Answer:
36 pieces of ribbon
Step-by-step explanation:
When Audrey cuts the ribbon into pieces that are each 1/3 yards long, she has 18 pieces (1/3 * 18 is 6, or the other way to think about it would be, 6 / (1/3) = 18). If she were to cut each of the pieces in half one more time, she would have 18 * 2 or 36 pieces of ribbon
Answer:
1. C points radially outward from origin
2. A. Points radially outward from z origin
3. D. Radially inwards toward origin
4. B. Inwards towards the z axis
Step-by-step explanation:
1.
X²+y²+z² = f(x,y,z)
Vector P<x,y,z>
2<x,y,z> = 2p
The answer is c points radially outward from origin
2.
X²+y² = f(x,y)
<2x,2y,0>
Points radially outward from z axis
3.
D. Points radially inwards toward origin
4.
B. Points radially inwards toward the z axis.

The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^2, wherein the center of the circle is at (h,k) and its radius is r. In this case, the circle has the center at (5, -3) with a radius of 5. Thus, the point (0,-3) is on the circle since this point is exactly 5 units to the left of the center of the circle which is equal to the radius of the circle.
