5 0

For this case we must find the product of the following expression:

8y ^ 3 (-3y ^ 2) =

We have to by law of signs of multiplication:

+ * - = -

Also, by definition of multiplication of powers of the same base, we put the same base and add the exponents, then the expression is rewritten as:

-24y ^ {3 + 2} =\\-24y ^ 5

Answer:

-24y ^ 5

Identify the vertex, roots, and equation of the function below.
spayn [35]

The equation of a parabola in vertex form, is:

y=a(x-h)^2+k

Where <em>(h,k)</em> are the coordinates of the vertex.

From the given graph, notice that the coordinates of the vertex are:

(5,6)

The roots are the values of <em>x</em> where the graph crosses the x-axis. In this case, the graph crosses the x-axis at the points <em>(4,0)</em> and <em>(6,0).</em> Then, the roots are:

\begin{gathered} x_1=4 \\ x_2=6_{}_{} \end{gathered}

Substitute the values of the vertex into the equation of the parabola in vertex form:

y=a(x-5)^2+6

To find the value of <em>a</em>, substitute <em>(x,y)=(4,0)</em>:

\begin{gathered} 0=a(4-5)^2+6 \\ \Rightarrow0=a(-1)^2+6 \\ \Rightarrow0=a+6 \\ \Rightarrow-6=a \\ \Rightarrow a=-6 \end{gathered}

Therefore, the equation of the parabola is:

y=-6(x-5)^2+6
