They are exempt from income tax and we would get the income tax withheld as $340.

What is tax?

The person does not have another source of income, and there are no exceptions that are claimed by the person.

The withheld tax which is held every week can be calculated as;

Amount of income tax = 30 % of 1,166

Amount of income tax = $339.6

Amount of income tax = $340

Hence, they are exempt from income tax and we would get the income tax withheld as $340.

Answers

The volume of the cone and pyramid are the same.

Formula for volume of cone = ⅓(144π × h)

What is the Volume of a Triangular Pyramid and a Cone?

Volume of cone = ⅓[πr² × height of cone)

Volume of triangular pyramid = ⅓[(½bh × height of pyramid)]

Also note the following:

Area of a circle = πr²

Area of a triangle = ½bh

Part A:

Area of circle 1 = πr² = π(12²) = 144π units²

Area of circle 2 = πr² = π(6²) = 36π units²

Area of circle 3 = πr² = π(3²) = 9π units²

Area of triangle 1 = ½(24)(12π) = 144π units²

Area of triangle 2 = ½(12)(6π) = 36π units²

Area of triangle 3 = ½(6)(3π) = 9π units²

Part B: Based on our results in part A, the volumes of the cone and pyramid, having the same height are the same.

Part C:

Volume of pyramid = ⅓(144π × h)

Using this measurement and our conclusion in part B:

The difference between the amount of money that Gabriel receives and the amount of

Work out the amount of money that Danil receives.

Answers

Answer:

Danil received 147 euros

Step-by-step explanation:

Let, Danil,Gabriel and Hardly share some money of 3x:5x:9x ratio then,

From the question,

9x - 5x= 196

or, 4x= 196

or, x = 196/4

or, x = 49 euros

Again,Danil received 3x share of money

=3*49

=147 euros

Answer:

Step-by-step explanation:

Ratio = 3 : 5 : 9

Money received by  Danil = 3x  

Money received by Gabriel = 5x

Money received by Hadley = 9x

Difference in the amount between Gabriel and Hadley = 196 euros

9x - 5x = 196

       4x = 196

         x = 196/4

        x = 49

Money received by Danil = 3*49

Answers

Answer:

The answer is 20

Step-by-step explanation:

There's two ways in which you can do this. The first one, and the simpliest one is finding the derivative of the equation P(x). After finding the derivative, set the dy/dx to be zero (so set the derivative to be zero). Then solve for x. This should give you the point at which there's no increase or decrease in the value of P, thus meaning the point at which its the maximum.

3. The curve C with equation y=f(x) is such that, dy/dx = 3x^2 + 4x +k
Where k is a constant.
Given that passes through the points (0, -2) and (2, 18).
a. Show that k = 2 and find an equation for C
b. Show that the line with equation y = x-2 is a tangent to C and find the coordinates of the point of contact.​

Answers

a. Given that y = f(x) and f(0) = -2, by the fundamental theorem of calculus we have

[tex]\displaystyle \frac{dy}{dx} = 3x^2 + 4x + k \implies y = f(0) + \int_0^x (3t^2+4t+k) \, dt[/tex]

Evaluate the integral to solve for y :

[tex]\displaystyle y = -2 + \int_0^x (3t^2+4t+k) \, dt[/tex]

[tex]\displaystyle y = -2 + (t^3+2t^2+kt)\bigg|_0^x[/tex]

[tex]\displaystyle y = x^3+2x^2+kx - 2[/tex]

Use the other known value, f(2) = 18, to solve for k :

[tex]18 = 2^3 + 2\times2^2+2k - 2 \implies \boxed{k = 2}[/tex]

Then the curve C has equation

[tex]\boxed{y = x^3 + 2x^2 + 2x - 2}[/tex]

b. Any tangent to the curve C at a point (a, f(a)) has slope equal to the derivative of y at that point:

[tex]\dfrac{dy}{dx}\bigg|_{x=a} = 3a^2 + 4a + 2[/tex]

The slope of the given tangent line [tex]y=x-2[/tex] is 1. Solve for a :

[tex]3a^2 + 4a + 2 = 1 \implies 3a^2 + 4a + 1 = (3a+1)(a+1)=0 \implies a = -\dfrac13 \text{ or }a = -1[/tex]

so we know there exists a tangent to C with slope 1. When x = -1/3, we have y = f(-1/3) = -67/27; when x = -1, we have y = f(-1) = -3. This means the tangent line must meet C at either (-1/3, -67/27) or (-1, -3).

Decide which of these points is correct:

[tex]x - 2 = x^3 + 2x^2 + 2x - 2 \implies x^3 + 2x^2 + x = x(x+1)^2=0 \implies x=0 \text{ or } x = -1[/tex]

So, the point of contact between the tangent line and C is (-1, -3).

The inequality of the expression is a greater than inequality, and the required inequality is 2x + y > 34

How to determine the inequality?

From the question, we have the following representations:

x represents field goalsy represents foul shots

A field goal has 2 points, while a foul shot has 1 point.

So, the number of points in a game is:

Score = 2x + y

The team is behind by 34 points.

So, the team must attain above 34 points

This means that the score must be greater than 34.

What is Surface Area?

Surface area is simply the amount of space covering the outside of a 3-dimensional object.

The surface area of a rectangular prism is expressed;

A = 2( wl + hl + hw )

Given the data in the question;

Height of the rectangular prism h = 18inWidth w = 16inLength l = 20inSurface area of the rectangular prism A = ?

To determine the least amount of wrapping paper that Amy needs to wrap the present in the shape of a rectangular prism, we substitute our given values into the expression above.

A = 2( wl + hl + hw )

A = 2( (16in×20in) + (18in×20in) + (18in×16in) )

A = 2( 320in² + 360in² + 288in² )

A = 2( 968in² )

A = 1936in²
