Answer:

f(0)=0

Step-by-step explanation:

The number in the parenthesis in a function are what you substitute for x, so do that for the problem:

f(x)=(1/2)(x) --> f(0)=(1/2)(0)

Then solve for f(0) by simplifying the other side of the equation:

f(0)=0

Which of the following is equivalent to the complex number -8(7i - 3i^2)
Leni [432]

Answer:  B) -56i - 24

This is the same as -24 - 56i

=============================================

Explanation:

The 'i' refers to the imaginary number \sqrt{-1}

In other words, i = \sqrt{-1}

Squaring both sides gets us i^2 = -1

So,

x = -8(7i - 3i^2)\\\\x = -8(7i - 3(-1))\\\\x = -8(7i + 3)\\\\x = -8(7i) -8(3)\\\\x = -56i -24 \ \ \text{ .... Answer: Choice B}\\\\x = -24 - 56i\\\\

The result is in the form a+bi where a = -24 is the real part and b = -56 is the imaginary part.

What is -4 2/3 as a decimal with work

The decimal equivalent is -4.666....

In order to find this, we need to start by just taking the whole number for itself.

2/3 = .666...

Now we simply put them together and get our answer.

-4.666...
