Answer:
centre = (13,0)
radius = 8
Step-by-step explanation:
The standard equation of the circle is
(x-x0)^2 + (y-y0)^2 = r^2 ...............(1)
where
(x0,y0) is the centre,
r is the radius.
For
(x-13)^2 + y^2 = 64 ..............(2)
we rewrite (2)
(x-13)^2 + (y-0)^2 = 8^2 ...............(3)
and compare (3) with (1)
to identify
x0 = 13, y0 = 0, and r = 8
Therefore
centre = (13,0)
radius = 8
Answer:
x = 17
Step-by-step explanation:
looks kind of isosceles to me
29 x 2 = 58
180 - 58 = 122
122 + 14 = 136
136 / 8 = 17
x = 17
Answer:
D)
because thats the only answer that would make sence.
Answer:
8.
Step-by-step explanation:
5, 10, 12, 4, 6, 11, 13, 5
Arrange in ascending order:
4, 5, 5, 6, 10, 11, 12, 13.
The median is the mean of the 2 middle numbers:
= (6 + 10) / 2
= 8.
Answer:
x = 40
Step-by-step explanation:
5x + 900 = 1100
=> 5x = 1100 - 900
=> 5x = 200
=> x = 40
Hoped this helped.
