Answer:
As functions of a true variable, exponential functions are uniquely characterized by the very fact that the expansion rate of such a function (that is, its derivative) is directly proportional to the value of the function.
Step-by-step explanation:
Have a nice day hope this helps.
We will see that the solution in the given interval is: x = 0.349 radians.
<h3>How to solve equations with the variable in the argument of a cosine?</h3>
We want to solve:
cos(3*x) = 1/2
Here we must use the inverse cosine function, Acos(x). Remember that:
cos(Acos(x)) = Acos(cos(x)) = x.
If we apply that in both sides, we get:
Acos( cos(3x) ) = Acos(1/2)
3*x = Acos(1/2)
x = Acos(1/2)/3 = 0.349
So x is equal to 0.349 radians, which belongs to the given interval.

Step-by-step explanation:
In the first column, put days at the top and pounds at the bottom.
So Day 1 = 75 pounds, Day 2=150 pounds, Day 3 = 225 pounds, etc..
