Step-by-step explanation:
Answer:
2 rational numbers i believe
Step-by-step explanation:
Answer:
8% of 1000 is 80
Step-by-step explanation:
<span>x = 24
y = 18
Length of Major Axis = a
Length of Minor Axis = b
Center (0, 0):
h = 0
k = 0
a = 1/2 x
a = 1/2 *(24)
a = 12
b = 1/2 y
b =1/2 (18)
b = 9
So, Equation of Ellipse:
General : (x - h)² / a² + (y - k)² / b² = 1
(x - 0)² / (12)² + (y - 0)² / (9)² = 1
x² / 144 + y² / 81 = 1
Focus = c:
_____
c = √a² - b²
_______
c = √(12)² - (9)²
______
c = √144 - 81 = sqrt63 = 7.9372</span>
Focus : ( -7.9372, 0) and ( 7.9372,
0)
