Answer:
12750
Step-by-step explanation:
The sequence of visitors is
50, 100, 200, 400, .....
This is a geometric sequence
with common ratio r = 2
The sum to n terms is found using
=
( a is the first term )
=
= 50 × 255 = 12750

Check the picture below.
the triangle is an isosceles, so it has twin legs, and a base bottom.
the twin sides stem from the "vertex", and we know the vertex is 120°, and since the triangle is inscribed in a circle, because the circle is "circumscribing" it, then the base side of the triangle will be the diameter of it.
if we run a perpendicular line to the base from the vertex, we'll split the vertex in two 60° angles, as you see there, giving us a 30-60-90 triangle on each side.
so, anyhow, the rest is just a matter of using the 30-60-90 rule.
that's the diameter, and as you know, the radius is just the length of the base, or half the diameter.

Answer:
The function rule is
Step-by-step explanation:
The given ordered pairs are (0,-1), (1,0),(2,3),(3,8),(4,15)
We can observe the following pattern.
When we generalize this pattern, we obtain:
This is the function equation.
The function rule is
