Determine the equation of the polynomial, p(x),in both factored and standard form.
melamori03 [73]

We can see that the graph touches x=-1 without crossing the x-axis (i.e. it is a double solution), and then there's another zero at x=2 (this time it's a crossing zero, so a single solution).

This leads, up to multiple, to the polynomial

p(x)=a(x+1)^2(x-2)

If we impose the passing through (0,4) we have

p(0)=4=a(1)(-2) \iff -2a=4 \iff a=-2

So, the polynomial is

p(x)=-2(x+1)^2(x-2)=-2 x^3 + 6 x + 4

Finally, to solve p(x), simply look at the graph, searching for the points, where the graph is below the x-axis. You can see that this happens only if x>2, so that's the solution to your question.

In a standard deck of playing cards, one-fourth of the cards are hearts.
makkiz [27]

Answer:

\sf D) \quad \dfrac{1}{64}

Step-by-step explanation:

\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}

Probability of drawing a heart from one deck:

\sf \implies P(heart)=\dfrac{1}{4}

Therefore, probability of drawing a heart from each of 3 decks:

\sf \implies P(heart)\:and\:P(heart)\:and\:P(heart)=\dfrac{1}{4} \times \dfrac{1}{4} \times \dfrac{1}{4}=\dfrac{1}{64}
