Answer:
Step-by-step explanation:
if it's talking about between the numbers 75 to 97, then it's 22.
How
do you integrate this equation?
32 rx-x-5 dx = +2 o (A) 条 10 - +30m: 及 25 21 (B)
The integration of the equation \(32 rx - x - 5 dx = +2 o (\)A) 条 10 - +30m: 及 25 21 (B) can be done as follows:
\(∫(32rx - x - 5)dx = 2(A)条10- + 30m: 及 25 21(B)\)
To integrate the equation, we use the power rule of integration, which states that ∫x^n dx = (x^(n+1))/(n+1), where n is any real number except -1.
Applying the power rule, we integrate each term of the equation separately:
\(∫32rx dx = 16r(x^2)/2 = 16rx^2\)
∫x dx = (x^2)/2
∫5 dx = 5x
Now we substitute the integrated terms back into the original equation:
\(16rx^2 - (x^2)/2 - 5x = 2(A)条10- + 30m: 及 25 21(B)\)
The resulting equation is the integration of the given equation.

the two plates of a capacitor hold 2500 μc and –2500 μc of charge, respectively, when the potential difference is 960 v. what is the capacitance?
2.6 * 10⁻⁶ F is the capacitance.
What is a capacitor short answer?
A capacitor is a component used in electrical circuits to hold charges. The idea behind how a capacitor functions is that when an earthed conductor is moved close to a conductor, its capacitance increases noticeably.
As a result, a capacitor contains two plates with equal and opposing charges that are spaced apart. Two conductors that are near to one another and are isolated from one another make up a capacitor, a device for storing electrical energy. The parallel-plate capacitor is a straightforward illustration of such a storage device.
We have realtion Q=CV

A line and a point are coplanar.2. Congruent angles form vertical angles.3. Linear pair that are congruent are rightangles.4. The sum of angles that formed linear pairis less than 180'.5. Vertical angles are complementary.
The given statement is 1. Always true
2. Always true
3. Always true
4. Sometimes true
5. Never true
Statement 1: A line and a point are always coplanar.
Answer: Always true.
Reason: This statement is always true because a line and a point can always be found on the same plane. In Euclidean geometry, a plane is a flat surface that extends infinitely in all directions, and any two points on the plane can be connected by a straight line. Therefore, a line and a point will always lie on the same plane.
Statement 2: Congruent angles form vertical angles.
Answer: Always true.
Reason: Vertical angles are formed by the intersection of two lines. When two angles are congruent, it means they have the same measure. If two angles have the same measure and are formed by the intersection of two lines, then they are vertical angles. Therefore, congruent angles always form vertical angles.
Statement 3: Linear pairs that are congruent are right angles.
Answer: Always true.
Reason: A linear pair consists of two adjacent angles that share a common side and form a straight line. If the two angles of a linear pair are congruent, it means they have the same measure. In Euclidean geometry, a straight angle measures 180 degrees. If two angles in a linear pair are congruent and their measures add up to 180 degrees, then each angle must measure 90 degrees, which is the measure of a right angle. Therefore, linear pairs that are congruent are always right angles.
Statement 4: The sum of angles that form a linear pair is less than 180 degrees.
Answer: Sometimes true.
Reason: The sum of angles that form a linear pair is always equal to 180 degrees, not less than 180 degrees. This is based on the definition of a linear pair, which states that the two angles in a linear pair are supplementary, meaning their measures add up to 180 degrees. However, if the statement said "less than or equal to 180 degrees," then it would be always true.
Statement 5: Vertical angles are complementary.
Answer: Never true.
Reason: Vertical angles are not complementary. Complementary angles are two angles that add up to 90 degrees. Vertical angles, on the other hand, are a pair of non-adjacent angles formed by the intersection of two lines. They do not necessarily have any specific relationship to each other in terms of their angle measures. Therefore, vertical angles are not complementary by definition.

Suppose the following equations describe a scenario involving an externality: MSB=MPB=12−0.5Q
MSC=2+1.5Q
MPC=2+0.5Q
1. What kind of externality (positive or negative) is this? How do you know? 2. Sketch a graph of the marginal cost and benefit curves for this scenario. 3. Compute the quantity that will result from private decision-making. Show your work. 4. Compute the quantity that would be best from society's viewpoint. Show your work. 5. How do the social and private optima compare? Why is this the expected result in the presence of this type of externality?
The presence of a negative externality causes the MSC to be higher than the MSB, which leads to the market over-producing the good. This is because producers are only taking their private costs and benefits into account, not the costs and benefits to society as a whole. The difference between the private and social optima is known as the deadweight loss. In this case, the deadweight loss is equal to the shaded triangle in the attached image.
1. This is a negative externality. We can see this by the MSC being higher than the MSB. This means that the cost to society of producing the good is higher than the benefit to society, resulting in the market over-producing the good.2. See the attached image. 3. At private decision making, we set the MSB equal to the MPC: 12-0.5Q = 2+0.5Q. Solving for Q gives Q = 8. 4. To find the socially optimal quantity, we need to set MSB equal to MSC: 12-0.5Q = 2+1.5Q.

Drag the labels into place in the figure for a market leaving, and then returning to, equilibrium as firms exit after a decrease in demand. original short-run supply* final short-run demand* original short-run demand* long-run supply* final short-run supply* Drag each item above to its appropriate location in the image. Note that every item may not have a match, while some items may have more than one match. Price P2 +--- Q3 Q2 Q2 Market quantity (Q)
The original short-run supply curve shifts left, causing the market price to decrease to P2 and the quantity to decrease to Q2.
As a result, some firms exit the market, causing the short-run supply to shift back to the right and the market to return to equilibrium at a lower quantity, Q3, and the same price, P2.
When demand decreases, the original short-run supply curve shifts leftward as firms reduce production to meet the lower demand. This causes the market price to decrease to P2 and the quantity to decrease to Q2.
At this lower price, some firms may exit the market if they are unable to cover their costs, causing the short-run supply curve to shift back to the right.
As a result, the market quantity decreases further to Q3, and the market returns to equilibrium at the same price, P2. In the long run, the supply curve may shift further to accommodate the lower demand, resulting in a new equilibrium price and quantity.

Answer:
Right triangle
Step-by-step explanation:
we are given three sides as 14 ft, 48 ft, and 50 ft
Firstly, we will verify for right angle
We know that any triangle is right angled when it satisfies Pythagoras theorem
We know that hypotenuse side value is always largest
so, hypotenuse=c=50
Let's assume other two sides as
a=14
b=48
now, we can use Pythagoras theorem formula
C²=a²+b²
we can plug values and we check whether left side is equal to right side
50²=14²+48²
2500=196+2304
2500=2500
we can see that left side is equal to right side
Since, it satisfies Pythagoras theorem

a norman window is constructed by adjoining a semicircle to the top of an ordinary rectangular window (see figure). find the dimensions of a norman window of maximum area if the total perimeter is 14 feet.
The dimensions of a norman window of maximum area if the total perimeter is 14 feet are 2 ft and 4 ft respectively.
Given:
a norman window is constructed by adjoining a semicircle to the top of an ordinary rectangular window
we are asked to find the dimensions of a norman window of maximum area if the total perimeter is 14 feet.
the area of the semicircle is given by:
A = πr²/2
The area of the rectangle is just the product of its length and width.
Letting A be the area of the window and adding the two ares, we have:
A = xy + π(y/2)²/2
= xy + π(y²/4)/2
= xy+πy²/8
we know the circumference = πd
the circumference of a semicircle is half of that. The perimeter of a rectangle is the sum of twice the length and twice the width. However, one of the sides is replaced by the semicircle, so we remove it from the equation.
Hence, we have the following equation for the perimeter.
14 = 2x+y+πy/2
let us isolate x from this equation
14 = 2x+y+πy/2
14-y-π/2 = 2x
x = 7-y/2-πy/4
substituting x to the equation for the area, w have:
A = xy + πy²/8
= (7 - y/2 - πy/4)y + πy²/8
= 7y - y²/2 - πy²/4 + πy²/8
= 7y - y²/2 - 2πy²/8 + πy²/8
= 7y - y²/2 - πy²/8
differentiating A with respect to x.
A = 7y - y²/2 - πy²/8
A' = 7 - y - πy/4
⇒ 7 - y - πy/4 = 0
⇒ 28 - 4y - πy=0
⇒ 28 = 4y+πy
⇒ 28=(4+π)y
⇒ y = 28/4+π ≈ 4 ft
perimeter:
14 = 2x+y+πy/2
14 = 2x + 28/4+π + π(28/4+π)/2
14(8+2π)=2x(8+2π)+28(2)+28π
112+28π = 16x+4πx+56+28π
112-56=16x+4πx
56=(16+4π)x
x=56/16+4π
= 14/4+π
x=14/4+π≈ 2 ft.
Hence the dimension are 2 ft and 4 ft.
