I think it would be 132

Step-by-step explanation:

20% of 110=22 (22+110)=132

Approximately 114.29% of the growth came from higher productivity.

To determine the percent of growth that came from higher productivity, we need to compare the change in output (Y) with the change in inputs (K and L). Here's how we can calculate it:

In the first year:

Initial output (Y₁) = 18

Initial inputs (K₁, L₁) = (4, 9)

In the second year:

Final output (Y₂) = 26

Final inputs (K₂, L₂) = (4, 16)

Change in output = Y₂ - Y₁ = 26 - 18 = 8

Change in inputs = (K₂ + L₂) - (K₁ + L₁) = (4 + 16) - (4 + 9) = 7

Now, let's calculate the percent of growth that came from higher productivity:

Percent of growth from higher productivity = (Change in output / Change in inputs) * 100

= (8 / 7) * 100 ≈ 114.29

Therefore, approximately 114.29% of the growth came from higher productivity.

What is continuous compounding?

There is no cap on how frequently interest can compound thanks to continuous compounding. A balance can compound continuously an infinite number of times, which means interest is earned on it constantly.

Given:

Lira will not make any further investments in the withdrawals from the account until it is worth $10000.

Suppose that the interest rate for the account is 8.0% , compounded continuously.

We have to find the amount in the account after 20 years.

Consider, the compounded continuously formula

\(P(t)= P_0e^r^t\)

Where

P(t) = Value at time t.

\(P_0\) = Original principle sum = $10,000

r = Interest rate = 8.0% = 0.08

t = time in years = 20

Plug the values in the above formula

\(P(t) = 10000e^0^.^0^8^*^2^0\\P(t) = 49530.32\)

Hence, the amount in the account after 20 years is $49530.32.

The probability that someone does not believe that it is morally wrong to not report all income on tax returns is = 0.15

For given question,

A research center poll showed that 85 percent of people believe that it is morally wrong to not report all income on tax returns.

Thus, there are 18 ways to choose one book, 153 ways to choose two books, and 360 ways to choose three books, one from each category.

To find the number of ways a student can choose from the given library, we need to use the formula for combinations.

The formula for combinations is:
nCr = n! / r!(n-r)!

where n is the total number of items, r is the number of items to be chosen, and ! denotes factorial.

Let's consider the different ways a student can choose:

1. Choosing one book from any category:
Total number of books = 5+3+6+4 = 18
n = 18, r = 1
Number of ways = 18C1 = 18! / 1!(18-1)! = 18

2. Choosing two books from any category:
n = 18, r = 2
Number of ways = 18C2 = 18! / 2!(18-2)! = 153

3. Choosing three books, one from each category:
For this, we need to choose one book from each category, and the order of selection does not matter.
n1 = 5, r1 = 1 (for history)
n2 = 3, r2 = 1 (for sociology)
n3 = 6, r3 = 1 (for anthropology)
n4 = 4, r4 = 1 (for psychology)
Number of ways = (5C1 x 3C1 x 6C1 x 4C1) = (5 x 3 x 6 x 4) = 360

Therefore, there are 18 ways to choose one book, 153 ways to choose two books, and 360 ways to choose three books, one from each category.

The standard form of the equation of the quadratic function is y = -1/8x^2 + 1/4x - 41/8

From the question, we have the following parameters that can be used in our computation:

(h, k) = (1, -5)

(x, y) = (5, -7)

A quadratic function is represented as

y = a(x - h)^2 + k

So, we have

y = a(x - 1)^2 - 5

Given that

(x, y) = (5, -7)

We have

-7 = a(5 - 1)^2 - 5

This gives

16a = -2

So, we have

a = -1/8

Recall that

y = a(x - 1)^2 - 5

So, we have

y = -1/8(x - 1)^2 - 5

Expand

y = -1/8(x^2 - 2x + 1) - 5

This gives

y = -1/8x^2 + 1/4x - 41/8

Mr. Morgan has to pay a state tax of $ 38.4 in a biweekly basis on his $42000 yearly income.

State income taxes are a proportion of your income that you pay to the state government based on how much money you earn from your work, and they vary from state to state.

Tax exemption is the reduction or elimination of a requirement to make a required payment that would otherwise be imposed on individuals, properties, income, or transactions by a ruling power. Tax-exempt status might offer full tax exemption, reduced rates, or tax on only some things.

The more children you have, the more taxes you pay since children are exemptions or deductions on tax forms. Some non-profit organizations are tax-exempt, which means they don't have to pay any taxes. People are also exempt from participating in certain vocations and battles. You are excused if you have an exemption.

Personal Exemption is non taxable = $ 3600

Total income = $ 42000 yearly

Total taxable income = 42000 - 3600 = $ 38400

Total tax yearly = 2.6 % of 38400 = (2.6/100)*38400 = $ 998.4

Total tax generated biweekly is = (998.4/52)*2 = $ 38.4

(a) To find the derivative of y with respect to x, we can use the chain rule.

First, we'll find dy/dt:

dy/dt = d/dt(4t^2 - t^3) = 8t - 3t^2

Next, we'll find dx/dt:

dx/dt = d/dt(3t) = 3

To find dy/dx, we divide dy/dt by dx/dt:

dy/dx = (dy/dt)/(dx/dt) = (8t - 3t^2) / 3

(b) To find the equation of the tangent to the curve at the point where t = 2, we substitute t = 2 into the parametric equations:

x(2) = 3(2) = 6

y(2) = 4(2^2) - 2^3 = 8 - 8 = 0

So the point of tangency is (6, 0). We can use the derivative dy/dx from part (a) to find the slope of the tangent line at this point:

dy/dx = (8t - 3t^2) / 3

dy/dx = (8(2) - 3(2^2)) / 3

dy/dx = (16 - 12) / 3

dy/dx = 4 / 3

The slope of the tangent line is 4/3. Using the point-slope form of the equation of a line, we can write the equation of the tangent as:

y - 0 = (4/3)(x - 6)

y = (4/3)x - 8

The solution to the given differential equation 2xy(dy/dx) = y², with the initial condition y(2) = 3, is y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\).

To solve the given differential equation

2xy(dy/dx) = y²

We will use separation of variables and integrate to find the solution.

Start with the given equation

2xy(dy/dx) = y²

Divide both sides by y²:

(2x/y) dy = dx

Integrate both sides:

∫(2x/y) dy = ∫dx

Integrating the left side requires a substitution. Let u = y², then du = 2y dy:

∫(2x/u) du = ∫dx

2∫(x/u) du = ∫dx

2 ln|u| = x + C

Replacing u with y²:

2 ln|y²| = x + C

Using the properties of logarithms:

ln|y⁴| = x + C

Exponentiating both sides:

|y⁴| = \(e^{x + C}\)

Since the absolute value is taken, we can remove it and incorporate the constant of integration

y⁴ = \(e^{x + C}\)

Simplifying, let A = \(e^C:\)

y^4 = A * eˣ

Taking the fourth root of both sides:

y = (A * eˣ\()^{1/4}\)

Now we can incorporate the initial condition y(2) = 3

3 = (A * e²\()^{1/4}\)

Cubing both sides:

27 = A * e²

Solving for A:

A = 27 / e²

Finally, substituting A back into the solution

y = ((27 / e²) * eˣ\()^{1/4}\)

Simplifying further

y = (27 *  e⁽ˣ⁻²⁾\()^{1/4}\)

Therefore, the solution to the given differential equation with the initial condition y(2) = 3 is

y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\)

Solution:

Let \(x\) be the input value.

The square of the input is \(x^2\).

Doubles the square of the input \(2x^2\).

Doubles the square of the input and then subtracts 13, i.e., \(2x^2-13\).

So, the function is:

\(g(x)=2x^2-13\)

Putting \(x=3\) in the above function, we get

\(g(3)=2(9)-13\)

\(g(3)=18-13\)

\(g(3)=5\)

Therefore, the value of \(g(3)\) is 5.

Step-by-step explanation:

Hey There!

So the congruency statement ABC = TUV

states that side AB = side TU side BC  = side UV and side CA = side VT

The given side lengths are BC and UV which are congruent to each other so we set up an equation to solve for x

7x+2=6x+11

step 1 subtract 2 from each side

2-2 cancels out

11-2=9

Now we have

7x=6x+9

step 2

subtract 6x from each side

7x-6x=x

6x-6x cancels out

now we have 9=x so x=9

Now we just plug in 9 to x in (6x+11)

to find the length of the given side length

6x9=54

54+11=65

Because side VU and side BC are congruent they both equal 65 cm

So we can conclude that the length of the given sides is 65 cm

The measure of the line segment AB is  36cm .

In the question ,

it is given that ,

The triangle ABC is a isosceles triangle ,

that means side AB = side BC ,

and the length of base AC = 24 cm .

given the perimeter of the triangle is 96 cm .

So ,
