Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
-5 and 5 make
if you add them you will get 0
-5+5
=0
therefore
<h3>it's b</h3>
Answer:
The answer to your question is
Step-by-step explanation:
Data
F ( 0, ± √14)
C (±√2, 0)
Process
1.- Calculate c
c is the distance from the center to the foci
c = √14
2.- Calculate b
b is the distance from the center to the co-vertices
b = √2
3.- Calculate a using the Pythagorean theorem
a² = b² + c²
a² = (√2)² + (√14)²
a² = 2 + 14
a² = 16
a = 4
4.- We can conclude that it is a vertical ellipse because the foci are in the y- axis and the co-vertices are in the x-axis.
(x - h)²/b² + (y - k)²/a² = 1
-Substitution
(x - 0)²/(√2)² + (y - 0)²/4² = 1
- Simplification
x²/2 + y²/16 = 1
or
By plugging s and t in for each equation you should get
22. 9
23. 16/15625
24. -81/49
( I'm not 100% sure about 23 but i am about the other 2)
To multiply you have to distribute. 3(h-5) will be 3h-3(5) which is 3h-15. So the answer is 3h-15
See how many times the denominator goes into the numerator. For example, with 24/8, 8 goes into 24 three times, so 24/8 is 3. If I had 25/8, then it would be 3 1/8 because you have one left over after you divide the 8 into 25.
