A disjunction is false if both parts of the disjunction are false; otherwise, it is true
----------------------------------------------
Choice A
4-3=2 is false
6*3=9 is false
both parts are false, so overall the entire disjunction is false
----------------------------------------------
Choice B
5*6=30 is true
3+4=7 is true
Neither part is false, so overall the entire thing is true
----------------------------------------------
Choice C
8+3=11 is true
5*4=23 is false
While second piece is false, the overall disjunction is true. The first part (true) makes the whole thing true.
----------------------------------------------
Choice D
7+6=13 is true
5*2=10 is true
Neither part is false, so overall the entire thing is true
----------------------------------------------
----------------------------------------------
In summary, we have
A. False
B. True
C. True
D. True
Making choice A the only answer that is false. So choice A is the final answer
Answer:
The minimum average cost per dulcimer is 150 and the minimum cost is $180.
Step-by-step explanation:
The given cost function is
Differentiate the function C(x) with respect to x.
Equate C'(x)=0, to find the critical values.
Divide both sides by 0.4.
Differentiate the function C'(x) with respect to x.
At x=1.5
The value of double derivative is positive. It means the function is minimum at x=1.5 hundred.
1.5 hundred = 150
Substitute x=1.5 in the given function to find the minimum average cost.
The minimum cost is 1.8 hundred dollars.
1.8 hundred dollars = $180
Therefore, the minimum average cost per dulcimer is 150 and the minimum cost is $180.
I’m pretty sure the answer is (-2,-1)
