Answer:
Step-by-step explanation:
<u>Formula is given</u>
<u>If C = 15 yd, π = 3.14, then r is</u>
- C = 2πr
- r = C/2π
- r = 15/(2*3.14) = 2.39 yd rounded to the nearest 100th
Answer:
3x - y = -7
Step-by-step explanation:
put into slope-intercept form the equation becomes <em>y = 3x + 7</em>
parallel lines have the same slope, in this case the slope is 3
Answer: p = 42
The bottom chord is 21+21 = 42 units long. This bottom chord is 11.2 units away from the center. Any other chord the same distance from the center will have the same length. The top chord has the same length of 42 units as it is also 11.2 units from the center.
The <u>correct answer</u> is:
B) Statement 1 and Statement 2 are theorems because they can be proved with the help of appropriate postulates.
Explanation:
<u>Statement 1</u> is the Line Intersection Theorem. To prove this, we use postulates about having only one plane passing through any 3 noncollinear points. We would choose two points from one line and one point from the second; they would be non-collinear points and be in one plane. This also works choosing the points the opposite way.
<u>Statement 2</u> is the Point and Line Contained in Plane Theorem. Again, if two lines intersect, we can choose three points to define
a plane. We have to prove that both lines are in the plane. We rely on previously proven postulates to do this.
