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



Answer:
5.78 * 10^8
Step-by-step explanation:
8.5 * 6.8 = 57.8
5+2=7
In scientific notation the number has to be greater than or equal to 1 and less than ten.
Answer:
y = -
x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2points on the line
m =
= - 
Note the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = -
x + 3 ← equation of line
