The Bells are adding a new room to their house. The room will be a cube with a volume of 4096 ft^3. They are going to put in hardwood floors, and the contractor charges $10 per square foot. How much will the hardwood floors cost?

### Answers

The cost for the hardware floors will be 2560$

The bells are adding a new room to their house .

Volume of the room is 4096ft³.

Let one side of the room is x

We well know that

The volume of the cube is x³

And x³=4096ft³

So , one side of the room

x =√4096

x=16 ft

And we have to find the area of the floor that becomes a square.

Area of a square is x².

If x=16

x²=16²

x²=256ft²

This is the area of floor of room.

And the cost of hardware floor is 10$/ft²

Now we have to find the total cost of hardware floor for room.

Total Cost of floor = area of floor × cost /ft

Total cost of floor= 256×10

Total cost of floor= 2560$.

If you have the x and y components of a vector, which trigonometry function can you use to determine its angle relative to the x-axis?.

### Answers

If we have the x and y components of a **vector**, the **trigonometry function** that can be used to determine its angle relative to the x-axis is **cosine **function.

For given question,

Let α be an angle between **vector **a and **vector **b.

The **angles **between two **vectors **is given by,

cos(α) = [tex]\frac{\vec a . \vec b}{|\vec a | | \vec b|}[/tex]

The x **component **of **vector **is usually denoted by [tex]\vec i[/tex]

Let **vector **be [tex]x\vec i + y\vec j[/tex]

Let [tex]\vec a=\vec i, ~ \vec b=x\vec i + y\vec j[/tex]

[tex]\vec a . \vec b=x[/tex]

[tex]|\vec a|=1[/tex]

[tex]|\vec b|=\sqrt{x^2+y^2}[/tex]

So, the **angle **between the **vector and x-axis** is [tex]cos^{-1}(\frac{x}{\sqrt{x^2+y^2} } )[/tex]

Therefore, if we have the x and y components of a **vector**, the **trigonometry function** that can be used to determine its angle relative to the x-axis is **cosine **function.

An object is moving at a speed of 63 centimeters every 2 days. Express this speed in meters per hour.Round your answer to the nearest hundredth.

### Answers

This **speed **in meters per hour is 0.01 meter per hour

How to determine the speed?

The given parameter is

Speed = 63 centimeters every 2 days

Divide 63 by 2

So, we have:

Speed = 31.5 centimeters every day

There are **24 hours **in a day

So, we have

Speed = 31.5 centimeters every 24 hours

100 cm equals 1 m

So, we have:

Speed = 0.315 meters every 24 hours

Verify that y=e^xy is an implicit solution of the differential equation (1-xy)y'=y^2

### Answers

**Yes,** y = e^xy is an **implicit solution **of the **differential equation**

Here,

The **differential equation** (1-xy)y' = y^2

And, y = e^xy is an** implicit solution** of the **differential equation **

**What is Differential equation?**

A differential equation is a mathematical equation that relates some function with its derivatives.

Now,

To show y = e^xy is an implicit solution of the differential equation

(1-xy)y'=y^2, we have to find the solution of differential equation.

The** differential equation** is;

[tex](1-xy)y'=y^2\\\\\\\\[/tex]

[tex](1-xy) \frac{dy}{dx} = y^2[/tex]

[tex]\frac{dx}{dy} + \frac{x}{y} = \frac{1}{y^{2} }[/tex]

It is form of [tex]\frac{dx}{dy} + Px = Qy[/tex],

Where, P is the function of y and Q is the function of x.

Hence, **Integrating factor** = [tex]e^{\int\limits {\frac{1}{y} } \, dy} = e^{lny} = y[/tex]

The solution is;

[tex]x y = \int\limits {\frac{1}{y^{2} }y } \, dy + c[/tex]

Triangle A prime B prime C prime has vertex A prime at 3 comma negative 2, vertex B prime at 4 comma negative 5, and vertex C prime at 7 comma negative 1.

### Answers

Answer:

Step-by-step explanation:

Any 1 of the following transformations will work. There are others that are also possible.

translation up 4 units, followed by rotation CCW by 90°.

rotation CCW by 90°, followed by translation left 4 units.

rotation CCW 90° about the center (-2, -2).

Step-by-step explanation:

The order of vertices ABC is clockwise, as is the order of vertices A'B'C'. Thus, if reflection is involved, there are two (or some other even number of) reflections.

The orientation of line CA is to the east. The orientation of line C'A' is to the north, so the figure has been rotated 90° CCW. In general, such rotation can be accomplished by a single transformation about a suitably chosen center. Here, we're told there is a sequence of transformations involved, so a single rotation is probably not of interest.

If we rotate the figure 90° CCW, we find it ends up 4 units east of the final position. So, one possible transformation is 90° CCW + translation left 4 units.

If we rotate the final figure 90° CW, we find it ends up 4 units north of the starting position. So, another possible transformation is translation up 4 units + rotation 90° CCW.

Of course, rotation 90° CCW in either case is the same as rotation 270° CW.

(PLEASE HELP!) A car travels 76 km due north and then 25 km due east.

(a) What is the cars current bearing from the starting point correct to the nearest degree?

(b) How far is the car from the starting point correct to the nearest km?

### Answers

**Answer:**

**Step-by-step explanation:**

Look at the File I attached. The Question says that a car travels 76 km north then 25 km east. Now think of this as the Right angled triangle I attached in the file.

a) Bearing from the staring point to the means the degrees of the part i marked with a question mark.

Now SOH CAH TOA

76 km is the ADJACENT

25 km is the OPPOSITE

and x is the HYPOTENUSE

We have the values of the ADJACENT and the OPPOSITE.

Now see which rule has both, It is TOA(tan rule) which is:

tan(y) = OPPOSITE/ADJACENT (y is the degrees we will get)

tan(y) = 25/76 ( opposite of the degree we need is 25 and adjacent is 76)

tan inverse(25/76) = y (inverse will be given as to the power -1 on the calculator)

FINAL ANSWER OF (a) = 18.21°

b) This part is asking for the length of the hypotenuse, which i denoted as x in the attached file.

For this part, you will use the Pythagoras Theorem

Which is :

a² + b² = c²

Where c is the hypotenuse and a and b are the opposite and adjacent.

So

76² + 25² = x²

6401 = x²

√6401 = x

x = 80.01

which of the relations represent y as a function of x

### Answers

For given relations, **relation **(1) and **relation **(3) represent y as a **function **of x.

And relation (2) does not represent y as a **function **of x.

In this question, we have been given some relations.

We need to determine which relations represent y as a **function **of x.

We know that a relation is **function **when there is unique **output **for each **input**.

Consider the first **relation**.

y = -3.4x

For each value of x there's unique and distinct output. Here x can take any real value.

so, the above relation is a **function**.

Consider the second relation.

We can observe that, for x = 1 there are two outputs i.e., y = 1 and y = -1.

Similarly for x = 4, there are two outputs y = 2 and y = -2.

this means, the second relation is not a **function**.

Now, consider the last relation.

From this graph we can see that from x = -∞ to x = ∞, there are unique outputs.

So, above graph represents a function.

Also, by **vertical line test**, the graph represents a function.

Therefore, for given relations, **relation **(1) and **relation **(3) represent y as a **function **of x.

And relation (2) does not represent y as a **function **of x.

y=9-x

y=2x^2+4x+6

### Answers

The **solution **of the given **equation **are (1/2 , 17/2) and (-3 , 12)

The two **equation** that we have been given are :

y = 9 – x (1)

y = 2x² + 4x + 6 (2)

We will solve this simultaneously, from equation (1) we will equate the value of y in equation (2) we get

9 – x = 2x² + 4x + 6

3 = 2x² + 5x

2x² + 5x – 3 = 0

Now to find the factors of the value x we will use **quadratic formula**.

x = (-b±√b² – 4ac)/2a

x = [ -5 ± √25 + 24 ]/4

x = [ -5 ± 7 ]/4

x = (-5 + 7)/4 and x = (-5 – 7)/4

x = 1/2 and x= -3

putting the required value of x in equation (1) we get

y = 9 – 1/2 and y = 9 – (-3)

y = 17/2 and y = 12

Hence the **solution** of the **equation **is (1/2 , 17/2) and (-3 , 12)
