What is Pythagorean Theorem?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic Euclidean geometry relationship between a right triangle's three sides. According to this rule, the area of the square with the hypotenuse side is equal to the sum of the areas of the squares with the other two sides.

Here, the two sides of the triangle are, 7 and 11.

By Pythagorean theorem,

[tex]7^2 + 11^2 = x^2\\49 + 121 =x^2 \\170 = x^2\\x = \sqrt{170} \\[/tex]

Hence, the value of x is [tex]\sqrt{170}[/tex].

Here, the sum of two sides of triangle is not a perfect square.

Therefore, the side lengths is not a Pythagorean triple.

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

=> Additional charges = 16.6

Therefore, the shipping and handling charges is $16.6

An equation of the line that began with a y-intercept of (0, 4), shifted up 3 units, and is perpendicular to y = 3/4(x) - 2 is: A. y = -4/3(x) + 7.

Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

In Mathematics, the condition for perpendicularity of two lines is given by m₁ × m₂ = -1. Next, we would determine the slope of this equation that began with a y-intercept of (0, 4):

3/4 × m₂ = -1

3m₂/4 = -1

3m₂ = -4

m₂ = -4/3

In order to determine the new y-intercept, we would translate the equation by shifting it 3 units up:

Translation = y + 3 = 4 + 3 = 7.

Now, we can write this equation in slope-intercept form as follows:

y = mx + c

y = -4x/3 + 7 or y = -4/3(x) + 7.

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)

Answer:

x=-1/13

Step-by-step explanation:

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:

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

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

Derivative of the sine

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]

By changing both equations to slope-intercept, it is easier to determine whether two lines are perpendicular.

Since [tex]y = \frac{5}{2} x+ 5[/tex] is already in slope-intercept form, we just need to change the first given equation.

2x + 5y + 3 = 0

2x + 5y = -3

5y = -2x -3

[tex]y=\frac{-2}{5}x-\frac{3}{5}[/tex]

Two lines are perpendicular when the slope of the lines (coefficient of x) are negative reciprocals (opposite sign of the inverse of a number).

Comparing the two slopes [tex]\frac{5}{2}[/tex]  and [tex]\frac{-2}{5}[/tex], we can see they they both fit the criteria of being opposite signs and inverses of each other.

So  2x + 5y + 3 = 0 is perpendicular to y = (5/2)x+ 5.

(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

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes

We have a random variable having a value greater than 7

Now -

Number of outcomes favorable to event A = (-∞, + ∞) - (- ∞, 7)

Total number of outcomes for event A = (-∞, + ∞)

P(A) = (-∞, + ∞) - (- ∞, 7) /  (-∞, + ∞)

P(A) = ∞/∞
