Is the following conditional true?

2 answers:

7 0

Yes, it is true. Ex. 3 x 9 = 27, 2 + 7 = 9.

If you happen to have a larger number say, 639, you might have to add the digits together multiple times before you have your answer so, 6 + 3 + 9 = 18, then 1 + 8 = 9, so it is divisible by 9.

If f(x) = kx^3+ x^2 − kx + 2, find a number k such that the graph of f contains the point (k, -10)

Elina [12.6K]

If we write $k$ where we see $x$ in the equation and set the result equal to $-10$ , we get the result.

$f(k)=k(k)^3+k^2-k(k)+2$
$=k^4+k^2-k^2+2$
$=k^4+2=-10$
$k^4=-12$
$k_{1}=\sqrt[4]{3}(-1-i)$
$k_{2}=\sqrt[4]{3}(-1+i)$
$k_{3}=\sqrt[4]{3}(1-i)$
$k_{4}=\sqrt[4]{3}(1+i)$
