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:620
Step-by-step explanation: lets say the total of school is X so:
X.35÷100=217
when we calculate this the answer will be 620
Answer:
X= 10
Step-by-step explanation:
let the vertex of angle 17° named A
then the other two B and C
then by using trigonometry:
sin(A) = opposite side divided by hypotenuse
opposite side is. X
Wich makes Sin(A) = X/47
then by crossing X= sin(A) × 47 = 13.74147
rounding to the nearest tenth: X= 10
Answer:
6.59999999999999999977 × 10^17
Step-by-step explanation:
6.6 x 10^17 - (9.2 x 10^14)/(4 x 10^16)
We have the following function and point:
The originial function is f (x).
The original function contains the point (-3, -3).
The transformation f (x) - 5 shifts the graph 5 units to the bottom.
Therefore, the new point is:
(-3, -3-5) = (-3, -8)
Answer:
the corresponding point for the function f (x) -5 is:
(-3, -8)
