What is the common difference for the arithmetic sequence: 8.6, 6.2, 3.8, 1.4, −1, −3.4, …

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

If you start with t1 = 8.6

and t2 = 6.4

Then tn - tn-1 = 6.4 - 8.6 = -2.4

In other words if you start at tn-1 and go to the next term tn you have to subtract 2.4 from the term to get to the next term.

t1 = 8.6

t2 = 6.2

t2 = 8.6 - 2.4 = 6.2

The difference is -2.4

In general tn+1 = tn - 2.4

Answer 2
Answer:

Answer:

So the common difference is -2.4

Step-by-step explanation:

In an arithmetic sequence the common difference is the difference between any two consecutive terms

also formula for common difference is d= a(n) - a(n-1)

which means that if we have an arithmetic sequence i.e. a1,a2,a3 and a4

then their common difference will be

common difference = a₂-a₁= a₃-a₂ = a₄ -a₃

Now for the given sequence

Common difference = 6.2 - 8.6

                                  = - 2.4

Check:

8.6 - 2.4 = 6.2

6.2 - 2.4 = 3.8

3.8 - 2.4 = 1.4

.

.

So the common difference is -2.4

a) Determine an equation for the population with respect to the number of years after 2014, assuming that the population increases at a constant rate.

Solution

The function will be of the form

p=a r n, where a is the initial population, r is the rate of increase, n is the time in years and

p is the population.

p=584,513(1.0002)n

This will be the vertex of the function. We will need to complete the square.P=−54x2+15x+200

P=-54(x2−12x)+200

P=−54(x2−12x+36−36)+200

P=−54(x−6)2+45+200

P=−54(x−6)

The optimum price is $6 per bag.

Final answer:

Graphed functions solve real-world problems by visualizing data for economic modeling, demonstrating relationships, trends, and comparisons. Second, they display statistical data, aiding in understanding proportions and comparisons.

Explanation:

The graphed function could be used to solve real-world problems in two major ways. First, graphs like line graphs, pie charts, and bar graphs can be used in economic modeling to visualize data, illustrating patterns, comparisons, trends, and allocation.

For example, a line graph can demonstrate the relationship between two variables such as a company's sales and its advertising budget over time, helping to inform marketing strategies.

Secondly, graphs also play a crucial role in displaying statistical data. For instance, a bar graph could be used to compare the population size of different countries, while a pie graph could visually represent the percentage of a total budget allotted to different departments within a company.

Which equation represents a circle with a center at (2, –8) and a radius of 11?

Answers

(x-h)^2 +(y-k)^2 = r^2 is the equation for a circle centered at (h,k) and radius r

(x-2)^2 +(y- (-8))^2 = 11^2

(x-2)^2 +(y+8)^2 = 11^2

Answer:(x-2)^2 +(y+8)^2 = 11^2

Answer:

(x-2)^2 + (y+8)^2 = 11^2

Step-by-step explanation:

The standard equation of a circle with center at (h,k) and radius r is

(x-h)^2 + (y-k)^2 = r^2.

Filling in the given info, we get:  

(x-2)^2 + (y+8)^2 = 11^2
