5 have no idea please help

<span>Let's analyze our choices:
1. Media messages may translate differently across different media. Let's see here, if a person is reading a newspaper, would they react differently than if they noticed a tweet by their friend online about presidential campaign ads? Yes, they probably would, so this statement is true.
2. When analyzing media, it is important to ask, "Does it work ". If a person told you that the sky is actually pink but Mary Poppins is actually a real person and just makes you think that the sky looks blue, and that they learned this because the news told them so, would you automatically believe them? Not really. :P Therefore option 2 is out of the way.
3. It is important to understand that media messages do not have a goal. HAH! People and messages always have a goal. I think we may have found our false statement, but just to be sure, let's take a look at our last statement.
4. People will perceive media messages differently. </span>Have you ever watched a debate and thought that one side did a better job than the other, and then your friend starts an argument with you as they think that's total baloney? This statement is true too.

This leaves the only false statement as 3. <span>It is important to understand that media messages do not have a goal.</span>

13. Write an equation for the given function given the amplitude, period, phase shift, and vertical shift.

Paul [167]

Answer:

$y=4sin(\frac{2\pi(t+\frac{4}{3}\pi ) }{4\pi } )-2$

Step-by-step explanation:

Let's start with the original function.

$y=a sin\frac{2\pi t}{T}$

We can immediately fill in the amplitude 'a' and period 'T' , as the question defines these for us, and provides values for 'a' and 'T', 4 and 4 $\pi$ respectively.

$y=4sin(\frac{2\pi t}{4\pi } )$

Now we only have phase shift and vertical shift to do. Vertical shift is very easy, you can just add it to the end of the right side of the expression. A positive value will shift the graph up, while a negative value will move shift the graph down. We have '-2' as our value for vertical shift, so we can add that on as so:

$y=4sin(\frac{2\pit }{4\pi } )-2$

Now phase shift the most complicated of the transformations. Basically, it is just movement left or right. A negative phase shift moves the graph right, a positive phase shift moves the graph left (I know, confusing!). Phase shift applies directly to the x variable, or in this case the t variable. To achieve a -4/3 pi phase shift, we need to input +4/3 pi into the function, because of the aforementioned negative positive rule. Here is what the function looks like with the correct phase shift:

$y=4sin(\frac{2\pi(t+\frac{4}{3}\pi ) }{4\pi } )-2$

This function has vertical shift -2, phase shift -4/3 $\pi$ , amplitude 4, and period 4 $\pi$ .

Desmos.com/calculator is a great tool for learning about how various parts of an equation affect the graph of the function, If you want you can input each step of this problem into desmos and watch the graph change to match the criteria.
