Step-by-step explanation:

x = earnings from the store

y = earnings from the college

x + y = 67,250

x = 3y + 1,250

now we use the identity of the second equation in the first equation :

(3y + 1,250) + y = 67,250

4y = 66,000

y = $16,500

x = 3y + 1,250 = 3×16,500 + 1,250 = 49,500 + 1,250 =

= $50,750

It comes from integrating by parts twice. Let

[tex]I = \displaystyle \int e^n \sin(\pi n) \, dn[/tex]

Recall the IBP formula,

[tex]\displaystyle \int u \, dv = uv - \int v \, du[/tex]

Let

[tex]u = \sin(\pi n) \implies du = \pi \cos(\pi n) \, dn[/tex]

[tex]dv = e^n \, dn \implies v = e^n[/tex]

Then

[tex]\displaystyle I = e^n \sin(\pi n) - \pi \int e^n \cos(\pi n) \, dn[/tex]

Apply IBP once more, with

[tex]u = \cos(\pi n) \implies du = -\pi \sin(\pi n) \, dn[/tex]

[tex]dv = e^n \, dn \implies v = e^n[/tex]

Notice that the ∫ v du term contains the original integral, so that

[tex]\displaystyle I = e^n \sin(\pi n) - \pi \left(e^n \cos(\pi n) + \pi \int e^n \sin(\pi n) \, dn\right)[/tex]

[tex]\displaystyle I = \left(\sin(\pi n) - \pi \cos(\pi n)\right) e^n - \pi^2 I[/tex]

[tex]\displaystyle (1 + \pi^2) I = \left(\sin(\pi n) - \pi \cos(\pi n)\right) e^n[/tex]

[tex]\implies \displaystyle I = \frac{\left(\sin(\pi n) - \pi \cos(\pi n)\right) e^n}{1+\pi^2} + C[/tex]

The recursive function that gives the number of books Ashley has at any time is f(t) = f(t-1) - n where f(0) =100

The given parameters are:

Initial = 100

Rate per week, r = n

The initial number of books means that:

f(0) = 100

The rate of n means that Ashley has n less books each week.

So, we have:

f(t) = f(t-1) - n

Where t represents the number of weeks

Hence, the recursive function that gives the number of books Ashley has at any time is f(t) = f(t-1) - n where f(0) =100

Step-by-step explanation:

when i text my boy he is ute

Answer:

Shirt + tie = $ 58

shirth = 30 more than that of tie

let the price of tie be X

therefore the price of shirt = 30 + X

30 + X + X = 58

30 + 2x = 58

2x = 58 - 30

Based on the expenses involved in running the property, and the rental amount, the return on the investment would be 31.1%.

First find the amount earned per year:

= 850 x 12

= $10,200

The yearly expenses would be:

= (390 x 12) + (60 x 12) + (340 x 2) + 500 + (100 x 12)

= 4,680 + 720 + 680 + 500 + 1,200

= $7,780

The annual ROI is:

= (10,200 - 7,780) / 10,200 x 100%

= 31.1%

From the question given above, the ratio of L : W in simplified form is given as: 6 : 5. See the explanation below.

A ratio, simply, can be defined as the quantitative relationship that exists between two values which is indicative of the number of times one value can be obtained from the other.

Let X be the width of one of the rectangles and let its height be Y.

It is clear from the image that:

4X = 3Y

Hence

(4/3)X  = Y

Therefore,

Lenght (L) = 3Y

= 3 (4/3)X

= 4X

Width (W) = Y + 2X

= (4/3)X + 2X

= (10/3)X

Therefore,

L : W =  4X: 10/3X

= 4:10/3

To remove the fraction, multiply both sides of the ratio by 3

= 12 : 10, furhter simplify by halving each value, and we have

= 6:5

Hence, the ratio L: W in simplified form is 6 : 5.

Step-by-step explanation:

To solve this we take the total cost divided by the total number of chicken wings to get $2.10.

Hope that helps! :)

Answer:

1 wing = $2.10

Step-by-step explanation:

11 wings = $23.10

Let 1 wing = x

11x = 23.10

To solve for x, we divide both sides by 11 :

11x÷ 11 = 23.10 ÷11

x = 2.1

So 1 wing = $2.10

Step-by-step explanation:

Givens

Area = 160 sqr inches

width = x

length = x + 6

Equation

Area = L * w

Solution

Substitute in the equation all of the givens.

160 = x(x + 6)                     Remove the brackets

160 = x^2 + 6x                   Subtract 160 from both sides.

160-160 = x^2 + 6x - 160

0 = x^2 + 6x - 160

This equation factors. Turn it around first

x^2 + 6x - 160 =  0

(x - 10)(x + 16) = 0

Answer

x (width) = 10

x + 16 = 16

The length is 16 inches and the width is 10 inches.

Answer:

How do you calculate after tax rate of return?

After-tax return on investment is the net return to the investor after ordinary income and capital gains taxes are subtracted. This is calculated as: After-tax return on investment = ((P1 - Po) (1 - Tc) / Po) + C1(1 - To) / Po.

How do you calculate before tax return?

The pre-tax rate of return is calculated as the after-tax rate of return divided by one, minus the tax rate. For example, suppose a person obtains a 4.25% reporting rate for ABC shares and is subject to a 15% income tax. Therefore, the pre-tax rate of return is 5% or 4.25%/(1 - 15%).

How do you calculate real rate of return after tax and inflation?

To calculate the real rate of return after tax, divide 1 plus the after-tax return by 1 plus the inflation rate. Dividing by inflation reflects the fact a dollar in hand today is worth more than a dollar in hand tomorrow. In other words, future dollars have less purchasing power than today's dollars.
