You are riding in a hot air balloon on Valentine’s Day withyour sweetheart. As you get ready to set your balloon downyou notice

that while your balloon is 500 ft above ground, your friends balloon is 800 ft above ground. The plan is for both balloons to descend straight down. Your balloon willland right at the edge of the lake below, but it appears thatyour friends will be pretty far away. You can see a reflectionof their balloon right in the middle (direct center) of the 1200 ft wide lake below.How far away from the lake will your friends touch down?

Answer:

Try 750 ft?

Step-by-step explanation:

Proportion:

800/500 = 1,200/x

Solve:

1,200 / 800 = 1.5

1.5 * 500 = 750

Hope this helped!

Find the dimensions of the closed rectangular box with maximum volume that can be inscribed in the unit sphere.
Anestetic [448]

Answer:

Step-by-step explanation:

Let the rectangle have (x,y,z) as vertex in positive octant.  The rectangular box has to be necessarily symmetrical about all the three axes.

Then the sides of the box would be

2x,2y,2z

Volume = 8xyz

Maximize volume subject to

x^2+y^2+z^2 =1

i.e. g(x,y,z) = x^2+y^2+z^2 -1=0

Use Lagrangian multipliers , we have

∇f(x,y,z)=λ∇g(x,y,z)at the maximum

∇f(x,y,z)=λ∇g(x,y,z) =(8yz,8xz,8xy)\\∇g(x,y,z)=(2x,2y,2z)

8yz=2λx8xz=2λy8xy=2λz

Dividing we get

\frac{y}{x} =\frac{x}{y} \\x^2=y^2

Similarly y^2=z^2

Thus we get 3x^2 =1\\x = \frac{1}{\sqrt{3} }

Hence dimensions are

(2x,2y,2z)

So dimensions are

\frac{2}{\sqrt{3} } ,\frac{2}{\sqrt{3} } ,\frac{2}{\sqrt{3} } )

Distance formula for (3,-2) and (5,-3)
Soloha48 [4]

Answer:

d = 2.2

Step-by-step explanation:

Using the distance formula, you would plug in the numbers into the equation. d = √(5 - 3)^2 + ( -3 + 2)^2. So (5 - 3) is 2, and (-3 + 2) is -1. Then square both of the answers, and the equation becomes, d = √4 + 1. And that equals 5, so then you would find the square root, which would be approximately 2.2

What is the surface area of the triangular prism?
ryzh [129]

Answer:

135 square feet.

Step-by-step explanation:

A triangular prism. The rectangular sides are 8 feet by 2.5 feet, 8 feet by 6 feet, and 8 feet by 6.5 feet. The triangular sides have a base of 2.5 feet and a height of 6 feet.

The prism has two triangular faces and three rectangular faces.

So, the surface area of the prism will be

2(\frac{1}{2} \times 2.5 \times 6) + (8 \times 2.5) + (8 \times 6) + (8 \times 6.5)

= 15 + 20 + 48 + 52

= 135 square feet. (Answer)

Five spheres are being painted for a display at a store. If the diameter of each sphere is
ivanzaharov [21]
<h2>Hello!</h2>

The answer is:

The total area is:

TotalArea=192.4cm^{2}

<h2>Why?</h2>

To find the cloasest value to the total surface area that will be painted, we need to calculate the area of a single sphere, and then, multiply it by 5.

We know that the diameter of each sphere is 7 centimeters, so, calculating we have:

Calculating the radius we have,

diameter=2*radius\\\\radius=\frac{diameter}{2}=\frac{7cm}{2}=3.5cm

Then, calculating the area, we have:

Area=\pi radius^{2}

Area=\pi 3.5cm^{2}=38.49cm^{2}

Now that we have calculated the surface area of a single sphere, we need to calculate the area of the five spheres.

So, calculating we have:

TotalArea=5*38.48cm^{2}=192.4cm^{2}

Hence, the total area is:

TotalArea=192.4cm^{2}

Have a nice day!
