When an absolute value is changed in the horizontal, <em>the units in change are inside the "bars"</em>, and are as follows: <em>left = positive, right = negative</em>.

Therefore, the equation is y = | x - 6.5 |.

Kevin is observing the population of the fish he put into a pond. He built a pond and populated it with 500 fish. The population

laila [671]

Here we will use exponential form, which is

$y = y_{0} e^{kt}$

Initial value, y0 = 500

Double of 500 = 1000

$1000 = 500e^{k*1}$

$2 = e^k$

$k= ln (2)$

Required equation is

$y=500e^{x ln2} \\ y= 500 (2)^x$

Alborosie

She would make $98.50 in 10 hours.

Explanation :

It was reported that in 2004, the mean net worth of families in a certain region was $470.2 thousand and the median net worth

Kobotan [32]

Answer:

Median.

Step-by-step explanation:

We have been given that in 2004, the mean net worth of families in a certain region was $470.2 thousand and the median net worth was $92.3 thousand.

We know that mean and median of a symmetric data set is equal.

We also know that when mean of a data set is greater than median, then the data set has a very large valued outlier.

Since mean net wroth of families is approximately 5 times more than median net wroth of families, this means that some of the families has very high net worth as outliers.

Since the net worth of families has very large outliers, therefore, I would prefer median as the appropriate measure of center as median is not affected by outliers.

A region R in the xy-plane is given. Find equations for a transformation T that maps a rectangular region S in the uv-plane onto

muminat

Answer:

$x = u\cos(v) , y = u \sin(v)$

Step-by-step explanation:

For that transformation you just have to use polar coordinates, notice that when you use polar coordinates the radius is constant when the angles varies and the angle is constant when the radius varies. Therefore your transformation would be just

$x = u\cos(v) , y = u \sin(v)$ .
