For f(x)=3x+1 and g(x)=x^2-6, find (f o g)(x)

Mathematics

Eddi Din [679]3 years ago

The answer is:  " <span>3x² − 17 " .
______________________________________</span>
f(x) = 3x + 1 ;
________________________________________________
If g(x) = x² − 6 ;

then:   (f o g)(x)  = f(x² − 6) = 3x + 1 ;

=  3(x² − 6) + 1  =  3x² − 18 + 1 ;

=  3x² − 17  .

A Pascal triangle is the triangular way of expanding a binomial. So the best way in expanding that function is thru Binomial Theorem and the expanded for of it is 8x^3+48x^2+98x+64

Answer:

  a.  (1.4, 2.6)

  b.  (3, 2)

Step-by-step explanation:

a. The circumcenter is the intersection point of the perpendicular bisectors of the sides of the triangle.

For points X(a, b) and Y(c, d), the perpendicular bisector of XY can be written as ...

  (c -a)(x -(c+a)/2) +(d -b)(y -(d+b)/2) = 0

Then the equation of the perpendicular bisector of MN is ...

  (-2-4)(x -(-2+4)/2) +(4-0)(y -(4+0)/2) = 0

  -6(x -1) +4(y -2) = 0

  3x -2y = -1 . . . .  divide by -2 and put in standard form

Similarly, the perpendicular bisector of NO is ...

  (0-(-2))(x -(0-2)/2) +(6 -4)(y -(6+4)/2) = 0

  2(x +1) +2(y -5) = 0

   x + y = 4 . . . . divide by 2 and put in standard form

So, the point of intersection is ...

  (3x -2y) +2(x +y) = (-1) +2(4) . . . . . add twice the 2nd equation to the 1st

  5x = 7 . . . . . . simplify

  x = 1.4 . . . . . . divide by 5

  y = 4-1.4 = 2.6 . . . . . find y from the second equation

The coordinates of the circumcenter are (1.4, 2.6).

__

b. The centroid is the average of the vertex coordinates.

  centroid = (A +B +C)/3 = ((1, 2) +(3, 4) +(5, 0))/3 = (1+3+5, 2+4+0)/3 = (9, 6)/3

  centroid = (3, 2)

What are the solutions of 3x2 - x + 4 =
o-na [289]

To do this, you must use the order of operations.

3·2=6

6+4=10

Now to solve (-)x.

Since -x comes in front of 4, you must make your equation:

-x+10

Nothing is written for x, so now, you have the answer.

-x+10
