Answer:
to make it perpendicular the slope as to be -5 (opposite reciprocal of the original)
Answer:
Only option B is correct, i.e. all real values of x except x = 2.
Step-by-step explanation:
Given the functions are C(x) = 5/(x-2) and D(x) = (x+3)
Finding (C·D)(x) :-
(C·D)(x) = C(x) * D(x)
(C·D)(x) = 5/(x-2) * (x+3)
(C·D)(x) = 5(x+3) / (x-2)
(C·D)(x) = (5x+15) / (x-2)
Let y(x) = (C·D)(x) = (5x+15) / (x-2)
According to definition of functions, the rational functions are defined for all Real values except the one at which denominator is zero.
It means domain will be all Real values except (x-2)≠0 or x≠2.
Hence, only option B is correct, i.e. all real values of x except x = 2.
Answer: g(x) at (70, 55)
Step-by-step explanation:
The minimum of g(x) is lower than f(x) which is (20, 340) and thats obviously higher than (70, 55) so :)
The answer would be i<span>n step 4, he made an error in determining which value is closer to 82.5</span>
