Answer:

431

Step-by-step explanation:

When polynomial f(x) is divided by x-a, the remainder is f(a). Here, "a" is -3. We can compute f(-3) as ...

f(x) = ((x^2 -4)x^2 +4)x^2 -10 . . . . Horner form simplifies evaluation

f(-3) = ((9 -4)9 +4)9 -10 = 431

The remainder of the division is 431.

What are the leading coefficient and degree of the polynomial? <br> 20-w^9+2w^3+12w

Ilya [14]

I assume you want the leading coefficient because there is only 1.

The leading coefficient is always in front of the term with the greatest exponent.

Leading coefficient = -1.

The degree of this function is 9. It is a ninth degree polynomial function. Why 9? It is a 9th degree polynomial because 9 is the greatest power.

How many times smaller is 2 × 10^-10 than 4 × 10^-5

natta225 [31]

Answer:

200,000

Step-by-step explanation:

To find how many times smaller is smaller number than greater number, divide greater number by smaller number.

Greater number $=4\times 10^{-5}$

Smaller number $=2\times 10^{-10}$

Then

$\dfrac{\text{Greater number}}{\text{Smaller number}}\\ \\=\dfrac{4\times 10^{-5}}{2\times 10^{-10}}\\ \\=\dfrac{4}{2}\times \dfrac{10^{-5}}{10^{-10}}\\ \\=2\times \dfrac{1}{10^{-5}}\\ \\=2\times 10^5\\ \\=2\times 100,000\\ \\=200,000$
