The number of acres owned for which the average intake is 2200 calories per day is 2 acres obtained by the algebraic expression that relates the acres of land and the calories per day.

What is an algebraic expression?An algebraic expression is formed by variables, constants, and arithmetic operations. An algebraic expression provides the relation between the input and output variables i.e., x and f(x) respectively.Calculation:

It is given that, the number of calories consumed daily by a person owing x acres of land is given by the algebraic expression,

C(x) = 270 ln(x+1) + 1900

The average intake of calories consumed per day is given by C(x) = 2200

Here x is the number of acres of land. Then, the required number of acres of land is

C(x) = 270 ln(x+1) + 1900

⇒ 2200 = 270 ln(x+1) + 1900

⇒ 270 ln(x+1) = 2200 - 1900

⇒ 270 ln(x+1) = 300

⇒ ln(x+1) = 300/270 = 10/9

Applying base 'e' on both sides, we get

⇒ (x+1) = [tex]e^\frac{10}{9}[/tex]

⇒ x+1 = 3.0377

⇒ x = 3.0377 - 1 = 2.0377

When rounding the final answer to the nearest tenths, we get x = 2 acres.

When rounding the final answer to the nearest thousand, we get x = 2.038 acres.

Thus, for an average intake of 2200 calories per day, the number of acres of land owned is approximately 2 acres.

Step-by-step explanation:

If you are looking for the total amount spent, first we will convert 2 3/4 into a decimal, which is 2.75. 2.75 X 19.50 = 53.625. She bought 53.525 dollars worth of blue paint, now we solve for orange. 1 1/3 X 16 = 64/3, which is simplified to 21 1/3. If we add the two togetherwe get 74.9583, but the 3 is repeated. If you are asked to rount to the 100th place, the asnwer is $74.96. If you are rounding to nearest dollar, it is about $75.

a. What was the population of the state in 2000 ?
b. When will the population of the state reach 26.6 million?

Answers

The population of the state 2,000 is 18.5 Million. And the time at which the population of the state reaches 26.6 million will be 2.126 years.

What is an exponent?

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The equation is given below.

[tex]\rm A = 18.5 \times e^{0.1708\times t}[/tex]

The population of the state in 2,000 is calculated as,

[tex]\rm A = 18.5 \times e^{0.1708\times 0}[/tex]

A = 18.5 × e⁰

A = 18.5 Million

The time at which the population of the state reaches 26.6 million will be given as,

[tex]\rm 26.6 = 18.5 \times e^{0.1708\times t}\\\\1.4378 = e^{0.1708\times t}[/tex]

Take natural log on both sides, then we have

0.1708 × t = ln 1.4378

t = 2.126 years

The population of the state 2,000 is 18.5 Million. And the time at which the population of the state reaches 26.6 million will be 2.126 years.

The length of the rectangle is 16 units,

The diagonal, D, of a rectangle is given by

D = √(l² + w²)

Where l is the length of the rectangle

and w is the width of the rectangle

l = 16

w = 12

Thus,

The diagonal of the rectangle is

D = √(16² + 12²)

D = √(256 + 144)

a. In 2000 , the population of the state was ? million.

Answers

The population of the city in 2000 = 23.1 million

In 2006 the population will be equal to 28.3 million

Applications of Compound interest:

Compound interest may be used in a variety of situations, including increasing or decreasing population, Increasing the count of bacteria increasing an item's value, and a decrease in an item's worth.  

The formula for Compound interest is given by

                            A = Pe^rt

Where P = Principal amount or Initial value

r = rate of interest or increase

t = time period

Here we have

The formula [tex]A = 23.1 e^{(0.0152t)}[/tex] represents the population of a US state, A, in millions, 't' years after 2000.  

Here we need to solve the following questions

a. What was the population of the state in 2000

Compare the given formula with A = Pe^rt  

=>  [tex]23.1 e^{0.0152t} = Pe^{rt}[/tex]    

=> Initial value or initial population, P = 23.1 and

rate of increase r = 0.0152  

Therefore,

The population of the city in 2000 = 23.1 million

b. When will the population of the state reach 28.3 million?

As we know in 2002 the population = 23.1 million

Let's assume that after 'n' year the population will become 28.3 million

As we know Rate of increase = 0.0152    

From the given formula

Population of the city after n, A = 23.1 e^(0.0152n)  

As we assumed the population after n years = 28.3

=>  23.1 e^(0.0152n)  = 28.3

=> e^(0.0152n)  = 28.3/23.1

=> e^(0.0152n) = 1.225  

Apply log on both sides

=> log e^(0.0152n) = log 1.225  

=> 0.0152n log e = log 1.225  

=> 0.0152n (1) = 0.0881    

=> n = 0.0881/0.0152

=> n = 5.8 ≅ 6

After 6 years the population will be 28.3 million

After 6 years i.e 2000 + 6 = 2006  

Therefore,

In 2006 the population will be equal to 28.3 million
