<span>Graphs can be used to represent periodic data because you can show rise and fall of something and express situations that may be tough to show in writing.</span><span>
In the case that the periodic data is on the range of the function (the y axis)
You can use functions to represent periodic data:
example y=sin(x)</span>
Answer:
B
Step-by-step explanation:
The equation of a circle is
(x-h)^2 + (y-k)^2 = r^2
h= 9, k = -7
r = 2, so r^2 = 4.
We now know that the equation must equal 4, so we can rule out answers A and C.
Plug in the values for h and k to get
(x-9)^2 + (y+7)^2 = 4
Choice B is correct!
Its A!
if you plug 4 and -7, the equation works
Step 1 is, "draw arcs through both legs of the angle, centered at the vertex of the angle."
_____
The arcs crossing the two legs have the same radius. One arc crossing both legs can be used, if you like.
You would have to divide 37.2 by 10. The answer would be 3.72.
