Sequences and series

Answer: D) Geometric; r = 4

===========================================================

Explanation:

The sequence is not arithmetic because the distance between adjacent terms keeps increasing. For instance, the gap from 0.4 to 1.6 is 1.6-0.4 = 1.2, while the gap from 1.6 to 6.4 is 6.4-1.6 = 4.8. There is no common difference, so we can rule out choices A and B.

To check if we have a geometric sequence, divide each term by its previous term

(term2)/(term1) = (1.6)/(0.4) = 4

(term3)/(term2) = (6.4)/(1.6) = 4

(term4)/(term3) = (25.6)/(6.4) = 4

Each time we get 4 as a result, so this sequence is geometric and the common ratio is r = 4.

Put another way: each new term is found by multiplying the previous term by 4.

0.4*4 = 1.6

1.6*4 = 6.4

6.4*4 = 25.6

This all leads to D being the answer.

Side note: the nth term of this geometric sequence is [tex]a_n = 0.4*(4)^{n-1}[/tex] where n is a positive integer and starts at n = 1.

carrie and joel plan to sell apple pies at the county fair for $6 each. the ingredients they used cost $3.75 per pie. they rent an oven for $54 to keep the pies hot throughout the day. how many pies must carrie and joel sell in order to break even?

Answers

Answer:

24 pies

Step-by-step explanation:

Let x represent the number of pies and set up an equation:

6x = 3.75x + 54

Solve for x:

6x = 3.75x + 54

2.25x = 54

x = 24

So, Carrie and Joel have to sell 24 pies to break even

no

Step-by-step explanation:

Reason: if we solve for this we end up with the x values equaling to zero. This leaves us with 4 = - 4. This is not true because 4 isn’t equal to -4. If they were equal they would be the same value.

which of the following is the slope intercept form of the equation of this line

Answers

Answer:

The slope-intercept form of the equation of this line is:

[tex]y=-x[/tex]

Hence, option 'c' is true.

Step-by-step explanation:

From the line equation, let us take two points

(1, -1)(-1, 1)

Finding the slope between two points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-1,\:1\right)[/tex]

[tex]m=\frac{1-\left(-1\right)}{-1-1}[/tex]

[tex]m=-1[/tex]

From the line graph, we can determine the y-intercept by setting x=0 and checking the y-value at x=0

at x=0, y=0

Thus, (0, 0) is the y-intercept

We know that the slope-intercept form of the line equation is

y=mx+b

where

m=slope b=y-intercept

As we have already determined m=-1 and y-intercept=b=0

so substituting m=-1, b=0 in the slope-intercept form of the line equation

[tex]y=mx+b[/tex]

[tex]y=(-1)x+0[/tex]

[tex]y=-x[/tex]

Thus, the slope-intercept form of the equation of this line is:

[tex]y=-x[/tex]

Hence, option 'c' is true.

Determine if the point (5, 7) is on the line of
Equation 5x + 6y = 67

Answers

Answer: The point (5,7) is on the line 5x+6y = 67

=====================================================

Explanation:

(5,7) means x = 5 and y = 7 pair up

Plug in those values to get...

5x + 6y = 67

5*5 + 6*7 = 67

25 + 42 = 67

67 = 67

We get the same number on both sides after fully simplifying. This means the equation is true. A true equation in the last step means the first equation is true when (x,y) = (5,7).

Therefore, the point (5,7) is a solution and it is on the line 5x+6y = 67.

4 3/8-(-5 7/8)=

Answers

Answer:

10 1/4

Step-by-step explanation:

okay so the equation 4 3/8-(-5 7/8) needs to be simplified to a answerable equation by changing -(-5 7/8) to + 5 7/8

the reason for this is because when two subtraction signs are like this -(- it turns the number into a positive and we add instead of subtract.

4 3/8 + 5 7/8 = 9 10/8 = 10 2/8 = 10 1/4

One can say that no turban-wearing male minister would have been capable of dealing with these matters as brilliantly as she did. Her husband used to consult her first on any state business, be it military or political, and would always take the course she recommended. After her husbands death, she took control of her sons with great wisdom. Even though each one of them was prince and therefore capable of ruling by his own will, she made sure they never departed from the rules of the ancient Mongol laws of conduct. When her son, Gyk Khan, was raised to the throne, he and his brothers were the only princes who because of Bekis wise guidancewere found always to have acted according to the laws. The great nobles of the assembly that gave the khanate to Gyk are said to have praised Beki with the following verse: And if all women were like her, then women would indeed be superior to men. Although she herself was a Christian, Beki generously supported the Muslim religion. She gave 1,000 silver coins to build an Islamic school in the city of Bukhara. She also gave alms every year to be distributed among the poor and needy Muslims.

Group of answer choicesIn part because of Mongol societys nomadic nature, elite Mongol women exercised considerably more political power and influence than did women in most other contemporary societies.Because of the highly militarized structure of Mongol society, Mongol women could use their fighting skills to negotiate a more powerful position in society than could women elsewhere.The Mongol custom of having an assembly of male notables as the final decision-making body left Mongol women mostly powerless, in contrast to the situation in most other Eurasian societies.Because Mongol society had no distinctions based on birth or nobility, all Mongol women, regardless of their position in society, were expected to behave in the same way. how do you think the world is gonna look in the future?
