Let
be the n'th term of the sequence.
so
is the first term,
the second term and so on...
In a geometric sequence with
, and common ratio r, the terms are as follows:
.
.
that is, each term is its previous term times the common ratio r.
In our example
and
so
Answer: r=0.75
Answer:
The negative solution
-2
Step-by-step explanation:
Let the number be
Then 5 times the number is 5x.
14 less than the square of the number is
So our equation becomes
This implies that
We factor to get:
Answer: 106.76yards
Step-by-step explanation:
Circumference of a circle is given as:
= 2πr
where,
π = 3.14
r = 17 yards
Circumference = 2πr
= 2 × 3.14 × 17.
= 106.76yards
Therefore, the circumference of the circle will be 106.76yards
Answer: -1+6y+7x
To simplify expressions, you have to be able to combine like terms (eg. 3x and 2x to get 5x). Since there are none in this expression, and you can't combine y and x, this expression can't be simplified.
*If it helps, think of x and y as different types of candy... ;3
For example, you can't combine 12 Skittles (x) and 4 Reese's (y), because they aren't the same. So, you'd write that you have 12 Skittles and 4 Reese's.
