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:

Step-by-step explanation:
1/2 of 1/8 is the same thing as 1/2*1/8.
So multiply it out:
This is the amount of stock that Talia uses.
Now covert:
This is how much Rob owns.
Now add:

Since you cannot simplify, the answer would be
.
Now subtract
from the possible value.
and you get
. This is the portion that they both don't share.
Hope it Helps!
Check the picture below.
recall that a flat-line is always 180°, also recall that all interior angles in a triangle are 180°, therefore
x + 95 + 54 = 180. Surely you'd know what "x" is.
Answer:
0.00375 inches
Step-by-step explanation:
Since the microscope makes the microorganism appear ×200 larger, that would mean we would have to divide by 200 to get the original size. 0.75/200= 0.00375.
Clue: The angle subtended at the centre of a circle is twice that subtended at its arc.
