the 1560 members of the temecula community church have a method of quickly notifying members. the pastor and his secretary each call 3 members each of whom then call 3 other members, each of whom then calls 3 more members, and so on. how many rounds of calls are needed before all 1560 members are called

Answers

Answer 1

Using an exponential function, it is found that 7 rounds are needed before all 1560 members are called.

What is an exponential function?

An exponential function is modeled as follows:

[tex]y = ab^x[/tex]

In which:

a is the initial value.b is the rate of change.

Considering that initially one person knows the method, and then each person will call 3 other people, the parameters are given as follows:

a = 1, b = 3.

Hence the number of people that are called after x rounds is given by:

[tex]y = 3^x[/tex]

The number of rounds that will take for the 1560 members to be called is found as follows:

[tex]3^x = 1560[/tex]

[tex]\log{3^x} = \log{1560}[/tex]

[tex]x\log{3} = \log{1560}[/tex]

[tex]x = \frac{\log{1560}}{\log{3}}[/tex]

x = 6.69.

Rounding up, as at the end of the 6th call not all members will have been called, 7 rounds are needed before all 1560 members are called.

Samantha works in a department store selling clothing. she makes a guaranteed salary of $500 per week, but is paid a commision on top of her base salary equal to 25% of her total sales for the week. how much would samantha make in a week in which she made $650 in sales? how much would samantha make in a week if she made xx dollars in sales?

Answers

If Samantha works in a department store selling clothing and she makes a guaranteed salary of $500 per week but is paid a commission on top of her base salary equal to 25% of her total sales for the week, then Samantha would make $662.5 in a week in which she made $650 in sales and she would make 500 + 0.25 xx in a week in which she made xx dollars in sales.

The amount of money Samantha makes in a week can be given by an algebraic expression.

Amount of money Samantha makes in a week = Salary per week + 25% of her total sale

Amount of money Samantha makes in a week = 500 + 0.25 x

Here x is the sales Samantha made in a week

If she made $650 in sales in a week :

Amount of money Samantha makes in a week = 500 + 0.25(650)

Amount of money Samantha makes in a week = 500 + 162.5

Amount of money Samantha makes in a week = $662.5

If she made xx dollars in sales in a week :

Amount of money Samantha makes in a week = 500 + 0.25 x

Amount of money Samantha makes in a week = 500 + 0.25 xx

Answers

In Wednesday, the stock market had its biggest loss.

Over the course of a day, the stock market will fluctuate in value due to a number of factors. These include political news and economic data. Over the first four days of the week, this means that Monday through Thursday there is more volatility because these are typically the busiest trading days for stocks.

10.45 - (-18.75) = +29.2

-34.75 - (10.45) = -45.2

-40.89 - (-34.75) = -6.14

On Wednesday the stock value lost -45.2 of its value.

When the stock market loses value, it is usually because there are concerns about a company's future prospects. This can be due to changes in the business environment, new technologies that negatively impact the company's performance, or regulatory issues.

Hence, the stock market lost its most value on Wednesday .

Carpet sells for $4 per square foot and will cost you $616 to recarpet your rectangular room. if your room is 14 feet long, how many feet wide is it?

Answers

When carpet sells for $4 per square foot and will cost you $616 to carpet your rectangular room, if you room is 14 feet long then the width is 11 feet

Given,

The cost of Carpet per square foot = $4

Total cost of the carpet = $616

We know

Area of the rectangle = Length × Width

Length = 14 feet

Consider the width of the rectangular room as x

Then the area of the room = 14x

Total cost of carpet = Area of the rectangular room× Cost of carpet per foot

Substitute the values

14x×4=616

14x=154

x=11 feet

Step-by-step explanation:

Answer:

Step-by-step explanation:

The dependant veriable depends on whatever the independent variable is.

Ryan was offered a job after college earning a salary of $60,000. He will get a raise of $4,000 after each year working for the company.

In this problem, the dependant variable is the salary, because his salary depends on the number of years he's worked.

If you think about it as if it's really happening, it'll make more sense--the longer you work at a job, the more raises you'll get over time.

To put this into an equation, we have to use slope-intercept form: y=mx+b

y is the same as M(x), m is your dependent variable, x is your independent variable, and b is the amount you start with.

Then we just plug the numbers in:

the dependant variable is 4000, independent is the years (which we don't need yet, so it stays as x) and the amount he will start with is 60000

M(x)=4,000x+60000

for M(9), you just plug 9 into x and solve

M(9)=4,000(9)+60000=96,000

Finally, 9 years after being hired, his salary will be 96000 (dollars? I don't know what answer goes here but what you put doesn't really fit)

I really hope I didn't explain that too badly or completely wrong because it's been a bit since I learned this so sorry, but fun fact, I remember doing this exact delta math, and I also remember hating it so good luck

The initial population of a small town was 2.53 thousand. The population grows at a rate of 2.15% each year. After how many years will the population have doubled?

Answers

The number of years that the population has doubled will be 33 years.

What is an exponent?

Consider the function:

y = a (1 + r) ˣ

Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

A little town had a population of 2.53 thousand upon its founding. The population increases by 2.15% annually. Then the equation will be

y = 2.53(1.0215)ˣ

The number of years that the population has doubled will be

2 × 2.53 = 2.53(1.0215)ˣ

2 = (1.0215)ˣ

x ln1.0215 = ln2

x = 32.58 ≈ 33 years

The number of years that the population has doubled will be 33 years.

Lisa's father has a large collection of ties. he has 16 ties and 6 of them are blue. if lisa's father chose a tie at random, what is the probability that the tie would be blue?

Answers

If Lisa's father randomly pick a tie among his 16 ties, the probability it will be a blue one is 3/8

Probability is a measure how likely an event will happen. The probability of an event A is defined as the number of event A divided by the number of all possible outcomes. Mathematically,

P(A) = n(A)/n(S)

Where:

n(A) = number of event A

n(S) = number of all possible outcomes or sample space.

In the given problem:

Number of all ties = 16

Number of blue ties = 6

Hence, when a tie is picked up randomly, the probability it will be a blue one is:

P(blue) = (number of blue ties) / (number of all ties)

P(blue) = 6/16 = 3/8

A unit means one of several things. A unit rate means a rate for one thing. We write it as a ratio with the denominator being one.

For example, if you run 70 meters in 10 seconds,  on average you have run 7 meters in 1 second. Both rates, 70 meters in 10 seconds and 7 meters in 1 second, are ratios, but  7 meters in 1 second are unit rates.

The unitary method is a method in which you find the value of one unit and then the value of a required number of units.

Suppose you go to the market to buy 6 apples. The trader tells you that he is selling 10 apples for Rs 100. In this case, the number of apples is the unit and the price of the apples is the value.

As the rate for 6 hrs. is $57,
