Answer:
an=3*4^(n-1)
Step-by-step explanation:
Geometric Sequence:
r
=
4
Option a: is the solution to the system of equations.
Explanation:
The equations are and
Equating these two equations, we have,
Taking LCM and multiplying both sides by 5, we get,
Simplifying , we get,
Substituting the value of x in , we get,
Thus, the solution is
Changing the solution from fraction to decimal, we get,
Thus, the solution is
Hence, option a is the correct answer.
Answer:
Yes, you are correct because the curve rests on 3 on the x-axis
Answer:
go to m a t h w a y it will help you. but no spaces it would not let me put the hole thing.
Step-by-step explanation:
the general equation of a circle is given by (x-a)^2+(y-b)^2=r^2
where (a,b) are the coordinates of the center.
from the given equation then (1,0) will be the center of the circle. and for the radius of the cirlce equate r^2 with 5...r^2=5 therfore r=
.
