Answer: Choice B
Equation of a circle with (0,0) as its center and radius = 1
---------------------------------------------------------------
Explanation:
Recall that the unit circle is the equation
x^2 + y^2 = 1
This is a circle with center (h,k) = (0,0) and radius r = 1
It is in the form
(x-h)^2 + (y-k)^2 = r^2
We can write the first equation mentioned in the form sin^2(t)+cos^2(t) = 1
Using
x = cos(t)
y = sin(t)
t = angle
The point P(x,y) on the unit circle has an x coordinate of cos(t) and a y coordinate of sin(t). We can see this through drawing a right triangle.
Marcy
The school and Marcy are on the same x axis on the grid at -3 whilst Henry is the opposite end of the axis. Thus on the x axis Marcy is closer
On the y axis Henry is closer as they are both on 8 and Marcy is on 2
However overall Marcy is closer as the difference between -3 and 4 is 7 and the difference between 2 and 8 is 6
Hope this is right And hope it helps!

<span>In this case, every bottle has 500 mg of caffeine with a standard deviation of 25 mg. The equation of a bottle will be: 500 +/- 25mg caffeine per bottle.
To calculate a carton containing 30 bottles, you just need the equation with 30. It will become: (500x30) +/- (25x30)mg= 15000 +/- 750 mg of caffeine per carton</span>
