I'm having a hard time with logic homework. i don't comprehend when i read the instructions in a book . the assignment is to finish this argument by utilizing inference rules . so i need to set up a truth table to figure how to do that ,right? this is the problem thus far.
c: d

! : ~g -> (a v b )
2: ~b
3: a -> d
4. ( ~g )

5: ( a v b) 1, 4 mp
6: a 2, 5 ds
7: d 3,6 mp (qed)
ok she gave me this and i know modus poen
dysjunction syllogism at least what they are anyway.
and of course we do the rest. this friend of mine knows how to do them but she didn't explain what she's working from to get the answers. my question is, is she just getting the answers by a truth table that has to be set up to a certain degree? or how is she doing it? by the way, logic is the course which is not in the selection below. i should also say she gave me the solution to this but she didn't tell me how to get it?

the answer is d. (1.2, -4.7) on edgn

hope this !

answer: f = 32.2m

step-by-step explanation: that is the answer

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
