Best ResponseYou've already chosen the best response.0Medical Xrays, with a wavelength of about 10 ^10m, can penetrate completely through you skin.

Best ResponseYou've already chosen the best response.1Why don't you just multiply the wavelength of an Xray with 1000 in order to get the wavewength of a UV ray?

Best ResponseYou've already chosen the best response.1Not sure, but sounds like that it is only that.

Best ResponseYou've already chosen the best response.1beside we know that Xrays have a wavelength on about 100 nano meter.. if we take 10^10 meter and convert to nano meters.. we get 0.1 nm. Multiply that with 1000 and you get 100 nm.

Best ResponseYou've already chosen the best response.1if I had to guess, yes. Because we know the multiplication factor and one of the wavelengths. However if I were you I would calculate in nano meters. nano = 10^9

Best ResponseYou've already chosen the best response.0i got t bye mulitplyn 10^9*1000

Best ResponseYou've already chosen the best response.1I doubt that. Lets do it in the head: \[10^{9}*1000=10^{9}*10^{3}=10^{9+3}=10^{6}\]

Best ResponseYou've already chosen the best response.0oh ok so the answer is 10^6

Best ResponseYou've already chosen the best response.1it was not 10^9 but 10^10

Best ResponseYou've already chosen the best response.1\[10^{10} m*1000=10^{10} m *10^{3}=10^{10+3} m=10^{7} m\] \[10^{7} m * 10^{9} \frac{ nm }{ m }=100 nm\]

Best ResponseYou've already chosen the best response.0Consider the sequence 2, 6, 18, 54…. Let n= the term number in the sequence. Let A (n) = the value of the nth term of the sequence. 4. What is the common ratio of the sequence? Common ratio: 5. Complete each statement. a. A (1) =2=2*3^? b. A (2) =6=2*3=2*3^? c. A (3) =18=2*3*3=2*3^? d. A (4) =54=2*3*3*3=2*3^? 6. What is the relationship between the exponent of the base 3 and the value of n? 7. Complete the statement: A (n) = 2*3^?

Best ResponseYou've already chosen the best response.1I just ment i don't understand the way they put it... I'm not from the US so I have to translate the words back and forth, and when I do so I get something that don't make sence. All I can say is that you can discribe your function/seq as this: A(n)=2*3^n, n belongs to all whole positive numbers.

anonymous

Best ResponseYou've already chosen the best response.0you cant muliply anything by 80 to get 20 but 20*4 is 80

anonymous

Best ResponseYou've already chosen the best response.0oh so 80 tmes 1/4 is 20

Best ResponseYou've already chosen the best response.0so a. 6 b.18 c.54 d. 162 is that right

skullpatrol

Best ResponseYou've already chosen the best response.0The whole idea behind these type of questions is to answer: "what do I need to multiply by to get the next term"? and then continue using that number.

Best ResponseYou've already chosen the best response.0so what i got up there are those the right answers....

anonymous

Best ResponseYou've already chosen the best response.0actually it comes along with it, look back up with the one we just worked out and it says the common ratio, is the ratio times 1/4 or what
