¿What is consumidores terciarios?

They are the ones that feed on carnivores and their parasites.

An example:

When we see a dead bird, a week goes by and then there are only the bones, since as it says they feed on dead birds, that is, they eat everything without leaving anything, whether they are birds, cows or people.

(a) the future value after 9 years is  $7254.76  .

(b) the effective rate of interest is  3.769% .

(c) the time required to reach $10000 is  1.77  years  .

The Continuous Compounding formula for the principal P , rate of interest r , and time t is

A = P×[tex]e^{rt}[/tex]

In the question ,

it is given that

Part(a)  

the amount deposited (P) = $5200

rate percent (r) = 3.7% = 3.7/100 = 0.037

time = 9 years

Amount = 5200×[tex]e^{0.037\times9}[/tex]

= 7254.76

the future value after 9 years is $7254.76   .

Part(b)

the effective rate is calculated using the formula

effective rate = [tex]e^{r}[/tex] - 1

effective rate = [tex]e^{0.037}[/tex] - 1

= 1.03769 - 1

= 0.03769

= 3.769%

Part(c)

the time to reach $10000 is calculated using the formula

10000 = 5200[tex]e^{0.037\times t}[/tex]

[tex]e^{0.037\times t}[/tex] = 10000/5200

[tex]e^{0.037\times t}[/tex] = 100/52

taking ㏑both the sides , we get

0.037×t×㏑(e) = ㏑(100/52)

0.037t = 0.65392

t = 0.65392/0.037

t = 1.76735

t ≈ 1.77 years

Therefore , (a) the future value after 9 years is  $7254.76  .

(b) the effective rate of interest is  3.769% .

(c) the time required to reach $10000 is  1.77  years  .

Bank A grants a shorter payment period and is the least costly, so the Ruffins should take the loan from Bank A.

In finance literature and practice, the loan interest (cost) increases with a more extended payment period.

In other words, a shorter payment period reduces the interest cost of a loan.  The loan cost is also influenced by the amount of the principal and the interest rate.

Down payment = 25%

Interest rate = 11%

Mortgage period = 25 years

2 points at closing

N (# of periods) = 300 months (25 years x 12)

I/Y (Interest per year) = 11%

PV (Present Value) = $142,500 ($190,000 - $47,500)

FV (Future Value) = $0

Results:

Period Payments (PMT) = $1,396.66

Sum of all periodic payments = $418,998

Total Interest = $276,498

Down payment = $47,500 ($190,000 x 25%)

2 points = $2,850 ($142,500 x 2%)

Sum of periodic payments = $418,998

Total costs = $469,348 ($47,500 + $2,850 + $418,998)

Down payment = 15%

Interest rate = 10%

Mortgage period = 30 years

N (# of periods) = 360 months (30 years x 12)

I/Y (Interest per year) = 10%

PV (Present Value) = $161,500

FV (Future Value) = $0

Results:

Period Payments (PMT) = $1,417.28

Sum of all periodic payments = $510,220.08

Total Interest = $348,720.08

Down payment = $28,500 ($190,000 x 15%)

Sum of periodic payments = $510,220.80

Total costs = $538,720.80 ($28,500 + $510,220.80)

Thus, we can recommend the Ruffins should go for a Bank A loan that costs less than Bank B's.

The system of equations representing the amount invested are;

(a) x + y + z = 460,000

(b) 0.065·x + 0.07·y + 0.09·z = 36,350

(c) z = x + y

(d) There is one solution. The man invested $90,000 at 6.5%, $140,000 at 7% and $230,000 at 9%

A system of equations are two or more equations that have variables that are common to the equations in the system.

The questions in the parts (a) to (d) obtained from a similar question are;

(a) An equation stating the sum of the three investments

(b) The equation that states that of the sum of the return is 36,350

(c) The equation that states that the amount invested at 9% equals the sum of the other two investments

(d) Solve the derived system of equations

(a) The amount the man invests in the three rental properties = $460,000

Amount invested in the property that earns 6.5% = x

Amount invested in the property that earns 7% = y

The amount invested in the property that earns 9% = z

The equation that represents the sum of the three investments is therefore;

x + y + z = 460,000...(1)

(b) The equation that represents the sum of the returns from the three investment is found as follows;

6.5% = 0.065, 7% = 0.07, 9% = 0.09

(c) The equation stating the amount invested at 9% equals the sum of the other two investment is; z = x + y...(3)

(d) The system of equations is solved as follows;

From equation (1) and (2), we get;

x + y + z = 460,000

z + z = 460,000

2·z = 460000

· = 460,000 ÷ 2 = 230,000

The amount invested in the property that earns 9% per year is $230,000

Equation (3) indicates;

0.65·x + 0.07·y + 0.09 × 230,000 = 36,350

0.65·x + 0.07·y = 36,350 - 0.09 × 230,000 = 15650

The interest earned in the properties that earn 6.5% and 7% = $15650

0.65·x + 0.07·y = 15650...(4)

x + y = 230000...(5)

Equation (4) and (5) indicates;

y = 230,000 - x

0.065·x + 0.07×(230,000 - x) = 15650

16100 - 0.005·x = 15650

0.005·x = 16,100 - 15,650 = 450

x = 450 ÷ 0.005 = 90,000

The amount invested in the property that yields 6.5% per year = $90,000

Therefore;

The amount invested in the property that earns 7% per year = $230,000 - $90,000 = $140,000

There is one solution, the man invested $90,000 at 6.5%, $230,000 at 7%, and $230,000 at 9%

Herein we find a function whose first derivative has to be found. This can be done by using the following derivative rules:

Derivative of a power

f(x) = c · xⁿ → f'(x) = n · c · xⁿ ⁻ ¹

Chain rule

f[g(x)] = (df / dg) · (dg / dx)

Derivative of a sum of functions

d / dx [f(x) + g(x)] = df / dx + dg /dx

Derivative of the sine

d / dx [sin x] = cos x

Now we proceed to find the derivative of the function:

f'(x) = 2 · [√(x + x²) + 3 · sin 3x]² · [(1 + 2 · x) / [2 · √(x + x²)] + 9 · cos 3x]

And we evaluate the derivative at x = 1:

f'(1) = 2 · [√(1 + 1²) + 3 · sin 3]² · [(1 + 2) / [2 · √(1 + 1²)] + 9 · cos 3]

According to the given percentage, the shipping and handling fee that Elizabeth will pay is $16.6

Percentage:

Percentage refers one-hundredth (1/100) of something. And it refers to the rate or proportion of that one hundred.

Given,

Elizabeth buys a microscope priced at $83. Shipping and handling are an additional 20% of the price.

Here we need to find the shipping and handling will Elizabeth paid.

We know that, the price of the product is $83.

And the charges for the shipping and handling is 20%.

So, it can be written as the following form,

=> Additional charges = 20% of 83

=> Additional charges =  20/100 x 83

=> Additional charges = 20 x 0.83

The factoring of the polynomial f(x) = x^4 + 3x³ - 2x² + 48x - 288 is given as follows:

f(x) = (x - 4i)(x + 4i)(x + 6)(x - 3).

The polynomial is factored by it's linear factors, given as follows:

f(x) = (x - x')(x - x'')(x - x''')(x - x'''').

In which x', x'', x''' and x'''' are the roots of the polynomial f(x).

In this problem, we have that -4i is a root, hence, by the Conjugate Roots Theorem, 4i is also a root and hence:

f(x) = (x - 4i)(x + 4i)(x - x''')(x - x'''').

f(x) = (x² + 16)(x - x''')(x - x'''').

As a fourth order polynomial can be the product of two second order polynomials, hence:

x^4 + 3x³ - 2x² + 48x - 288 = (x² + 16)(ax² + bx + c)

x^4 + 3x³ - 2x² + 48x - 288 = ax^4 + bx³ + (c + 16)x² + 16bx + 16c.

Hence the coefficients are given as follows:

Then the equation for the final two factors is:

x² + 3x - 18 = 0.

Which is simplified as follows:

x² + 3x - 18 = (x + 6)(x - 3).

Hence the simplified polynomial is:

There are no extraneous solutions when plugging -7 into x-5=2(x+1).

So extraneous solutions means the solutions that you get by solving an equation, but after you try plugging it back into your original equation, the solution does not work.

Now we have our solutions of x=7, and we just need to check whether it is extraneous or not. We can do this by taking x=1 and plugging it back into your original equation  x - 5 = 2(x + 1)

x - 5 = 2(x + 1)

-7 - 5 = 2(-7 + 1)

-12 = -14 + 2
