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]
(c) Apical ischemia: h =[20.3, 0.2]
(d) Chronic obstructive pulmonary disease:h =[0.1, 20.0667]

Greg has walked miles
<em><u>Solution:</u></em>
Given that, Greg’s house is 0.8 miles from the library
Distance between house and library = 0.8 miles
Greg has walked of the distance
Therefore,
Distance walked = of the distance between house and library
Here "of" means multiplication
Thus we get,
Thus Greg has walked miles
