OK so, your shape is a pentagon, how I like to do this and how I was taught to make it easier was divide the pentagon or what ever shape it is in to smaller easier shapes like triangles and rectangles. so this one looks like a diamond. You see the part where it say 4 inches and 8 inches, well we are going to cut it off there and find the area of that first with is 4x8=32
next we are going up to where it looks like a trapezoid and we are going to divide that into a triangle and a rectangle. Lets start with the rectangle 5.3x4= 21.2 now we move on to the triangle and the formula for that id A=1/2BxH but we can find 1/2 of the H instead of 1/2 of the B (B=base H=height) so 1/2 h = 2 so 2x2.7=5.4 now we add them all together:
5.4+32+21.2= 58.6 so the answer is:             58.6 in.^2

Use the svd() function in MATLAB to compute , the rank-1 approximation of . Clearly state what is, rounded to 4 decimal places.
Afina-wow [57]

Answer:

Here is the Matlab code.

Step-by-step explanation:

Matlab Code:

A = [1 2 2;3 4 5;6 7 8]\\[U,S,V] = svd(A)u1 = U(:,1)\\u2 = U(:,2)\\u3 = U(:,3)\\d1 = dot(u1,u2)\\c = cross(u1,u2)\\d2 = dot(c,u3)

d1 =-    5.5511e-17\\c =   -0.7172    0.6643   -0.2103\\d2 =        1  

Yes, since c = cross(u1,u2) is orthogonal to both u1 and u2. Hence is u3, thus the dot product with u3 is 1.

The sum of a number and its reciprocal is 5/2 Find the number and its reciprocal.
sergiy2304 [10]

Answer:

Step-by-step explanation:

Let the number be 'x'

Reciprocal = \frac{1}{x}

x+\frac{1}{x}=\frac{5}{2}\\\\\frac{x*x}{1*x}+\frac{1}{x}=\frac{5}{2}\\\\\frac{x^{2}+1}{x}=\frac{5}{2}

Cross multiply

(x² + 1) *2 = 5*x

2x² + 2 = 5x

2x² - 5x + 2 =0

Factorize the equation,

Sum = -5

Product = 4

Factors = -1 , -4

2x² - x - 4x + 2 = 0

x(2x - 1) - 2(2x - 1) = 0

(2x -1 )(x - 2) = 0

2x - 1 = 0               ; x -2 = 0

    2x =1                ; x = 2

       x = 1/2

Number = 2 , and its reciprocal = 1/2

On a sketch of a mural,3 inches represents one foot in the mural. A door in the sketch is 2 inches wide by 5 inches high. What i
grandymaker [24]

Answer:

Length of the door,                  <em> l</em> = 5 inches (<em>in</em>)

Width or Breadth of the door, <em>w</em> = 2 inches (<em>in</em>)

Perimeter                                   p = 2(l + w)

                                                   = 2( 5 + 2) <em>inches</em>

<em>                                                    = 2(5) inches + 2(4) inches</em>

                                                   = 10 <em>inches</em>  + 4 <em>inches</em>

                                                   = 14 <em>inches</em> or 14 <em>in</em>

  Step-by-step explanation:

The perimeter of a plane shape is the measurement of the length of its outside boundary, which means the distance around its edges.

The door in the sketch is the shape of a rectangle. the distance around the edge of the door is the sum of all the sides. The longer side of a rectangle is called the length and it is usually represented by letter<em> l</em> while the shorter side is known as width or breadth represented by letter <em>w</em> and<em> b </em>respectively. The perimeter is calculated by the formula 2(l + w). where l means the length and w represents the width.
