This is an equation representing the ellipse
Explanation:
- The general equation for an ellipse is
so, when you simplify it according to the characteristics of a and b, you would end up in the similar form of the equation given
- where a represents half the length of the major axis and b represents half the length of the minor axis.
- The easiest method to identify, look at whether both the variables are squared, and also the coefficient of x and y should be positive but different.
The answer would be -17/15 or -1 2/15
Answer:
A
Step-by-step explanation:
Since the angle that is touching each other shows that it is equal, the lines also show equality. So the number of lines in one of them is the same length in the other.

Answer:
40,320.
Step-by-step explanation:
We are asked to find the number of ways in which 8 books could be arranged on a shelf.
The 1st could be arranged in 8 ways. Since one place is filled, so 2nd book could be arranged in 7 ways.
Similarly, the 3rd book could be arranged in 6 ways as first two places are already taken. This process will go on.
So the 8 books can be arranged in 
Therefore, 8 books could be arranged in 40,320 ways.
