The given set A = {10, 11, 12, 13}, has the cardinal number n(A) = 4, and it has 15 non-empty subsets.

In the question, we are given a set A = {10, 11, 12, 13}.

We are asked for the cardinal number of the set n(A).

Also, we are asked for the number of non-empty subsets of A.

The cardinal number of any set A is given as n(A), which represents the number of elements in set A.

For the given set A = {10, 11, 12, 13}, the number of elements are 4.

Thus, the cardinal number of the set A is, n(A) = 4.

The number of non-empty subsets of any set A, with cardinal number n, is given by the formula, 2ⁿ - 1.

The given set A = {10, 11, 12, 13}, has the cardinal number n(A) = 4.

Thus, the number of non-empty subsets of set A = 2⁴ - 1 = 16 - 1 = 15.

Thus, the given set A = {10, 11, 12, 13}, has the cardinal number n(A) = 4, and it has 15 non-empty subsets.

The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 370 minutes, the monthly cost will be $76. If the customer uses 750 minutes, the monthly cost will be $114.

(370,76) and (750,114)

A) Find an equation in the form y=mx+b, where x is the number of monthly minutes used and y is the total months of the Regular plan.

slope =[tex]\frac{(114-76}{(750-370)}[/tex] = [tex]\frac{38}{380}[/tex] = [tex]\frac{1}{10}[/tex]√

y = MX + b

Solve for "b"

114 = (    [tex]\frac{1}{10}[/tex])750 + b

114 = 75 + b

b = 39

Answer:: y = ([tex]\frac{1}{10}[/tex])x +39

Customers and customers may or may not be the same thing, but they are two different things. A customer uses the products that a customer has purchased. An ultimate client could also be a consumer, but they might also have bought things for someone else to consume. A middle customer is not at all a consumer. The situation is rather convoluted because final consumers of so-called industrial goods and services are theoretically also consumers because they either consume the goods and services individually or incorporate them into other finished products. They are more frequently referred to as industrial customer or business-to-business customers instead. Similar to how few people refer to clients who purchase services as consumers

The required measure of the angle K  is 110° and the simplified value of the x is 6.

Here,
In a parallelogram sum of the adjacent angle is 180°, So
18x + 2 + 70 = 180
18x + 72 = 180
18x = 180 - 72
18x = 108
x = 6

Now, angle k
= 18x + 2
= 18 * 6 + 2
= 110

Step-by-step explanation:

We need 251.33 gallons of the milk with 7% butterfat and 126.67 gallons of the milk with 4% butterfat to make the desire 378 gallons.

Given,

The amount of milk needed in the dairy = 378 gallons

The quantity of butterfat needed in the milk = 6%

We have to find the amount of milk containing 7% and 4% butterfat used to obtain 378 gallons:

Now,

The amount of milk containing 7% butterfat = x gallons.

The amount of milk containing 4% butterfat = y gallons.

Now, we can have the equation as:

x + y = 378

Percentage of butterfat needed = 6%

0.07x + 0.04y = 0.06 x 378

0.07x + 0.04y = 22.68

Solve for x and y :

x + y = 378        ---------------------- (1)

0.07x + 0.04y = 22.68  -------------- (2)

From Equation (1) :

x + y = 378

x = 378 - y ------------------ Substitute into (2)

0.07(378 - y) + 0.04y = 22.68

26.48 - 0.7y + 0.04y = 22.68

26.48 - 0.03y = 22.68

26.48 - 22.68 = 0.03y

3.8 = 0.03y

y = 3.8 / 0.03

y = 126.67 ---- sub into (1)

x + y = 378

x + 126.67 = 378

x = 378 - 126.67

x = 251.33

Therefore,

Amount of milk containing 7% butterfat = x = 251.33 gallons

Amount of milk containing 4% butterfat = y = 126.67 gallons.

That is,

We need 251.33 gallons of the milk with 7% butterfat and 126.67 gallons of the milk with 4% butterfat to make the desire 378 gallons.

A cartesian plane is a plane with two axes namely x axis and y axis.

A Cartesian plane is a graph with one x-axis and one y-axis and thus is also sometimes known as a x y graph.

These two axes are perpendicular to each other that is they form an angle of 90° with each other.

The origin (O) is in the exact center of the graph and is the point where the two axes intersect.

Numbers to the right of the zero on the x-axis are positive and the numbers to the left of zero are negative. ( as the case in number line as well)

Similarly, the number on the top of the center on y axis are positive and the numbers below are negative.

It can be used to represent any 2 D figure.

Therefore, a cartesian plane is a plane with two axes namely x axis and y axis.

Substitution method

Recall

x+2y=13. equ.1

3x-5y=6. equ.2

equ.1=

x-2y=13

x=13-2y. equ.3

Substitute 'x' into equ.2

3(13-2y)-5y=6

39-6y-5y=6

39-11y=6

collect like terms

39-6=11y

33/11=11y/11

therefore y=3

Substitute 'y' into equ.1, equ.2 or equ.3

Answer:

x = 3 ± √(39)

Step-by-step explanation:

x            6

-----   = -------

(x+5)      x

We can solve using cross products

x * x = 6(x+5)

x^2 = 6x+30

Subtract 6x from each side

x^2 -6x= 6x+30-6x

x^2 -6x= 30

Subtract 30 from each side

x^2 -6x -30 = 30-30

x^2 -6x -30 =0

Using the quadratic formula

x = -b ± √(b^2 -4ac)

     -------------------------

                2a

where  a=1  b = -6  and c = -30

x = -(-6) ± √((-6)^2 -4(1)(-30))

x = 6 ± √(36 +120)

The transformation required to obtain the graph of the function f(x) from the graph of the function g(x) is by stretching the function g(x) horizontally by 3.

When a function is transformed, the curve that represents the graph either "moves to the left/right/up/down," "it expands or compresses," or "it reflects." By moving, extending, compressing, or reflecting the curve rather than directly graphing the function from scratch, function transformations are particularly useful for graphing the functions.

Given:

[tex]f(x) =[/tex] [tex]cos(\frac{x}{3} )[/tex]

[tex]g(x) = cos x[/tex]

As g(x) is the parent function of f(x)

⇒ [tex]f(x) = g( \frac{x}{3})[/tex]

given function [tex]g(x) = cos x[/tex]

Substituting the value of x as [tex]\frac{x}{3}[/tex]

we get,

⇒ [tex]g(\frac{x}{3} ) = cos (\frac{x}{3} )[/tex]

Therefore, the transformation required to obtain the graph of the function f(x) from the graph of the function g(x) is by stretching the function g(x) horizontally by 3.

Using the relation between velocity, distance and time, it is found that the penny has a faster unit rate per hour. It travels about 56.4 kilometers per hour faster.

Velocity is distance divided by time, that is:

v = d/t.

The rocket traveled 208 kilometers in 50 minutes = 5/6 of an hour, hence it's velocity, which is the unit rate, is given by:

v = 208/(5/6) = 208 x 6/5 = 249.6 km/hour.

The penny travels 153 kilometers in a half an hour, hence it's velocity is given by:

v = 153/0.5 = 306.

306 > 249.6, 306 - 249.6 = 56.4, hence:
