Okay, I figured out the first part. Do any of you know number two.
1.If I have the equation (x+4)squared + (y+4)squared = 9
The center of the circle would be (-4,-4) correct?
2. If I have an ellipse with the equation (x-20)squared over 1/4 + (y-10)squared over 1/16 (over is the division sign)
The 1/4 is truly the distance of 1/2 and the 1/16 is truly the distance of 1/4 correct?
Is there an easier way to write this equation?
Thanks.
Do you mean "over 1/4" or "over 4"? If you actually mean "over 1/4" and "over 1/16", the equation is
.
If you meant "over 4" and "over 16", the equation is
which can also be written as
after multiplying both sides by 4(16)= 64.
That sentence doesn't make sense. If you mean "1/4 is the length of the semi-axis parallel to the x-axis and 1/16 is the length of the semi-axis parallel to the y-axis" and you really are talking aboutThe 1/4 is truly the distance of 1/2 and the 1/16 is truly the distance of 1/4 correct?
then the answer is "No". The lengths of the x and y semi-axes are and respectively. If you actually meant
then the answer is stilll "No"- the lengths of the x and y semi axes are and , respectively,
Is there an easier way to write this equation?
Thanks.
