Given function:

The minimum value of the function can be found by setting the first derivative of the function to zero.


Solving for x:


Substituting the value of x into the original function:

Hence, the minimum value in the given range is (-1, -0.368)
You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7
Not exactly sure but I think it's false hope this helps
Use Pythagorean theorem
a^2 + b^2 = c^2
You know b = 7, c = 16
Plug in the values
a^2 + 7^2 = 16^2
a^2 + 49 = 256
a^2 = 207
a = 14.38749
Round to nearest tenth
Solution: a = 14.4 in.
