Elon sent a chain letter to his friends, asking them to forward the letter to more friends. The relationship between the elapsed time, t, in days, since Elon sent the email, and the total number of people who receive the email, P(t), is modeled by the following function: P(t)=4×3^t​

Answers

Answer 1

Answer:

Growing by 3's

Step-by-step explanation:

Answer 2

Every day, the number of people who receive the email increases by a factor of 3.

We have,

In the function, P(t) = [tex]4 \times 3^t,[/tex] the base of the exponent is 3.

This means that for each additional day (t), the exponent increases by 1, and multiplying by 3 represents the growth factor.

For example, if we consider t = 0 (the day Elon sent the email), we substitute t = 0 into the function:

P(0) = 4 * [tex]3^0[/tex] = 4 * 1 = 4

On the first day, 4 people received the email.

If we consider t = 1 (the day after Elon sent the email):

P(1) = 4 * [tex]3^1[/tex] = 4 * 3 = 12

On the second day, the number of people receiving the email increased by a factor of 3 (from 4 to 12).

Similarly, on the third day:

P(2) = 4 * 3² = 4 * 9 = 36

The number of people receiving the email increased by a factor of 3 (from 12 to 36).

This pattern continues, and for each additional day, the number of people who receive the email increases by a factor of 3.

Therefore,

The number of people who receive the email increases by a factor of 3 every day.

Answers

Answer:

x=5

Step-by-step explanation:

-6 - 2(4x - 7) = -32

Distribute -2

-6 - 8x +14 = 32

Combine Like Terms

-8x + 8 = -32

Subtract 8 from both sides

-8x = -40

Divide each side by -8

Answers

Answer:

PQ=30

Step-by-step explanation:

Knowing that the segment has 3 parts that are 3:1:1 and sum up to 50, you could find how much 1 would equal by finding the total in relation to the ratio (doing 3+1+1) which gets you 5 parts. Then you can divide the total (50) by 5 to figure out how much one part would equal (10). Now, since you know that 1 part is equal to 10 and that PQ is 3 parts, you can find that PQ is equal to 3x10, or 30.

Joe Howard earns an annual gross pay of $955,520 as a
professional baseball player. He is married with 4 dependents.
How much is withheld from his monthly paycheck for state
income tax?

Answers

Answer: 3924.25

Step-by-step explanation:

0.0150x1000=15

0.0300x2000=60

0.0450x2000=90

0.0500x938520=46926

Add the numbers

47091÷12=3924.25

Additional work:

955520-12000=943520-1000=942520-2000=940520-2000=938520

His monthly paycheck for state income tax is $19,906.65.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For exmaple, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Annual Gross pay = 955520

He is married with 4 dependents.

So, every month he earn

= 955520/12

= 79,626.6

and, Also have 4 dependents

= 79,626.6 /4

= 19,906.65

Hence,  his monthly paycheck for state income tax is $19,906.65.

1.Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.

How many miles does the first cyclist bike in 45 minutes?

Answers

Answer:

9 miles

Step-by-step explanation:

If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.

30+15=45

6+3=9

The first cyclist bikes 9 miles in 45 minutes.

Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:

60 = 12 45 = X 45 x 12/60 = X 540/60 = X 9 = X

Therefore, the first cyclist bikes 9 miles in 45 minutes.

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

ax² + bx + c = 0

Step 1 :

ax² + bx + c = 0

Step 2 : Subtracting c on both sides , we get

ax² + bx = -c

Step 3 : Divide by x on both sides , we get

ax + b = -c/x

Hence , the steps are true in solving the quadratic equation

Both chemical and physical changes affect the state of matter. Physical changes are those that do not change the make-up or identity of the matter. For example, clay will bend or flatten if squeezed, but it will still be clay. Changing the shape of clay is a physical change, and does not change the matters identity. Chemical changes turn the matter into a new kind of matter with different properties. For example, when paper is burnt, it becomes ash and will never be paper again. The difference between them is that physical changes are temporary or only last for a little while, and chemical changes are permanent, which means they last forever. Physical and chemical changes both affect the state of matter.Passage #2 The Best PB & J EverWhen I got home from school after a long boring day, I took out the peanut butter, jelly, and bread.

At the age of 13 he won the U.S. Junior Chess Championship, becoming the youngest Junior Champion ever. At the age of 14 he won the U.S. Championship and became the youngest U.S. Champion in history. Fischer would go on to become the World Champion of chess, but he would also grow to become his own worst enemy.

The crisis was actually the result of a combination of many complex factors. First, easy credit conditions allowed people who were high-risk or unworthy of credit to borrow, and even people who had no income were eligible for large loans. Second, banks would bundle these toxic loans and sell them as packages on the financial market. Third, large insurance firms backed these packages, misrepresenting these high-risk loans as safe investments. Fourth, because of the ease of acquiring credit and the rapid growth in the housing market, people were buying two or three houses, intending to sell them for more than they paid. All of these factors created bubbles of speculation. These bubbles burst, sending the whole market into a downward spiral, causing employers to lose capital and lay off employees. Consumer spending then plummeted and most businesses suffered. The economy is like a big boat, and once it gets moving quickly in the wrong direction, its hard to turn it around.
