You were given the polynomial f(x)=3x^3+13x^2+19x+k and you know that f(-2)=0find k

eduard

Answer:

k = 10

Explanation:

The initial polynomial is:

$f(x)=3x^3+13x^2+19x+k$

If f(-2) = 0, then when we replace x by -2, the result will be 0. It means that we can write the following equation:

$\begin{gathered} f(-2)=3(-2)^3+13(-2)^2+19(-2)+k=0 \\ 3(-2)^3+13(-2)^2+19(-2)+k=0 \end{gathered}$

Therefore, we can solve for k as follows:

$\begin{gathered} 3(-8)+13(4)+19(-2)+k=0 \\ -24+52-38+k=0 \\ -10+k=0 \\ -10+k+10=0+10 \\ k=10 \end{gathered}$

So, the value of k is 10

What is the percent of change from 10 to 5?

NNADVOKAT [17]

Answer:

50% decrease

Step-by-step explanation:

$\dfrac{(V_2-V_1)}{|V_1|} \times 100$

$= \dfrac{(5 - 10)}{|10|} \times 100$

$= \dfrac{-5}{10} \times 100$

$= -0.5 \times 100$

$= -50\% \; \text{change}$

$= 50\% \; \text{decrease}$
