Answer:
The geometric sequence is
36,24,16,
,.......
Step-by-step explanation:
The first term of the g.s is 36.
The 4th term of the given sequence is
.
The
term of the geometric sequence is

Where a is the first term of the geometric sequence and r is the geometric sequence.
Then 4th term of the sequence is



![\Rightarrow r=\sqrt[3]{ \frac{8}{27}}](https://tex.z-dn.net/?f=%5CRightarrow%20r%3D%5Csqrt%5B3%5D%7B%20%5Cfrac%7B8%7D%7B27%7D%7D)

Then, second term of the sequence 

=24
The third term of the sequence is

=16
The geometric sequence is
36,24,16,
,.......
Answer:

Step-by-step explanation:
The standard form of an equation of a circle:

(h, k) - center
r - radius
We have the center (-5, 0) and the radius r = 8. Substitute:

Answer:
-5y=-10x+100
y=2x-20
6y=-3x-7
y=-1/2x-7/6
Perpendicular because the slopes are opposite
Answer:
The number of packages Justin needs to buy to get x cards is x divided by 3.
- <u>Rule as an algebraic expresssion:</u>

Explanation:
This is a direct variation problem.
Since each package has the same number of cards, the number of cards is proportional to the number of packages.
12 baseball cards in 4 packages means that there are 12/4 = 3 cards per package, so:
- The number of cards is 3 times the number of packages.
- The number of packages is the number of cards divided by the number of 3.
So, the <em>rule in words</em> for the number of packages Justin needs to buy x cards is one third of x. This table may help you to visualize it:
Number of packages: 1 2 3 4 5
Number of cards: 3 6 9 12 15
To find the <em>algebraic expression</em> that describes the same rule, you can set the following proportion:

Where y is the number of packages and x is the number of cards.
And from that you solve for y:

answer is 4 because negative symbols are going to be positive.
