Answer:
a_n = 3^(n -1)
Step-by-step explanation:
The n-th term of a geometric sequence with first term a1 and common ratio r is given by ...
a_n = a1·r^(n-1)
Your sequence has first term 1 and ratio r=3, so the sequence is given by ...
a_n = 3^(n -1)

<em>Comment on sequences and series</em>
The sequences we commonly study are "arithmetic" and "geometric." Each of these has an explicit formula for the n-th term, based on the first term and the common difference or ratio. Similarly, each series (sum of terms of a sequence) also has a formula. That's 4 formulas to keep track of; not difficult. One of them, the formula for the n-th term of a geometric sequence, is shown above.

Complete question :
A swimming pool is the shape of a right rectangular prism. If the pool is 12 3/4 yards long, 5 2/3 yards wide, and 9 yards deep, what is the volume of the swimming pool
Answer:
650 1/4 yd³
Step-by-step explanation:
Volume of a rectangle prism :
V = Length * width * height
V = 12 3/4 * 5 2/3 * 9
V = 51/4 * 17/3 * 9/1
V = (51*17*9) / (4*3*1)
V = 7803 / 12
V = 650 3/12
Volume of swimming pool = 650 1/4 yd³
This is easy, first fine your angle theta, so if one point is at (2,-2) , using a polar graph youll know that -2 would be about 315 degrees, the oposite of (2,-2) is (-2,2) which is also (2, 135degrees) your answer is B
im 98% sure this is correct <3
