Answer: (-4, 1)

Step-by-step explanation:

To solve graphically, change each equation into slope-intercept form

(y = mx + b)

3x + 4y = -8

+8 +8

3x + 4y + 8 = 0

-4y -4y

3x + 8 = -4y

Divide both sides by -4 to get y by itself

-3/4x - 2 = y or y = -3/4x - 2

Do the same for the other equation.

-x + y = 5

+x +x

y = 5 + x or y = x + 5

Plug in the equations graphically. The point at which the two lines intercept is your answer.

The air speed of the plane to cover 360 miles against the wind and with the wind in the given time is equal to 200 miles per hour.

Let 'x' be the speed of the plane fly in still air.

And 'y' be the speed of the wind.

Speed against the wind = x - y

Speed with the wind = x + y

Total distance covered by plane = 360 miles

Time taken against the wind = 2 hours 15 minutes

                                               = 2 ( 1/4 ) hours

                                               = 9 / 4 hours

Time taken with the wind = 1 hour 30 minutes

                                          = 1 ( 1/2 ) hours

                                          = 3 /2 hours

Speed = distance / time

Against the wind :

x - y = 360 / (9 /4 )

⇒x - y = 160___(1)

With the wind:

x + y = 360 / (3 /2)

⇒x + y = 240 ___(2)

Add (1) and (2) we get,

2x = 400

⇒ x= 200miles per hour

⇒y = 40 miles per hour

Therefore, the air speed of the plane as per given condition is equal to 200miles per hour.

The sample should be milled to a radius that is approximately 7.19 times its original radius in order to increase its work function by 2%.

The work function of a material is related to its surface area, and milling a sample into smaller nano-spheres increases its surface area. The increase in work function can be approximated by the following equation:

ΔW = kTln(A/A₀)

where ΔW is the change in work function, k is Boltzmann's constant, T is the temperature in Kelvin, A is the new surface area of the milled sample, and A₀ is the original surface area of the sample.

To find the size to which the sample should be milled to increase its work function by 2%, we need to rearrange the equation to isolate the new surface area:

A/A₀ = e^(ΔW/kT)

Plugging in the known values, we get:

A/A₀ = e^(0.02 * 5.1 eV / (8.62 * 10⁻⁵ eV/K * 300 K))

= 51.64

The new surface area is 5064% larger than the original surface area.

Since the sample is being milled into nano-spheres, the new surface area is proportional to the square of the radius. Let's call the original radius of the sample "r₀". Then the new radius is:

r = √(A/A₀) * r₀ = √(51.64) * r₀ = 7.19 * r₀

For f(x) =4x+1 and g(x) = x²-5, the answer of (f/g) (x) is D) 4x+1/x²-5, x≠±√5

From the question, we have:

f(x) =4x+1

g(x) = x²-5

If what you are looking for is( f/g) (x), then only place the value of f(x) as the quantifier and g(x) as the denominator. Then the function that satisfies is D.

But here there is a condition that (f/g) (x) applies if the value of x is not √5 or -√5. Because if it becomes an x value then the result will be 0.

We can prove this:

With this equation (f/g) (x)=4x+1/x²-5

let's try to use value of x is √5, it will be

(f/g) (x)=4x+1/x²-5

(f/g) (√5) = 4.√5+1/(√5)²-5

=(4√5+1)/5-5

=(4√5+1) /0

=0

Then, try to use value of x is -√5, it will be

(f/g) (x)=4x+1/x²-5

(f/g) (√5) = 4.(-√5)+1/(-√5)²-5

=(-4√5+1)/5-5

Answer:

Step-by-step explanation:

The factored form of a polynomial function with roots r1 and r2 can be found by multiplying two linear factors (x - r1) and (x - r2).

Here are the steps to find the factored form of the polynomial function with roots 3i and 2:

Write the first linear factor: (x - 3i)

Write the second linear factor: (x - 2)

Multiply the two linear factors: (x - 3i)(x - 2)

Expand the product to find the polynomial function:

x^2 - (3i + 2)x + (3i * 2) = x^2 - 2x - 6i

It is possible to choose a and b such that the value of function(x) at any given point is equal to the limit of f(x) as x approaches any value. This guarantees that f is continuous throughout.

A function's limit as x approaches any value must match the value of f(x) at that moment in order for the function to be continuous everywhere. In order to ensure that this need is satisfied, the values of a and b that make up f(x), whether it be a linear equation, polynomial, or another sort of equation, must be chosen. Since the behaviour of the function varies smoothly as x approaches any value, this ensures that the function is continuous throughout. In other words, a and b values must be selected in a way that the function is continuous, i.e., defined and devoid of breaks or discontinuities.

To make solving this problem easier, we need to consider the ages of Mr Lim and his son. For example by multiplying the number x.

Let:

Mr Lim's age = a

His son's age = b

So that,

The ratio of ages in the current year:

Mr Lim's age to his son's age = 5x : 2x

a : b = 5x : 2x

The ratio of ages in the four years ago:

Mr Lim's age to his son's age = 3x : x

(a - 4) : (b - 4) = 3x : x

[tex]\frac{a-4}{b -4} =\frac{3x}{x}[/tex]

[tex]\frac{5x-4}{2x -4} =\frac{3x}{x}[/tex]

[tex]\frac{5x-4}{2x -4} =\frac{3}{1}[/tex]

5x - 4 = 6x - 12

5x - 6x = -12 + 4

-x = -8

x = 8

So that we know the age of Pak Lim's and the age of his son's this year.

Mr Lim's age = 5x

                     = 5 × 8

                     = 40 years old

His son's age = 2x

                     = 2 × 8

                     = 16 years old

After that, we find Mr Lim's age 6 years from now by adding 6 years to this year's age.

Mr Lim's age be in 6 years time = 40 + 6

                                                    = 46 years old

Answer:

Step-by-step explanation:

The monthly payment on a loan and the total interest that will be paid during the term of the loan can be found using an amortization formula.

Here are the steps to find the monthly payment and total interest for the given loan conditions:

Convert the interest rate to a decimal: 7.5% = 0.075

Divide the interest rate by the number of periods (months) per year: 0.075 / 12 = 0.00625

Find the number of payment periods: 8 years * 12 months/year = 96

Calculate the monthly payment using the amortization formula:

Payment = Loan Amount * (Interest Rate / (1 - (1 + Interest Rate)^(-Number of Payments)))

Payment = $6,200 * (0.00625 / (1 - (1 + 0.00625)^(-96)))

Payment = $79.88

So, the monthly payment on the loan is $79.88.

Calculate the total interest paid over the term of the loan:

Total Interest = (Monthly Payment * Number of Payments) - Loan Amount

Total Interest = ($79.88 * 96) - $6,200

Total Interest = $7,538.88

So, the total interest that will be paid during the term of the loan is $7,538.88.
