The answer is c because when you do 5 anything on n you get y
Answer:
Step-by-step explanation:
we know that
If line l is parallel to line m
then
-----> by supplementary angles (consecutive interior angles)
solve for x
Answer:
Sometimes
explanation:
ive already taken this :)
Differentiate both sides of the equation of the circle with respect to
, treating
as a function of
:

This gives the slope of any line tangent to the circle at the point
.
Rewriting the given line in slope-intercept form tells us its slope is

In order for this line to be tangent to the circle, it must intersect the circle at the point
such that

In the equation of the circle, we have

If
, then
, so we omit this case.
If
, then
, as expected. Therefore
is a tangent line to the circle
at the point (1, -2).
Answer:
Option (A)
Step-by-step explanation:
The Barnard's Star is usually considered to be a red dwarf, that is approximately six light-years away from the location of earth. It is present in the Ophiuchus constellation and forms the 4th proximate star to the sun.
Altair refers to the bright shining star present in the Aquila constellation. It forms the 12th brightest star that occurs in the night sky.
Spica is one of the proximate stars to the earth and that is extremely large having a mass of almost ten times the mass of the sun.
The mass of Barnard's star is= 2.864 × 10^29 kg
The mass of the Altair is= 3.56 × 10^30 kg
The mass of the Spica= 19.89 × 10^30 kg
The arrangement of these given stars in the increasing order are as follows-
Barnard's star (minimum) < Altair star < Spica star (maximum)
Hence, the correct answer is option (A).
