Applying Inverse Properties In Exercise,apply the inverse properties of logarithmic and exponential functions to simplify the ex

pshichka [43]

Answer:

5x + 2

Step-by-step explanation:

Since logarithm has the following property:

If $f(x)=b^x$ and $g(x)=\log_bx$ ,

Then $fog=b^{\log_bx}=x$ and $gof=\log_bbx=x$

Therefore,

$e^{\ln(5x + 2)}=e^{\log_e(5x+2)}=5x+2$

Karen is starting a career as a professional wildlife photographer and plans to photograph Canadian Geese at one of the staging

balandron [24]

Answer:

$5000*0.816 = $4082

Step-by-step explanation:

It's a strange question, but based on the statement and the question it sounds like it's a poisson distribution:

* For 3 days she was able to get 2 good shots (<em>typical of that time of the year</em>)

* Good shots happen randomly

* Each day is independent of another

Let's call 'p' the probability that she makes a good shot per day

Let's call 'n' the number of days Karen is taking shots.

So, if in 3 days he got 2 good shots and that is typical at that time of the year, then the expected value for the number of good shots (X) is:

$E(x)=\frac{2}{3}$

For a Poisson distribution $E (x)=\lambda\\\lambda= np$

So:

$\lambda =\frac{2}{3}$

For a Poisson distribution the standard deviation is:

$\sigma = \sqrt{\lambda}\\\sigma = \sqrt{\frac{2}{3}}$

$\sigma = 0.816$ this is the standard deviation for the number of buentas taken.

So the standard deviation for income is the price of each shot per sigma

$5000*0.816 = $4082, which is the desired response.

The median player salary for a professional football team was $457,200 in 2000 and $1,342,676 in 2008. Write a linear equation g

Vesna [10]

Answer:

The linear equation giving the median salary y in terms of the year x is:

y = 110,684.5x + 457,200

Step-by-step explanation:

For calculating the linear equation first we need to calculate the slope of the equation represented with an m, the formula is the following:

$m=\frac{y_{2}- y_{1} }{x_{2}-x_{1}}$

As in the problem it is said, x will represent the time so:

x1 will be the initial year so x1=2000

x2 will be the final year so x2=2008

Now the salary will be represented with the y so:

y1 will be the salary for the year 2000 then y1 = $457,200

y2 will be the salary for the year 2008 then y2 = $1,342,576

Then replacing the values in the equation we will have the following expresión:

$m=\frac{1,342,676-457,200}{2008-2000} = \frac{885,476}{8}=110,684.5$

Now we have to replace this values in the following formula for linear equation

y-y1 = m(x-x1)

As they say that x represent 2000 as the initial year then when we replace we will have the following expresion

y - 457,200 = 110,684.5(x - 0)

y = 110,684.5x + 457,200

To verify our equation we can check for the salary in 2008 as it is 8 years after of 2000 x=8 then

y = 110,684.5 (8) + 457,200

y = 885,476 + 457,200 = 1,342,676
