43.96
Explanation:
C=2pi(r)
C=2pi(7)
C=14pi
14 x 3.14 = 43.96

<u>Step-by-step explanation:</u>
The ellipse is vertical so y has the biggest radius.
Major axis (y) = 20 so the y-radius is 20/2 = 10
Minor axis (x) = 14 so the x-radius is 14/2 = 7
The equation of an ellipse is:
where
- (h, k) is the center of the ellipse
- a is the x-radius
- b is the y-radius
Given: a = 7, b = 10
Assume: (h, k) = (0, 0)

Answer:
producers or consumers
Step-by-step explanation:
Given that <span>In a canoe race, team a is traveling 6 miles per hour and is 2 miles ahead of team b.
Team b is also traveling 6 miles per hour. The teams continue
traveling at their current rates for the remainder of the race.
The system of
linear equations that represents this situation is given by
d = 6t + 2
d = 6t
