Answer:

4/15

Step-by-step explanation:

1/3 + 2/5

Use common denominator of 15

5/15 + 6/15 = 11/15

What fraction of the books ordered are fiction?

1 - 11/15

Use common denominator of 15

15/15 - 11/15 = 4/15

14\sqrt[]{6}i

1) Let's rewrite it into the z=a +bi form.

2) So we can write out the following noticing that i² =-1 as well as √-1=i

\begin{gathered} \sqrt[]{-1176}=\sqrt[]{-1}\cdot\sqrt[]{1176} \\ Factoring \\ \sqrt[]{-1}\cdot14\sqrt[]{6} \\ i\cdot14\sqrt[]{6} \\ 14\sqrt[]{6}i \end{gathered}

Note that in this number the real part "a" is equal to 0.

What is the vertex of the function x2 - 6x + 8 = 0?
RUDIKE [14]

<u>Answer: </u>

The vertex of the function \bold{x^{2} -6 x + 8 = 0}is (h,k) = (3 , -1)

<u>Solution: </u>

The vertex form of quadratic equation is generally given as,

f(x) = a(x - h)^{2} + k

Where h,k is the vertex of the parabola.

From question, given that x^{2}-6 x+8=0 .

we have to find the vertex of the function.

Let us first convert the given quadratic equation to vertex form (eqn 1)

x^{2}-6 x+8=0

x^{2}-6 x=-8

By adding “9” on both sides of equation, we get

x^{2}-6 x+9=-8+9

x^{2}-6 x+9=1

By using the identity (a-b)^{2}=a^{2}-2 a b+b^{2} ,the right hand side of above equation becomes,

(x-3)^{2}=1

(x-3)^{2}-1=0

Now,the equation (x-3)^{2}-1=0 is of the vertex form.

By comparing (x-3)^{2}-1=0 with a(x-h)^{2}+k

we get the values of (h,k)

a = 1; h = 3; k = -1

hence the vertex of the function x^{2}-6 x+8=0 is (h,k) = (3 , -1)
