Answer:
The answer to your question is below
Step-by-step explanation:
Data
Equation 25x² + 64y² = 1600
Process
1.- Divide all the equation by 1600
25x²/1600 + 64y²/ 1600 = 1600/1600
-Simplify
x²/64 + y²/ 25 = 1
2.- Equation of a horizontal ellipse

3.- Find a, b and c
a² = 64 a = 8
b² = 25 b = 5
-Calculate c with the Pythagorean theorem
a² = b² + c²
-Solve for c
c² = a² - b²
-Substitution
c² = 8² - 5²
-Simplification
c² = 64 - 25
c² = 39
-Result
c = √13
4.- Find the center
C = (0, 0)
5.- Find the vertices
V1 = (-8, 0) V2 = (8, 0)
6.- Find the foci
F1 = (-√13, 0) F2 = (√13, 0)
Answer: The answer is 16.
Step-by-step explanation:
The least common denominator means the same as least common multiple.
3, 6, 9, 12, 16
8, 16
2, 4, 6, 8, 10, 12, 14, 16
What box plot are you talking about
Step-by-step explanation:
B. -16 + (-7) ...this is the same as -16-7
Answer:
150
Step-by-step explanation:
If you had 3 dollars plus the 10 your mom gave you would have 13. Then, if you dad gave you 30 that would be 43. Plus the 100 your aunt and uncle gave you would be 143. Plus 7 would be your answer of 150
