For this problem, we are given the graph of an ellipse, and we need to determine its expression in the standard form.
The standard equation of an ellipse is given below:
Where (h,k) is the center of the ellipse, a is the horizontal radius and b is the vertical radius.
The center of the ellipse on our problem is (-2,2), the vertical radius is 2 and the horizontal radius is 3. We have:
In order to calculate the Foci, we need to first find the eccentricity of the ellipse, which is given by the following formula:
The coordinates of the foci are given by:
The coordinates for the foci are: (-2-sqrt(5), 2) and (-2+sqrt(5), 2).
I’m pretty sure the answer is x^2 + x - 6
.68 because when you set up the problem you just set it up the regular way and put a decimal point and a 0 behind 17 and divide regularly and if its still not even then just add another zero and do the same thing and if its even, that's your answer

Answer:
9 times 800/9 equals 800. (Answer is 800/9)
Step-by-step explanation:
<u>Key skills needed: Equation, Division, Fractions</u>
1) Let's say the number is the variable "x".
2) So this means 9 times x = 800
9x = 800
3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9
