a) The range of chest measurements contains 68% which falls closest to the mean is between 38 inches and 42 inches

b) The chest measurements for the 2.5% of the men with the smallest chest measurements in the population to be approximately 36 inches

Given data ,

The Empirical rule, also known as the 68-95-99.7 rule, is a statistical guideline that describes the approximate distribution of data in a normal distribution.

Approximately 68% of the data falls within one standard deviation (σ) of the mean (μ)

Approximately 95% of the data falls within two standard deviations of the mean (μ ± 2σ)

Approximately 99.7% of the data falls within three standard deviations of the mean (μ ± 3σ)

It would be within one standard deviation of the mean for the range of chest measures that accounts for 68% of the data and is closest to the mean. Since the standard deviation is 2 inches and the mean chest measurement is 40 inches, we can get the range as follows:

Mean - 1 standard deviation = 40 - 2 = 38 inches

Mean + 1 standard deviation = 40 + 2 = 42 inches

b)

We may look at the bottom end of the distribution to obtain the chest dimensions for the 2.5% of males with the smallest chest measurements in the population. The empirical rule states that 2.5% or less of the data goes outside of two standard deviations of the mean. So, using the following formula, we can get the chest size of the 2.5% of men:

Mean - 2 standard deviations = 40 - 2(2) = 36 inches

Hence , the standard deviations are solved

Jasica should invest $878.84 per month in a sinking fund with 3% interest compounded monthly to accumulate $83,000 in 7 years.

To determine how much Jasica should make in a sinking fund, we can use the formula for the future value of an annuity due:

FV = PMT x [tex](((1 + r/n)^nt[/tex] - 1) / (r/n))

Where:

FV = future value

PMT = monthly payment

r = interest rate (as a decimal)

n = number of compounding periods per year

t = number of years

In this issue, we are solving for PMT.

Given:

FV = $83,000,

r = 0.03 (3% expressed as a decimal),

n = 12 (monthly compounding),

t = 7 years.

Plugging in the values, we have:

$83,000 = PMT x [tex](((1 + 0.03/12)^(12*7)[/tex] - 1) / (0.03/12))

Simplifying:

$83,000 = PMT x (94.4523)

PMT = $83,000 / 94.4523

PMT = $878.84 (rounded to the nearest cent)

Therefore, Jasica should invest $878.84 per month in a sinking fund with 3% interest compounded monthly.

The value of x is, x = 6 ft

Now, We can formulate;

Area of the polygon = area of the square + 2(area of the triangle)

Here, We have;

Area of the polygon = 176 ft²

So, Area of the square = length × width

                                   = 16 × 8

                                  = 128

And, Area of the two triangles = 2( 1/2 x base x height)

                                               = 2(1/2 × x × 8)

                                               = 8x

Now, Plug in the above values into the equation for area of the polygon.

Thus: We get;

176 = 128 + 8x

Subtract 128 from each side

176 - 128 = 8x

48 = 8x

Divide both sides by 8

6 = x

x = 6 ft

Thus, The value of x is, x = 6 ft

We have shown that the solution to the differential equation dp/dt = -0.1P is P = 495e^(1.1t).

We have,

To show that the solution to the differential equation dp/dt = -0.1P is

P = 495e^(1.1t),

we can use separation of variables and integration.

Starting with the differential equation:

dp/dt = -0.1P

We can separate the variables by dividing both sides by P and multiplying both sides by dt:

dp/P = -0.1 dt

Integrate both sides:

∫ dp/P = -0.1 ∫ dt

Integrating the left-hand sid.

ln|P| = -0.1t + C

where C is the constant of integration.

To solve for C, we can use an initial condition.

Suppose that when t = 0, P = P0.

Then we have:

ln|P0| = -0.1(0) + C

ln|P0| = C

Substituting this value of C back into the equation for P.

ln|P| = -0.1t + ln|P0|

ln|P/P0| = -0.1t

Taking the exponential of both sides.

P/P0 = e^(-0.1t)

Multiplying both sides by P0.

P = P0 e^(-0.1t)

We can substitute P0 = 495 (since P(0) = 495 is given in the solution) and e^(-0.1t) = e^(1.1t)/e^t.

P = 495 e^(1.1t)/e^t

Simplifying the expression by combining the exponentials.

P = 495 e^(0.1t)

which is the same as the given solution.

Therefore,

We have shown that the solution to the differential equation dp/dt = -0.1P is P = 495e^(1.1t).

Answer:

Many buildings and structures around us involve transformed shapes in their design. For example, a skyscraper may have a rectangular base that is transformed into a triangular shape as it reaches higher levels. This transformation is achieved by using a technique called tapering, where the building's width gradually decreases as it goes up, resulting in a triangular shape at the top.

Another common transformation is the use of rotation, which is seen in the design of many cylindrical structures like water towers or chimneys. The cylinder is rotated around its axis to create a three-dimensional shape.

These transformed shapes contribute to the design of the object in many ways. For instance, the triangular shape of a skyscraper's top helps to reduce wind resistance and improve stability. Tapering also allows more sunlight to reach street level and reduces the impact of shadows on the surrounding area. In the case of cylindrical structures, rotation can provide structural stability while minimizing the amount of material used in the construction.

Overall, the use of transformed shapes in building and structure design helps to achieve specific aesthetic and functional goals, from stability to energy efficiency.

Step-by-step explanation:

Answer:

The Empire State Building is a skyscraper in Midtown Manhattan, New York City, on Fifth Avenue between West 33rd and 34th Streets. It has a roof height of 1,250 feet (381 m), and with its antenna spire included, it stands a total of 1,454 feet (443.2 m) high. Its name is derived from the nickname for New York, the Empire State.

The Empire State Building is an example of a transformed shape. The original shape is a square, but the architects transformed it into a triangle by adding a spire to the top. The spire adds height and visual interest to the building. It also helps to make the building more stable.

The use of transformed shapes in the design of the Empire State Building contributes to its overall aesthetic appeal. The building is both visually striking and structurally sound. It is a testament to the skill and ingenuity of the architects who designed it.

Here are some other examples of transformed shapes in buildings and structures:

* The Parthenon in Athens, Greece, is a rectangular building with a triangular pediment at each end. The pediments are decorated with sculptures that depict scenes from Greek mythology.

* The Eiffel Tower in Paris, France, is a wrought iron lattice tower that was built for the 1889 World's Fair. The tower is a transformed shape of a regular hexagon.

* The Gateway Arch in St. Louis, Missouri, is a stainless steel arch that spans the Mississippi River. The arch is a transformed shape of a catenary curve.

These are just a few examples of the many ways that transformed shapes are used in the design of buildings and structures. Transformed shapes can be used to add visual interest, create a sense of movement, or simply to make a building more structurally sound.

Step-by-step explanation:

The coordinates of the vertices for the image if the preimage is translated 3 units up is : A′(−3, 6), B′(0, 10), C′(−3, 3).

The correct option is (B)

If we are given the translated image of something, we need to work backwards given the translation rules. For example, if we have a general translation of (x +a, y +b), then to find pre-translation coordinates, we do: (x−a, y−b).

We have the Triangle ABC has vertices at A(−3, 3), B(0, 7), and C(−3, 0).

Now, let's consider the translation that moves the triangle 3 units up. This means that we need to add 3 to the y-coordinate of each vertex to get the coordinates of the image.

So, the coordinates of the vertices of the image triangle, let's call it A'B'C', will be:

A' = (-3, 3+3) = (-3, 6)

B' = (0, 7+3) = (0, 10)

C' = (-3, 0+3) = (-3, 3)

We can then multiply 4 by 14 to get 56. Finally, we add 56 to 63 which gives us the answer of 119. Therefore, the solution to the expression 63+48÷(23-11)×14 is 119.

The Taylor polynomial of degree 3 for sin(x) for x near 0 is,

sin (x) = x - 1/6 x³

The ratio is sin (x) / x = 1 - 1/6 x².

Limit is 1.

Given function is sin(x).

We have to find the Taylor Polynomial for sin (x).

We know that,

f(x) = sin(x), so f(0) = sin (0) = 0

f'(x) = cos (x), so f'(0) = cos (0) = 1

f''(x) = -sin (x), so f''(0) = sin (0) = 0

f³(x) = -cos (x), so f³(0) = -cos(0) = -1

Taylor polynomial is,

sin (x) = {[f(0) (x - k)⁰] / 0!} + {[f'(0) (x - k)¹] / 1!} + {[f''(0) (x - k)²] / 2!} + {[f³(0) (x - k)³] / 3!}

Here c = 0.

sin (x) = 0 + x + 0 + (-x³/6)

sin (x) = x - 1/6 x³

The ratio,

sin (x) / x = (x - 1/6 x³) / x = 1 - 1/6 x²

When x tends to 0 in the expression, 1 - 1/6 x², the value tends to 1 - 0 = 1.

Hence the required Taylor polynomial is sin (x) = x - 1/6 x³.

A line of reflection, also known as a line of symmetry, is a line that divides a figure into two congruent parts that are mirror images of each other.

When a figure is reflected across a line of reflection, every point on one side of the line has a corresponding point on the other side of the line that is equidistant from the line.

To determine the line of reflection for the given graph:

- Reflection across the x-axis: The line of reflection is the x-axis.

- Reflection across x = -6: The line of reflection is a vertical line passing through x = -6.

- Reflection across the y-axis: The line of reflection is the y-axis.

- Reflection across y = -6: The line of reflection is a horizontal line passing through y = -6.

Thus, the line of reflection is the perpendicular bisector of every segment joining a point to its image after reflection.
