If the center is at (0, 0) and the vertex is at (20, 0), then the distance, a, is the length from the center to the vertex, 20. The distance from the center to the focus is c. The distance from the center to the focus is 16, so c = 16. The formula we use to find the focus is

. We have our c value and our a value, so we will sub in those to find b.

and 256 = 400 - b^2. -b^2 = -144, so b = 12. There you go!
Answer:

Step-by-step explanation:
Answer:
1 quarter pound = 0.25 of a pound.
Give that:
Total amount of ground beef = pound
From 3.5 pound of beef we have to make burgers using 0.25 pound of beef in one burger
We have to find how many burgers can be made:
We have to divide 3.5 pound by 0.25 pound
i.e,
⇒14 quarter pounds burger can be made.
Therefore, 14 quarter pound burgers can George make out of 3 1/2 pounds of ground beef

Step-by-step explanation:
Given that a study of 250 households in Cedar Bluff showed that a household produced an average of 4 pounds of garbage per day.
Here a study of only 250 were made to assess about the entire households in Cedar Bluff
Hence the population of interest in this study is the entire households in Cedar Bluff.
The sample is the 250 households in Cedar Bluff which were studied
The objective was to study the sample and from that information to assess about the population.
