15(n)=225 Divide both sides by 15

n=15

6^3*6^6*6^4)/(6^2*6^3*6^3)

Add the exponents of the top number=13

Add the exponenys of the bottom number=8

Then subtract them from each other=13- 8=5

The final answer is:6^5=7,776 which your answer.

Wavelength=Speed of light/Frequency

6.365 X 10^-10=2.99792458 X 10^8/F

F=2.99792458 X10^8 / 6.365 X 10^-10

F=4.71 X 10^17 Hertz

Alan:Please verify this.

Your answer is:41 2^(4/5)=71.3851461...

F=9.84 X 10^-9 m/sec^2

It is =2.236.....etc.

The answer to your question is:

=0

18 to 24   =  3 / 4

14:42  =    1 / 3

15 cents to 18   =  5/6

20 inches to 2 feet  =   20 inches to 24 inches  =   5/6

3 weeks to 10 days  = 21 days to 10 days   =  21/10

I think this question was answered yesterday, here.........http://web2.0calc.com/questions/compare-the-january-2014

No numbers are posted to work with........????

All real numbers.....we can put any value in for "x"

Sorry....my browser  can't access these files......????

10. If there is 7 sticks and 3 sticks, and you put the sticks together and count it, you will get 10 sticks. good luck, stupid guy.

CierDreaj.....if the funnel is 20 cm wide.....its radius would be 1/2 of that = 10cm

So....the volume of the funnel =  (1/2)pi (r^2) h =  (1/2)pi (10^2)(25)  = [2500/3] pi cm^3

10 = |-8q| + 1  subtract 1 from each side

9 = l -8q l       and we have two equations here

-8q = 9              -8q = - 9     

divide both sides by -8

q = -9/8      and        q = 9/8

At number 4 what about the 20cm widht at the top 

Just one question how does cube turns to square and the equation for R. Thank you so much sir you are a big help

what is 1/2 (sqrt of 65) (sqrt of 65)

sqrt(65) X 1/2

8.06226 X 1/2=4.03113.......etc.

1/2 (sqrt of 65) (sqrt of 65)  =  (1/2) 65   = 65/2  = 32.5

Their product=737,280

Geometric mean=5.41319....etc.

4x+6=175x-98

175x - 4x=-98 - 6

171x=104

x=-104/171

4x+6=175x-98  add 98 to both sides    subtract 4x from both sides

104 = 171x      divide both sides by 171

104/171  = x

This function  has no inverse because it is not one- to-one

However......if we restrict the domain of the original function, we can get two separate inverses

y = 9x^2     divide both sides by 9

y/9 = x^2   take the pos/neg square roots of both sides

[pos/neg] sqrt( y/9)  = x   exchange x and y

[pos/neg] sqrt( x/9)  = y  = f^-1(x)

If the domain of the original function is from (-inf, 0), then neg sqrt(x/9)  is the inverse

If the domain of the original function is from (0, inf), then pos sqrt(x /9)  is the inverse

[ BTW, the origin point (0, 0)  could belong to either inverse function ]

128= (1/2)(b)(32) simplify

128 = 16b       divide both sides by 16

128 / 16 = b = 8

Poorly worded question.....hard to know exactly what they want.  If you're in elementary or perhaps  junior high, I'd go with CPHIL. If you're in Engineering Economics in college or the real world, I'd go with #6
