+120=620

Check the picture below.

Total number of ways to paint rooms is 19,740.

We can solve this problem using the combinatorics. First, we choose the color for the living rooms, which can be done in 3*2 = 6 ways (yellow, red, or purple). Then, we choose the colors for the remaining 10 rooms.

Case 1 : living room is yellow and red

Then remaining colors are 3 yellow, 4 red, 3 purple

number of ways to paint living room = 2

number of ways to pain bedroom = 10!/(3! 4! 3!)

So number of ways = 2 * 10!/(3! 4! 3!) = 8400

Case 2 : living room is yellow and purple

Then remaining colors are 3 yellow, 5 red, 2 purple

So number of ways = 2 * 10!/(3! 5! 2!) = 5040

Case 3 : living room is red and purple

Then remaining colors are 4 yellow, 4 red, 2 purple

So number of ways = 2 * 10!/(4! 4! 2!) = 6300

Total number of ways = 8400 + 5040 + 6300 = 19,740

When ΔKLM is dilated with a scale factor of 2 the new ΔK'L'M' has vertices K'(4,10), L'(8,4) and M'(4,4).

What is dilation?

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial shape should be stretched or contracted during a dilatation.

The ΔKLM has the coordinates of vertices - K(2,5), L(4,2) and M(2,2)

If the scale factor is 2, then every coordinate point of the original triangle is multiplied by the scale factor 2.

When the triangle is dilated with the scale factor of 2, the coordinate points formula becomes -

(x,y) → (2x,2y)

So, obtain the new triangle ΔK'L'M' -

K(2,5) → [2(2),2(5)] → K'(4,10)

L(4,2) → [2(4),2(2)] → L'(8,4)

M(2,2) → [2(2),2(2)] → M'(4,4)

The graph for the new coordinates have been ploted.

Therefore, the new coordinates are K'(4,10), L'(8,4) and M'(4,4).

The equation for a hydraulic lift can be used to calculate the force on each mass.  F1 = F2

m2 = 210 kg

Using the equation for a hydraulic lift, the force on each mass can be calculated.

F1 = F2

(m1 x g) x (d1/d2) = (m2 x g)

(70 kg x 9.8 m/s2) x (1.0 m/3.0 m) = (m2 x 9.8 m/s2)

210 kg = m2 x 9.8 m/s2

m2 = 210 kg/9.8 m/s2

m2 = 21.43 kg

m2 = 210 kg (rounded up)

The equation for a hydraulic lift can be used to calculate the force on each mass.  F1 = F2

Assuming the underlying system is casual with zero initial conditions, the transfer function is Y(z)/X(n) = 1/([tex]z^2[/tex] - 3z).

The differential equation is y(n) = 3y(n-1) + x(n − 2).

Since there are no initial conditions, the underlying system is known to be casual.

Considering the Transfer function.

Z transform properties are used

y(n-1) = [tex]z^{-1}[/tex]Y(z)

y(n) = Y(z)

x(n-2) = [tex]z^{-2}[/tex]X(n)

Now putting the value in the equation

Y(z) = 3[tex]z^{-1}[/tex]Y(z) + [tex]z^{-2}[/tex]X(n)

Multiply by [tex]z^2[/tex] on both side, we get

[tex]z^2[/tex]Y(z) = 3zY(z) + X(n)

Subtract Y(z) 0n both side, we get

[tex]z^2[/tex]Y(z) - 3zY(z) = X(n)

Y(z)([tex]z^2[/tex] - 3z) = X(n)

Divide by ([tex]z^2[/tex] - 3z) on both side, we get

Y(z) = X(n)/([tex]z^2[/tex] - 3z)

The solution to x, when the equations au = a and av =b are satisfied, will be x = [0 0].

Given that u = [2 -3] and v = [4 2] satisfy the equations au = a and av = b, we need to find a solution to the equation ax = b.

Let's express the matrix an as a column vector of its columns: a = [a1 a2]. Now, we have the following equations:

a*u = a

[a1 a2] * [2 -3] = [a1 a2]

This yields two equations:

2a1 - 3a2 = a1

2a1 - 3a2 = a2

Simplifying these equations, we get:

a1 = 3a2 ...(1)

a2 = 2a1 ...(2)

Substituting equation (2) into equation (1), we have:

a1 = 3(2a1)

a1 = 6a1

Solving for a1, we find a1 = 0.

Substituting this value back into equation (2), we have:

a2 = 2(0)

It is ensured that the sample size is less than 10% of the population size when creating a confidence interval for a population proportion. This requirement is crucial because observations are more likely to be independent when the sample size is smaller than the population size. Calculating the distribution's standard deviation is impossible if this condition is not satisfied. The standard deviation of the distribution cannot be appropriately calculated if this condition is not satisfied. The confidence level will be incorrect if the standard deviation is incorrect. Population parameters are less likely to be found in a confidence interval. As a result, the capture rate will be lower than what the confidence level predicts.

Step-by-step explanation:

Information we must know:

1) Find the area of the circle

2) Find the area of the square around the circle

3) Subtract!

Have a lovely day :)

Answer:

3.4 in²

Step-by-step explanation:

We can solve for the area of the blue portion of this figure by subtracting the area of the circle (the area that is NOT blue) from the area of the surrounding square.

First, we can solve for the area of the square using arithmetic.

In this problem, the side length is twice the radius ([tex]r[/tex]) of the circle (given as 2 in), since the circle is circumscribed inside the square, meaning that it touches the square at all 4 midpoints of its sides.

[tex]\textrm{side length} = 2r[/tex]

[tex]\textrm{side length} = 2(2 \, \textrm{in})[/tex]

[tex]\textrm{side length} = 4 \, \textrm{in}[/tex]

Now we can solve for the area of the square using the formula:

[tex]\textrm{Area}_\square = \textrm{side length}^2[/tex]

[tex]\textrm{Area}_\square = (4 \, \textrm{in})^2[/tex]

[tex]\textrm{Area}_\square = 16 \, \textrm{in}^2[/tex]

Next, we can solve for the area of the circle using the formula:

[tex]\textrm{Area}_\circ = \pi r^2[/tex]

Remember that the radius of the circle was given as 2 in.

[tex]\textrm{Area}_\circ = \pi (2 \, \textrm{in})^2[/tex]

[tex]\textrm{Area}_\circ = 4\pi \, \textrm{in}^2[/tex]

Finally, we can solve for the area of the blue portion of the figure by subtracting the area of the circle from the area of the square.

[tex]\textrm{Area}_{\textrm{blue}} = A_\square - A_\circ[/tex]

[tex]\textrm{Area}_{\textrm{blue}} = 16 \, \textrm{in}^2 - 4\pi \, \textrm{in}^2[/tex]

If we plug this into a calculator, we approximately get:
