Population growth the population of knoxville is 500,000 and is increasing at the rate of 3.75% each year. approximately when wi

Shalnov [3]

Current population = 500,000
Populaton is
500,000 * (1.0375) after 1 year
500,000 * (1.0375)² after 2 years
...
500,000 * (1.0375)ˣ after x years

Therefore when the population reaches a million,
500,000 * (1.0375)ˣ = 1,000,000
1.0375ˣ = 2
x ln(1.0375) = ln(2)
x = ln(2) / ln(1.0375) = 18.83 years

Answer: 18.8 years, or approximately 19 years.

1. Can cross multiplication be used to solve this problem? Why or why not?<br><br><br> HELP

garri49 [273]

Answer:

Step-by-step explanation:

Cross multiplication can be used but not in the beginning. First x should be isolated.

$3 +\frac{5}{x}=\frac{7}{x}\\\\$

Now subtract $\frac{5}{x}$ from both sides

$3 = \frac{7}{x}-\frac{5}{x}\\\\3=\frac{7-5}{x}\\\\3=\frac{2}{x}$

In this stage, cross multiplication can be used.

$\frac{3}{1}=\frac{2}{x}\\\\3*x=2*1\\\\x = \frac{2}{3}$

W=Y(b+A) , for b <br> Solve the equation for the specified variable which is b

arsen [322]

Answer:

$b=\dfrac{W}{Y}-A$

Step-by-step explanation:

As with any "solve for ..." problem, you undo what is done to the variable of interest. Here, what is done is ...

A is added
the sum is multiplied by Y

You "undo" these operations in reverse order (from the bottom of the list up). To undo multiplication, you multiply by the reciprocal:

$W\dfrac{1}{Y}=Y(b+A)\dfrac{1}{Y}=b+A$

To undo the addition of A, add the opposite of A:

$\dfrac{W}{Y}-A=b+A-A\\\\b=\dfrac{W}{Y}-A$

Choose the correct Set-builder form for the following set written in Roster form: { − 3 , − 2 , − 1 , 0 , 1 }

ohaa [14]

The correct Set-builder form of the set that is written in Roster form is {x|x is an integer and -3≤x≤1}.

<h3>What is an integer?</h3>

An integer is a number that can be written without using a fractional component. Integers such as 21, 4, 0, and 2048 are examples.

The correct Set-builder form of the set that is written in Roster form can be written as,

{x|x is an integer and -3≤x≤1}

Hence, The correct Set-builder form of the set that is written in Roster form is {x|x is an integer and -3≤x≤1}.

Jennifer is flying her kite and I get stuck in a tree. She knows the string on her coat is 17 feet long and she is 7 feet from t

babunello [35]

Answer:

15.5 feet

Step-by-step explanation:

Find attached to this answer the appropriate diagram.

We would be using the Pythagoras Theorem to solve this question

The formula is given as:

a² + b² = c²

Where a = opposite side

b = adjacent side

c = hypotenuse

From the question,

a = opposite side = unknown

b = adjacent side = 7 feet

c = hypotenuse = 17 feet

We are to find the opposite side

Using the formula

a² + b² = c²

a² = c² - b²

a² = 17 feet² - 7 feet ²

a² = 289 feet² - 49 feet²

a² = 240 feet²

a = √240 feet²

a = 15.491933385 feet

Approximately 15.5 feet

Therefore, the kite is 15.5 feet high up in the tree.
