Answer:
Step-by-step explanation:
The equation of a circle with center (h,k) and radius r is given by the formula;
Given (h,k)=(0,0) and r=4, we substitute the values to obtain;
The required equation is
The location of point B after a rotation of point A(-3, 2) 180 degrees about the origin is (3, -2)
<h3>What is a
transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
Rigid transformation is the transformation that does not change the shape or size of a figure. Examples of rigid transformations are <em>translation, reflection and rotation</em>.
The location of point B after a rotation of point A(-3, 2) 180 degrees about the origin is (3, -2)

We know that the 15% of missing pencils is equal to 9
we can use this formula
9/x = 15/100
Then cross multiply
15x = 900
x = 60
There were orignally 60 pencils
The answer is 67.6
You have to find the angle that has cos=8/21=0.381.
