Find the 9th term of the geometric sequence 5, -25, 125
Answer:
The previous number keeps getting multiplied by - 5
Step-by-step explanation:
5 × -5 = -25
-25 × -5 = 125
125× -5 = -625
-625 × -5 = 3,125
3125 × -5 = -15,625
-15,625 × -5 = 78,125
78,125 × -5 = -390, 625
-390,625 × -5 = 1,953,125
1,953,125 × -5 = 9,765,625
:)
The 9th term of the geometric sequence is 5⁹.
What is a geometric sequence?A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant. This ratio is known as a common ratio of the geometric sequence.
The formula to find nth term of the geometric sequence is [tex]a_n=ar^{r-1}[/tex]. Where, a = first term of the sequence, r= common ratio and n = number of terms.
The given geometric sequence is 5, 25, 125,..
To find the common ratio, divide the second term by the first term:
r = 25/5
r = 5
The formula for the nth term of a geometric sequence is:
aₙ = a₁ rⁿ⁻¹
Substitute n = 9, r = 5, and a₁ = 5:
a₉ = 5 (5)⁹⁻¹
a₉ = 5 (5)⁸
a₉ = 5⁹
Hence, the 9th term of the geometric sequence is 5⁹.

Which of the following equations would be parallel to the line x = 3?
1. y = 3x
2. y = 1
3. y = x
4. x = 5
Answer:
4. x = 5
Step-by-step explanation:
For two lines to be parallel they must have the same slope, but not be the same line. Both x=3 and x=5 both have slopes of 0, so they are parallel. Another way to tell is that x=3 is a vertical line; therefore, it will be parallel to any other vertical line, such as x=5.

The difference of a number c and 17 is more than 33.
Answer:
c-17=x>33
c=51
Step-by-step explanation:
The value of number c should be greater than 50.
It is given that difference of a number c and 17 is more than 33.
We have to find out the value of number c.
What do you mean by algebraic expressions ?
The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.
As per the question ;
The difference of c and 17 is more than 33.
i.e.,
difference of c and 17 meant ; 17 should be subtracted from c and this is greater than 33.
i.e.,
c - 17 > 33
c > 33 + 17
c > 50
Thus , the value of number c should be greater than 50.

Olivia has five bracelets and three necklaces. She wants to choose one bracelet and one necklace randomly. How many possible outcomes are in this sample space?
Answer:
15 possible outcomes
Step-by-step explanation:
Given: Olivia has five bracelets and three necklaces.
She chooses one bracelet and one necklace randomly.
To find: Number of possible outcomes in a sample space
Solution:
Sample space denotes a set of all possible outcomes.
Number of possible outcomes in a sample space = [tex]\binom{5}{1}\binom{3}{1}[/tex]
Use [tex]\binom{n}{1}=n[/tex]
Therefore,
Number of possible outcomes in a sample space = [tex]\binom{5}{1}\binom{3}{1}[/tex] = [tex]5(3)=15[/tex]

Scott makes and sells bracelets. He spends $28 on supplies, and he sells
each bracelet for $6. Write an expression that represents his profit for
selling b bracelets.
Hi there,
Recall how each bracelet sells for 6 dollars.
Hence, the expression for selling b bracelets is 6b, where b is the number of bracelets sold for the price of 6 dollars.
Profit is the actual amount of money that is earned after you subtract expenses from the total sales.
For instance, if you make $100 from selling items, and you spent $25 on your supplies, then your profit is [tex]100-25=75[/tex].
In this case, you need to subtract the $28 spent on supplies from the amount of money that you have made, which is the expression 6b.
Hence, the expression for the profit is: [tex]6b-28[/tex]
