Can someone please help me with my Question #29 of The Quadratic Relations for me please?
lara [203]

Answer:

Calculate the <u>first differences</u> between the y-values:

\sf 3 \underset{+1}{\longrightarrow} 4 \underset{+3}{\longrightarrow} 7 \underset{+5}{\longrightarrow} 12 \underset{+7}{\longrightarrow} 19

As the first differences are <u>not the same</u>, we need to calculate the <u>second differences</u>:

\sf 1 \underset{+2}{\longrightarrow} 3 \underset{+2}{\longrightarrow} 5 \underset{+2}{\longrightarrow} 7

As the second differences are the <u>same</u>, the relationship between the variable is quadratic and will contain an x^2  term.

--------------------------------------------------------------------------------------------------

<u>To determine the quadratic equation</u>

The coefficient of x^2  is always <u>half</u> of the <u>second difference</u>.

As the second difference is 2, and half of 2 is 1, the coefficient of x^2 is 1.

The standard form of a quadratic equation is:  y=ax^2+bx+c

(where a, b and c are constants to be found).

We have already determined that the coefficient of x^2 is 1.

Therefore, a = 1

From the given table, when x=0, y=12.

\implies a(0)^2+b(0)+c=12

\implies c=12

Finally, to find b, substitute the found values of a and c into the equation, then substitute one of the ordered pairs from the given table:

\begin{aligned}\implies x^2+bx+12 & = y\\ \textsf{at }(1,19) \implies (1)^2+b(1)+12 & = 19\\ 1+b+12 & = 19\\b+13 & =19\\b&=6\end{aligned}

Therefore, the quadratic equation for the given ordered pairs is:

y=x^2+6x+12

Vector a = 3i + mj, vector b = 2i - nj and vector c = ni + 8j. If a and b is perpendicular to each other and b and c are paralle
Tatiana [17]

May be you know it or not a two dimensional vector can be represented by a complex number.Why i have written this statement you will just know when you will see its solution

a = 3i + mj and  b = 2i - nj are perpendicular to each other ,so their dot product

will be zero.

i.e a.b = 0\\(3i + mj) .(2i - nj)=0\\6-mn=0\\mn=6j

vector b = 2i - nj and vector c = ni + 8j are parallel to each other.2i - nj = k (ni + 8j)2/n = -n/8n^{2} =-16n=4ij

mn = 6

so m=6/4i

m=3/2i

m=3i^{4}/2i

m = 3i^{3}/2

m= -3i/2 as(i^{4} =1, i^{3} = -i[/tex][/tex]

Derive a Boolean function f(x, y, z) that yields a 1 when exactly two of the three input variables are 0.
Rudiy27

Answer:

The notation from analyzing the Karnaugh map is:

F(X,Y,Z) = X'Y'Z + X'Z'Y + Y'Z'X

With logical functions would be:

F(X,Y,Z) = (NOT(X AND Y) AND Z) OR ((NOT Z) AND (X XOR Y))

Step-by-step explanation:

You can reduce the logical function with a Karnaugh map, like the attached, notice the gray coding notation, to assure only one variable change at each cell.
