There are 3x-2 trees planted in each row of a rectangular Parcel of land. If there are a total of 24x-16 trees planted and the p

4vir4ik [10]

Let's call the number of rows 'R' . (Clever ?)

There are (3x -2) trees in each row, and there are 'R' rows,
so the total number of trees is [ R times (3x-2) ].

But the problem told you that the total number of trees is (24x-16).
So
 R(3x - 2) = (24x - 16)

For a quick, happy ending, how about factoring '8' out of the right side:

 R(3x - 2) = 8(3x - 2)

Is it jumping out at you yet ?
If not, then divide each side by (3x - 2) :

  R = 8

There are eight (8) rows of trees.

Find the average rate of change f(x)=x^2−6x+8 when x2=1 and x1=3

sergeinik [125]

Answer:

Average rate of change for given function is: -2

Step-by-step explanation:

Given function is:

$f(x)=x^2-6x+8\\x_12= 1\\x_1 = 3$

In order to find the rate of change, we have to find the value of function on x1 and x2

So,

$f(x_1) = (3)^2-6(3)+8 = 9-18+8 = -1\\f(x_2) = (1)^2-6(1)+8 = 1-6+8 = 3$

The formula for finding the rate of change is:

$Rate\ of\ change = \frac{f(x_2)-f(x_1)}{x_2-x_1}$

Putting the values, we get

$=\frac{3-(-1)}{1-3}\\=\frac{3+1}{-2}\\=\frac{4}{-2}\\= -2$

Hence,

Average rate of change for given function is: -2

Which statement is false?

Zarrin [17]

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. 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. It is important to understand that media messages do not have a goal.

Did that answer your question?
