Solve each equation by finding all roots x^4-16=0
Alexandra [31]
Add both sides by 16
so you'll have x^4 =16
take the 4th root of both sides and you'll get x=  2

Divide.<br><br> (6x^2+36x+35)/(x+5)<br><br> Your answer should give the quotient and the remainder.
zheka24 [161]

Answer:

6x+6+\frac{5}{x+5}

Step-by-step explanation:

When we divide polynomials by polynomials with more than one term, we use long division or factorization to simplify.

This polynomial isn't easily divided after factorization so we will use long division. And we will use the remainder theorem to write any remainder.

\frac{(6x^2+36x+35)}{(x+5)}

We start long division by finding what multiplies with x+5 to get  6x^2+36x. This is 6x.

So 6x(x+5)=6x^2+30x. We have 6x left as a remainder from 36x.

We now divide x+5 into 6x+35. What multiplies with x+5 to get 6x+35? 6.

So we have 6x+6 as our answer so far and after we multiply 6(x+5)=6x+30 we will have a final remainder of 5.

We write our answer as 6x+6+\frac{5}{x+5}.

Find f(x) and g(x) so that the function can be described as y = f(g(x)). y = Four divided by x squared. + 9
Igoryamba

•   Interpretation I:

Find f and g, so that

                           4
(f o g)(x)  =  —————
                       x² + 9


Well, there is more than one possibility.

                                                     4
For instance, It can be:  f(x)  =  ——  and  g(x) = x² + 9,
                                                     x


and then you have

                          
(f o g)(x)  =  f[ g(x) ]

                         4
(f o g)(x)  =  ————
                       g(x)


                         4
(f o g)(x)  =  —————        ✔
                      x² + 9

                                                                                    4
Another possibility for that composition:   f(x)  =  —————  and  g(x) = x²,
                                                                                 x + 9

and for those, you get

(f o g)(x)  =  f[ g(x) ]

                             4
(f o g)(x)  =  ———————
                     [ g(x) ]² + 9

                           4
(f o g)(x)  =  —————          ✔
                       x² + 9


As you can see above, there are many ways to find f and g, so the composition of those is  (f o g)(x) = 4/(x² + 9).

—————

•  Interpretation II:

Find f and g, so that

                      4
(f o g)(x)  =  ——  +  9
                      x²

                                                            4
It can be:   f(x) = x + 9  and  g(x)  =  ——
                                                            x²

and then you have

(f o g)(x) = f[ g(x) ]

(f o g)(x) = g(x) + 9

                     4
(f o g)(x)  =  ——  +  9
                     x²

                                                                             2
or it could be also:   f(x) = x² + 9  and  g(x)  =  ——
                                                                             x


and you have again

(f o g)(x) = f[ g(x) ]

(f o g)(x) = [ g(x) ]² + 9

(f o g)(x) = [ 2/x ]² + 9

(f o g)(x) = (2²/x²) + 9

                      4
(f o g)(x)  =  ——  +  9          ✔
                     x²


As you can see above, there are many ways to find f and g, so the composition of those is  (f o g)(x) = (4/x²) + 9.


I hope this helps. =)

Can anyone help me on the last question?
Novosadov [1.4K]

Answer:

<h2>           0.7</h2>

Step-by-step explanation:

A' is everything what is not A

So:

    A' = {9, 10, 11, 12, 13, 15, 16}

Number of ways it can happen: |A'| = 7

Total number of outcomes: |Ω| = 10

Probability of an event happening:

                                         \bold{P(A')=\dfrac{|A'|}{|\Omega|}=\dfrac7{10}=0.7}

Separate the x- and y-values with a comma.<br> X=-3+y<br> 26x - 5y = 6
labwork [276]

Answer:

The solution of the given system is (x,y) = (1,4)

Step-by-step explanation:

Here, the given system of equation is:

x  = -3 + y

26 x - 5 y =  6

Now, substitute x  = -3 + y in the second equation , we get

26 x - 5 y =  6  ⇒   26 (-3 + y) - 5 y =  6

or, 26(-3)  + 26(y)  - 5y = 6

⇒ - 78 + 26 y - 5y = 6

⇒   21 y =  84

⇒  y = 84 / 21 = 4   or ,   y =  4

So x  = -3 + y  =  -3 + 4 = 1

Hence, the solution of the given system is (x,y) = (1,4)
