- 6( -  \frac{2}{3}  + 2x) \\  =  - 6( -  \frac{2}{3} ) +  - 6(2x) \\  = 4 - 12x \\  = 4(1 - 3x)
I cannot see the choices, but I hope this helps.

denpristay [2]
The probability of getting a piece of chocolate or a lollipop would be \frac{28}{35}. You can find this by first adding all of the values of the amount of chocolate, lollipops, and licorice. Then, add the value of the amount of chocolate and lollipops.

The mean of a set of data is 90. Five of the six data points are given as 92, 201, 54, 43, and 13. What is the value of the sixt
STatiana [176]
The first step is to multiply 90 x 6 = 540, this is because the data should have 6 terms and since the mean is 90 all terms should add to 540, then add the terms you already have 92 +201+54+43+13= 403 but you need to have 540 so the last number is the difference 540 - 403 = 137

Question
Kay [80]

Answer:

f(x)=2(x-2)(x^2+64)

Step-by-step explanation:

A standard polynomial in factored form is given by:

f(x)=a(x-p)(x-q)...

Where <em>p</em> and <em>q</em> are the zeros.

We want to find a third-degree polynomial with zeros <em>x</em> = 2 and <em>x </em>= -8i and equals 320 when <em>x </em>= 4.

First, by the Complex Root Theorem, if <em>x</em> = -8i is a root, then <em>x </em>= 8i must also be a root.

Therefore, we acquire:

f(x)=a(x-(2))(x-(-8i))(x-(8i))

Simplify:

f(x)=a(x-2)(x+8i)(x-8i)

Expand the second and third factors:

=(x+8i)x+(x+8i)(-8i)\\\\=(x^2+8ix)+(-8ix-64i^2)\\\\=(x^2)+(8ix-8ix)+(-64i^2)\\\\=x^2-64(-1)\\\\ =x^2+64

Hence, our function is now:

f(x)=a(x-2)(x^2+64)

It equals 320 when <em>x</em> = 4. Therefore:

320=a(4-2)(4^2+64)

Solve for <em>a</em>. Evaluate:

320=(2)(80)a

So:

320=160a\Rightarrow a=2

Our third-degree polynomial equation is:

f(x)=2(x-2)(x^2+64)
