Answer:
The distance between foci is 60 feet
Step-by-step explanation:
we are given
a pond has a major axis of 68 feet
so, 
a minor axis of 32 feet
so, 
now, we know ellipse formula

where
c is the distance between center and focus
so, we can plug it and find c


Distance between foci is



You want to solve this set of linear equations by the elimination method.
Let x=price of bag of flour and y=price of bag of sugar
Multiply the first equation by -3.
-3(7x+5y=584)
Multiply the second equation by 5.
5(5x+3y=384)
Solve by elimination.
X=42
Substitute value of x into one of the original equations.
Y=58
Step-by-step explanation:
G(x) = - x^2 + 10x
a + G(a) = a - a^2 + 10a = - a^2 + 11a or 11a - a^2 or a(11 - a)
1/G(a) = 1/(10a - a^2) = 1/a(10 - a)
