Vectorcardiography Suppose the voltage vector of a healthy heart is given by [0.3, 20.2]. Cardiac abnormalities result in change

s to this vector. Each abnormality can be viewed as a change of a healthy heart voltage vector into a pathological voltage vector through matrix multiplication. For each of the following heart pathologies, find a matrix that produces the pathological voltage vector from a healthy voltage vector. (a) Left anterior hemiblock: h =[0.3, 0.2], (b) Left posterior hemiblock: h =[20.3, 20.2]
(c) Apical ischemia: h =[20.3, 0.2]
(d) Chronic obstructive pulmonary disease:h =[0.1, 20.0667]

Find the exact value of sin 5pi/4
AURORKA [14]

The exact value of sin 5π/4 is 0. 0677

<h3>How to find the value</h3>

It is important to note that π = 3. 142

Let's find sin 5π

Substitute the value

sin 5π = sin (5 × 3. 142) = sin 15. 71

= \frac{sin 15. 71}{4}

Find the sine of the number

= \frac{0. 27076}{4}

= 0. 0677

Thus, the exact value of sin 5π/4 is 0. 0677

You are an engineer for a company that produces shipping boxes. The boxes that are made on one machine are all in the shape of a
Sidana [21]

Answer:

Step-by-step explanation:

Draw a picture of a cube and label the cube's side length, s. Prior to placing your order for more cardboard, tape, packing material, etc. your boss asked you to determine each of the following: a. Write an expression to determine the surface area of a cube-shaped box, SA, in terms of its side length, s (in inches).

The surface area of a cube of side length s is A = 6s^2; there are 6 sides each of area s^2.

If s is measured in inches, then A = 6x^2 inches^2.

b. Define a formula to determine the volume of a cube-shaped box, V, in terms of its side length, s, (in inches). Preview What are the units for the cube's volume?

The formula for the volume of a cube is V = s^3.  In this case, V is measured in inches^3.

c.  Given the formula for determining the volume of a 4 sphere is V = ar atrs, 3 (This is incorrect; the formula in question, for the volume of a sphere of radius r is V = (4/3)(pi)r^3.           (1) We can solve this formula for r^3, and then for r:

                                                  3V

3V = 4(pi)r^3 becomes r^3 = ------------

                                                 4(pi)

and so the formula for the radius of a sphere whose volume is 87 inches^3

is

     ∛(3V)        ∛3*87 in^3

r = ------------ = ------------------

      ∛(4pi)        ∛(4pi)

(2) The volume of the sphere when r = 5.9 in is:

                                                     4(3.14)      205.38 in³

(4/3)(pi)r^3 = (4/3)(pi)(5.9 in)³  =   --------- = --------------------- = 67.46 in³

                                                         3                 3

         

(3) V = (4/3)(pi)r³    

     Please share the possible answer choices.  Basically, you must find the volume twice:  once for a radius of 4 in and once for a radius of 2 in.  Then subtract the smaller from the larger.  The numerical result is the desired answer.

Pam is taking a train from the town of Rome to the town of Florence. Rome is located 40 miles due west of the town of Paris. Flo
tankabanditka [31]

Answer:

Pan is closest to Paris when she gets to Florence when she is 35 miles away

Step-by-step explanation:

With Paris at (0,0), Rome is 40miles west which is on the negative x axis.

Florence is 35 miles closer (east to Paris) so we have -45 + 35 = -10

and 55 mikes north of Rome which is on the positive y-axis. So Florence is at point (-10,55)

The distance between the two points Florence and Paris is √(x2 - x1)^2 + (y2 - y1)^2

x1 = 0, y1 = 0

x2 = -10, y2 = 55

So we have

√(-10-0)^2 + (55-0)^2

= √(-10)^2 + (55)^2

= √ 100 + 3025

= √3125

= 55.9 mikes from Paris

Pam is closest to Paris when she gets to Florence when she is 35 miles away
