2528.5 centimeters is approximately 0.0253 kilometers.

To convert centimeters to kilometers, we first need to convert centimeters to meters, then meters to kilometers.

1 kilometer = 1000 meters

1 meter = 100 centimeters

So, to convert 2528.5 centimeters to meters, we divide by 100:

2528.5 cm / 100 = 25.285 meters

And to convert meters to kilometers, we divide by 1000:

25.285 m / 1000 = 0.025285 km

Therefore, 2528.5 centimeters is approximately 0.0253 kilometers.

The answer can be rounded to 4 significant figures, which is the number of significant figures in the original measurement of 2528.5 centimeters:

The largest force that can be supported before any member ruptures is 8, the maximum force that bar BC can support.

To solve this problem, we need to find the maximum force (stress) that each bar can withstand before rupturing.

This can be found using the stress-strain diagram.

For bar AB with a cross sectional area of 2.3 in^2, the maximum stress that it can withstand is given by the maximum slope of the stress-strain diagram, which is approximately 1.

For bar BC with a cross sectional area of 4 in^2, the maximum stress that it can withstand is given by the maximum slope of the stress-strain diagram, which is approximately 2.

Since the force (stress) is equal to the stress times the cross sectional area, the largest force that bar AB can support is given by 1 * 2.3 = 2.3 and the largest force that bar BC can support is given by 2 * 4 = 8.

The circumference of the circle is 2 * pi * 9 = 56.5 feet. So, the degree measure is (6/56.5) x 360 = 51.1 degrees. Rounded to two decimal places, the degree measure is 51.1 degrees.

To find the degree measure of an angle that subtends an arc of length 6 feet on a circle of radius 9 feet, use the formula: degree measure = (arc length / circumference) x 360 degrees.

The degree measure of the angle that would subtend an arc of length 6 feet on a circle of radius 9 feet can be found by using the formula:

degree measure = (arc length / circumference) * 360

The circumference of the circle is 2 * pi * 9 = 18 * pi

So, degree measure = (6 / (18 * pi)) * 360 = (6 / 18) * (360 / pi) = 60 / pi

To convert this to degrees, we can use an approximation of pi as 3.14, so

degree measure = 60 / 3.14 = 19.11

Rounding to two decimal places, the degree measure is 19.11, which can be rounded to 19.11 degrees.

The statement is false, as it is possible for three vectors to not span Rn but still lie on the same plane, such as the three vectors (1,1,1), (2,2,2), and (3,3,3), which all lie on a plane that passes through the origin.

(a) In order for three vectors un, U2, U3 to span Rn, all possible values of n must be 3 or greater. This is because three vectors can only span a 3-dimensional space or higher. Therefore, any n greater than or equal to 3 will work.

(b) Since {u, uy, u3} is a spanning set for Rn, then {u, u, + u2, u, -u3} is also a spanning set for Rn. This is because adding or subtracting any of the vectors in the original set will still form a set of three vectors that span Rn.

(c) This statement is always true. If three vectors ui, uy, u3 are linearly independent, then any linear combination of those three vectors (such as u,, u, + u2, u, -u3) will also be linearly independent.

(d) This statement is also always true. If three vectors ui, uy, u3 are linearly independent, then any linear combination of those three vectors (such as u,, u, + u2, u, -u3) will also be linearly independent.

The dimensions of the rug are: width is 15 feet length is 21 feet.

Let's call the width of the strip of floor around the rug "x". Then the width of the rug would be 25 - 2x, and the length of the rug would be 34 - 2x.

The total area of the rug should not exceed 360 square feet, so we can set up an equation to represent this:

(25 - 2x)(34 - 2x) = 360

Expanding and simplifying the left-hand side:

25 × 34 - 2 × 25 × x - 2 × 34 × x + 4 × x² = 360

850 - 118x + 4x² = 360

4x² - 118x+ 490 =0

Now we have a quadratic equation that we can solve using the quadratic formula or by factoring. Either way, we find that x = 24.5 or x = 5. Since x represents the width of the strip of flooring, x must be positive. Therefore, x = 5 is the solution.

So the width of the strip of flooring is 5 feet, and the dimensions of the rug are:

The Taylor expansion of cos(x) around x=0 is [tex]cos(x) = 1 - (x^2/2!) + (x^4/4!) - (x^6/6!) +[/tex]......

We would use this expansion to calculate the cosine of a given angle with an error tolerance of 0.1%.

To do this, we must first write a function taylorcosine() which takes two arguments: the angle (in radians) and the relative percentage error. The function should then return two values: the Taylor approximation for the cosine of the angle, and the number of terms required in the Taylor series to reach this level of error.

For example, if we want to find the approximate value of cos(3π) with an error tolerance of 0.1%, we would call the function as follows:

[tex]val, nsteps = taylorcosine(3π, 1e-3)[/tex]

To find the percentage relative error, we must multiply the relative error by 100.

We can also use the bisection method to determine the roots of a function. To do this, we must write a function myBisection() which takes

three arguments: the function handle, an array containing the lower and upper limits of the starting interval, and the maximum allowable relative error. The return value of the function is the estimate of the root.

For example, if we want to find the root of f(x) = x^2 - 3x + 2, with an initial bracket of [1.3, 0] and an error tolerance of 1%, we would call the function as follows:

root = [tex]myBisection(f, [1.3, 0], 1%)[/tex]

The error is defined as the absolute value of the ratio of the difference between the old and the new estimates of the root and the new estimate of the root.

Error = [tex]|x_new/x_new - x_old|/x_new[/tex]

Step-by-step explanation:

For the first volume problem involving the rectangular pyramid, the normal volume formula is V = 1/3 (l)(w)(h).  Since all 3 dimensions are being multiplied by 1/2, this involves multiplying the original formula by (1/2)(1/2)(1/2) which, put together, is multiplying by 1/8, so the volume will be 1/8 of what it was with the original dimensions.

The volume of the rectangular pyramid is multiplied by ( 1/8 )

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the length of the rectangle be L

Let the width of the rectangle be W

Let the height of the rectangle be H

Now , the volume of rectangle be V = L x W x H

And , when the length , width and height are multiplied by ( 1/2 ) , we get

L' = L/2

W' = W/2

H' = H/2

A ratio is simply the relation between two amounts showing how many times a value is contained within another value.

From the diagram,

Side A of the small triangle = 10

Side B of the small triangle = x + 2

Side A of the Big triangle = 10 + x

Side B of the big triangle = x + 14

Hence;

Ratio of Side A to Side B of the small triangle = 10 / x + 2

Ratio of Side A to Side B of the Big triangle = 10 + x / x + 14

Since the triangle area similar, equate the two ratio and solve for x.

10 / ( x + 2 ) = ( 10 + x ) / ( x + 14 )

Cross multiply

10( x + 14 ) = ( 10 + x )( x + 2 )

Expand using FOIL method

10x + 140 = 10x + 20 + x² + 2x

10x + 140 = x² + 12x + 20

x² + 12x + 20 = 10x + 140

x² + 12x + 20 - 10x - 140 = 0
