How do you write a recursive formula

Answers

You need to show how a term of formula is based on a previous term.

For example, let's say you have the sequence 3, 6, 9, 12, ...
(multiples of 3).

As a regular function, you can have y = 3x, for the domain of all integers greater than 0. Since the domain is 1, 2, 3, 4, ..., when you multiply those numbers by 3, to get y, you generate the sequence.

To define the sequence recursively, you must base each new number on the previous number.

Start by stating the first term.

a1 = 3

If you look at the sequence, 3, 6, 9, ..., you see it has a constant difference, and it is an arithmetic sequence, so to generate a term, you need to add 3 to the previous term.

Once we defined the first term to be 3, the next term is a2 = 3 + 3 = 6
Then a3 = 6 + 3 = 9, etc.

To define the sequence recursively, just generalize the addition of 3 to a term to get the next term.

--- Strep throat is caused by Streptococcus bacteria. The amount of bacteria multiplies at a rate of 10^13 per 10^2 hrs. What is the average growth of bacteria per hour?

Answers

The equation is pretty straightforward. Basically, if 10^13 bacteria multiplies in 100 hours. We seek to know how many bacteria multiply per hour. So if 10^13 bacteria mulitply in 100 hours Then X bacteria multiply in an hour. Hence X bacteria * 100 hours = 10 ^13 bacteria * 1 hour. X = 10 ^13 * 1 / 100= 10^(13-2) 10^11. Basically, 10^11 bacterias multiply in an hour.

The average growth of the bacteria per hour is [tex]10^{11}[/tex].

To find the average growth of bacteria per hour, we need to determine the rate at which the bacteria multiply per hour.

Given:

The amount of bacteria multiplies at a rate of [tex]\(10^{13}\)[/tex] per [tex]\(10^2\)[/tex] hour.

We want to find the growth rate per hour.

First, let's find out how much the bacteria multiplies per hour:

If the bacteria multiply by  [tex]\(10^{13}\)[/tex] in [tex]\(10^2\)[/tex] hours, then the average growth per hour can be found by dividing the total growth in [tex]10^{13[/tex] hours by [tex]10^2[/tex].

So, the growth per hour is:

Growth per hour} = [tex]\frac{10^{13}}{10^2}[/tex]

Growth per hour} = [tex]10^{13 - 2}[/tex]

Growth per hour} = [tex]10^{11}[/tex]

Therefore, the average growth of bacteria per hour is [tex]10^{11}[/tex].

A plumber charges $55 for a service call plus $35 per hour. If the plumber's bill was $160, how many hours was he there?

Answers

Well first you have to subtract the 55 bc that the phone call 160-55=105 and den take 105 and divide it by 35 105/35=3 the plumber was there for 3 hours

Answer:

Plumber worked for 3 hours.

Step-by-step explanation:

A plumber charges $55 for a service call plus $35 per hour.

Let he works for x hours.

Then for x hours of work charges = $35x

Since plumber charges $55 as a fixed charge so the total charges will be = 55 + 35x

This total amount charged by the plumber equals to $160

and the equation representing this situation will be

55 + 35x = 160

35x = 160 - 55

35x = 105

x = [tex]\frac{105}{35}[/tex]

x = 3 hours

Therefore, he worked for 3 hours.

How many 2/3 -cup servings are in four cups of pistachios?

Answers

Answer:

4 Of them

Step-by-step explanation:

So an easy way to do this is by adding 2/3 for a while till we hit max. Like this:

2/3+2/3=1 1/3+2/3= 2+2/3=2 2/3+ 2/3= 3 1/3+2/3= 4. so 6 of them

Hope this helps!

Final answer:

To find out how many 2/3-cup servings are in four cups of pistachios, you divide 4 cups by 2/3 cup, which equals 6 servings.

Explanation:

To determine how many 2/3-cup servings are in four cups of pistachios, you would divide the total number of cups by the size of one serving:

Total servings = Total volume \/ Size of one serving = 4 cups / (2/3 cup)

To divide by a fraction, multiply by its reciprocal:

Total servings = 4 / (2/3) = 4 * (3/2) = 4 * 1.5 = 6

So, there are six 2/3-cup servings in four cups of pistachios.

the product of two consecutive even integers is 48 find the integers

Answers

To start, define your variables, x will be the first even integer, and x+2 will be the greater of the two even integers (you would add 2 since even integers are 2 numbers apart). Then, since the product of the two integers is 48, you would set up an equation that looks like this: x(x+2)=48.
Once you simplify, you should get an equation that looks like a quadratic: 
x^2+2x=48. Now, to find the values of x, you have to solve for the roots or zeroes, which means you will have to set the equation to 0. To do this, subtract 48 from both sides and you get: x^2+2x-48=0.
Then, factor the equation and you get: (x+8)(x-6)=0
Now, to solve for x, set each factor to 0, which would look like this:
x+8=0
x-6=0
Now, solve each one for x and you get x=-8 and x=6
Then, to find the pairs for each integer, add 2 to each x and you get that the two sets of integers that equal 48 as their product are -8 and -6; and 6 and 8


The required integers are -8 and -6, or 6 and 8 whose the product of two consecutive even integers is 48

What are Integers?

Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer.

Let the two consecutive even integers be 2n and 2(n+1), where n = any integer.

As per the given condition, The product of the two integers is 48

2n × 2(n+1) = 48            

Multiply out, and subtract 48 from both sides

4n2+4n-48=0                            

Divide both sides by 4

n²+n-12=0                            

Factor the quadratic

(n+4)(n-3)=0                      

n= -4 and +3

For n= -4, 2n = -8 and 2(n+1) = -6.  (-8)(-6) = 48

For n=3, 2n = 6 and 2(n+1) = 8.  (8)(6) = 48

Thus, the required integers are -8 and -6, or 6 and 8.

Deepak is a landscaper who charges $30 for each job he does plus an additional $15 for each hour he works. He only accepts jobs if he will earn at least $90 the job. He writes this inequality to determine x, the number of hours he must work during each job in order to accomplish this.

Answers

 A.) Deepak can only accept jobs that last 4 or more hours.

Step-by-step explanation:

Hope this helps :)

add a thanks...

Final answer:

Deepak must work 4 or fewer hours to earn at least $90 per job.

Explanation:

The question is asking about the inequality that Deepak, a landscaper, writes to determine the number of hours he must work during each job in order to earn at least $90 the job. We can break down the equation as follows:

Let x be the number of hours Deepak works.

The equation can be written as: $30 + $15x ≤ $90.

To solve for x, we subtract $30 from both sides: $15x ≤ $60.

Then, we divide both sides by $15: x ≤ 4.

Therefore, Deepak must work 4 or fewer hours to earn at least $90 per job.

What is the quadrant/axis for (7,-12

Answers

It will be in the bottom right quadrant so it will be in quadrant 4 aka IV

Answer:

[tex]\boxed{Quadrant4}[/tex]

The answer should be found in quadrant four it is.

Step-by-step explanation:

x-axis- is a horizontal axis.

y-axis- is a vertical axis.

x-coordinate- is a horizontal position.

y-coordinate- is a vertical position.

quadrant- is a quarter of the coordinate plane.

origin- is a point of intersection of the two axes.

First you had to find quadrant of (7,-12).

Go to the right at it said seven and then go down to the negative twelve and its should be found in quadrant four.

(7,-12) it should be found in quadrant four.

(-7,-12) it should be found in quadrant three.

(-7, 12) it should be found in quadrant two.

(7, 12) it should be found in quadrant one.

I need help on 22-27

Answers

22-27 would be 5 because ya so hahahhahahahhahaha
Oh, this is really simple m8
Alright, for 22: It doesn't matter how many 0's you add after the main digits (there's an official term for these digits, but I don't exactly recall it at this moment)
BASICALLY, 0's are just being used as placeholders AFTER  the main digits, which in this case is 2.6
So, you can say 2.6, 2.60, 2.600, 2.6000, 2.60000000, but those 0's are meaningless really, because they all REALLY have the same value, 2.6. Your choice that they want is 2.06. You can't toss a 0 between the main digits without changing the value. 
So, 22=2.06

Using the same methods as I said, notice how the main digits in 23 are 4.07. This is unchanging. Anything that gets tossed in between changes the numbers value. The answer they want is 4.70. 

Using the same methods as above, notice how the main digits in 24 are 65.8. The answer they want, the choice that's different, is 65.08

Same thing for 25. The main digits are 37.06, so the choice they are looking for, the only one with a different value, is 37.6

For 26, three decimals that are equivalent: 
For example: .5, .50, .500 are all equal. 

For 27, rewrite these as fractions. That's easy.
In algebra, there are names for anything after the decimal. The first number that comes after the decimal is known as the "tenth", the second is known as the "hundredth", the third is known as the "thousandth", so on. 

Applying that, we can convert these into fractions, using each decimals respective value as the denominator here.

.5 is in the tenth place, so as a fraction it's 5/10
.50 is in the hundredth place total, so as a fraction it's 50/100
.500 is in the thousandths place total (meaning this is where it ends), so it's 500/1000 as a fraction. 
But in the end, ALL of these are the same value, 5/10

[tex]r=xy+h[/tex]

Step-by-step explanation:

[tex]x=\frac{r-h}{y}[/tex]

Solve the equation for h

We need to get 'h' alone

[tex]x=\frac{r-h}{y}[/tex]

multiply y on both sides

[tex]xy=r-h[/tex]

Now add h on both sides

[tex]xy+h=r[/tex]

Subtract xy from both sides

[tex]h=r-xy[/tex]

Now solve the equation for 'r'

[tex]x=\frac{r-h}{y}[/tex]

multiply y on both sides

[tex]xy=r-h[/tex]

Now add h on both sides

[tex]xy+h=r[/tex]

[tex]r=xy+h[/tex]
