Option 3: EF, DE, FD is the right answer
Step-by-step explanation:
"The side opposite to the largest angle of a triangle is the largest and the side opposite to the shortest side is the shortest"
We will observe the given triangle according to the axiom stated above
So,
The largest angle in the given triangle is ∠D = 86°, so the side opposite to it, EF will be the largest
Smallest angle is ∠E = 44°, so the side opposite to it, side FD will be the shortest.
Hence,
The sides in order from longest to shortest will be:
EF, DE, FD

Answer:
1.25
Step-by-step explanation:
To get a fraction to a decimal form, you divide the denominator by the numerator. In this case, you'd be dividing 5 by 4
5/4 = 1.25
Answer:
D
Step-by-step explanation:
We are given the equation:
C = (16,000 / r) + (26πr^2 / 3)
<span>First get the 1st derivative:</span>
dC/dr = (-16,000 / r^2) + (52π r / 3)
Equate dC/dr to get the minima:
(-16,000 / r^2) + (52π r / 3) = 0
Multiply everything by r^2:
-16,000 + (52π/3) r^3 = 0
r = 6.65
Therefore the cost at radius = 6.65 is:
C = (16,000 / 6.65) + (26π (6.65)^2 / 3)
C = 3,610.07
So perhaps the interval interest is (0, 3,610.07] if cost or (0, 6.65] if based on radius.
I thin the answer's B, 4/13
