Eight less than a number doubled is twenty more than the number. What is the number?

Answers

Let the number be a ....=>Number doubled : 2a ..=>Eight less than the no. Doubled : 2a - 8=>Eight less than the no. doubled is 20 more than the no. : 2a - 8 = 20 + a=>2a - 8 - 20 - a = 0=>2a -a - 20 -8 = 0=>a -28 = 0=>a = 28=>so the number is 28...Hope it helps!!!

Express Fx and Fy in terms of the length of the vector F and the angle θ, with the components separated by a comma.

Answers

Fx, Fy = F cos θ, F sin θ

Further explanation

This is a fundamental problem with vector components.

A vector quantity is some quantities that have the magnitude and a direction. For example, all forces or momentums are vectors.
Whereas, a scalar quantity only has magnitude. For example, all forms of energy are scalars.

The list below shows some recognized methods to represent a vector. i.e., a force.

$\boxed{ \ \textit{\textbf{F}}, \vec{F}, \bar{F} \ }$

It is possible to split one vector into two vectors. This process is called resolving and the vectors that we get are called the components of the original vector.

Vector problems can always be solved by using the mathematics of trigonometry, i.e., the functions of sine or cosine. This is particularly appropriate when resolving.

By using the cartesian coordinate system, see the attachment on how to calculate the values of either these components.

Horizontal component: $\boxed{ \ F_x = \textit{\textbf{F}}\ cos \ \theta \ }$
Vertical component: $\boxed{ \ F_y = \textit{\textbf{F}} \ sin \ \theta \ }$

Here, the angle between the vector F and the horizontal axis we call θ (theta).

As a reminder:

$\boxed{cos \ \theta = (adjacent)/(hypotenuse)} \rightarrow cos \ \theta = (F_x)/(F) \rightarrow \boxed{F_x = F cos \ \theta}$
$\boxed{sin \ \theta = (opposite)/(hypotenuse)} \rightarrow sin \ \theta = (F_y)/(F) \rightarrow \boxed{F_y = F sin \ \theta}$

Keywords: express Fx and Fy, in terms of the length of the vector F, and the angle θ, with the components, separated by a comma, resolving, split, horizontal, vertical, angle, theta, sine, cosine, trigonometry, cartesian coordinate system

The components of the vector F are $\fbox{\begin\nF\cos\theta\end{minispace}}$ and $\fbox{\begin\nF\sin\theta\end{minispace}}$ .

Further Explanation:

A physical quantity can be defined as the physical property that can be measured and have some value in numbers.

For example- mass, amount of substance, length, time, electric current, temperature, force, light intensity, density, velocity, speed etc.

A quantity is said as a vector if it has some magnitude and direction in order to give the details regarding the quantity.

For example- Force, velocity, current density, electric field, magnetic field, displacement, acceleration, momentum etc.

A quantity is said as a scalar if it has only the magnitude in order to give the details regarding the quantity.

For example- speed, distance, current, volume, density, mass, energy, time, temperature etc.

Given:

The resultant vector is $F$ .

The horizontal component is ${\vec F_x}$ .

The vertical component is ${\vec F_y}$ .

Concept:

Let a vector have some length $F$ and making an angle $\theta$ with horizontal axis.

The triangle rule of resultant vector state that when two vector is denoted by the two sides of the triangle and the magnitude and the direction is taken in the same direction then the third side of the triangle denoted by resultant vector with some magnitude and direction.

The diagram is drawn as shown in the Figure 1.

The vertical component is along y-axis and the vertical component of the vector $\vec F$ is expressed as:

${\vec F_y}=F\sin\theta$

The horizontal component is along x-axis and the horizontal component of the vector $\vec F$ is expressed as:

${\vec F_x}=F\cos\theta$

therefore, the components of the vector F are $\fbox{\begin\nF\cos\theta\end{minispace}}$ and $\fbox{\begin\nF\sin\theta\end{minispace}}$ .

What are the zeros of the polynomial function f(x) = x3 - 2x2 - 24x?

Answers

The zeroes of the polynomial function are 0, 6, and -4.

Given that,

Polynomial function; $\rm f(x) = x^3-2x^2-24x$ .

We have to determine,

The zeroes of the polynomial,

According to the question,

To determine the zeroes of the given polynomial function following all the steps given below.

Polynomial function; $\rm f(x) = x^3-2x^2-24x$ .

Factorize the polynomial function to find the zeroes of the function,

$\rm x^3-2x^2-24x =0\n\n\rm x(x^2-2x-24)=0\n\nx(x^2-6x+4x-24)=0\n\nx(x(x-6)+4(x-6))=0\n\nx ( (x-6) (x+4)) =0\n\nx (x-6) (x+4) =0$

Therefore,

The zeroes of the polynomial function are,

$\rm x = 0\n\nx - 6 =0, \ \ x =6\n\nx +4 =0, \ \ x = -4$

Hence, The zeroes of the polynomial function are 0, 6, and -4.

Making Consumer ChoicesI. The Bread Machine (25 points)r /> In real life, you must often make choices about whether to buy something pre-made or make it yourself. There are many things to consider: quality of homemade vs. bought, expense, convenience, enjoyment of making something, etc. In this response, you will be looking at the choice of buying a bread machine or relying exclusively on store bought bread.

A. The bread machine you are interested in costs $100 with tax.
The ingredients to make one loaf of bread cost $0.80.
What is the rate of cost of one loaf of bread?

B. What is your start up cost? (cost of machine)

C. Write a linear equation, y = mx + b for the total cost.

D. Graph the equation on the graph provided. You may use either Point Plotting or Slope-Intercept. Be sure to locate at least 3 points. You may want to do this in pencil in case you decide to use more points later in the problem.

Answers

cool question relying on real life scinarios

A.

1 loaf=inital cost for macine+cost per bread or
number of loaves=x
cost to make=y
y=100+0.8x
so to find 1 loaf, just subsitute 1 for x
y=100+.8(1)
y=100+0.8
y=100.80
1 loaf costs $100.80 to make

B.
start up cost is $100

C. linear equation is
start up cost+cost per loaf times loaf or
y=100+0.8x
in y=mx+b form
y=0.8x+100

C.
to find points, just subsitute values for x and get values for y (I used multiplules of 10 so that you wouldn't have to plot a decimal coordinate)

if we put it 0 for x, we get 100 for y
if we put in 10 for x, we get 108 for y
if we put in 20 for x, we get 116 for y
and of course don't use negative becasue you can't make negative amounts of bread

Express (x-1)^2
as a trinomial in standard form.

Answers

Final answer:

To express (x-1)^2 as a trinomial in standard form, we expand the square using the formula (a-b)^2 = a^2 - 2ab + b^2. Substituting a = x and b = 1, we get x^2 - 2x + 1.

Explanation:

To express the expression (x-1)^2 as a trinomial in standard form, we need to apply the square of a binomial formula, which is (a - b)^2 = a^2 - 2ab + b^2. In this case, a is x, and b is 1. Substituting these values into the formula, we get:

(x - 1)^2 = x^2 - 2(x)(1) + 1^2

Now, simplify each term:

1. x^2 represents the square of the first term, which is x.

2. 2(x)(1) = 2x, representing twice the product of x and 1.

3. 1^2 = 1, which is the square of the second term, 1.

So, when we simplify the expression further, we have:

(x - 1)^2 = x^2 - 2x + 1

This is the trinomial representation of (x-1)^2 in standard form. It consists of three terms: x^2, -2x, and 1, with each term having a specific coefficient.
