Answer:
The approximated value of JK is 10.6 cm answer (A)
Step-by-step explanation:
∵ JI // KH // LG
∵ XI and XJ are two transversal
∴
∵ LK = 18 cm , GH = 22 cm and HI = 13 cm
∴
∴ KJ = (13)(18) ÷ 22 = 10.6363 cm
∴ The approximated value of JK is 10.6 cm
General equation of Ellipse centered at (h,k) is given as
where a is the radius along x-axis
and b is radius along y-axis.
Given : The equation of elliptical path of Earth as
Comparing the equation with the general equation, we get
(h,k) as (-2.5,0)
a =
b =
We have the Sun located at the coordinate (0,0).
Hence, the distance between Sun and Earth in July = 149.5 + 2.5 =152
∴ Earth's distance from the Sun in July is 152 million kilometers.
Answer:
D=-4<0, the equation has no real solutions, it has two imaginary solutions.
Step-by-step explanation:
The quadratic equation has coefficients
a=1,
b=4,
c=5.
The discriminant D is the expression
Hence,
Since the discriminant is negative, the equation has no real solutions, it has two imaginary solutions.
