Let's start by finding the surface area of the parametric surface given by

To find the surface area, we need to evaluate the integral:

where

The surface area can be expressed in terms of a double integral over the parameter domain of the surface, which is the square [0,1] × [0,1]:

First, we need to compute the partial derivatives:

Then, we can compute the cross product:

Finally, we can compute the magnitude of the cross product:

Thus, the surface area of the parametric surface given by

is

Now, to find the surface area of the parametric surface given by

we can use the same method. The partial derivatives are:

The cross product is:

And the magnitude of the cross product is:

Thus, the surface area of the parametric surface given by

is

Therefore, the surface area of the second parametric surface is 2 times the surface area of the first parametric surface, which is 2.

The given parametric surface has a surface area given by 2π.

To find the surface area of the parametric surface given by  with , we need to use the formula for the surface area of a parametric surface:

A = ∫∫ ||(∂f/∂u) x (∂f/∂v)|| dudv

where ||(∂f/∂u) x (∂f/∂v)|| is the magnitude of the cross product of the partial derivatives of the parametric equations, and dudv is the area element in the u-v plane.

For the given parametric surface, we have:

x = u
y = v
z = uv

So, the partial derivatives are:

∂f/∂u = i + vj
∂f/∂v = ui + uk

Taking the cross product, we get:

(∂f/∂u) x (∂f/∂v) = -vj + uuk - vk

Taking the magnitude, we get:

||(∂f/∂u) x (∂f/∂v)|| = √(1 + u² + v²)

So, the surface area is:

A = ∫∫ √(1 + u² + v²) dudv

To evaluate this integral, we can use a change of variables:

x = u
y = v
z = √(1 + u² + v²)

which gives us a surface that is a hemisphere of radius 1. The surface area of a hemisphere is given by:

A = 2πr²

So, in this case, the surface area is:

A = 2π(1)² = 2π

Therefore, the surface area of the parametric surface given by  with  is 2π.

Step-by-step explanation:

I just took the test:)

The equivalent degree measure or radian measure is,

⇒ r radians = 19π/9

We have to give that,

The proportion is,

⇒ d / 180° = r radians /π radians

Here, Substitute d = 380° in above formula,

⇒ 380° / 180° = r radians /π radians

⇒ 19/9 = r radians /π radians

⇒ 19π/9 = r radians

⇒ r radians = 19π/9

Therefore, The equivalent degree measure or radian measure is,

⇒ r radians = 19π/9

By solving a system of equations we will see that she sold 80 phones and 240 accessories.

Let's define the variables:

x = number of phones.

y = number of accessories.

We know that she makes $160 on commissions, and that she sold 3 times as many accessories as phones, so we can write the system of equations:

y = 3x

x*$8 + y*$4 = $160

To solve the system, we can replace the first equation into the second one.

x*$8 + (3x)*$4 = $160

x*$8 + x*$12 = $160

x*$20 =  $160

x  = $160/$20 = 80

The parameter refers to numbers that summarize the data of the entire population while; Statistics refers to the numbers that summarize the data for a subset of the population or of a sample

No, he expects 99.7% to function within three standard deviations of the mean

The distribution of the sample average will be the student t distribution curve with spread = σ/√n

The mean includes a collection of variables from the sample, hence it is less variable than single observations from the population

As per the Central Limit Theorem, the distribution of the mean call length x from large samples of calls becomes more and more approximately normal as the size of the sample approaches that of the population.

The electrical potential at the point (0,2.2)m is -8.617 V

a) The electrical potential at the origin:

We know that the electric potential at any point P due to a point charge q at a distance r from it is given as:

V = kq/r

where k is a constant and its value is 9 × 10^9 Nm^2/C^2.q = 6 μC = 6 × 10^-6 C  

Distance between the charge and the origin, r1 = sqrt((-4.1)^2 + 0^2) = 4.1 m.

Distance between the charge and the point (0,2.2)m, r2 = sqrt((-4.1)^2 + (2.2)^2) = 4.6 m.

The electrical potential at the origin isV1 = kq/r1= 9 × 10^9 × 6 × 10^-6 / 4.1= 13.846 V

Thus, the electrical potential at the origin is 13.846 V.

b) The electrical potential at the point (0,2.2)m:

Let's find the potential at the point (0,2.2)m.

So the distance between q1 and the point (0,2.2)m is, r11 = sqrt((-4.1)^2 + (2.2)^2) = 4.6 m

Now, the distance between q2 and the point (0,2.2)m is,r22 = sqrt((-6)^2 + (2.2)^2) = 6.2804 m

So, the electrical potential at the point (0,2.2)m is given by,

V2 = kq1/r11 + kq2/r22

    = 9 × 10^9 × 6 × 10^-6 / 4.6 + 9 × 10^9 × -7 × 10^-6 / 6.2804= -8.617 V

Thus, the electrical potential at the point (0,2.2)m is -8.617 V.

The equation for the hyperbola with foci (0,±5) and asymptotes y=± 3/4 x is:

y^2 / 25 - x^2 / a^2 = 1

where a is the distance from the center to a vertex and is related to the slope of the asymptotes by a = 5 / (3/4) = 20/3.

Thus, the equation for the hyperbola is:

y^2 / 25 - x^2 / (400/9) = 1

or

9y^2 - 400x^2 = 900

The center of the hyperbola is at the origin, since the foci have y-coordinates of ±5 and the asymptotes have y-intercepts of 0.

To graph the hyperbola, we can plot the foci at (0,±5) and draw the asymptotes y=± 3/4 x. Then, we can sketch the branches of the hyperbola by drawing a rectangle with sides of length 2a and centered at the origin. The vertices of the hyperbola will lie on the corners of this rectangle. Finally, we can sketch the hyperbola by drawing the two branches that pass through the vertices and are tangent to the asymptotes.

Step-by-step explanation:

10.25x is how much shirts you can buy

17y is how much pants you can buy

50 is the total money you can spend

HOPE THIS HELPED!

The inequality that represents the situation is 10.25x + 17y ≤ 50.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

You go to a store to buy clothes.

The shirt cost 10.25$ each and the pants cost $17 each.

Let x equal the number of shirts and y equal the number of pants you buy. you can only spend up to $50 at the store.

That means,

10.25x + 17y ≤ 50

Therefore, the inequality is 10.25x + 17y ≤ 50.

Applying the exterior angle of a triangle theorem, m∠G = 40°.

According to the exterior angle theorem of a triangle, we have the following equation that is derived:

11x - 4 + 55 = 23x + 3

11x + 51 = 23x + 3

11x - 23x = -51 + 3

-12x = -48

-12x/-12 = -48/-12

x = 4

m∠G = 11x - 4 = 11(4) - 4
