the sum of 2 and y aleks

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 nurse should run the pump at 111.1 ml/hr.

To infuse a 1000ml bag of lactated ringers over 9 hours, the nurse must determine the hourly rate at which the fluid should be infused. This can be done by dividing the total volume of the fluid (1000 ml) by the number of hours it will take to infuse it (9 hours).

So, the hourly rate would be:

1000 ml ÷ 9 hours = 111.1 ml/hr.

Therefore, the nurse should run the pump at 111.1 ml/hr in order to infuse the 1000ml bag of lactated ringers over 9 hours.

By applying linear equation concept, it can be concluded that the line representing the artist whose downloads have remained constant over the month is the horizontal one, line m.

Linear equation is an equation that contains one or more variables, where each variable has the power of one.

Linear equation graph with a particular slope will be formed if this equation is depicted in a Cartesian diagram. The slope is usually called the gradient of the line (m), so the equation can be written as y = mx + c.

If the line graph is sloping to the right indicates that the gradient is positive. Conversely, if the line graph is sloping to the left indicates that the gradient is negative.

Therefore, the line representing the artist whose downloads have remained constant over the month is the horizontal one, line m.

For the given geometry the perimeter is 37 units, area is 118.55 square units and the type is pentagon.

The space enclosed by a pentagon's sides is referred to as the pentagon's area. Various techniques can be used to compute it depending on the dimensions that are known. The kind of pentagon also makes a difference. For instance, if it is a normal pentagon, the area can be determined using a single formula; but, if it is an irregular pentagon, we must divide it into various polygons and add their areas to determine the pentagon's area.

The perimeter is the sum of length of all the sides of a pentagon.

P = 5s

P = 5(7.4) = 37 units.

The area of the pentagon is given as:

A = 1/2 (P)(a)

Substitute the value of P = 37 and a = 6.4086:

A = 1/2 (37)(6.4086) = 118.55 square units.

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)

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

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.
