Answer:
r = - [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The n th term of a GP is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 18 and a₆ = - [tex]\frac{2}{27}[/tex] , then
18 [tex]r^{5}[/tex] = - [tex]\frac{2}{27}[/tex] ( divide both sides by 18 )
[tex]r^{5}[/tex] = - [tex]\frac{1}{243}[/tex] ( take the fifth root of both sides )
r = [tex]\sqrt[5]{-\frac{1}{243} }[/tex] = - [tex]\frac{1}{3}[/tex]

solving slope with work tho please
Answer:
First is 5/2
second is 1
Answer:
1. A. slope = 5/2
2. A. slope = 1
Step-by-step explanation:
To find the slope you can input the x and y values of two points into this expression: [tex]\frac{y2 -y1}{x2 - x1}[/tex]
1. To find the slope, I'm going to use points (2, 3) and (4, 8). Let's input them into the expression:
[tex]\frac{8-3}{4-2}[/tex]
Simplify:
8 - 3 = 5
4 - 2 = 2
The slope is 5/2.
2. To find the slope, I'm going to use points (0, 0) and (1, 1). Let's input them into the expression:
[tex]\frac{1-0}{1-0}[/tex]
Simplify:
1 - 0 = 1
1 - 0 = 1
The slope is 1/1, or just 1.

what was the significancHeather has an international cell phone plan.
The number of texts she sent in September can be represented by x.
She pays $30 per month plus $0.05 per text.
Her bill for September was $60.
What is x, the number of texts Heather sent during the month of September?
Answer: x = 500
Step-by-step explanation:
1. You turn it into 30 + 0.05x = 60
2. Subtract 30 from both sides to get 0.05x = 30
3. Then divide 30 by 0.05 and get 600
4. Write down x = 600

What is the slope of a line perpendicular?
y=-3/4x +3
Answer:
4/3 equation however is y = 4/3x + 3 (the plus three can be changed to anything
Step-by-step explanation:
Lemme just tell you this:
If you are looking for the equation of a completely perpendicular line,
just find the COMPLETE OPPOSITE of the current slope. -3/4x would be 4/3 because it is the opposite in terms of positive or negativeness and the way the numbers are arranged. Change the sign, flip the number, and you are good to go.

The table and graph both represent the same relationship.
Which equation also represents that relationship?
Answer:
x = 1
Step-by-step explanation:
From the table shown in the picture,
For input value x = 1, output values of y = 2, 4, 6, 8, 10
Similarly, from the graph shown,
For input value x = 1, output values of y = 2, 4, 6, 8, 10
Therefore, both will represent the same relationship.
From the graph attached, straight line parallel to y-axis is x = 1.
Therefore, x = 1 will be the correct option.

a distributor wants to make 1000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?
Answer:
200 pounds 20% raisins
800 pounds 5% raisins
Step-by-step explanation:
Let number of 5% be x
and number of 20% be y
x + y = 1000
Also;
5% of x + 20-% of y = 8% of 1000 pounds
= 0.05x + 0.2y = 80
From i , x = 1000-y
0.05(1000-y) + 0.2y = 80
50-0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
= 1000-200 = 800
He will use 800 pounds for a mix that is 5% raisins and 200 pounds for a mix that is 20% raisins.
Given that,
A distributor wants to make 1000 pounds of trail mix that is 8% raisins.
He will use a mix that is 5% raisins and a mix that is 20% raisins.
We have to determine,
How many pounds of each should he use.
According to the question,
Let number of 5% raisins be x,
And number of 20% raisins be y.
Then,
He will use a mix that is 5% raisins + A mix that is 20% raisins = Distributor trail mix.
[tex]x + y = 1000[/tex]
And,
He will use a mix that is 5% raisins of x + and a mix that is 20% raisins of y = 1000 pounds of trail mix that is 8% raisins.
5% of x + 20% of y = 1000 of 8% raisins
[tex]0.05 x+ 0.20y = 80[/tex]
On solving both the equation,
[tex]x + y =1000\\\\x = 1000-y[/tex]
Substitute the value of x in the equation 2,
[tex]0.05 (1000-y) + 0.20y = 80\\\\0.05 \times 1000 - 0.05y + 0.20y = 80\\\\50 + 0.15y = 80\\\\0.15y = 80-50 \\\\0.15y = 30\\\\y = \dfrac{30}{0.15}\\\\y = 200[/tex]
Substitute the value of y in the equation 1,
[tex]x + y = 1000\\\\x + 200 = 1000\\\\x = 1000-200\\\\x = 800[/tex]
He will use x = 800 pounds a mix that is 5% raisins and y = 200 pounds for a mix that is 20% raisins.
Hence, He will use 800 pounds for a mix that is 5% raisins and 200 pounds for a mix that is 20% raisins.

A company that teaches self-improvement seminars is holding one of its seminars in Belmont. The company pays a flat fee of $250 to rent a facility in which to hold each session. Additionally, for every attendee who registers, the company must spend $4 to purchase books and supplies. Each attendee will pay $14 for the seminar. Once a certain number of attendee register, the company will be breaking even. How many attendees will that take?
Answer:
Step-by-step explanation:
250 for place 4 for books each.
If they charge 14 per person, 4 of that goes for the books and 10 will be applied to the rental fee.
250/10= 25 people to break even. Any people beyond that is a profit of 10.00 since the other 4 will still go to the books.
