Suppose a city has 810 high-rise buildings, and 29 of these buildings have rooftop gardens. Find the percentage of high-rise buildings with rooftop gardens in this city. Round your answer to the nearest tenth of a percent.

Answers

For this case we can make the following rule of three:
 810 ---------> 100%
 29 -----------> x
 From here, we clear the value of x.
 We have then:
 x = (29/810) * (100)
 x = 3.580246914%
 Round to the nearest tenth of a percent:
 x = 3.6%
 Answer:
 The percentage of high-rise buildings with rooftop gardens in this city is:
 x = 3.6%

To find the percentage of high-rise buildings with rooftop gardens, divide the number of buildings with gardens (29) by the total number of buildings (810), and then multiply by 100. Round the final result to the nearest tenth, which is approximately 3.6%.

To calculate the percentage of high-rise buildings with rooftop gardens, we use the formula:

Percentage = (Part / Whole)  imes 100

Where the Part is the number of buildings with rooftop gardens, and the Whole is the total number of high-rise buildings.

Substituting the given values:

Percentage = (29 / 810) times 100

Carrying out the division first gives us:

Percentage ≈ 0.035802469 times 100

Finally, multiplying by 100 to find the percentage, we get:

Percentage ≈ 3.58

After rounding to the nearest tenth of a percent, we obtain:

Percentage ≈ 3.6%

3.6% of the high-rise buildings in the city have rooftop gardens.

sq root of x +11 =15

Answers

Hello!

You can solve for x by subtracting 11 from 15 to get 4. Once you've got 4, you can power 4 by 2 (4²) to get 16 as your answer

x=16

So the value of x is 16
 
I hope this helps!
Remark
I take it you want to find x.

Square both sides.
(sqrt(x + 11))^2 = (15)^2
 x + 11 = 225  Subtract 11 from both sides.
x = 225 - 11
x = 214

Edit
This answer is edited to reflect which interpretation is correct. If you give out Brainlys (and you should) give it to Brick123. We all need them.

Sqrt(x) + 11 = 15   Subtract 11 from both sides.
sqrt(x) = 15 - 11
sqrt(x) = 4             Square both sides.
(sqrt(x)^2 = 4^2
x = 16


 

the angle of elevation of an object from a point 200 meters above a lake is 30 degrees and the angle of depression of it's image in the lake is 45 degrees. Find the height of the object above the lake.

Answers

Let h and d represent the height of the object above the lake and its horizontal distance from the observer, respectively.

Looking at the reflection of the object in the lake's surface is equivalent to observing the object at distance h below the lake's surface, or observing it from 200 m below the lake's surface. Considering the latter case, we have
  (h+200)/d = tan(45°)
  (h -200)/d = tan(30°)
Solving these for d and equating the results gives
  (h+200)/tan(45°) = (h -200)/tan(30°)
Solving for h, we get
  h(1/tan(30°) -1/tan(45°)) = 200(1/tan(45°) +1/tan(30°))
  h = 200(tan(45°) +tan(30°))/(tan(45°) -tan(30°))
  h ≈ 746.41

The object is about 746.4 meters above the lake.

a proton moves in an electric field such that its acceleration a is a=-20(1+2t)^-2, where t is the time in seconds. Find the velocity as a function of time if v sub zero =30 when t=0

Answers

a = dv/dt, therefore, to get an expression for v(t), we would integrate the expression for a:
a = -20/(1+2t)^2
v = (1/2)*20/(1+2t) + k = 10/(1+2t) + k
At t = 0:
v0 = 10/1 + k = 30
Therefore, k = 20, and the expression for v(t) is
v(t) = 10/(1+2t) + 20

Then find the area bounded by the two graphs of y=2x^2−24x+42 and y=7x−2x^2

Answers

To find the area under a curve, we integrate the function. To find the area bound between two curves, we integrate the difference of the functions. That is, we find:

[tex] \int\limits^a_b {(f(x)-g(x))} \, dx [/tex]

If you think about it, we are really doing this with all integration, only the second function is just y=0.

First, we need to figure out which function is on top. In this case we know that [tex]2x^2-24x+42[/tex] is a positive parabola while [tex]7x-2x^2[/tex] is negative, so the negative parabola will be on top. It is always a good idea to draw a rough sketch of the graphs because the curves could intercept multiple times, flipping which graph is on top at different intervals.

Next, we need to determine the bounds. These will be where the two graphs intercept, so we can just set them equal to each other and solve for x:

[tex]2x^2-24x+42=7x-2x^2[/tex]

Combine like terms:

[tex]4x^2-31x+42[/tex]

Now factor and find the zeros. We can use the quadratic formula:

[tex] \frac{31+ \sqrt{31^2-4(4)(42)} }{8} [/tex]

and

[tex] \frac{31- \sqrt{31^2-4(4)(42)} }{8} [/tex]

x = 1.75 and 6

[tex] \int\limits^6_{1.75} {((7x-2x^2)-(2x^2-24x+42))} \, dx [/tex]

[tex] \int\limits^6_{1.75} {(-4x^2+31x-42)} \, dx [/tex]

Solve:

[tex] \frac{-4x^3}{3} + \frac{31x^2}{2} - 42x [/tex]

Plug in bounds:

[tex]\frac{-4(6)^3}{3} + \frac{31(6)^2}{2} - 42(6)-(\frac{-4(1.75)^3}{3} + \frac{31(1.75)^2}{2} - 42(1.75))[/tex] = 51.17708





A half cylinder lies on its side. What is the exact volume of the half cylinder?

150 π in3
300 π in3
450 π in3
600 π in3

Answers


pi*r²*h
pi*r²*h/2
r=10/2-----> r=5 in
h=12 in
=pi*5²*12/2----> 150*pi in³

so finally the correct answer would be the first option 
150*pi in3

The required exact volume of the half cylinder is 150 π in³. Option A is correct.

To calculate the volume of a half cylinder, we need to find the volume of a full cylinder and then divide it by 2.

The formula for the volume of a cylinder is given by:

Volume = π * r² * h

where π is a constant approximately equal to 3.14159, r is the radius of the cylinder, and h is the height or length of the cylinder.

Given that the diameter of the cylinder is 10 inches, we can find the radius by dividing the diameter by 2:

Radius (r) = 10 in / 2 = 5 in

The height or length of the cylinder is given as 12 inches.

Now we can calculate the volume of the full cylinder:

Volume = π * (5 in)² * 12 in = 300 π in^3

Finally, to find the volume of the half cylinder, we divide the volume of the full cylinder by 2:

Volume of Half Cylinder = (300 π in³) / 2 = 150 π in³

Therefore, the exact volume of the half cylinder is 150 π in³.

[tex] \tan( \sqrt{x } ) [/tex]

Answers

[tex]\displaystyle\lim_{h\to0}\frac{\tan\sqrt{x+h}-\tan x}h[/tex]

Employ a standard trick used in proving the chain rule:

[tex]\dfrac{\tan\sqrt{x+h}-\tan x}{\sqrt{x+h}-\sqrt x}\cdot\dfrac{\sqrt{x+h}-\sqrt x}h[/tex]

The limit of a product is the product of limits, i.e. we can write

[tex]\displaystyle\left(\lim_{h\to0}\frac{\tan\sqrt{x+h}-\tan x}{\sqrt{x+h}-\sqrt x}\right)\cdot\left(\lim_{h\to0}\frac{\sqrt{x+h}-\sqrt x}h\right)[/tex]

The rightmost limit is an exercise in differentiating [tex]\sqrt x[/tex] using the definition, which you probably already know is [tex]\dfrac1{2\sqrt x}[/tex].

For the leftmost limit, we make a substitution [tex]y=\sqrt x[/tex]. Now, if we make a slight change to [tex]x[/tex] by adding a small number [tex]h[/tex], this propagates a similar small change in [tex]y[/tex] that we'll call [tex]h'[/tex], so that we can set [tex]y+h'=\sqrt{x+h}[/tex]. Then as [tex]h\to0[/tex], we see that it's also the case that [tex]h'\to0[/tex] (since we fix [tex]y=\sqrt x[/tex]). So we can write the remaining limit as

[tex]\displaystyle\lim_{h\to0}\frac{\tan\sqrt{x+h}-\tan\sqrt x}{\sqrt{x+h}-\sqrt x}=\lim_{h'\to0}\frac{\tan(y+h')-\tan y}{y+h'-y}=\lim_{h'\to0}\frac{\tan(y+h')-\tan y}{h'}[/tex]

which in turn is the derivative of [tex]\tan y[/tex], another limit you probably already know how to compute. We'd end up with [tex]\sec^2y[/tex], or [tex]\sec^2\sqrt x[/tex].

So we find that

[tex]\dfrac{\mathrm d\tan\sqrt x}{\mathrm dx}=\dfrac{\sec^2\sqrt x}{2\sqrt x}[/tex]

Find the derivative of f(x) = (1 + 5x2)(x − x2) in two ways. use the product rule. f '(x) = perform the multiplication first. f '(x) = do your answers agree? yes no

Answers

Answer:

The answers agree.

[tex]f^{\prime}(x) = - 20x^{3} + 15x^{2} - 2x + 1[/tex]

Step-by-step explanation:

The product rule is:

[tex]f(x) = g(x)h(x)[/tex]

[tex]f^{\prime}(x) = g^{\prime}(x)h(x) + g(x)h^{\prime}(x)[/tex]

In this problem, we have that:

[tex]f(x) = (1 + 5x^{2})(x - x^{2})[/tex]

So

[tex]g(x) = 1 + 5x^{2}[/tex]

[tex]g^{\prime}(x) = 10x[/tex]

[tex]h(x) = x - x^{2}[/tex]

[tex]h^{\prime}(x) = 1 - 2x[/tex].

[tex]f^{\prime}(x) = g^{\prime}(x)h(x) + g(x)h^{\prime}(x)[/tex]

[tex]f^{\prime}(x) = (10x)*(x - x^{2}) + (1 + 5x^{2})(1-2x)[/tex]

[tex]f^{\prime}(x) = 10x^{2} - 10x^{3} + 1 - 2x + 5x^{2} - 10x^{3}[/tex]

[tex]f^{\prime}(x) = - 20x^{3} + 15x^{2} - 2x + 1[/tex]

Multiplication first:

[tex]f(x) = (1 + 5x^{2})(x - x^{2})[/tex]

[tex]f(x) = x - x^{2} + 5x^{3} - 5x^{4}[/tex]

[tex]f(x) = -5x^{4} + 5x^{3} - x^{2} + x[/tex]

[tex]f^{\prime}(x) = -20x^{3} + 15x^{2} - 2x + 1[/tex]

Comparing the results, we can see that the derivatives obtained using the two methods are indeed the same. The answer is yes.

What's the function about?

The derivative of f(x) = (1 + 5x2)(x − x2) can be found using the product rule and by performing the multiplication first.

Using the product rule:

The product rule states that the derivative of f(x)g(x) is f′(x)g(x)+f(x)g′(x).

In this case, f(x) = 1 + 5x2 and g(x) = x − x2. So the derivative of f(x)g(x) is:

f′(x)g(x)+f(x)g′(x)

=(10x+10x3)(x−x2)+(1+5x2)(2x−2x3)

=10x2−10x3+10x3−10x4+2x−2x3+1+10x2−10x3

=−10x4+12x2+2x

Performing the multiplication first:

We can first multiply out the expression (1 + 5x2)(x − x2) to get:

x2−5x4+x3−5x3+x−x2

=−5x4+12x2+x

Then, we can take the derivative of this expression to get the same derivative as we found using the product rule:

f′(x)=−10x4+12x2+2x

Therefore, the derivative of f(x) = (1 + 5x2)(x − x2) is -10x4+12x2+2x, regardless of whether we use the product rule or perform the multiplication first.

Find the area of the figure

Answers

You can solve each figure individually; the parallelogram, and the trapezoid.

The parallelogram, you can just do base * height. The base is 11 yards, and the height is 4 yards. 11 * 4 = 44 square yards.

Now for the trapezoid. If you split it up into a rectangle and a triangle, it becomes much more easier to solve. The rectangle and triangles can be made by splitting the figure down the center. This makes a rectangle with a length of 7 yards and a height of 8, and a triangle with a base of 7 yards and a height of 8 as well.

Solve for the area of both shapes.

The rectangle: Multiply length * height: 7 * 8 = 56 square yards

The triangle: Multiply base * height, and then divide by 2: 7 * 8 = 56
56 / 2 = 28 square yards

Now add the areas together.

28 + 56 + 44 = 128 square yards

Hope this helped!
These are the steps:
1. Find area of the trapezium.
2. Find area of the parallelogram.
3. Add the 2 areas together.


Step 1: Find the area of the trapezium:

Answers

The answer is D 

The graph reflects that she is getting paid 10 dollars an hour

If you plot the points, you will see she makes 5 dollars every half hour

Answer:

Option D is the answer.

Step-by-step explanation:

This graph represents a linear function representing earnings of Marie at y axis and hours of working at x axis. To get the change in Marie's earnings for every 5 hours we will find the slope of the given line.

Slope of the line will define the rate of change in earning of Marie with respect to the time.

End points of the line at time t = 0 and t = 5 hours are (0, 0) and (5, 50).

Therefore slope = [tex]\frac{y-y'}{x-x'}=\frac{50-0}{5-0}=\frac{50}{5}=10[/tex]

So for each hour she works her earnings go up by $10.

Option D is the correct option.

A rectangular storage area is to be constructed along the side of a tall building. a security fence is required along the remaining 3 sides of the area. what is the maximum area that can be enclosed with 800 m of fencing? (a = lw)

Answers

Let l represent the length of fence parallel to the side of the building. Then the width will be that of half the remaining fence, (800 -l)/2. The total area will be
  A = lw = l(800 -l)/2

This is the equation of a downward-opening parabola with zeros at l=0 and l=800. The zeros are symmetrical about the axis of symmetry of the parabola, which axis goes through the vertex. That is, the vertex is located at
  l = (0 +800)/2 = 400

The maximum aea that can be enclosed is 400 m long by 200 m wide, so is
  (400 m)×(200 m) = 80,000 m²
Final answer:

To find the maximum area enclosed with 800 m of fencing, the dimensions of the rectangular storage area need to be determined. The perimeter equation is derived to eliminate a variable, allowing the area to be expressed in terms of the remaining variable. Using this approach, the dimensions that maximize the area can be found.

Explanation:

To find the maximum area that can be enclosed with 800 m of fencing, we need to determine the dimensions that will result in the largest possible area. Let's assume the length of the rectangular storage area is L and the width is W.

Since there are 3 sides already covered by the security fence, the perimeter of the rectangular storage area will be: 2L + W = 800 m.

To find the maximum area, we need to eliminate one variable from the equation above. We can do this by expressing W in terms of L and substituting it back into the area formula A = LW.

By applying this approach, we can find the dimensions of the rectangular storage area that will enclose the maximum area with 800 m of fencing.

Then use the 45-gallon jug to scoop out the water 11 times.
Amount of water scooped out = 11 x 45 = 455 gallons

Water remaining = 496 - 450 = 1 gallon.

4*124 = 496
11*45 = 495

Fill the 124-gallon jug 4 times, emptying it each time into the 45-gallon jug. After the 45-gallon jug has been filled 11 times, there will be 1 gallon remaining in the 124-gallon jug.

_____
Mathematically, this works fine. In practice, you're looking for a 1-gallon difference after handling 495 gallons of water. That's about 0.2% of the total amount of water transferred. Any error along the way will substantially affect the outcome.

hey can you please help me posted picture of question

Answers

The solutions to the given quadratic equation can be determined using quadratic formula.

[tex]x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a} [/tex]

b =coefficient of x term = -2
a = coefficient of squared term = 1
c = constant term = 10

Using the values in the above formula we get:

[tex]x= \frac{2+- \sqrt{4-4(1)(10)} }{2(1)} \\ \\ x= \frac{2+- \sqrt{-36} }{2} \\ \\ x= \frac{2+-6i}{2} \\ \\ x=1+3i, x=1-3i [/tex]

So the correct answer to this question is option A

How many lines of symmetry does a regular polygon with 32 sides have

Answers

32. 16 through opposite vertices and 16 through the centres of opposite sides 

A regular polygon with 32 sides has 16 lines of symmetry.

What is Polygon?

A polygon is a plane figure made up of line segments connected to form a closed polygonal chain.

We need to find the number of  lines of symmetry does a regular polygon with 32 sides have.

The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called the line of symmetry

A regular polygon with 32 sides has 16 lines of symmetry.

This is because each side is equal in length and angles, creating a mirrored effect when each side is divided in half.

Hence, a regular polygon with 32 sides has 16 lines of symmetry.
