Answer:
1. B
2.C
Step-by-step explanation:
A plot of land in the shape of a vertical ellipse. The equation of the ellipse is
If the foci are 8 feet from the center, then
If the plot of land is 34 feet across the vertical axis, then
Use formula (because ellipse is vertical, then b>a) to find a:
Then the plot of land is 2a=30 ft across the other axis.
If b>a, the eccentricity of the ellipse is
Answer
not a function
Step-by-step explanation:
Answer:
17%
Step-by-step explanation:
To calculate percent increase use
percent increase = × 100%
increase = 28 - 24 = 4, hence
percent increase = × 100% = 17% ( nearest percent )
