Answer 1

The double integral flux is -72π.

We can parameterize the cone as follows:

x = r cosθ

y = r sinθ

z = z

where r is the distance from the z-axis and θ is the angle of rotation around the z-axis.

Then we can calculate the normal vector as follows:

n = (∂x/∂r × ∂y/∂θ)i + (∂y/∂r × ∂x/∂θ)j + (∂z/∂r × ∂z/∂θ)k

= (-r cosθ)i + (-r sinθ)j + (6r/(2√(x^2+y^2)))k

= -r(cosθ i + sinθ j) + 3k/√(x^2+y^2)

Taking the dot product of F with n, we get:

F · n = (5xy)i - 2zk · [-r(cosθ i + sinθ j) + 3k/√(x^2+y^2)]

= -2z(3/√(x^2+y^2)) = -6z/r

Then the flux integral becomes:

double integral_S F · n dS = ∫∫(-6z/r) r dr dθ dz

where the limits of integration are

0 ≤ θ ≤ 2π

0 ≤ z ≤ 6

0 ≤ r ≤ 6√(z^2/36 - 1)

Evaluating the integral, we get:

∫∫(-6z/r) r dr dθ dz = -72π

Therefore, the flux is -72π.

Answer 2

Using the binomial series formula. The first four terms of the MacLaurin series for 7√(1 + x) are:

7 + (7/2)x - (7/16)x^2 + (21/256)x^3

(a) Using the binomial series formula, we have:

1/(1 + x)^8 = (1 + x)^(-8)

= 1 + (-8)x + (-8)(-9)/2! x^2 + (-8)(-9)(-10)/3! x^3 + ...

Therefore, the first four terms of the MacLaurin series for 1/(1 + x)^8 are:

1 - 8x + 36x^2 - 56x^3

(b) Using the binomial series formula, we have:

7√(1 + x) = 7(1 + x)^(1/2)

= 7(1 + (1/2)x + (-1/8)x^2 + (1/16)x^3 + ...)

Answers

Answer:

the fraction of the invitations considered to be an animal on them is [tex]\frac{3}{7}[/tex]

Step-by-step explanation:

The computation of the fraction of the invitations considered to be an animal on them is shown below:

= Children party invitations × animal on them

Solve by elimination:
9x + 4y = 97
9x + 6y = 123
14
15'
B (5, 13)
(13,5)
D (1, 22)

Answers

Answer:

B (5, 13)

Step-by-step explanation:

9x + 4y = 97

9x + 6y = 123

To solve by elimination, we want to eliminate a variable. To do this, we must make one variable cancel out.

First, we can see that both equations have 9x. To cancel out x, we must make one of the 9x's negative. To do this, multiply each term in the equation by -1.

-1(9x + 6y = 123)

-9x - 6y = -123

This is one of your equations. Set it up with your other given equation.

9x + 4y = 97

-9x - 6y = -123

Imagine this is one equation. Since every term is negative, you will be subtracting each term.

9x + 4y = 97

-9x - 6y = -123

___________

0x -2y = -26

-2y = -26

To isolate y further, divide both sides by -2.

y = 13

Now, to find x, plug y back into one of the original equations.

9x + 4(13) = 97

Multiply.

9x + 52 = 97

Subtract.

9x = 45

Divide.

x = 5

Check your answer by plugging both variables into the equation you have not used yet.

-9(5) - 6(13) = -123

-45 - 78 = -123

-123 = -123

Your answer is correct!

Step-by-step explanation:

We have the expression 2x + 5xy + 9x + 3 and are asked the solution.

This is different from most standard addition problems, we have an influx of variables, since we do. We follow the like term rules, which is that we can only add the numbers that have the same variable endings, in this case, only 2x and 9x are like terms, so we add them.

2x + 9x

11x

Therefore :

How do you solve for x and y?

Answers

Answer:

x = 100, y = 50

Step-by-step explanation:

Make a system of equations:

First, you know that x + y degrees and 30 degrees are on a line together, they add up to 180 degrees:

x + y + 30 = 180

x + y = 150

Next, the interior angles of a triangle always add up to 180 degrees, and since 2y, x/2, and 30 are all the angles in a triangle, you have:

2y + x/2 + 30 = 180

x/2 + 2y = 150

Now, all you have to do is solve the system of equations.

To start, multiply the second equation by 2 to get rid of the fraction:

x + 4y = 300

Then, you can subtract the two equations:

x + 4y = 300

- (x + y = 150)

3y = 150

divide both sides by 3

y = 50

substitute y = 50 into the equation x + y = 150:

x + 50 = 150

x = 100

Height = perpendicular distance of AB from vertex X
