Sum of the First n Terms of a Geometric Sequence
Given a geometric sequence (or series) with a first-term a1 and common ratio r, the sum of the first n terms is given by:
We are given the series:
Before calculating the required sum, we need to find the common ratio. It's defined as the division of two consecutive terms. For example, using the first two terms:
The first term is a1 =120. Now apply the formula:
Operating:
Calculating:
Alright, lets get started.
For making complete square, we will add and subtract 49 in this
Comparing the standard equation of parabola
where (h,k) are vertex
So, comparing the equation with standard one, h, k would be = (-7 , -89)
So, the vertex are (-7 , -89) : Answer
Hope it will help :)
Answer:
27
Step-by-step explanation:
The area of this parallelogram is its base times height. 6x4.5 is 27.
Hope this helps! (please mark me brainliest)
I think the answer is 46.
