Answer:

Your answer is in of the following questions below in step by step explanation.

Step-by-step explanation:

I.   Logic

Are there "rules" or "laws" that govern proper reasoning?  Can we prove, mathematically, that a particular argument is valid?  To what extent can reasoning be automated?

1.   Statement (proposition):  a sentence that is either true or false, but not both.

Example.  Determine if each of the following sentences is a statement.

a.   5 + 3 = 7    

 

21 / 7 = 3    

 

c.   MIDN Miller is President of the United States    

 

d.  Ah,…the joy of SM242!    

 

e.  He is a midshipman  

 

MIDN Avworo has written C++ programs.    

 

Baltimore is the capital of Maryland.    

 

h.  3 * z < 9  

 

i.   Every even integer greater than 2 is the sum of two primes  

 

j.  This sentence is false.  

 

2.  Compound Statements:  a more complex statement composed of simpler statements.  The truth-value of a compound statement depends on the truth values of the simpler component statements.  The component statements in a compound statement are often referred to as statement variables.

 A compound statement usually consists of statement variables joined by logical connectives.

3.   Logical Connectives:  

Not (negation)  

Mathematical symbol:  ~

~p means "it is not the case that p"  where p is some statement.

Other notations: EMBED Equation.DSMT4  , EMBED Equation.DSMT4  

C++ notation:  

The negation of a statement has the opposite truth-value from the statement.  If p is true, ~p  is false.

The definition of negation is displayed in a truth table

p       ~p

F         T

T         F

And (conjunction)

Mathematical symbol:   EMBED Equation.DSMT4  

EMBED Equation.DSMT4    means “it is the case that p and q are true.”

C++ notation:  

The conjunction of two statements p and q is true when and only when both p and q are both true.

The definition of conjunction is displayed in a truth table

p    q       EMBED Equation.DSMT4  

F    F        

F    T        

T    F        

T    T        

Example

p:    MIDN Berrios is an officer

q:    MIDN

Given the equation 2x = 4y - 3 write another linear equation that would create a system that has the number of solutions listed
Harman [31]

Answer:

A. 2x-4y=\pi
B.  x=1

C. 2x-4y=3

Step-by-step explanation:

A. 2x-4y=\pi. Any number could work as long as the coefficients for x and y stays the same. You are basically imposing that the quantity 2x-4y (if you bring 4y to the LHS) is equal to both -3 AND \pi, or any number you like. But yesterday was 3/14 so let's pick a fun number!

B.  x=1 Or y=1. Or as long as you don't pick the same ratios of x and y you're golden. But x=1 is the easiest that comes to mind

C. 2x-4y=3. To get infinitely many solutions you just have to rewrite the equation again. Maybe move things around if you prefer, or multiply everything by a number you lile.

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!
Zolol [24]

Answer:

Step-by-step explanation:

Triangle DEF is a right angle triangle.

From the given right angle triangle,

DE represents the hypotenuse of the right angle triangle.

With ∠E as the reference angle,

EF represents the adjacent side of the right angle triangle.

DF represents the opposite side of the right angle triangle.

To determine EF, we would apply

trigonometric ratio

Cos θ = opposite side/hypotenuse. Therefore,

Cos 49 = EF/8

EF = 8Cos49 = 8 × 0.6561

EF = 5.2488

Rounding to the nearest tenth, it becomes 5.2
