Round48.073 to the nearest hundredth

Hunter-Best [27]

Answer:

48.07 (brainliest answer?)

Step-by-step explanation:

'7' is the hundredth figure

3 is not 5 or over so it stays the same

1. Write a polynomial function of least degree with rational coefficients so that P(x)=0 has the given roots.

mr Goodwill [35]

1. If a polynomial function with rational coefficients has -4 and 8 as roots, it means we can factor this polynomial this way :

(x - (-4))(x-8) = (x+4)(x-8) = x² - 8x + 4x - 32 = x² - 4x - 32

1x² - 4x - 32 is a polynomial function of least degree with rational coefficients that satisifies the given conditions. The leading coefficient here is 1, we call this a monic polynomial.

2. There may be something missing in the question here

3. We can use the factoring techniques to find the roots :

x^3 - 5x² + 9x - 45 let us group x^3 with -5x² and 9x with -45 :

(x^3 - 5x²) + (9x - 45) = x²(x - 5) + 9(x - 5)

We can notice now that there is a common factor : (x-5) this allows us to factor again by (x-5) :

Y = (x-5)(x²+9)

This is the maximum we can do on R, but on C the set of complex we can still factor again.

x² + 9 has a negative discriminant : Δ = b² - 4ac where b = 0 , a = 1, c = 9

Δ < 0, Δ = - 36

Applying the formulas for the roots x1 and x2 we get x1 = -3i, and x2 = + 3i

Y = (x-5)(x-3i)(x+3i)

So the solution is S = {5, 3i, -3i} the three roots of the function.

when a polynomial x^3-ax^2-2x+2a+6 leaves a remainder (a+2) when divided by (x-a), find the value of a.

Tatiana [17]

Answer:

$a = 4$

Step-by-step explanation:

We are given that the polynomial:

$\displaystyle x^3 - ax^2 - 2x + 2a + 6$

Has the remainder (a + 2) when divided by (x - a), and we want to determine the value of a.

Recall that from the Polynomial Remainder Theorem, when dividing a polynomial P(x) by a binomial (x - a), the remainder will be given by P(a).

Since the remainder is (a + 2) when divided by (x - a), P(a) must equal (a + 2):

$\displaystyle P(a) = a+2$

Substitute:

$\displaystyle (a)^3 - a(a)^2 -2(a) + 2a + 6 = a + 2$

Simplify and solve for a:

$\displaystyle \begin{aligned} a^3 - a^3 - 2a + 2a + 6 &= a + 2 \\ \\ 6 &= a+2 \\ \\ a &= 4\end{aligned}$

In conclusion, the value of a is 4.
