Any help with the question above??? The graph is attached... ONLY REAL ANSWERS, NO GUESSING!

Answer:
see below
Step-by-step explanation:
The co-vertex is 2 units from center in the x-direction, so the denominator of the x-term will be 2² = 4. Only two answer choices match.
The major axis is parallel to the y-axis, so the foci will have different y-coordinates. Of the two answer choices just found, only one of them has the foci on a vertical line: the choice shown below.
_____
If you actually want to write the equation, note that the center of the ellipse is (-4, -3), and the semi-major axis is 4 units in the y-direction. The standard-form equation will be ...
(x+4)/2² +(y+3)/4² = 1
The distance from center to a focus will be the root of the difference of the denominators, so is √(16-4) = 2√3. That is the distance along the semi-major axis, so puts the foci at (-4, -3±2√3).

After 1 year: $7,256.59
After 5 years: $8,380.52
After 20 years: $14,381.03
APY = 3.66%
Step-by-step explanation:
If you deposit $7000 with an interest of 3.6%, after 1 year using continuous compounding, you will have
After 5 years you will have
After 20 years
To find the APY for the account, we have to compute the interest earned in one year.
We can do it by cross multiplying or by finding a number x such that
Operating on this equation we obtain
x = 0.0366 or 3.66%
