The flux of the vector-field F = 1i + 1j + 3k across the surface S is 2. We find out the flux of the vector-field using Green's Theorem.

Flux form of Green's Theorem for the given vector-field

φ = ∫ F.n ds

= ∫∫ F. divG.dA

Here G is equivalent to the part of the plane = 2x + 1y + z = 2.

and given F = 1i + 1j + 2k

div G = div(2x + 1y + z = 2) = 2i + 4j + k

Flux = ∫(1i + 1j + 3k) (2x + 1y + z) dA

φ = ∫ (2 + 4 + 2 ) dA

= 8∫dA

A = 1/2 XY (on the given x-y plane)

2x+4y =2

at x = 0, y = 1/2

y = 0, x = 1

1/2 (1*1/2) = 1/4

Therefore flux = 8*1/4 = 2

φ = 2.

68.26% of students out of 500 would score between 68 and 82  if the mean is 75 and standard deviation is 7.

A low standard deviation suggests that values are often close to the mean (also known as the anticipated value) of the collection, whereas a large standard deviation suggests that values are dispersed over a wider range.

Standard deviation, often known as SD, is most frequently represented in mathematical texts and equations by the lower case Greek letter (sigma), for the population standard deviation, or the Latin letter s, for the sample standard deviation.

Given,

Mean μ=75

σ=7

By using normal distribution,

P(68<x<82)=P(((68-μ)/σ)<z<((82-75)/7))

P(-1<z<1)

P(z<1)-P(z< -1)

By using z-table, we get

=0.8413-0.1587

=0.6826

P(68<x<82)=0.6826≈68.26

P(68<x<82)=68.26%

Therefore, 68.26% of students out of 500 would score between 68 and 82 if the mean is 75 and standard deviation is 7.

The measurement of <B is 121 degree.

The sum of a triangle's three internal angles is 180 degrees, as stated by the angle sum Property of a triangle.

According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees.

Given:

let the measure of <A be x.

So, m<G= x- 9

and, m<B = 4x- 15

Using Angle Sum Property

m<A+ m<B+ m<G= 180

x+ 4x- 15 + x- 9 = 180

6x - 24 = 180

6x = 180+ 24

x= 204/6

x= 34

So, m<A = 34

m<B= 4(34) - 15 = 121

and, m<G = 34 - 9= 25 degree.

Hence, the measure of <B is 121 degree.

The inverse function [tex]f^{-1}[/tex](8) = 3/2

A function that "undoes" another function is known as an inverse in mathematics. In other words, if f(x) produces y, then introducing y into the inverse of f produces x. An invertible function has an inverse, which is represented by the symbol.[tex]f^{-1}[/tex]

The function given is

f(x) = 2x + 5

We have to find the inverse

Let us consider f(x) as y

y = 2x + 5

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. The equation of a line that is perpendicular to Y = -3x^2 is: X = -3y^2/2

The equation of a line that is perpendicular to a given line is found by changing the sign of the slope of the given line and taking the reciprocal of the slope.

The slope of the given line Y = -3x^2 is -3, so the slope of the line perpendicular to it is 3.

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Therefore, the equation of a line that is perpendicular to Y = -3x^2 is: x = 3y + b

We can now solve for the y-intercept, b, by substituting the point (0,0) into the equation:

x = 3y + b

0 = 3(0) + b

b = 0

The probability that in the resulting coloring, no two adjacent edges have the same color is 1/24.

It is given that the edges of a regular pentagon are colored res, blue or green at random, so that each edge has an equally likely chance of being painted with any color.

So you can't have 0 reds.

You can have 1 red and there are 2 scenarios for that.

You can have 2 reds and there are 8 scenarios for that.

You can't have 3+ reds.

In total there are 10 scenarios that work.

Therefore there are 3⁵ - 3 total cases.

i.e there are 240 total cases.

So the probability that no two adjacent edges have the same color is,

total scenarios/total cases = 10/240 = 1/24.

A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean. The standard deviation measures the degree of dispersion of a set of data. Each data point is compared to the average of all the data points, and standard deviation gives a determined value that indicates whether the data points are clustered together or dispersed. The standard deviation of a normal distribution indicates how far values deviate from the mean.

Answer:

To solve this equation, we can first rewrite it in a form that is easier to work with. We can do this by dividing both sides by 9^2, which gives us:

(9^2x+1)/9^2 = 27^x-3

We can then simplify the left side of the equation by taking the square root of both sides, which gives us:

3x+1/3 = 3^x-3

We can then rearrange the terms on the left side of the equation to get:

3x = 3^x-6

We can then subtract 3^x from both sides of the equation, which gives us:

3x-3^x = -6

We can then divide both sides of the equation by 3-3^x, which gives us the final solution:

Therefore the directional derivative of f at a in the direction of the vector ad is grad F( x, y ) ×ad(u)  =64/10

Any function's rate of change at a given location in a fixed direction is known as its directional derivative. Any derivative is thought of in this way: as a vector form. It provides information on the function's immediate rate of variation.

Here,

The terms "directional derivative" and "gradient of a function" must be used in order to respond to this question.

Grad F(x, Y) = 64/10 ad(u)

A function's gradient is a vector with the following definitions:

Grad f(x,y) is equal to f(x,y)/x I + f(x,y)/y j.

where the definition of the directional derivative in the direction of ab is

Grad f(x,y) = Uab(u), where Uab is a unitary vector pointing in the direction of ab.

Consequently, Uab (u) = Uab/|ab|

If f (x,ydirectional )'s derivative in the direction of vector ab is 5, then.

A (7, 3), B (12, 3), and vector ab is then:

ab = [ 12 - 7 , 3 - 3 ] ⇒ ab = [ 5 , 0 ] as well as |ab| = (5)2 (0)2 |ab| = 5

a unitary vector in the direction of ab is:

ab(u) = 5×i/ 5 and according to equation (1)

δf(x,y) / δx × i  × 5 × i / |5| = 5

δf(x,y) / δx × i  × 5 × i = 25

δf(x,y) / δx = 5       then   f( x,y ) = 5 × x  + ????

We go on to calculate the component on j of f(x,y)

Following the same procedure

ac = ( 7 , 7 ) - ( 7 , 3 )     ⇒   ac = [ 0 ,  4 ]      |ac| = √(4)² + (0)²

|ac| = 4

In the direction of ac(u), the unitary vector is:

ac/|ac| = 4 × j / 4

Then :

j / 4 + f(x,y) / y = 4

16 is equal to f(x,y) / y j + 4 j.

both f(x,y) = -4y & f(x,y) / y = - 4

f(x,y) = 5 × I + 4 × j

Finally:

((15 - 7, 9 - 3)) as the vector ad ⇒ ad = ( 8 , 6 ) ( 8 , 6 )

a unitary vector in the direction of

ad(u) = (8 ×i + 6 ×j) / √ (8)² Plus (6)

² ⇒ ad(u) = (8 ×i + 6 ×j) /√ (8)² + (6) ²

ad(u) = (8 ×i + 6 ×j) /10

Currently, we have f (x, y) = 5 I + 4 j and ad(u) = 8 I + 6 j /10.

We can calculate the directional derivative of f(x,y) in the direction of ad with the use of equation (1)

grad F( x, y ) ×ad(u)  = ( 5 × i + 4 × j ) × ( 8 ×i  + 6 ×j ) /10

grad F( x, y ) ×ad(u)  = 4 + ( 24/10)

grad F( x, y ) ×ad(u)  =64/10
