True or False? If true, give a brief reason why; if false, give a counterexample. (Assume in all that V and W are vector spaces.)
a. If T : V → W is a linear transformation, then T(0) = 0.
b. Let V be a vector space with basis α = {v1, v2, . . . , vn}. Let S : V → W and T : V → W be linear transformations, and suppose for all vi ∈ α, S(vi) = T(vi). Then S = T, that is, for all v ∈ V , S(v) = T(v).
c. Every linear transformation from R3 to R3 has an inverse. That is, if T : R3 → R3 is a linear transformation, then there exists a linear transformation S : R3 → R3 such that S(T(v)) = T(S(v)) = v for all v ∈ R3 .
d. If T : Rn → Rm is a linear transformation and n > m, then Ker(T) 6= {0}.
e. If T : V → W is a linear transformation, and {{v1, v2, . . . , vn} is a basis of V , then {{T(v1), T(v2), . . . , T(vn)} is a basis of W.

B.F., age 28, presents with diarrhea and abdominal pain. He says he feels weak and feverish. His symptoms have persisted for 5 days. He tells you he has 8 to 10 bowel movements each day, although the volume of stool is only about “half a cupful.” Each stool is watery and contains bright-red blood. Before this episode, he had noticed a gradual increase in the frequency of his bowel movements, which he attributed to a new vitamin regimen. He has not traveled anywhere in the past 4 months and has taken no antibiotics recently. His medical history is significant for UC; his most recent exacerbation was 2 years ago. He is taking no medications except vitamins.
Examination findings include a tender, slightly distended abdomen. His BP is 122/84 sitting, 110/78 standing; HR 96 bpm; and temperature of 100°F. Otherwise, physical findings are unremarkable. Laboratory study results reveal hemoglobin 12 g/dL; hematocrit 38%; white blood cell count 12,000/mm3; platelet count 242k; sodium 132; potassium 3.6. All other study results are within normal limits. The most recent colonoscopy findings (4 years ago) revealed granular, edematous, friable mucosa with continuous ulcerations extending throughout the descending colon.

Hello,
***We have to print the second list backward while interleaved with the first list in normal order.***
its PYTHON language.
Please refer the below example. Bold are the inputs that the user enters. In here the user input words and much as he wants and when he enter STOP, it stops and he is asked to enter more words.(second words count equals to the word count he inputs in the first phase)
Enter words, STOP to stop. Ok
Enter words, STOP to stop. we're
Enter words, STOP to stop. this
Enter words, STOP to stop. STOP
Ok. Now enter 3 other words.
Word 0: again?
Word 1: doing
Word 2: wait
Now I will magically weave them more weirdly!
Ok
wait
we're
doing
this
again?
PS : I have done it actually but the I have a problem getting the last output.(how to merge the 2 lists.) It only prints the words in input order.
MY CODE :
firstlist = []
c=0
stop = False
while not stop:
a = input("Enter words, STOP to stop. : ")
if a == "STOP":
stop = True
else:
c+=1
firstlist.append(a)
print("Okay. Now enter other " + str(c) +" numbers!")
for i in range(c):
v = input('Enter word ' + str(i+1) + ': ' )
firstlist.append(v)
print("I'm going to magically weave the words!!")
for x in firstlist:
print(x)
Please help.

Using Extrinsic and Intrinsic Rewards to Motivate Student Achievement
Objectives
Introduction
The purpose of this exercise is to explore the use of rewards in motivating student achievement. There are two types of rewards—extrinsic and intrinsic—that can be used to fuel student motivation. Extrinsic motivation drives people’s behavior when they do things in order to attain a specific outcome. Extrinsic motivation is the payoff a person receives from others for performing a particular task. For students, these rewards include things like grades, getting better jobs, verbal recognition from peers and professors, academic scholarships, and admittance to honorary societies and associations. In contrast, intrinsic motivation is driven by positive feelings associated with doing well on a task or job. Intrinsic rewards are self-granted; the payoff comes from pleasing yourself.

Determine, for a given graph G =V,E and a positive integer m ≤ |V |, whether G contains a clique of size m or more. (A clique of size k in a graph is its complete subgraph of k vertices.)
Determine, for a given graph G = V,E and a positive integer m ≤ |V |, whether there is a vertex cover of size m or less for G. (A vertex cover of size k for a graph G = V,E is a subset V⊆ V such that |V| = k and, for each edge (u, v) ∈ E, at least one of u and v belongs to V.)
a.)Describe the process of showing that a problem is NP complete
b.) given that the CLIQUE problem is NP complete. show that the VERTEX COVER problem is NP complete.
