Lets rule some out off the bat, shall we?
The first one you mentioned, a circle is a plane figure with no straight sides... I can name another shape with no straight sides... an oval.
The second one you mentioned, is a true statement
The third one you mentioned, a circle is from a point, not a line segment.
The last one mentioned is also a true statement.
Answer:
Yes.
Step-by-step explanation:
It has only one variable which is only raised to non-negative powers. So, it is a polynomial.
Answer: Hello there!
we have the equation a(n) = (1/2)n - 1 for n ≥ 1
First we need the first five terms:
a(1) = (1/2)*1 - 1 = -1/2
a(2) = (1/2)*2 - 1 = 0
a(3) = (1/2)*3 - 1 = 1/2
a(4) = (1/2)*4 - 1 = 1
a(5) = (1/2)*5 - 1 = 3/2
then we can see that each term is 1/2 bigger than the previous one, then a recursive relation can be written as:
a(n) = a(n-1) + 1/2
where n ≥ 2, and a(1) = -1/2
Y + 2 < 5x.....y < 5x - 2....slope = 5...y int = -2.....less then means shading below the line....dashed line because no equal sign.
y + 3x > 4....y > -3x + 4....slope = -3....y int = 4....greater then means shaded above the line....dashed line because no equal sign
y > = 2x....slope = 2....goes thru the origin (0,0)....greater then means shading above the line....solid line because of the equal sign
