Step-by-step explanation:
2πr is the formula is because the radius of a circle or a face of a circular object is used more often than the diameter. For example, the area of a circle is πr^2.
Answer:
p + 3 = 15
Step-by-step explanation:
15 - 12 = 3
Answer:
C
Step-by-step explanation:
the proof of the answer is seen in the diagram
Answer:
A. (1, 0)
Reason:
When the first equation is graphed: y <u><</u> x + 1, the left side of the line is shaded and when the second equation is graphed: y <u><</u> x^2 -3x, the bottom is shaded.
The green section does not contain solutions. So D is automatically out.
The red section does not contain solutions as well. So C is automatically out.
For choice B, the point goes out of the shaded blue section, so that's out also.
As for choice A its in the blue shaded section, which makes that answer correct.
(when the two equations are within each other and combine a color, then whatever points is within the shaded part is the right answer)
Answer:
20 units
Step-by-step explanation:
Plot points on a graph. doesn't have to be to scale. check co-ordinates differences and add up. see image.
