<u>Answer:</u>

Initial value: 250
Decay
Decay rate: 11%

Initial value: 40
Growth
Growth rate: 11%
<u>Step-by-step explanation:</u>
The function we have on the left of the table is:

<u>Initial value</u> (when x = 0): 
y = 250 (initial value)
Growth or Decay: 0.89 < 1 so decay
Decay rate: (1 - 0.89) * 100 = 11%
Function on right side:

<u>Initial value</u> (when x = 0): 
y = 40 (initial value)
Growth or decay: 1.11 > 1 so growth
Growth rate: (1.11 - 1) * 100 = 11%
To solve this, you first subtract 60 by 18 to get 42
You then divide this by 2 to get 21
So, it'll take 21 minutes
Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.
