Which function is represented by this graph?

Answer:

165 is your cost in dollars

Step-by-step explanation:

d = 15c

11 * 15c = 165c

The value of x will be equal to 14 units.

The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one are congruent to the included angle and corresponding two sides of the other triangle.

Since the two triangles are congruent so the value of x will be calculated as:-

2x  -  9  =  x  +  5

2x  -  x  =   9  +  5

x  =  14

Therefore the value of x will be equal to 14 units.

Hi Student!

The first step that we need to take before trying to solve the problem is that we need to take out important information from the problem.  The first important piece of information that is given to us is that we are trying to find an equation of a line that is parallel to a different line.  This means that our slope is going to be the same as the initial line given.  The second piece of information that is given is a point through which our line passes through which will help us greatly when solving for our line.

The next step that we must take is to solve for y in the given equation so we can see what the slope is.

Subtract 6x from both sides

Divide both sides by 5

Now that we have completely solved for y, we can see that the slope is -1.2 using the y = mx + b formula which states that m is the slope.

Moving onto the next step, we must use the point-slope formula to determine what the new equation is that has the same slope and passes through (-4, -2).

Insert the Values

Simplify the Equation

Distribute the Equation

Subtract 2 from both sides (to isolate y)

Therefore, our final answer for the equation of the line parallel to 6x + 5y = 1 and that passes through (-4, -2) is y = -1.2x - 6.8.

Answer:

[tex]\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]

Given:

[tex]\begin{aligned}\implies \sf V &= \sf \pi (6)^2(18)\\& = \sf 648 \pi \: cm^3\end{aligned}[/tex]

[tex]\textsf{Volume of a cube}=\sf x^3\quad\textsf{(where x is the side length)}[/tex]

Given:

[tex]\begin{aligned}\implies \sf V &= 8^3\\& = \sf 512 \: cm^3\end{aligned}[/tex]

Volume of cylinder - volume of cube

= 684π - 512

= 1532.75204 cm³

    1 litre = 1000 cm³

⇒ 1.5 litres = 1000 × 1.5 = 1500 cm³

As 1500 < 1532.75204, the volume of water poured into the container is smaller than the empty space available in the cylinder.  Therefore, the water will not come over the top of the container.

Step-by-step explanation:

using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

[tex]log_{8}[/tex] (x + 9) + 3 = 3 ( subtract 3 from both sides )

[tex]log_{8}[/tex] (x + 9) = 0 , then

x + 9 = [tex]8^{0}[/tex] = 1 ( subtract 9 from both sides )

x = - 8

Explanation:

Think of a hexagonal room with n = 6 walls, i.e. the floor is a hexagon with n = 6 sides. The floor and ceiling are parallel to each other, and congruent hexagons. That's 2 faces so far. Then we have another 6 faces to account for the walls. This gives 2+6 = 8 faces of a hexagonal prism.

In more general terms, a prism with a base of n sides will have 2 parallel and congruent base faces, and n walls or lateral faces. This gives n+2 total faces.

------------------------

Let's go back to the hexagonal prism. The floor has 6 sides to it, and so does the ceiling. We have 6+6 = 12 edges so far. Then we have another 6 edges where each of the rectangular walls meet up. That gives 12+6 = 18 edges total of this hexagonal prism room.

For any more general case, each base has n sides. That gives 2n sides so far for just the bases. Then add on another n for the lateral edges and we get 3n total edges.

--------------------------

Once again lets revisit the room with the hexagonal floor and ceiling. The floor has 6 vertices and the ceiling has the same vertex count. Therefore, this prism has 6+6 = 12 vertices.

For the general case, each base has n vertices. There are 2 such identical bases giving 2n vertices total.

---------------------------

One way to check the answer:

We could use Euler's Polyhedron Formula which is

F+V-E = 2

where,

For the hexagonal prism we found

Then notice how

F+V-E = 2

8+12-18 = 2

20-18 = 2

2 = 2

This confirms the formula works for a hexagonal prism.

Now let's check it for the more general case

We found earlier that,

So,

F+V-E = 2

n+2+2n-3n = 2

3n-3n+2 = 2

0n+2 = 2

0+2 = 2

2 = 2

This helps confirm the answer for any prism with the base of n sides.

The coordinates of the image of (-3, -7) after the translation will be equal to .(-12,2)

The process of changing the location of the image on the coordinate system will be known as the translation. Here the image is translated as (x-9,y+9).

The given coordinate of the point is:- (-3,-7)

So the translation will be calculated as:-

=(x-9,y+9 )

=(-3-9,-7+9

=(-12,2)

Hence coordinates of the image of (-3, -7) after the translation will be equal to (-12,7)

The number of trucks needed to deliver the rock in one trip will be 6.

Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:

V =  a x b x c

A transport company needs to deliver 500,000 pounds of rocks to a construction site.

The company owns a set of dump trucks- each with a container in the shape of a rectangular prism (figure A).

If each pound of rock has a volume of 0.01 cubic feet.

Then the total volume of rock that the transport company is responsible for.

Volume of rocks = 0.01 x 500,000

Volume of rocks = 5,000 ft³

Then the maximum volume of each dump truck will be

Volume of truck = 12 x 9 x 8

Volume of truck = 864 ft³

Then the number of the trucks are needed to deliver the rock in one trip will be

Number of trucks = 5000 / 864

Number of trucks = 5.787

Radian is a unit of angle, equal to an angle at the centre of a circle whose arc is equal in length to the radius.

Here the given angle in radian is [tex]\dfrac{7\pi}{4}[/tex]

Angle in degrees is converted by multiplying it with [tex]\dfrac{180}{\pi}[/tex].

So the angle in degrees will be:-

[tex]=\dfrac{7\pi}{4}\times \dfrac{180}{\pi}[/tex]

The volume of the cone is 254.85 cubic units

The side length of the equilateral triangle is given as:

l = 12√3

Calculate the radius (r) of the cone using:

r = l/2

r = 12/2√3

r = 6√3

Calculate the height of the cone using:

[tex]h = \sqrt{l^2 + (l/2)^2[/tex]

This gives

[tex]h = \sqrt{(12\sqrt 3)^2 + (6\sqrt3)^2[/tex]

Evaluate

[tex]h = \sqrt{540[/tex]

h = 22.24

The volume of the cone is then calculated as:

V = 1/3πr²h

This gives

V = 1/3π * (6√3)² * 22.24

Evaluate

V = 254.85

Using the normal distribution, it is found that the probability that a data value is between 28 and 35 is given by:

A. 29.6%.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Researching the problem on the internet, the mean and the standard deviation are given by:

[tex]\mu = 26, \sigma = 4[/tex].

As a proportion, the probability that a data value is between 28 and 35 is the p-value of Z when X = 35 subtracted by the p-value of Z when X = 28, hence:

X = 35:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{35 - 26}{4}[/tex]

Z = 2.25

Z = 2.25 has a p-value of 0.988.

X = 28:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{28 - 26}{4}[/tex]

Z = 0.5

Z = 0.5 has a p-value of 0.692.

0.988 - 0.692 = 0.296 = 29.6%, which means that option A is correct.

Answer: y=-1x+5

Step-by-step explanation:

1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.

m = ∆y / ∆x

m = -1 / 1

m = -1

y= -1x + b

2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)

y = mx + b

4 = -1(1) + b

4 = -1 + b

5 = b

3. Plug in the values found into the formula.

y = -1x + 5
