Write the equation of an ellipse with a major axis of length 8 and co-vertices (0,3) and (0,-3)
alexandr1967 [171]
If the co-vertices are (0, 3) and (0, -3) where x is 0 and y has a value, then y is the minor axis.  That means that the x axis is the major axis.  Because of what the co-vertices are, the center of the ellipse is at the origin.  The formula for an ellipse that has a horizontal major axis is \frac{(x-h)^2}{a^2}+ \frac{(y-k)^2}{b^2}=1.  The a value will always be larger than the b value, therefore, the a value goes under the coordinate that is the major axis.  Here, its the x-axis.  a is the distance that the outer edge of the ellipse is from the center.  It's 8 units away from the center along the x axis and 3 units along the y axis from the center.  So a = 8 and a^2 = 64; b = 3 and b^2 = 9.  Our formula then is \frac{x^2}{64}+ \frac{y^2}{9}=1

What is lim x→-3 sqrt x^2-8
vitfil [10]

If the  -8 is under the square root, then...

\displaystyle L = \lim_{x\to -3} \sqrt{x^2-8}\\\\L = \sqrt{(-3)^2-8}\\\\L = \sqrt{9-8}\\\\L = \sqrt{1}\\\\L = 1\\\\

OR

If the -8 is not under the square root, then...

\displaystyle L = \lim_{x\to -3} \sqrt{x^2}-8\\\\L = \sqrt{(-3)^2}-8\\\\L = \sqrt{9}-8\\\\L = 3-8\\\\L = -5

Either way, we replace x with -3 and simplify.

For more information, refer to the direct substitution rule for limits.

Which of the following diagrams represents 80%?<br><br>Help please. it'd be very appreciated. :)​
Alenkasestr [34]

Answer:

H

Step-by-step explanation:

there is 10 parts to the shape so your denominator would be 10 then if you count the shaded area there's 8, so 8 would be your numerator

8/10 = 0.8 or 80%
