There's no cube shown but we can guess the diagonal is the long diagonal.  

In a rectangular parallelpiped (aka a box) with dimensions a × b × c the long diagonal x satifies a 3D version of the Pythagorean Theorem,

x² = a² + b² + c²

In a cube a=b=c

x² = 3a²

x = a√3

Answer: 7√3

What is the slope of the line which passes through (−2, 0) and (0, 4)?
riadik2000 [5.3K]
Slope is rise/run, or y/x. So y from zero to 4 is 4, and x from -2 to zero is 2. and 4/2=2, so the slope is 2

The frequency of a radio wave varies inversely with its wavelength. If a 100-meter wave has a frequency of 3,000 kilohertz, what
Tanzania [10]

Let the frequency be 'f' and wavelength be 'w'

f\alpha \frac{1}{w}

f =  \frac{k}{w} , k\neq 0

w= 100 m and f = 3,000 kilohertz

Plug in the above values to find k

3000 = \frac{k}{100}

To find k, multiply both side by 100

3000(100) = k

k = 300,000

So equation becomes,

f =  \frac{300,000}{w}

w= ? f = 500 kilohertz

500 = \frac{300,000}{w}

w = \frac{300,000}{500}

w = 600 m
