Answer:
Differentiable on the intervals (-∞, -5) ∪ (-5 , 5) ∪ (5 , ∞)
Step-by-step explanation:
The graph will look like a W shape whose vertices are at x = -5 and x = 5. The function is not differentiable at these values.
Answer:
The calculated dollar-weighted rate of return, Y = -25%.
Step-by-step explanation:
The time-weighted rate of return is 0%
Therefore, (12/10)*( X/(12 + X)) = 1
12X = 120 + 10X -> X = 60
The dollar-weighted rate of return,Y is calculated below as:
Y = (X-(10 + X))/(1*10+X/2)
Y = (60-(10+60))/(1*10+60/2)
Y = (60 - 70)/(10+30)
Y= -10/40
Y = -25%
Therefore, the calculated dollar-weighted rate of return, Y = -25%.

Answer:
No
Step-by-step explanation:
The only arithmetic sequence of side lengths that will form a right triangle is (3, 4, 5) or some multiple of that, such as (9, 12, 15).
Sides of length 10, 11, 12 cannot form a right triangle.
