. Let A =     −2 −1 −1 2 1 0 0 2 5 3 0 3     . (a) Enter A into MATLAB and use MATLAB to compute the dot product of the first column of A with its second column. Also compute the dot product of the third column with itself. (See guide for how to extract a column from a matrix.) (b) Compute the matrix product AT A. (c) ? What is the relationship between the entries of AT A and the dot products of the columns of A? Make sure your answer is consistent with your computations. (d) ? What in general is the relationship between the entries of AAT and dot products of vectors associated to A? (e) Compute AAT and do at least two dot product computations to support your previous answer. (f) Let Q =   1/ √ 14 1/ √ 3 5/ √ 42 2/ √ 14 1/ √ 3 −4/ √ 42 3/ √ 14 −1/ √ 3 1/ √ 42  . Do a single matrix computation which shows that the columns of form an orthonormal set. (g) ? Explain carefully why your computation above shows that the columns form an orthonormal set. (h) ? Explain why the rows of Q must also form an orthonormal set.

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
