The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.
The area enclosed by the curve y = -x² and y = x² - i is the difference of the areas between these two curves.
To find the area enclosed by the curve y = x², we need to find its definite integral with respect to x from -∞ to ∞.
The definite integral of y = x² with respect to x from -∞ to ∞ is:
∫[-∞,∞] x² dx = (x³/3) from -∞ to ∞
Since the definite integral of an infinite function from -∞ to ∞ is undefined, we cannot find the exact value of the area enclosed by the curve y = x².
However, we can use the definite integral of y = x² - i with respect to x from -∞ to ∞ to find the area enclosed by the curve y = x² - i:
∫[-∞,∞] (x² - i) dx = (x³/3 - i * x) from -∞ to ∞
Again, the definite integral of an infinite function from -∞ to ∞ is undefined, so we cannot find the exact value of the area enclosed by the curve y = x² - i.
Since the area enclosed by the curve y = -x² is the same as the area enclosed by the curve y = x² but with the opposite sign, the difference of the areas enclosed by the two curves is equal to 56:
Area enclosed by y = x² - i - Area enclosed by y = -x² = 56
The first equation, y = -x^2, is a parabola that opens downwards.
The second equation, y = x^2 - i, is also a parabola but is translated downward by i units.
The area enclosed by the two curves will be the difference between the area under y = -x^2 and the area under y = x^2 - i.
The area under y = -x^2 can be calculated as follows:
A = ∫[-a,a] -x^2 dx = -(1/3) x^3 |^a_-a = (1/3) a^3
Where a is the x-value at which the two curves intersect.
The area under y = x^2 - i can be calculated as follows:
B = ∫[-a,a] (x^2 - i) dx = (1/3) x^3 - i x |^a_-a = (1/3) a^3 - i a
The area enclosed by the two curves is then given by:
C = B - A = (1/3) a^3 - i a - (1/3) a^3 = -i a
Since we know that the area enclosed by the curves is 56, we can set up the equation:
-i a = 56
So,
i = -56/a
Since a value is unknown, we cannot determine the exact value of i. However, we can use this equation to find the value of i for different values of a.
Therefore, The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

Consider the system modeled by the following difference equation. y(n) = 3y(n-1) + x(n − 2)
Assume the underlying system is casual with zero initial conditions. What is the transfer function?
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)
Divide by X(n) on both side, we get

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.

A house has 12 rooms (10 bedroom and 2 living rooms). We want to paint 4 yellow, 5 red and 3 purple. We do not want the living rooms to be the same color. In how many ways this can be done?
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

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]

GEOMETRY Triangle KLM is shown. Graph the image of the triangle after a dilation centered at the origin with a scale factor of 2
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).

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.

A rectangular paperboard measuring 22 in long and 18 in wide has a semicircle cut out of it to find the area of the paperboard that remains.
The area of the paperboard that remains is 268.83 square inches.
What is area?Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
Given that, a rectangular paperboard measuring 22 in long and 18 in wide has a semicircle cut out.
Area of rectangular paperboard length×width
= 22×18
= 396 square inches
Area of a semicircle = 1/2 ×πr²
Here, r=18/2 = 9 inches
= 1/2 ×3.14×9²
= 127.17 square inches
So, remaining area = 396-127.17
= 268.83 square inches
Therefore, the area of the paperboard that remains is 268.83 square inches.

Geometry worksheet. Can someone help please?
For the given geometry the perimeter is 37 units, area is 118.55 square units and the type is pentagon.
What is area of a 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.
Type: Pentagon.
Hence, for the given geometry the perimeter is 37 units, area is 118.55 square units and the type is pentagon.

Find the total surface area of this prism where the cross-section is an isosceles triangle.
Perpendicular Height: 5cm
Base Length: 24cm
Base Side Length: 10cm
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
