Answer:
Step-by-step explanation:
An ellipse is the locus of a point such that its distances from two fixed points, called foci, have a sum that is equal to a positive constant.
The equation of an ellipse with a center at the origin and the x axis as the minor axis is given by:
Since the distance of the satellite from the surface of the moon varies from 357 km to 710 km, hence:
b = 357 km + 959 km = 1316 km
a = 710 km + 959 km = 1669 km
Therefore the equation of the ellipse is:
Answer:
It is a GP.
Step-by-step explanation:
a = 3
r = 2
a(n) term = ar^n
As it increases as multiples, it is a geometric progression or a GP.
I think it’s D, hope that helps
If, "F" = 'ma'.
then↓
4.5(9) = 40.5
So, that means 40.5 is the answer for this question

Answer:
B. -x^2 + 3x + 7
Step-by-step explanation:
(f -g)(x) = f(x) -g(x) = (3x +1) - (x^2 -6) . . . . substitute the functions
= 3x +1 -x^2 +6 . . . . . . . eliminate parentheses; next, collect terms
= -x^2 +3x +7 . . . . . matches choice B
