Answer:
60%
Step-by-step explanation:
18 divided by 30 is 0.6, and then just move the decimal two to the right and you have 60.
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.
Answer:
11 must be squared.
Step-by-step explanation:
X+9=27
X=27-9
X=18

Since y=y. set the equations equal to each then solve
2x + 1 = -x + 4
+x +x
3x + 1 = 4
-1 -1
3x = 3
/3 /3
x = 1
