Answer:
Function with smallest zero is:
f(x); (2, 0).
Step-by-step explanation:
f(x):
2x2 − 14x + 20 = 0
x^2 - 7x + 10 = 0
(x - 5)(x - 2) = 0
So the zeroes are (2, 0) and (5, 0)
g(x):
From the table:
when g(x) = 0, x =19 so its zero is (19, 0).
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
R=2K which equals 2R=4K
4(R=K+8) or 4R=4K+32
Subtract first equation from second equation.
2R=32 so R=16
Plug into first equation
16=2K so K=8
Now plug both into second equation to check
4R-4K=4(R-K)=4(8)=32 it works
So Roberto is 16 and Katie is 8
(In 4 years R would be 20 and K would be 12 which has a difference of 8)
