Answer:
Center and radius of the circle of the equation
center = ( 4,9) Radius = 1
Step-by-step explanation:
Given -
Equation of circle is
The equation of circle is represented by
where a and b are center of circle and radius r
Comparing these equation
then a = 4 and b = 9 and r = 1
(C)
Step-by-step explanation:
We are going to use the following conversions for this problem:
1 km = 1000 m
1 hr = 60 min
The key is to multiply the given quantity with factors such that the unwanted units cancel out, leaving only the ones we need. In this case, we need meters and minutes. The set up goes like this:
Answer:
a1 = 4
a2= -2
a3 = -8
a4= -14
a5= -20
Step-by-step explanation:
a12= a1 + 11d
-62 = 4 + 11d
-62-4 = 11d
-66= 11d
d =
= -6
a1 = 4
a2 = 4 - 6 = -2
a3 = 4 - (6×2) = -8
a4 = 4 - (6×3) = -14
a5 = 4 - (6×4) = -20
