Answer:
Step-by-step explanation:
Given
Fireplace is in the form of semi-ellipse with height of 3 ft from center
Length of base=8 ft
if the arch is in the form of ellipse then it can be considered as horizontal ellipse with 2 a and 2 b be length of major and minor axis
2 a =8
a=4 ft
If contractor cover the whole base
then total length of string=2a =8 ft
(b)String should be nailed at focus
focus of ellipse is a e
where e=eccentricity
Focus
Thus string should be nailed at 2.64 m from center
Answer:
The answer to your question is k =
Step-by-step explanation:
Equation
5 - vk = k
Process
1.- Add vk in both sides
5 - vk + vk = k + vk
2.- Simplification
5 = k + vk
3.- Factor k (like terms)
5 = k(1 + v)
4.- Divide both sides by "1 + v"
5 / (1 + v) = k(1 + v) / (1 + v)
5.- Simplify
5 / (1 + v) = K
