Answer:

Step-by-step explanation:
Let
j ------> the number
we know that
The square of a number is equal to multiply the number by itself
so
The square of j is

so
Two-fifths of the square of a number j is the same that multiply the fraction 2/5 by the square of j

The answer of this problem is that you have to multiply 6 times 5 so the answer is 30 units3
At start ( t = 0 nanoseconds ) :
E ( t = 0 ) = 2.645 J
E ( t = 1 ) = 6.290 J
E ( t = 1 ) : E ( t = 0 ) = 6.290 : 2.645 = 2.37
Also:
E ( t = 2 ) : E ( t = 1 ) = 14.909 : 6.290 = 2.37
E ( t = 3 ) ; E ( t = 2 ) = 35.335 : 14.909 = 2.37
Therefore, the formula for calculating the energy of the system is:
E ( t ) = 2.645 * 2.37 ^ t
The answer is 4) exponential growth.
C. because 2.25 X 3 = 6.75 and 6.75 X 3 is 20.25
Since we know 14, but we don't know the other number, we use a variable. To do that, we look at the problem, then we figure out the unknown. The unknown is: A number. We know 14. Since "Triple" means 3, we can put the exponent 3 by X.
Therefore, the answer is
.
