Step-by-step explanation:

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.

Answer:

     the value of h(4) is 36 from given equation.

Step-by-step explanation:

Given that

        h(x) = x³ - 2x² + x

To find

So, according the question

We have,

        h(x) = x³ - 2x² + x

For finding the value of h(4) from the given polynomial equation, we have to replace x from 4 or in other word we have to put x = 4 in given polynomial equation.

So, let's put x = 4 in that equation.

We get,

        h(4) = (4)³ - 2(4)² + 4

               = 64 - 2×16 + 4

               = 68 - 32

        h(4) = 36  

Answer: Hance the value of h(4) is 36 from given equation.

Answer:

AM= 2x+4

MB= 5x-8

AB= ?

So to get AB, you would need to find the total measurements of AM and MB.

AM=MB

2x+4=5x-8

2x=5x-12

-3x=-12

x=4

So now to find the measurement of AB, you need to plug it into AM and MB.

2(4)+4+5(4)-8= 24!!!

So the measure of AB would be 24.

The function, after the transformations is y'' = 1/4(x +84)

The function equation is given as:

y = |x|

1) Reflect the function about the y-axis.

This is represented as

(x, y) = (-x, y)

So, we have:

y' = |-x|

This gives

y' = |x|

This is represented as

(x, y) = (x, 1/4y)

So, we have:

y'' = 1/4y'

This gives

y'' = 1/4|x|

This is represented as

(x, y) = (x + 84, y)

So, we have:

y'' = 1/4(x +84)

Hence, the function, after the transformations is y'' = 1/4(x +84)

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

We conclude that, after taxes and that, Carlos' net pay is 1,320.30 dollars.

The solution to the system of the equations h = (1/2)t + 4 and h = (1/4)t + 5.5 will be 7 cm and 6 weeks.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Half a centimeter grows on a 4 cm bean plant per week. One-fourth of a centimeter is added to a 5.5 cm bloom per week.

Let h be the height of the plant and t be the number of weeks. Then the equations will be

h = (1/2)t + 4

h = (1/4)t + 5.5

The solution to the equations will be

(1/2)t + 4 = (1/4)t + 5.5

(1/2 - 1/4)t = 5.5 - 4

t / 4 = 1.5

t = 6

Then the height of the plant will be

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

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.

The values of the two unknowns x and y are 8 and 32 respectively.

Here, we are given the following set of ratios-

21x, 1/4, y/8

These ratios are all equivalent, this implies-

2/x = 1/4 = y/8

Let us take the first two ratios-

2/x = 1/4

cross multiplying the two we get

2 x 4 = x

8 = x

x = 8

We've found the value of x

Now, let us take the other two ratios-

1/4 = y/8
