The equation of an ellipse where the major axis 2a is greater than the minor 2b
(x-h)²/a² + (y-k)²/b² =1.
When 2b>2a , then the equation becomes (y-h)²/b² + (x-k)²/a² =1
In our example a = 4 and b = 9. Moreover h=0 and k=0 because the center is on the origin, so the equation becomes:
y²/b² + x²/a² = y²/81 + x²/16 = 1

Check the picture below

so.. hmm notice the center h,k and the major and minor axis components, thus just plug them in.

Answer:

C - a stack of 15.6 watermelons

Step-by-step explanation:

Lets first go through each option:

"A shopping receipt that totals $4.90":

This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.

"A soccer game where the average score is 4.7":

This is also an appropriate result since it is the average score of a soccer game, so finding a decimal is appropriate.

"A stack of 15.6 watermelons":

This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.

"A classroom with 24 students":

This is an appropriate result since the number of students is a whole number not a decimal.

Hope this helps :)

Answer:

LCM(57624, 416745) = 23,337,720 or LCM = 23337720

Step-by-step explanation:

List all prime factors for each number.

Prime Factorization of 57624 is:

2 x 2 x 2 x 3 x 7 x 7 x 7 x 7 => 23 x 31 x 74

Prime Factorization of 416745 is:

3 x 3 x 3 x 3 x 3 x 5 x 7 x 7 x 7 => 35 x 51 x 73

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 2, 2, 3, 3, 3, 3, 3, 5, 7, 7, 7, 7

Multiply these factors together to find the LCM.

LCM = 2 x 2 x 2 x 3 x 3 x 3 x 3 x 3 x 5 x 7 x 7 x 7 x 7 = 23337720

In exponential form:

LCM = 23 x 35 x 51 x 74 = 23337720

LCM = 23337720

Therefore,

LCM(57624, 416745) = 23,337,720
