Find value of x .

Value of the manuscript is as follows

A. The value of the manuscript 5 years ago is $250.

B. The value of the manuscript now is $10,000.

Appreciation is an increase in the value of an asset over time. This is unlike depreciation, which lowers an asset's value over its useful life. The appreciation rate is the rate at which an asset grows in value.

% increase=(new price - original price) / original price

8.0= 2000/original price

8*original price = 2000

original price = $250

So the value of the manuscript 5 years ago is $250.

Increase is 2000 , 5 times that.

new price is $10,000

The value of the manuscript now is $10,000.

Hence , the manuscript has the following value:

A. The manuscript was worth $250 five years ago.

B. The manuscript is currently worth $10,000.

Also, we need to underline the variable part of each term.

We know that,  variable is a term which represents an unknown value or quantity.

We have been given an quadratic expression.

5 - 8n - 3n²

We can observe that, 5, -8, -3 are fixed numbers i.e., constants.

And the alphabet n can take any real value.

Consider the first term,

5 => it is a constant

Consider the second term,

- 8n => here, the variable is n

Consider the third term,

Answer:

C(x) = 20x + 120

Step-by-step explanation:

(a). If x=5 (you replace x with 5)

C(5) = 20(5) + 120

= 100+120=$220

Cost of producing five items is $220

(b). if x=16

C(16) = 20(16) + 120

= 320 + 120 = $440

Cost of producing sixteen items is $440

(c). C(35) = 820

This means that the cost of producing 35 items is $820

Answer:

1000

Step-by-step explanation:

The equation is,

→ 34.624 × x = 34624

Solving for the value of x,

→ 34.624 × x = 34624

→ x = 34624/34.624

→ [ x = 1000 ]

Thus, value of x is 1000.

I suppose you mean

[tex]f(x) f(y) = f(x + y) + f(x - y)[/tex]

Let [tex]x=1[/tex] and [tex]y=0[/tex]. Then

[tex]f(1) f(0) = f(1 + 0) + f(1 - 0) \implies f(1) f(0) = 2 f(1) \implies f(0) = 2[/tex]

Now if we fix [tex]y=1[/tex], the functional equation reduces to the recurrence relation

[tex]f(x) f(1) = f(x + 1) + f(x - 1) \implies f(x+1) - 3f(x) + f(x-1) = 0[/tex]

and we can find [tex]f(7)[/tex] with a few rounds of substitution.

[tex]x=1 \implies f(2) - 3f(1) + f(0) = 0 \implies f(2) = 3f(1) - f(0) = 7[/tex]

[tex]x=2 \implies f(3) - 3f(2) + f(1) = 0 \implies f(3) = 3f(2) - f(1) = 18[/tex]

[tex]x=3 \implies f(4) - 3f(3) + f(2) = 0 \implies f(4) = 3f(3) - f(2) = 47[/tex]

[tex]x=4 \implies f(5) - 3f(4) + f(3) = 0 \implies f(5) = 3f(4) - f(3) = 123[/tex]

[tex]x=5 \implies f(6) - 3f(5) + f(4) = 0 \implies f(6) = 3f(5) - f(4) = 322[/tex]

[tex]x=6 \implies f(7) - 3f(6) + f(5) = 0 \implies f(7) = 3f(6) - f(5) = \boxed{843}[/tex]

Step-by-step explanation:

2y-1/y x (y+4 - y-2/y x (y +4 ) - 2(y + 4)

2y -1 / y x (y+4) - y-2/(y+4) x (y-2)

2y-1/y x (y+4) - 1/y +4

2y -1 -y/y x (y + 4)

y-1/y^2 +4y

Answer:

[tex]\dfrac{y-1}{y(y+4)}[/tex]

Step-by-step explanation:

Given expression:

[tex]\implies \dfrac{2y-1}{y^2+4y}-\dfrac{y-2}{y^2+2y-8}[/tex]

Factor the denominators of both fractions:

[tex]\implies \dfrac{2y-1}{y(y+4)}-\dfrac{y-2}{y^2+4y-2y-8}[/tex]

[tex]\implies \dfrac{2y-1}{y(y+4)}-\dfrac{y-2}{y(y+4)-2(y+4)}[/tex]

[tex]\implies \dfrac{2y-1}{y(y+4)}-\dfrac{y-2}{(y-2)(y+4)}[/tex]

Cancel the common factor (y - 2) of the right fraction:

[tex]\implies \dfrac{2y-1}{y(y+4)}-\dfrac{1}{(y+4)}[/tex]

Adjust the fractions based on the LCM of y(y + 4):

[tex]\implies \dfrac{2y-1}{y(y+4)}-\dfrac{y}{y(y+4)}[/tex]

[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}-\dfrac{b}{c}=\dfrac{a-b}{c}:[/tex]

[tex]\implies \dfrac{2y-1-y}{y(y+4)}[/tex]

Simplify:

[tex]\implies \dfrac{y-1}{y(y+4)}[/tex]

The linear equation that passes through (10, 6) and (30, 12) is:

y = (3/10)*x + 3

Remember that the general line equation (in the slope-intercept form) is:

y = a*x + b

Where a is the slope and b is the y-axis intercept.

If the line passes through two points (x₁, y₁) and (x₂, y₂), the slope will be:

a = (y₂ - y₁)/(x₂ - x₁)

Then in this case the slope is:

a  = (12 - 6)/(30 - 10) = 6/20 = 3/10

Replacing that in our line we get:

y = (3/10)*x + b

To find the value of b we replace the values of one of the points, i will use (10, 6), it gives:

6 = (3/10)*10 + b

6 = 3 + b

6 - 3 = b = 3

Then we conclude that the linear equation is:

y = (3/10)*x + 3

In mathematics, the derivative is the rate of variation of a function given respect to a variable. Derivatives are essential for solving calculus related differential equation issues.

The derivative is defined as the slope of a straight line that is tangent towards the curve at a certain location. An additional derivative definition is the limit of the function's instantaneous rate of evolution as the time between observations approaches zero. activity, such as currency and interest rate risk, for a set length of time.

By removing the taxes from the gross pay, we can see that Carlos' net pay is 1,320.30 dollars.

To get Carlos' net pay, we need to take his gross pay, which is $1,800.00 and subtract all the taxes shown here.

The taxes (in percentage) are:

The total percentage in these taxes is 19% + 6.2% = 25.2%

Then a 25.2% of the gross pay will be gone in taxes, then we need to subtract:

0.252* $1,800.00 = $453.60

We also need to subtract the $26.10 for Medicare, then we will get that Carlos' net pay is given by the expression:

$1,800.00 - $26.10 - $453.60 = $1,320.30
