The answer you are looking for is B, there is a small chance of the event occurring. <span />
-6,-2,-1,3,4 that's it then you're done
We have been that frequency (y) varies inversely with wavelength (x).
We know that two inversely proportional quantities are in form 
, where a is inversely proportional to b and k is constant of variation.
Our required equation would be 
.
To find frequency of blue light, we will substitute 
and 
in our equation as:
Therefore, the frequency of blue light is 764.
Answer:
4 x (b+2)
Step-by-step explanation:
Jesus is king :)
Let, the speed of boat = x
Speed of current = y
So, x + y = 280/7
x + y = 40 ---- first equation
x - y = 280/14
x - y = 20
x = 20 + y
Substitute this value of x in first equation,
20 + y + y = 40
2y = 40 - 20
y = 20/2
y = 10
Substitute this in first equation,
x + 10 = 40
x = 30
In short, Speed of Boat = 30 mph, & speed of current = 10 mph
Hope this helps!
