A city has a population of 320,000 people. Suppose that each year the population grows by 3.5%. What will the population be after 12 years?
Use the calculator provided and round your answer to the nearest whole number.

Answers

Answer 1
First find what 3.5% is of 320,000 is. That is 11,200. If it grows by 3.5% each year for twelve years, then it is growing by 11,200 * 12. Over 12 years the growth is 134,400. Total population would then be 320,000 + 134,000 so 454,400.
Answer 2

Answer is 483,542

Compound Interest:

The formula for compound interest is   [tex]A = p(1 + \frac{r}{n} )^{nt}[/tex]

where P is the principal balance

r is the interest rate

n is the number of times interest is compounded per time period.

t is the number of time periods.

(Given),

P = 320,000

n = 1

t = 12

r = 3.5% = 3.5 / 100 = 0.035

[tex]A = 320,000 (1 + 0.035)^{12}[/tex]

[tex]A = 320000(1.035)^{12}[/tex]

A = 483,541.970 (approx)

A = 483,542 (Rounded to the nearest whole number).

What is the solution to this 2b+9 when b=3

Answers

Answer:

15 :D

Step-by-step explanation:

Well, we know b = 3 so we can rewrite the expression to make it less confusing. So, we change b for 3, which is the same thing but number form:

solve the log equation:
log_(4)(x+5)+log_(4)(x-1)=2

Answers

X=3

Solve by re-writing in exponential form using the definition of logarithm and simplifying.

By applying logarithmic properties and solving a resulting quadratic equation, we find the solutions x = 3  and x = -7 for the given logarithmic equation.

To solve the logarithmic equation [tex]\( \log_4(x+5) + \log_4(x-1) = 2 \),[/tex] we can use the properties of logarithms to condense the equation into a single logarithm, then solve for x.

First, we apply the product rule of logarithms, which states that [tex]\( \log_a(b) + \log_a(c) = \log_a(bc) \)[/tex], to condense the two logarithms on the left side:

[tex]\[ \log_4((x+5)(x-1)) = 2 \][/tex]

Now, we have:

[tex]\[ (x+5)(x-1) = 4^2 \][/tex]

[tex]\[ (x+5)(x-1) = 16 \][/tex]

Next, we expand the left side of the equation:

[tex]\[ x^2 - x + 5x - 5 = 16 \][/tex]

[tex]\[ x^2 + 4x - 5 - 16 = 0 \][/tex]

[tex]\[ x^2 + 4x - 21 = 0 \][/tex]

Now, we can solve this quadratic equation for x. We can use the quadratic formula:

[tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]

For [tex]\( x^2 + 4x - 21 = 0 \), \( a = 1 \), \( b = 4 \), and \( c = -21 \).[/tex]

Plugging in these values, we get:

[tex]\[ x = \frac{-4 \pm \sqrt{4^2 - 4(1)(-21)}}{2(1)} \][/tex]

[tex]\[ x = \frac{-4 \pm \sqrt{16 + 84}}{2} \][/tex]

[tex]\[ x = \frac{-4 \pm \sqrt{100}}{2} \][/tex]

[tex]\[ x = \frac{-4 \pm 10}{2} \][/tex]

[tex]\[ x = \frac{6}{2} \][/tex] or [tex]\( x = \frac{-14}{2}[/tex]

x = 3  or x = -7

So, the solutions to the equation are  x = 3  and x = -7 .

Round the fraction 7 4/5 to the nearest whole number

Answers

The correct answer is: 8

Explanation:

Given mixed number:

[tex] 7\frac{4}{5} [/tex]

In order to convert a mixed number into a decimal number, follow the steps mentioned below:

Multiple 7 with 5 and add the numerator to the answer you get by multiplying 7 with 5. After that, write that result in the numerator and divide it with 5:

Step-1:

Multiply 7 with 5.

7*5 = 35

Step-2:

Add numerator value, which is 4 in this case, in 35

35 + 4 = 39

Step-3:

Rewrite the fraction.

[tex] \frac{39}{5} [/tex]

Step-4:

Calculate.

[tex] \frac{39}{5} = 7.8 [/tex]

Now, as the number at the tenth place after the decimal point is greater than 5, we have to round it off to 8.0.

Hence the correct answer is 8.

Rounding 7 4/5 to the nearest whole number gives 8.

To round the fraction 7 4/5 to the nearest whole number, we examine the fractional part (4/5) of the mixed number.

The fractional part, 4/5, is greater than or equal to 1/2. In such cases, when the fractional part is greater than or equal to 1/2, we round the whole number up to the next higher whole number.

In this case, the whole number part is 7. Since the fractional part is greater than 1/2, we round the whole number up to the next higher whole number, which is 8.

Therefore, rounding 7 4/5 to the nearest whole number gives us 8.

In summary, when rounding a mixed number to the nearest whole number, we look at the fractional part. If it is greater than or equal to 1/2, we round the whole number up. If it is less than 1/2, we round the whole number down. In this case, since 4/5 is greater than 1/2, we round 7 up to 8.

Use complete sentences to describe how a postulate becomes a theorem.

Answers

A postulate becomes a theorem when it is proven by a series of logical steps to a valid outcome. Typically, a postulate is a statement that is presumed to be true without proof, whereas a theorem is a true statement that can be proven

A postulate becomes a theorem through logical deduction and proof, starting with the postulates and leading to an indisputably true conclusion. Each step in a proof must follow logically from the ones before it, and the end result is a statement that holds true without premises, recognized universally in mathematics.

A postulate becomes a theorem through a process of logical deduction and proof. In mathematics, a postulate is an assumed statement used as a starting point for further reasoning and arguments. When we begin with our starting definitions and postulates, we can logically deduce new conclusions or theorems. If we can provide a proof of a statement A and show that it is definitely true based on the postulates and previously established theorems, then A becomes a theorem. Each line in a proof must follow from the rules cited, which are based on earlier lines of the proof or established logic. Once we derive the final conclusion, if every line of the proof is legitimate, then the whole proof is legitimate, and the sentence can be considered a theorem.

Moreover, a theorem is a statement that is true without any premises, meaning it derives from logical deductions of the initial assumptions. A theorem is proven via indisputable, step-by-step logical deductions. To illustrate, if an experiment or an established fact contradicts existing theories, it may lead to the development of a new theorem, as was the case with the postulates of Special Relativity. Ultimately, something is recognized as a theorem if it is a tautology—true in all possible models—thus making it a universally accepted truth in mathematics.


write a quadratic function in standard form with zeros 6 and -8

Answers

Final answer:

To write a quadratic function in standard form with zeros 6 and -8, we use the fact that the zeros of a quadratic function are the values of x for which the function equals zero. The quadratic function in standard form with zeros 6 and -8 is x^2 + 2x - 48 = 0.

Explanation:

To write a quadratic function in standard form with zeros 6 and -8, we use the fact that the zeros of a quadratic function are the values of x for which the function equals zero. The standard form of a quadratic function is ax^2 + bx + c = 0. Since the zeros are 6 and -8, the factors of the quadratic function will be (x - 6) and (x + 8). Multiplying these factors gives us (x - 6)(x + 8) = 0. Expanding and simplifying this expression, we get x^2 + 2x - 48 = 0. Therefore, the quadratic function in standard form with zeros 6 and -8 is x^2 + 2x - 48 = 0.

Final answer:

The student's question is about simplifying a complex algebraic expression that involves exponents and basic arithmetic operations. The approach to simplification entails applying the rules of exponents and arithmetic operations systematically.

Explanation:

The student's question appears to involve simplifying an algebraic expression with exponents and performing operations such as division and multiplication. While the question contains parts that are not directly relevant to the simplification process, we can still address the general approach to simplify an expression like a^4 divided by 2a^2 and then multiplied by 4a^4 times 8a^3, plus an additional term 1/2a plus 4a^2.

To simplify such an expression, one would apply the rules of exponents and arithmetic operations step by step. For instance, when dividing exponents with the same base, you subtract the exponents, and when multiplying, you add the exponents. This process typically results in a much simpler expression that can easily be understood or further manipulated.

Answers

So far team has won =(60/100)*20 = 12 gamesTotal games played in season =5080 percent of the remaining games won = 80 percent of (50-20) = (80/100)*30 = 24 games.Total game won this season = 36So, percent games won in the entire season = (36/50)*100=72%Answer (4)

Answer:  Option '4' is correct.

Step-by-step explanation:

Since we have given that

Total number of games =50

Firstly, he played 20 games.

Percentage of games they won = 60%

Number of games they won is given by

[tex]\dfrac{60}{100}\times 20\\\\=0.6\times 20\\\\=12[/tex]

Remaining number of games = 50-20=30

Percentage of remaining games they won = 80%

So, number of games they won is given by

[tex]\dfrac{80}{100}\times 30\\\\=0.8\times 30\\\\=24[/tex]

So, total number of games they won is given by

12+24 = 36

So, Percentage of games they won for the entire season will be

[tex]\dfrac{36}{50}\times 100\\\\=36\times 2\\\\=72\%[/tex]

Hence, Option '4' is correct.

The volume of the rind is growing at the rate __?__ cubic centimeters per week at the end of the fifth week. Assume that the radius is initially zero. ...?

Answers

 The volume of a sphere is V = 4/3 x pi x r^3 

The rind volume is the difference of two spheres. The radius of the inner sphere volume is, r - .1 r or .9 r. So the volume of the rind is 

V = 4/3 x pi x r^3 - 4/3 x pi (.9 r )^3 

V = 4/3 x pi x r^3 - 4/3 x pi x (.9^3) x r^3 

Implicitly differentiating both sides with respect to t yields: 

V' = ( 4 x pi x r^2 x r' ) - ( 4 x pi x (.9^3) x r^2 x r' ) 

This equation define the rate of change of the rind volume with respect to time. 

As defined in the problem, r' = 2 

As well, after 5 weeks the radius will be r = 2 * 5 = 10 

V' = (4 x pi x 10^2 x 2) - (4 x pi x (.9^3) x 10 x 2) 

V' = (800 x pi) - (800 x pi x (.729)) 

V' = (800 x pi) (1 - .729) 

V' = (800 x pi)(.271) 

V' = 681.09 cubic centimeters

Final answer:

To find the rate at which the volume of the rind is growing, we calculate the volume of the entire watermelon and the volume of the watermelon not including the rind, at the end of the fifth week. Then, calculate the derivative of this volume difference with respect to time.

Explanation:

The topic at hand is related rates in calculus, specifically applied to a growing spherical watermelon. The rate of growth of the radius is given as 2 centimeters per week. The thickness of the rind is always one-tenth the radius, but we're interested in the volume of the rind. We use the formula for the volume of a sphere: V = (4/3)πr³, where r is the radius.

At the end of the fifth week, the radius is 2 cm/week x 5 weeks = 10 cm, therefore the outer radius of the watermelon is 10 cm and the inner radius is 9 cm (since the rind is one-tenth the radius). Therefore, the volume of the rind would be given by the volume of the watermelon minus the volume of the interior of the watermelon not including the rind. We can then calculate the derivative of the volume of the rind with respect to time to find the rate at which the volume is increasing at the end of the fifth week.

Given dy/dt=4y and y(2)=400. Find y(7).

Answers

Final answer:

To find y(7) given dy/dt = 4y and y(2) = 400, we can solve the differential equation, find the constant of integration, and substitute the value of t to find y(7).

Explanation:

To solve the differential equation dy/dt = 4y, we can separate the variables and integrate them. Starting with dy/y = 4dt, we get ln|y| = 4t + C, where C is the constant of integration.

Using the initial condition y(2) = 400, we can solve for C: ln|400| = 4(2) + C, C = ln|400| - 8. Now we can find y(7): ln|y(7)| = 4(7) + ln|400| - 8. Exponentiating both sides, we get |y(7)| = e^(28 + ln|400| - 8), and since y(7) is positive, y(7) = e^(28 + ln|400| - 8).
