Since it is given that the reduction in the amount of waste each week is linear, it is conclusive that these data are also in arithmetic sequence. First, determine the common difference (d)
d = (a10 - a5) / (10 - 5)
Subsituting the known values,
d = (30 - 40) / 5 = -2
To determine any term (at) of the arithmetic sequence,
at = a1 + (n - 1) x d
Solve for a1 by using either the given a5 or a10,
40 = a1 + (5 -1) x -2 ; a1 = 48
The equation becomes,
at = 48 + -2(n -1)

Answer:
Step-by-step explanation:
You have the following exponential expression:
You need to divide both sides of the equation by 2:
Now apply the function Natural logarithm to both sides of the function:
Note that now the exponential function is transformed into a logarithmic function.
By definition:
Because the base of the Natural logarithm is the Euler's number "e".
Then you can solve for "x":
