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:
tan 60 = opp/adj = a/10
a = 10×tan60 = (10 yd)×[(√3/2)/(1/2)]
= 17.3 yd
= 10√3 yd
Answer:
y= 2/3x+3
Step-by-step explanation:
to be parallel they must have the same slope (2/3)
use the ordered pair to get the y-intercept (3)
