If you would like to know which is the most reasonable goal for Kirk and his family to plan to save, you can calculate this using the following steps:
a. $225 a month * 2 years * 12 months = 225 * 2 * 12 = $5400
b. $200 a month * 3 years * 12 months = 200 * 3 * 12 = $7200
c. $100 a month * 4 years * 12 months = 100 * 4 * 12 = $4800
d. $75 a month * 5 years * 12 months = 75 * 5 * 12 = $4500
The most reasonable goal to plan to save would be goal b, because $7200 is more than <span>$6845.</span>
The equation of the hyperbola with directrices at x = ±2 and foci at (5, 0) and (−5, 0) is
<h3>How to determine the equation of the hyperbola?</h3>
The given parameters are:
- Directrices at x = ±2
- Foci at (5, 0) and (−5, 0)
The foci of a hyperbola are represented as:
Foci = (k ± c, h)
The center is:
Center = (h,k)
And the directrix is:
Directrix, x = h ± a²/c
By comparison, we have:
k ± c = ±5
h = 0
h ± a²/c = ±2
Substitute h = 0 in h ± a²/c = ±2
0 ± a²/c = ±2
This gives
a²/c = 2
Multiply both sides by c
a² = 2c
k ± c = ±5 means that:
k ± c = 0 ± 5
By comparison, we have:
k = 0 and c = 5
Substitute c = 5 in a² = 2c
a² = 2 * 5
a² = 10
Next, we calculate b using:
b² = c² - a²
This gives
b² = 5² - 10
Evaluate
b² = 15
The hyperbola is represented as:
So, we have:
Evaluate
Hence, the equation of the hyperbola is
