Distance formula ds = v(dx² + dy²) s = ? v(1 + (dy/dx)²) dx ......... s = the arc length y = 171 - x²/45

Answer: We should add the constant 81 to the expression to have a perfect square trinomial.
The perfect square trinomial that would be formed would result from (x + 9)^2.
We can use foil to prove it.
(x + 9)(x + 9)
x^2 + 9x + 9x + 81
x^2 + 18x + 81
81 is the value that must go with 18x in the middle to form the perfect square trinomial.
Answer:
160°
Step-by-step explanation:
The formula below gives the measure of an interior angle of a regular polygon of n sides.
[(n - 2)180]/n
[(18 - 2)180]/18
16(10)
160
Answer: 160°
6x/6=x>/= (=) 11/6
x=11/6 or about 1.8
the first important notation to remember when graphing inequalities is that the graph is going to face the way the inequality sign is pointing.
in this case, the sign is pointing right. now the second thing to remember is that an inequality sign with a line underneath it means that it is greater/equal to so the graph in which we fill will have be a closed circle
1) start the ray at ~1.8 and fill in the circle at the end of the ray then extend to its endpoint
that's all. you're graph now reads x is greater or equal to 11/6
