Integrals are mathematical representations of numbers and functions that express notions such as volume, area, displacement, and other outcomes of the combination of little data. Finding integrals is the term used to describe the procedure.

By green's theorem -

\(\int\limits^{}_{} {} \, \int\limits^{}_{a} {5dA} \, = 5/3\)

First, the integral given in this exercise corresponds to:  

\(\int\limits^{}_{C} {((3y + 7e\sqrt{x}dx) +( 8x+ 5cos(y^2)) } \, dy\)

Greens Theorem given as,

\(\int\limits^{}_{C} {(P(x,y)dx +Q(x,y)dy)} \, = \int\limits^{}_{} {x} \, \int\limits^{}_a {(-\beta /\beta _{y} )P(x,y) + (\beta /\beta _{y} )Q(x,y)} \, dA\)

and we have -

P(x,y) = 3y + \(7e^{\sqrt{x}}\)

Q(x,y) = 8x + 5cos(\(y^2\))

And,

\(\int\limits^{}_{C} {(P(x,y)dx +Q(x,y)dy)} \, = \int\limits^{}_{} {x} \, \int\limits^{}_a {5dA} \, dA\)

The value of the resistor needed in this scenario is approximately 1.2 ohms.

To find the value of the resistor in the given scenario, we can apply Ohm's Law, which states that the current (I) flowing through a resistor is directly proportional to the voltage (V) across it, and inversely proportional to the resistance (R) of the resistor.

Using Ohm's Law, we have the formula:

V = I * R

Where:

V is the voltage across the resistor (12 volts in this case),

I is the current flowing through the resistor (5 amps for each light, so a total of 10 amps),

R is the resistance of the resistor (which we need to find).

Rearranging the formula, we have:

R = V / I

Plugging in the values:

R = 12 volts / 10 amps

R = 1.2 ohms

Therefore, the value of the resistor needed in this scenario is approximately 1.2 ohms.

It's worth noting that this calculation assumes the lights are connected in parallel, as the current remains the same for each light. If the lights were connected in series, the total resistance would be the sum of the individual resistances, and the calculation would be different.

The shortest distance between the two lines L1 and L2 is 0.

The shortest distance between two lines can be found using the cross product of their direction vectors.

The direction vectors of line L1 and L2 can be found as:

L1 = B - A = (2 - 3, 1 - 2, 0 - 1) = (-1, -1, -1)

L2 = D - C = (3 - 2, 0 - 4, -2 - (-1)) = (1, -4, -3)

The cross product of the direction vectors of L1 and L2 gives the normal vector to the plane formed by the two lines:

cross(L1, L2) = (1 + 4, -1 - 4, 3 + 1) = (5, -5, 4)

The normal vector of the plane formed by the two lines, and a point on line L1 (A = (3, 2, 1)), can be used to find the equation of the plane:

5x - 5y + 4z = d

5 * 3 - 5 * 2 + 4 * 1 = d

15 - 10 + 4 = d

9 = d

So the equation of the plane formed by the two lines is:

5x - 5y + 4z = 9

The shortest distance between the two lines is equal to the distance between a point on line L1 (A = (3, 2, 1)) and the plane formed by the two lines:

d = abs(9 - (5 * 3 - 5 * 2 + 4 * 1)) / sqrt(5^2 + (-5)^2 + 4^2)

d = abs(9 - 9) / sqrt(29)

d = 0 / sqrt(29)

d = 0

Therefore, the shortest distance between the two lines L1 and L2 is 0.

Answer: To show that the function has exactly one zero in the given interval, we need to show that the function changes sign exactly once on the interval.

First, we can see that the function is continuous on the interval (0, pi/2) as it is a polynomial of trigonometric functions.

Next, we can evaluate the function at the endpoints of the interval:

R(0) = sec^2(0) - cos(0) - 1 = 1 - 1 - 1 = -1

R(pi/2) = sec^2(pi/2) - cos(pi) - 1 = undefined

We can see that R(0) is negative, and since the function is continuous on the interval, by the Intermediate Value Theorem, the function must pass through zero at some point in the interval.

To show that it passes through zero only once, we can take the derivative of the function:

R'(theta) = 2sec^2(theta)sin(theta) + 2sin(2theta)

We can see that R'(theta) is positive for all theta in the interval (0, pi/2), as sec^2(theta) and sin(theta) are positive and sin(2theta) is non-negative. Therefore, the function R(theta) is strictly increasing on the interval, and can cross the x-axis at most once.

Thus, we have shown that the function R(theta) has exactly one zero in the interval (0, pi/2).

The expression 2(3+4) can be expressed as 2×7

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

For example the factors of 8 are 1,2,4,8. i.e 1×8=8, 2×4= 8

considering the expression 2(3+4), the value is 2(7)= 14

Therefore the expression can be expressed as product of two factors (2 and 7) as 2×7.

Hello. This question is incomplete. The full question is:

There is a harvest festival each year on the planet Bozone. During that time, most of the Bozone residents sit down to rejoice and eat roast snig. Past history shows that a reasonable price-demand equation is:

p=300−4x where x is the number of kilograms of snig sold, and p is the price per kilogram of snig in the local currency, the Bozat.  

To sell an additional kilogram of snig, how much does the price need to decrease?   Price needs to decrease by  Bozats.

Answer:

It is necessary to decrease 4 bozats in the price so that an additional 1 kq of snig can be sold.

Step-by-step explanation:

You can achieve this result through a very simple and straightforward calculation.

First it is necessary that you assume the equation (x + 1) for X. This way you will have the mathematical expression:

300-4 (X + 1) = 300-4x-4.

The coordinates of L are: (8,-4)

Here, triangle is rotated 270° counterclockwise. So the rule that we have to apply here is

(x, y) → (y, -x)

Based on the rule given in step 1, we have to find the vertices of the rotated figure.

(x, y) → (y, -x)

L(4,8) → L'(8.-4)

M(4,3) → M'(3,-4)

N(8,8) → N'(8,-8)

Vertices of the rotated figure are:

L'(8.-4)  M'(3,-4)  N'(8,-8)

Hence we get the desired result.

Answer:   5/8

Step-by-step explanation:

Answer:

The probability is 5/8

Step-by-step explanation:

First, we must add all the numbers together. 5 + 8 + 7 + 4 = 24. Now, let's add the white balls and green balls. 5 + 4 = 9. Therefore, the probability of choosing a white or green ball is 9/24 which also equals 3/8. To find out the probability of NOT choosing white or green, we must subtract 9 from 24. 24 - 9 = 15. So, the probability of choosing neither the white or green balls equals 15/24 which also equals 5/8.

The new coordinates of the reflected point will be (2, 2).

In mathematics, reflection is a transformation that "flips" an object over a line or plane. Reflection is a type of symmetry, where an object appears exactly the same after being reflected as it did before.  

When a point is reflected across the y-axis, its x-coordinate changes sign while its y-coordinate remains the same.  

Here we have

The point (-2, 2) is reflected across the y-axis

When a point is reflected across the y-axis, its x-coordinate changes sign while its y-coordinate remains the same.

The new coordinate of the point = (-(-2), 2) = (2, 2)

Therefore,
