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

I do need help with this problem that includes pi. ^_^

Troyanec [42]

Solution:

Note that:

Circumference = 50.24 ft = 2πr = πd
Dia. = 16 ft.

Divide the diameter both sides.

50.24 ft = πd
=> 50.24/d ft = πd/d
=> 50.24/d ft = π

Substitute the diameter in the equation.

=> 50.24/16 = π (Option A)
