Answer:

The demand d as a function of price is [tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]

The demand if the price is $ 8 per gallon is 160 millions of gallons.

Step-by-step explanation:

You know that the price-demand equation for gasoline is 0.3d + 4p = 80

To write demand d as a function of price p, you must solve for or isolate demand d, remembering that:

So:

0.3d + 4p = 80

0.3d = 80 - 4p

[tex]d=\frac{80 - 4p}{0.3}[/tex]

[tex]d=\frac{80}{0.3} -\frac{4p}{0.3}[/tex]

[tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]

The demand d as a function of price is [tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]

To determine how much is the quantity demanded if the price is $ 8 per gallon, you simply plug that value into the previously determined expression and perform the corresponding calculations:

[tex]d=\frac{800}{3} -\frac{40*8}{3}[/tex]

[tex]d=\frac{800}{3} -\frac{320}{3}[/tex]

d= 160

The demand if the price is $ 8 per gallon is 160 millions of gallons.

Answer:

[tex]\bold{(x+2))^2+(y-2)^2+(z-2)^2=17}[/tex]

Step-by-step explanation:

Given the center of sphere is: (-2, 2, 3)

Passes through the origin i.e. (0, 0, 0)

To find:

The equation of the sphere ?

Solution:

First of all, let us have a look at the equation of a sphere:

[tex](x-a)^2+(y-b)^2+(z-c)^2=r^2[/tex]

Where ([tex]x,y,z[/tex]) are the points on sphere.

[tex](a, b, c)[/tex] is the center of the sphere and

[tex]r[/tex] is the radius of the sphere.

Radius of the sphere is nothing but the distance between any point on the sphere and the center.

We are given both the points, so we can use distance formula to find the radius of the given sphere:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}[/tex]

Here,

[tex]x_1 =0 \\y_1 =0 \\z_1 =0 \\x_2 =-2 \\y_2 =2 \\z_2 =3[/tex]

So, Radius is:

[tex]r = \sqrt{(-2-0)^2+(2-0)^2+(3-0)^2}\\\Rightarrow r = \sqrt{4+4+9} = \sqrt{17}[/tex]

Therefore the equation of the sphere is:

[tex](x-(-2))^2+(y-2)^2+(z-2)^2=(\sqrt{17})^2\\\bold{(x+2))^2+(y-2)^2+(z-2)^2=17}[/tex]

Answer:

C

Step-by-step explanation:

Because the dolphin increases his elevation, the amount he increases is added to the original elevation to get the second elevation.

Therefore:

-16 3/4 + 5x = -5 1/4

This option is not in the options but if we rearrange the left side from

- 16 3/4 + 5x

to:

5x - 16 3/4

We get the last option C.

Hope this helped!

Answer:

Which of the following graphs show a proportional relationship?

Choose all answers that apply:

The answer is A.

Using the proportional relationship concept, the graph of a straight line through the origin is seen in option (A).

So, option (A) is the correct option.

"If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate."

In a proportional relationship, two quantities vary directly with each other.

We can represent relationships in several ways:

1. An equation in the form of y = kx , where k is the constant of proportionality or unit rate.

2. A graph of a straight line that passes through the origin.

3. A set or table of ordered pairs that show equivalent ratios.

4. A verbal description that describes a describe proportional relationship between two quantities.

Explanation for correct option:

According to the given options

The graph of a straight line through the origin is seen in option (A).

So, option (A) is the correct option.

Explanation for other options:

In option(B),

The graph of a straight line does not passes through the origin.

So, option (B) is not correct

In option(C),

Graph is not given

So, it is also not correct

Hence, the graph of a straight line through the origin is seen in option (A).

So, option (A) is the correct option.

Answer:

a. Line

b. Plane

c. All of R^3

Step-by-step explanation:

In order to answer this question, we need to study the linear independence between the vectors :

1 - A set of three linearly independent vectors in R^3 generates R^3.

2 - A set of two linearly independent vectors in R^3 generates a plane.

3 - A set of one vector in R^3 generates a line.

The next step to answer this question is to analyze the independence between the vectors of each set. We can do this by putting the vectors into the row of a R^(3x3) matrix. Then, by working out with the matrix we will find how many linearly independent vectors the set has :

a. Let's put the vectors into the rows of a matrix :

[tex]\left[\begin{array}{ccc}-2&5&-3\\6&-15&9\\-10&25&-15\end{array}\right][/tex] ⇒ Applying matrix operations we find that the matrix is equivalent to this another matrix  ⇒

[tex]\left[\begin{array}{ccc}-2&5&-3\\0&0&0\\0&0&0\end{array}\right][/tex]

We find that the second vector is a linear combination from the first and the third one (in fact, the second vector is the first vector multiply by -3).

We also find that the third vector is a linear combination from the first and the second one (in fact, the third vector is the first vector multiply by 5).

At the end, we only have one vector in R^3 ⇒ The set of all linear combinations of the set a. is a line in R^3.

b. Again, let's put the vectors into the rows of a matrix :

[tex]\left[\begin{array}{ccc}1&2&0\\1&1&1\\4&5&3\end{array}\right][/tex] ⇒ Applying matrix operations we find that the matrix is equivalent to this another matrix ⇒

[tex]\left[\begin{array}{ccc}1&1&1\\0&1&-1\\0&0&0\end{array}\right][/tex]

We find that there are only two linearly independent vectors in the set so the set of all linear combinations of the set b. is a plane (in fact, the third vector is equivalent to the first vector plus three times the second vector).

c. Finally :

[tex]\left[\begin{array}{ccc}0&0&3\\0&1&2\\1&1&0\end{array}\right][/tex] ⇒ Applying matrix operations we find that the matrix is equivalent to this another matrix ⇒

[tex]\left[\begin{array}{ccc}1&1&0\\0&1&2\\0&0&3\end{array}\right][/tex]

The set is linearly independent so the set of all linear combination of the set c. is all of R^3.

Answer:

RT = 20

Step-by-step explanation:

Given that,

Point S lies on the line segment RT.

We have, ST = 3x-8, RT = 4x and RS = 4x-7

It is clear that, RT = RS+ST

Putting the values, we get :

4x = 4x-7 + 3x-8

Taking like terms together,

4x-4x-3x = -7-8

-3x = -15

x = 5

Put the value of x in RT = 4x.

So,

RT = 4(5)

RT = 20

Hence, length of RT = 20.

Answer:

x > 10/7

Step-by-step explanation:

Take LCM and do cross Multiplication. You will get,
