if k is a constant, determine and state the value of kids such that the polynomial k^2x^3-6kx+9 divisible by x-1

1 answer:

5 0

By the polynomial remainder theorem, $k^2x^3-6kx+9$ will be divisible by $x-1$ if the value of the polynomial at $x=1$ is 0.

$k^2(1)^3-6k(1)+9=k^2-6k+9=(k-3)^2=0$

which occurs for $k=3$ .

<span>I found this by first doing the calculations for the number of legs (26). First, I added the legs for the 3 beetles together to get 18 legs. Then I added the legs for 2 lizards (8) to the beetles’ legs to get 26 legs in total.To find the number of heads I added the number of lizard heads (2) and beetles heads (3) to get five heads. Then I added the 7 worm’s heads to the lizard and beetles heads to get 12 heads in total.</span>

Which equation does the graph represent?

Art [367]

Answer:

It is the second answer

Step-by-step explanation:

The standard form of an ellipse is

x^2/a^2 + y^2/b^2 or x^2/b^2 + y^2/a^2 = 1

If the x is the main axis we use the first form. If the y is the main axis we use the second form. We will use the second form.

our a is 3 and our b is 4

x^2/3^2 + y^2/4^2
