write an explicit formula for an, the nth term of the sequence 11,2,-7

Answers

Answer 1

Answer:

[tex]a_{n}[/tex] = 20 - 9n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 2 - 11 = - 7 - 2 = - 9

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 11 and d = - 9 , then

[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n

Matt is ordering basketball jerseys For his country's league. Last year he ordered 512 jerseys. 64 those jerseys were orange. If he ordered 600 jerseys this year, how many of them will be Orange if the ratio of orange jerseys to all the jerseys remain the same? Round to the nearest whole number.

Answers

Answer:

75

Step-by-step explanation:

Step 1

Matt is ordering basketball jerseys For his country's league. Last year he ordered 512 jerseys. 64 those jerseys were orange.

The ratio of all Jerseys to Jerseys that are Orange =

512 : 64

8 : 1

Step 2

If he ordered 600 jerseys this year, how many of them will be Orange if the ratio of orange jerseys to all the jerseys remain the same?

Since we are maintaining the ratio in step 1

Let the number of orange jerseys = x

600 : x = 8 : 1

Hence

600/x = 8/1

Cross Multiply

8 × x = 600 × 1

8x = 600

x = 600/8

x = 75

Therefore, this year, the number of orange jerseys = 75

What is the area of the figure, in m2 , shown below?.

Answers

Answer:

The area of this figure is 22 meters squared

Step-by-step explanation:

Two shapes exist on this figure: a rectangle and a triangle. We must first find the area of the rectangle and add that area to the area of the triangle. So first, let's solve the rectangle.

As the area of a rectangle is length multiplied by width, we have 8 * 1 = area, or 8 meters squared. Now we save the value of 8 to add to the area of the triangle. So let's now figure out the area of the triangle.

As the area of a triangle is A = (HB)/(2), or that triangles height multiplied by its base, and dividing that whole number by 2, we can substitute numbers into this equation. This means we take 3.5, the height of the triangle, and multiply that number by 8, the base of the triangle, to get a value of 28. We then divide 28 by 2 to satisfy the equation A = (HB)/(2), and we get the value of 14.

Because of this, we add 8, the area of the rectangle, and 14, the value of the triangle to get a total value of 22. Now let's not forget to add meters squared as the unit of measurement as stated in the question.

This means that the total area of this figure is 22 meters squared.

The area would be 22 meters squared

Jerry borrowed $4000 for 5 years at 6X simple

Answers

Answer:

qqqqqqqqqq

Step-by-step explanation:

Answer:

In this question one has to look forward to the information's already given. Based on those given information's the answer to the question can be easily determined.

Principal amount = $4000

Time for which money is borrowed = 5 years

Rate of interest = 6%

Then

Amount of Interest = Principal * Rate * Time

                              = 4000 * 6% * 5

                              = 4000 * 6/100 * 5

                              = 40 * 30

                              = 1200 dollars

So the amount of interest that needs to be given is 1200 dollars. I hope the naswer and the procedure is clear enough for you to understand.

What is the Slope-Intercept Form of 16x + 4y = 44

Answers

Answer:

Y=-4x+11

Step-by-step explanation:

So first you gotta realize that slope intercept from is

y=mx+b

So you have the equation of

16x+4y=44 as the initial response

Now you just have to isolate it into the from of y=mx+b

SO first subtract 16x on both sides to isolate the 4y since its the initial response as y=mx+b

Then when that is done you should have the answer of

4y= 44-16x

Now You have to isolate the “y”.

By dividing 4 on both sides to get the new equation which will be

y= 11-4x

You can leave it like that or just move around the (x) to make it more plausible as the answer of y=mx+b

y= -4x+11

However you would put it,  that is the answer

y= -4x+11

And

y= 11-4x

What is a function?

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Describe the function between x = - 4 and x = -1.

As the value of x increases the value of the function also increases.

Then the function is an increasing function between -4 to -1.

Between -4 to -1 the function is a linear function.
