Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 14 feet and a height of 11 feet. Container B has a diameter of 10 feet and a height of 19 feet. Container A is full of water and the water is pumped into Container B until Container B is completely full.

Answers

Answer 1

After filling Container B completely, there are approximately 209.56 cubic feet of water left in Container A.

How to solve

Container A:

Diameter = 14 feet

Radius = Diameter / 2 = 14 / 2 = 7 feet

Height = 11 feet

Volume of Container A = π * (7^2) * 11 ≈ 1,696.46 cubic feet

Container B:

Diameter = 10 feet

Radius = Diameter / 2 = 10 / 2 = 5 feet

Height = 19 feet

The volume of Container B = [tex]π * (5^2) * 19[/tex] ≈ 1,486.90 cubic feet

Now, let's find out how much water is left in Container A after filling Container B completely.

Water left in Container A = Volume of Container A - Volume of Container B

Water left in Container A ≈ 1,696.46 - 1,486.90 ≈ 209.56 cubic feet

So, after filling Container B completely, there are approximately 209.56 cubic feet of water left in Container A.

(42) Using a waste factor of 6 percent, determine the number of cubic yards of concrete needed to pour the foundation walls shown in Figure 11.4. The footing is 12 foot wide and 1 foot thick.

Answers

The 7.34 cubic yards of concrete needed to pour the foundation walls, which is calculate the volume of the walls and then add the waste factor of 6%.

To find the volume of the concrete needed to pour the foundation walls, we first need to find the total area of the walls. We can do this by breaking it down into three sections

The two 26 ft x 1 ft walls

Area = 2 x (26 ft x 1 ft) = 52 sq ft

The two 42 ft x 1 ft walls

Area = 2 x (42 ft x 1 ft) = 84 sq ft

The 12 in x 15 in x 12 ft wall

First, we need to convert the dimensions to feet:

Length = 12 in ÷ 12 = 1 ft

Breadth = 15 in ÷ 12 = 1.25 ft

Height = 12 ft

Area = (1 ft + 1.25 ft) x 2 x 12 ft = 51 ft²

Total area of the walls = 52 sq ft + 84 sq ft + 51 sq ft = 187 sq ft

Now, we need to add the waste factor of 6% to this to account for any material that may be lost or wasted during the pouring process

Total area with waste factor = 187 sq ft + 6% of 187 sq ft = 198.22 sq ft

Finally, we need to calculate the volume of concrete needed, assuming a thickness of 1 ft

Volume = area x thickness = 198.22 sq ft x 1 ft = 198.22 cubic ft

Since 1 cubic yard is equal to 27 cubic feet, we can convert the volume to cubic yards

Volume in cubic yards = 198.22 cubic ft ÷ 27 = 7.34 cubic yards

Therefore, we need 7.34 cubic yards of concrete to pour the foundation walls with a 6% waste factor.

Trigonometry Question

Answers

Answer:  To show that the equation "3sin () tan () = 5cos () - 2" is equivalent to the equation "(4 cos() - 3)(2 cos () + 1) = 0", we need to simplify the first equation and check if it has the same solutions as the second equation.

Starting with the first equation:

3sin () tan () = 5cos () - 2

Using the identity tan () = sin () / cos (), we can write:

3sin () (sin () / cos ()) = 5cos () - 2

Multiplying both sides by cos (), we get:

3sin^2 () = (5cos () - 2)cos ()

Using the identity sin^2 () + cos^2 () = 1 and rearranging, we get:

3(1 - cos^2 ()) = 5cos^2 () - 2cos ()

Expanding and rearranging, we get:

5cos^2 () - 2cos () - 3 + 3cos^2 () = 0

Simplifying, we get:

8cos^2 () - 2cos () - 3 = 0

Now, we can use the quadratic formula to solve for cos ():

cos () = [2 ± sqrt(2^2 - 4(8)(-3))]/(2(8))

cos () = [2 ± sqrt(100)]/16

cos () = (1/4) or (-3/8)

Substituting these values back into the original equation, we can verify that they satisfy the equation.

Now, let's consider the second equation:

(4 cos() - 3)(2 cos () + 1) = 0

This equation is satisfied when either 4cos() - 3 = 0 or 2cos() + 1 = 0.

Solving for cos() in the first equation, we get:

4cos() - 3 = 0

cos() = 3/4

Substituting this value back into the original equation, we can verify that it satisfies the equation.

Solving for cos() in the second equation, we get:

2cos() + 1 = 0

cos() = -1/2

Substituting this value back into the original equation, we can also verify that it satisfies the equation.

Therefore, we have shown that the equation "3sin () tan () = 5cos () - 2" is equivalent to the equation "(4 cos() - 3)(2 cos () + 1) = 0".

To find the height of a pole, Elka lays a mirror on the level ground 20 feet from the base of the pole. She moves back away from the mirror until she can exactly see the top of the pole. If she backed way 5.5 feet and her eyes are 5 feet above the ground, how tall is the flag pole?

Answers

The height of the pole is 18.18 feet

Given data ,

Elka uses similar triangles to find the height of the pole. The situation forms two similar right triangles: one with the pole and the mirror, and another with Elka's eyes and the mirror.

Let's denote the height of the pole as "h" feet.

Distance from the base of the pole to the mirror = 20 feet

Distance Elka moves back away from the mirror = 5.5 feet

Height of Elka's eyes above the ground = 5 feet

Using the concept of similar triangles, we can set up the following proportion:

h / 20 = 5 / 5.5

Multiply by 20 on both sides , we get

h = 100 / 5.5

h = 18.18 feet

Now ,

Let the point be P ( 1 , -12 )

And , to determine if the point (1, -12) is on the graph of the function f(x) = 3x² - 6x - 9, we can substitute x = 1 and y = -12 into the equation and check if it satisfies the equation.

suppose mapping f : Z->Z is defined as f(x)=x^2 (Z denotes the set of integers). Show that f is a function

Answers

To show that f(x) = x^2 is a function, we need to show that for every element in the domain of f(x), there exists a unique element in the range of f(x). In this case, the domain of f(x) is Z (the set of integers) and the range of f(x) is also Z.

For any integer x, x^2 is also an integer. Therefore, for every element in the domain of f(x), there exists an element in the range of f(x).

Now we need to show that this element in the range is unique. Suppose there exist two elements a and b in Z such that a^2 = b^2. Then we have:

a^2 - b^2 = 0

(a - b)(a + b) = 0

Since a and b are integers, either a - b = 0 or a + b = 0. If a - b = 0, then a = b and hence the element in the range is unique. If a + b = 0, then a = -b and hence again the element in the range is unique.

Therefore, we have shown that for every element in the domain of f(x), there exists a unique element in the range of f(x), which means that f(x) = x^2 is indeed a function.

Answers

The equivalent speed in still water to achieve the actual speed is 27.172 km/h

Given data ,

The boat's velocity vector in still water will have two components: one along the north direction (opposite to the current) with magnitude "v" km/h, and one along the northwest direction (due to the current) with magnitude 4 km/h.

Since the boat is moving in a direction that is 45 degrees between north and northwest, we can use trigonometry to find the component of velocity in the northwest direction. By using the cosine of 45 degrees, we get:

Component of velocity in northwest direction = 4 km/h x cos(45 degrees) = 4 km/h x 0.707 = 2.828 km/h

Now , adding the components of velocity in the north and northwest directions should result in a speed of 30 km/h, which is the real speed needed to go through still water.

v + 2.828 = 30

Step-by-step explanation:

We can work percentage problems using the formula

P%x = y, where P is the percentage, x is the "of" value in the problem, and y is the "is" value in the problem.

First, we must convert the percentage to decimal form for an easier problem  We can either dividing the percentage by 100 since a percentage is always out of 100 (e.g., 30 / 100 = 0.30) Or we can imagine the percentage sign as a decimal and move it over two places to the right (30% = 30.00 = 0.30)

Thus, in the formula, our p value is 0.30, our x ("of") value is 26.5 and we're trying to find our y ("is") value:

0.30 * 26.5 = y

7.95 = y

Juan deposited $7000 into an account with a 3.4% annual interest rate, compounded quarterly. Assuming that no withdrawals are made, how long will it take for the investment to grow to $9737?
Do not round any intermediate computations, and round your answer to the nearest hundredth.

Answers

Answer:

It will take approximately 6.89 years for the investment to grow to $9737.

Step-by-step explanation:

We can use the formula for compound interest to solve this problem:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment

P = the present value of the investment

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

We know that P = $7000, r = 0.034, n = 4 (since the interest is compounded quarterly), and we want to find t when A = $9737.

$9737 = $7000(1 + 0.034/4)^(4t)

Divide both sides by $7000:

1.391 = (1 + 0.034/4)^(4t)

Take the natural logarithm of both sides:

ln(1.391) = ln[(1 + 0.034/4)^(4t)]

Use the power rule of logarithms:

ln(1.391) = 4t * ln(1 + 0.034/4)

Divide both sides by 4 ln(1 + 0.034/4):

t = ln(1.391) / [4 * ln(1 + 0.034/4)]

Using a calculator, we find:

t ≈ 6.89 years

Therefore, it will take approximately 6.89 years for the investment to grow to $9737.

Evaluating the integral using spherical coordinates

Given that

[tex]\int\limits^a_{-a} \int\limits^{\sqrt{a^2 - y^2}}_{-\sqrt{a^2 - y^2}} \int\limits^{\sqrt{a^2 -x^2 - y^2}}_{-\sqrt{a^2 - x^2 - y^2}} (x^2z + y^2z + z^3) dz dx dy[/tex]

To change to spherical coordinates, we need to express x, y, and z in terms of spherical coordinates: r, θ, and Φ .

In particular, we have

[tex]x &= r \sin\phi \cos\theta, \\y &= r \sin\phi \sin\theta, \\z &= r \cos\phi[/tex]

The Jacobian for the transformation is r² sin(Φ), and the limits of integration become

[tex]-a &\leq x \leq a \quad \Rightarrow \quad 0 \leq r \leq a, \\-\sqrt{a^2 - y^2} &\leq y \leq \sqrt{a^2 - y^2} \quad \Rightarrow \quad 0 \leq \phi \leq \frac{\pi}{2}, \\-\sqrt{a^2 - x^2 - y^2} &\leq z \leq \sqrt{a^2 - x^2 - y^2} \quad \Rightarrow \quad 0 \leq \theta \leq 2\pi.[/tex]

Substituting into the integral, we have

[tex]&\int_{0}^{a} \int_{0}^{\frac{\pi}{2}} \int_{0}^{2\pi} (r^2\sin^2\phi\cos\theta\cdot r\cos\phi + r^2\sin^2\phi\sin\theta\cdot r\cos\phi + r^3\cos^3\phi) r^2 \sin\phi,d\theta d\phi dr \[/tex]

[tex]&\quad = \int_{0}^{a} \int_{0}^{\frac{\pi}{2}} \int_{0}^{2\pi} r^3\sin\phi\cos\phi (\sin^2\phi\cos\theta + \sin^2\phi\sin\theta + \cos^2\phi) , d\theta d\phi dr \[/tex]

find the work done of a moving particle in the surface center c(0,0,3) of radiu r=5, on the plane z=3 if the force field F = (2x +y_2Z)i + (2x_4y+Z)j (x-2y-Z²) k​

Answers

Answer:

75 - 25π.

Step-by-step explanation:

To find the work done by a force field on a particle moving along a curve, we use the line integral of the force field over that curve.

In this case, the curve is a circle of radius 5 centered at (0, 0, 3) lying on the plane z = 3. We can parameterize this curve using polar coordinates as:

r(t) = (5cos(t), 5sin(t), 3), where t goes from 0 to 2π.

The differential of the curve, dr(t), is given by:

dr(t) = (-5sin(t), 5cos(t), 0) dt

Now we need to calculate the work done by the force field F along this curve. The line integral of F over the curve is given by:

W = ∫ F · dr = ∫ (2x +y²Z)dx + (2x-4y+Z)dy + (x-2y-Z²)dz

Substituting x = 5cos(t), y = 5sin(t), and z = 3, we get:

W = ∫ (10cos(t) + 25sin²(t)·3) (-5sin(t))dt

∫ (10cos(t) - 20sin(t) + 3) (5cos(t))dt

∫ (5cos(t) - 10sin(t) - 9) (0)dt

Simplifying, we get:

W = -75∫sin(t)cos(t)dt + 50∫cos²(t)dt + 0

Using the trigonometric identities sin(2t) = 2sin(t)cos(t) and cos²(t) = (1 + cos(2t))/2, we can simplify this further:

W = -75∫(1/2)sin(2t)dt + 25∫(1 + cos(2t))dt

= -75·(1/2)·(-cos(2t))∣₀^(2π) + 25·(t + (1/2)sin(2t))∣₀^(2π)

= 75 - 25π

Therefore, the work done by the force field F on the particle moving along the circle of radius 5 centered at (0, 0, 3) lying on the plane z = 3 is 75 - 25π.

A rectangle's length is twice as long as it is wide. If the length is doubled and its breadth
is halved, the new rectangle will have a perimeter of 12 m longer than the original
rectangle's perimeter.
What are the dimensions of these rectangles?

Answers

Let's assume that the width of the original rectangle is "w". Therefore, the length of the original rectangle is "2w".

The perimeter of the original rectangle is given by:
P1 = 2(l + w) = 2(2w + w) = 6w

If the length is doubled and the width is halved, the new length becomes "4w" and the new width becomes "0.5w". Therefore, the new perimeter is given by:
P2 = 2(l + w) = 2(4w + 0.5w) = 9w

We know that the new perimeter is 12 meters longer than the original perimeter. Therefore:
P2 - P1 = 9w - 6w = 12
3w = 12
w = 4

Therefore, the width of the original rectangle is 4 meters and the length of the original rectangle is 2w = 8 meters.

The width of the new rectangle is 0.5w = 2 meters and the length of the new rectangle is 4w = 16 meters.
