HELP PLEASE!!! I NEED THIS NOWWWWW!!

Mathematics
1 answer:
Ugo [173]3 years ago

Part A - linear functions change at a constant rate.. while exponential functions change at a constant percent rate... that sounds the same but it's not.  A linear function will go up (or down) the same amount when the time period is the same...  like up 1,000 more visitors every month... if this happens, when you subtract the visitors for month 10-month 9, you will get the same answer as when you subtract he visitors for month 9-month 8.  

An exponential function will go up by the same % when the time period is the same... so it'd be like if it went from 1,000 to 1,100 (that's up 100, which is 10% of 1,000) and then from 1,100 to 1,210 (that's up by 110, which is 10% of 1,100). If this happens you get the same answer when you divide the visitors for month 10 by the visitors from month 9 as you get when you divide the visitors for month 9 by the visitors from month 8.    (sometimes because of decimals you only get really really close to the same but that counts).

This one is exponential because dividing gets you around 2.09 every time

Part B

Since dividing # of visitors by the # from the month before gets you around 2.09 each time, we multiply that by 100 to get the % version of the decimal.

So that's 209%... but that's not how much it changes by or grows by... that's what it ends up.  It goes from itself (100%) to a bigger # (209%).. that's a 209-100 = 109% increase each month.



Part C

you need to think a little bit about what's going on in class.... becasue there are a bunch of different ways to do this. Sometimes you make an equation, sometimes you work backwards.


Here's one way... since multiplying visitors from week 8 by 2.09 gets you week 9 visitors.. and multipliying week 9 visitors by 2.09 gets you week 10... etc.... we can go backwards...

Week 7 visitors times 2.09 would equal the week 8 visitors

so,  w(2.09)=5.74

if we divide both sides by 2.09 we get w is equal to about 2.7464...  so the week 7 visitors is about 2.7464 (thousands) or 2,746.


Hope that helps

Identify the center and radius of a circle with equation (x+4)^2+(y-2)^2=36
Kitty [74]
In the equation of a circle in the form (x-h)^2 + (y-k)^2 = r^2, (h,k) is the center and r is the radius.

So, the center of the circle is at (-4,2) with radius 6 units.

An advertising agency that serves a major radio station wants to estimate the mean amount of time the station’s audience members
Flura [38]

Answer:

n=(\frac{1.645(45)}{5})^2 =219.18 \approx 220

So the answer for this case would be n=220 rounded up to the nearest integer

Step-by-step explanation:

Information given

\sigma = 45 represent the population deviation

ME = 5 represent the margin of error

The margin of error for the true mean is given by this formula:

ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}    (a)

And on this case we have that ME =5 and we are interested in order to find the value of n, if we solve n from equation (4) we got:

n=(\frac{z_{\alpha/2} \sigma}{ME})^2   (b)

The critical value for 90% of confidence interval now can be founded using the normal distribution. The significance level is \alpha=1-0.9=0.1 and the critical value would be z_{\alpha/2}=1.645, replacing into formula (b) we got:

n=(\frac{1.645(45)}{5})^2 =219.18 \approx 220

So the answer for this case would be n=220 rounded up to the nearest integer
