Answer: The answer is leg(s).
Step-by-step explanation: In a triangle you have two parts, a hypotenuse and 2 legs. The legs are adjacent, or opposite, to the right angle. The hypotenuse is actually the right angle itself.
For the table, we can count the circles that appear in each step of the fractal. The center is a single circle and is step 0. Step 1 sees 4 circles grow off of that one circle. Step 2 sees 4 circles grow off of each of these circles. Therefore the table should be:
Step 0 : 1 circle
Step 1 : 4 circles
Step 2 : 16 circles
Step 3: 64 circles
Using this table, we can solve the second part. This function is exponential growth and each step is a multiple of 4. Therefore, the function is

.
For this case we must find a fraction such that its result is given by a decimal of the form:
, that is, a repeated decimal.

Option D
Answer:
135
Step-by-step explanation: Multiply 160 by 0.85(for 85%) and you get 135
Hi,
Part A:

Part B;
Vertex is (3,7)
As the coefficient of n² is positive , the vertex is a minimum.
Part C:
Axis of symmetry is n=3
