Answer:
Step-by-step explanation:
This is a horizontally stretched ellipse. That means that the horizontal line which is represented by the x-axis is the longer one. The equation for this type of ellipse is

In an ellipse, the a value is ALWAYS bigger than the b value, and since the x-axis represents the longer axis, the a goes under the x-squared term.
To solve for the h, the k, the a, and the b, we simply have to do some counting. The center of the ellipse, the (h, k) our of equation, is sitting at (4, 6). Put them where they belong in the equation. The a axis (the horizontal one) is 8 units long, and the b axis (the vertical one) is 4 units long. Square both of them and put them where they belong in the equation:

There you go!
This is what I got - csc pi/2 - 1 ( on 29 ) and cot pi/4+1 ( on 27 )
I think it's equal to 4, It sounds the most likely
1.5 is the scale factor of a bat wing length to scale drawing length.
The answer to this question is 36. The formula to find area of a square is a squared. By equating that formula to 83 and taking the square root of both sides, we get the value of one side which is 9.1. Then we multiply that value by 4 because all sides of a square have equal values. This our answer becomes 36.4 which is rounded to 36.
