The weight of wrestler was 80 kg before the special diet
Step-by-step explanation:
Given function is:

We can substitute the values of t to find the weight after t number of months
When we have to find the initial weight , t has to be put equal to zero
So,

Hence,
The weight of wrestler was 80 kg before the special diet

Answer:
Step-by-step explanation:
Assume that the two prisms have bases of equal area.
Then the volume of the rectangular prism is V = (base area)(height).
The volume of the triangular prism is V = (1/3)(base area)(height)
We could compare the two volumes by creating the ratio inequality
(1/3) (base area)(t-height)
------------------------------------------
(base area)(r-height)
The triangular prism will have the greater volume for (1/3)((t-height) > r-height.
the slopes of these lines are equal when the determinant of the coefficient matrix is zero. Thus, for homogeneous systems we have the following result: A nxn homogeneous system of linear equations has a unique solution (the trivial solution) if and only if its determinant is non-zero.
5x + 4x = 720
9x = 720 (divide by 9)
X= 80
In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining)
Work:
5(80)= 400
