The correct statement is that set A is a subset of set B, as they contain exactly the same elements. The statements about set B containing the number 4 and set A being infinite are false, while the empty set is a subset of every set, including B.

The correct statement regarding the sets A = {1, 2, 3} and B = {3, 2, 1} is A ⊆ B. This is because every element in set A is also in set B, regardless of the order the elements are listed. Sets are collections of distinct objects and their definition does not depend on the order of the elements. Therefore, A and B have exactly the same members, making them equal sets, and conversely, every set is a subset of itself. This can also be seen as both sets having the same cardinality, which is the number of members in a set, and for both A and B, this is 3.

As for the other statements, the number 4 is not an element of set B (4 ∈ B), the set A is not infinite since it has a finite cardinality of 3 (A is not an infinite set), and the empty set is actually a subset of every set, including B ⊂ \⊆cannot be true.

Based on parallelogram ABCD shown below, the values of x and y include;

x = 17 units.

y = 10 units.

In Euclidean Geometry, a parallelogram is a type of quadrilateral and two-dimensional geometrical figure that has two equal and parallel opposite sides.

Generally speaking, a parallelogram has both pairs of opposite sides parallel to each other and the opposite angles (vertical angles) are congruent:

AB ║ CD

AB = CD

3x - 9 = 42

3x = 42 + 9

3x = 51

x = 51/3

x = 17 units.

Next, we would determine the value of y as follows;

4y - 3 = 37

4y = 37 + 3

4y = 40

y = 40/4

y = 10 units.

The line segment drawn from point A to point A′, after reflecting the triangle over the y-axis, is perpendicular to the y-axis. This is because the reflection mirrors the image across the y-axis resulting a right-angle formation between the line segment and the axis.

The line segment drawn from point A to point A′, after a reflection of Triangle HAM over the y-axis, would be perpendicular to the y-axis. This is because in a reflection over the y-axis, the x-coordinates of the points change sign and the y-coordinates stay the same. This procedure mirrors the image over the y-axis and creates a segment from A to A′ that is perpendicular to the y-axis and bisects the distance between A and A′.

This idea correlates to the vector concept in physics where components of the vector may be viewed as sides of a right triangle. Much like in that context, the line segment from A to A′ and the y-axis form a right angle, hence they are perpendicular.

To solve the problem, we just need to consider that the variable "u" and "v" represents different expressions, and then, perform the operation and add the like terms.

We must remember that the like terms are the terms that share the same variable and the same exponent.

We have that:

Answer:

c=13.2 units

Step-by-step explanation:

step 1

Find the measure of angle C

Remember that the sum of the internal angles of a triangle must be equal to 180 degrees

so

A+B+C=180°

substitute the given values

16°+49°+C=180°

65°+C=180°

C=180°-65°=115°

step 2

Find the measure of c

Applying the law of sines

c/sin(C)=a/sin(A)

substitute the given values and solve for c

c/sin(115°)=4/sin(16°)

c=4(sin(115°))/sin(16°)

c=13.2 units

Answer:

A.  The angle measures are 30°, 60°, and 90°.

on edge

Step-by-step explanation:

If the question provides the angles of a triangle as 30°, 60°, and 90°, or 45°, 45°, and 90°, we are dealing with a right triangle. Depending on the measures of the angles, the triangle can be classified as either a 30-60-90 triangle or a 45-45-90 isosceles right triangle. Without sufficient information, the exact measures of the angles cannot be determined.

When considering a triangle with angle measures provided as options, we recall the fundamental property that the sum of internal angles in any triangle is 180 degrees. The question presents three possible sets of angle measures:

Both of the first two options include a 90° angle, indicating that we are dealing with a right triangle. Right triangles have specific properties and can be classified as either 30-60-90 or 45-45-90 triangles, depending on the measures of the other two angles. A 30-60-90 triangle has angles in the ratio of 1:2:√3, and a 45-45-90 triangle, also called an isosceles right triangle, has two angles of 45° each. The third option implies insufficient information to determine the exact measures of all angles.

Step-by-step explanation:

Hi there!

This is a Rational Function. The process of graphing it takes a lot more hard work than graphing other functions like linear, quadratic, modulus, and so on.

Here a list on how to proceed

First

1) Find the point of intersections by calculating the zeros of the function on the Numerator. In this case, we just have a 1 on top, so our graph won't intercept x-axis.

2) Calculate the vertical asymptotes by calculating the zeros of the function in the denominator, x²+4x=0 S=(0,-4) on green on the graph below.

3) Construct the table of values for x, and y

4) Trace the graph

By analyzing the asymptotes on the graph, we conclude that the correct option is C.

To do it, we need to see at which x-values we have asymptotes. These are the values of x where the denominator becomes equal to zero.

Here we can see that we have asymptotes at:

x = 0 and x = -4

Then the denominator must be a polynomial with roots at x = 0 and x = -4, this is written as:

(x - 0)*(x - (-4)) = x*(x + 4)

So the rational function is something like:

[tex]f(x) = \frac{1}{x*(x + 4)}[/tex]

So the correct option is C.

(f+g)(x)= 5x-11

(f-g)(x)= x-3

The value of the functions (f + g)(x) and (f - g)(x) will be 5x - 11 and x - 3.

It is required to find the value of   (f+g)(x) and (f-g)(x).

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given:

The functions are

f(x) = 3x - 7

g(x) = 2x - 4

We have to find the value of the function (f + g)(x) and  (f-g)(x) we get

According to given question we have,

The value of the function (f +g)(x)

(f + g)(x) = f(x) + g(x)

(f + g)(x) = 3x - 7 + 2x - 4

(f + g)(x) = 5x - 11

The value of the function (f - g)(x)

(f - g)(x) = f(x) - g(x)

(f - g)(x) = 3x - 7 - (2x - 4)

(f - g)(x) = 3x - 7 - 2x + 4

(f - g)(x) = x - 3

Therefore,  the value of the functions (f + g)(x) and (f - g)(x) will be 5x - 11 and x - 3.

Answer:

x = 19

Step-by-step explanation:

Question: find x such that f(x) = 2/3

Given f(x) = (-1/3) x + 7

equate the value of f(x) to be 2/3

hence,

(2/3) = (-1/3)x + 7 (multiply both sides by 3)

(3) (2/3)  = (3) (-1/3)x + (3) 7

2 = -x + 21

x = 21 - 2

x = 19

So to get the output value 2/3 we will input x = 19

A mathematical relationship from a set of inputs to a set of outputs is called a function.

An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.

Clearly, all the values of x and f(x) are satisfying it.

Now, the output is given as 2/3.

So, we can write,

[tex]\frac{2}{3} = -\frac{x}{3} + 7[/tex]

⇒  [tex]\frac{2}{3}-7 = -\frac{x}{3}[/tex]   ( changing the side of 7)

⇒ [tex]-\frac{19}{3} = - \frac{x}{3}[/tex]

⇒ x = 19

So to get the output value 2/3 we will input x = 19

Step-by-step explanation:

g(x) = x^3 − x^2 − 4x + 4

We know the graph will have up to 3 zero's because it is a cubic

g(x) = x^3 − x^2 − 4^x + 4

I will factor by grouping, taking an x^2 from the first 2 terms and -4 from the last 2 terms

  g(x)=  x^2(x-1) -4(x-1)

Now factor out x-1

  g(x)= (x-1)(x^2 -4)

We can factor the (x^2-4) as a difference of squares

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

Using the zero product property

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

x-1 =0   x-2 =0   x+2=0

We have zeros at x=1   x=2  and x=-2

Then we can plot points to determine where the function is between the points We will pick negative infinity 0 1.5 and infinity

at g(-inf) =  -inf  because x^3 dominates and that goes to -infinity

at g(0) = 0+000+4 =4

at g(1.5) =-.875

at  g(inf)=because x^3 dominates and that goes to infinity

Part A) [tex]\$42,888.48[/tex]  

Part B) [tex]A=\$22,304[/tex]

Part C) The graph in the attached figure

Step-by-step explanation:

Part A) What will the account be worth in 20 years?

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=20\ years\\ P=\$8,500\\ r=0.0812\\n=12[/tex]  

substitute in the formula above  

[tex]A=8,500(1+\frac{0.0812}{12})^{12*20}[/tex]  

[tex]A=8,500(1.0068)^{240}[/tex]  

[tex]A=\$42,888.48[/tex]  

Part B) What if the deposit were compounded monthly with simple interest?  

we know that

The simple interest formula is equal to

[tex]A=P(1+rt)[/tex]

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=20\ years\\ P=\$8,500\\r=0.0812[/tex]

substitute in the formula above

[tex]A=8,500(1+0.0812*20)[/tex]

[tex]A=\$22,304[/tex]

Part C) Could you see the situation in a graph? From what point one is better than the other?

Convert the equations in function notation

[tex]A(t)=8,500(1.0068)^{12t}[/tex] ------> equation A

[tex]A(t)=8,500(1+0.0812t)[/tex]  -----> equation B

using a graphing tool  

see the attached figure  

Observing the graph, from the second year approximately the monthly compound interest is better than the simple interest.

The retirement account will be worth $27,627.24 after 20 years with compound interest and $23,180 with simple interest. Compound interest grows at a faster rate and becomes better than simple interest when the compounding periods are more frequent.

To calculate the value of the retirement account after 20 years with compound interest, we can use the formula A = P(1 + r/n)^(nt), where A is the final amount, P is the principal deposit, r is the interest rate, n is the number of times compounded per year, and t is the number of years. In this case, P = $8,500, r = 8.12%, n = 12 (monthly compounding), and t = 20. Plugging in these values, we get A = $8,500(1 + 0.0812/12)^(12*20) = $27,627.24.

If the deposit were compounded monthly with simple interest, we can use the formula A = P + (P*r*t), where A is the final amount, P is the principal deposit, r is the interest rate, and t is the number of years. In this case, P = $8,500, r = 8.12%, and t = 20. Plugging in these values, we get A = $8,500 + ($8,500 * 0.0812 * 20) = $23,180.

To compare the two situations on a graph, we can plot the value of the retirement account over time for both compound and simple interest. We would see that the compound interest account grows at a faster rate and reaches a higher value compared to the simple interest account. Compound interest becomes better than simple interest when the compounding periods are more frequent, as it allows the interest to be reinvested more often and generate additional earnings.

B is the center of the circle.

Point B is established as the center of the circle because it is equidistant from the circumference. This property defines B as the central point from which all points on the circle are equally distant, confirming its role as the circle's center.

In the given scenario, the information provided indicates that point B is equidistant from the circumference of the circle. This property characterizes point B as the center of the circle.

To articulate this differently, since B is equidistant from any point on the circle, it serves as the central point from which all points on the circle are equally distant.

Answer:

See below in bold.

Step-by-step explanation:

A.  On one roll the possible ways to get a sum of 5 is (2,3, ) and (4, 1).

There are 36 possible outcomes from the one roll of the 2 dice.

So the probability of getting  a sum of 5 on one roll =  2/36 = 1/18.

So the probability of 5 on 4 rolls = (1/18)^4

= 1/104976.

B.  

The probability of the first 3 rolls being a 5 and the last one being not 5

= (1/18)^3 * (17/18)

= 17/104976

There are 4 ways to  pick 3 out of 4 so the required probability

=  4 * 17/104976

= 68/104976.

Final answer:
