Answer:

Option (A)

Step-by-step explanation:

Graph attached shows a function that models the value V of a stock portfolio as a function of time.

y-values on the graph shows the value of V and x-values represent the time.

Lowest point of the curve shows the minimum value of V and highest point of the curve shows the maximum value.

Maximum value of the function → 6.93 at t = 4

Minimum value of the function → 1.05 at t = 15

Therefore, Option (A) will be the answer.

Answer:

Explained below.

Step-by-step explanation:

The rules of the deal are as follows:

(a)

The correct option is: "the money you win".

(b)

The random variable X denotes the amount won or lost.

(c)

The value of X are as follows:

X = {-$6, $5 and $10}

(d)

The probability function of X is as follows:

P (X = 10) = 1/6

P (X = 5) = 1/3

P (X = -6) = 1/2

(e)

Compute the expected value as follows:

[tex]E(X)=\sum x\times P(X=x)\\[/tex]

         [tex]=(10\times\frac{1}{6})+(5\times\frac{1}{3})+(-6\times\frac{1}{2})\\\\=0.333333\\\\\approx $0.33[/tex]

Thus, the average winnings per game is $0.33.

(f)

Since the expected value of the game is a positive amount, the deal will not  lead to me paying up.

Thus, you take the deal.

The number line which can be used to find the distance between (4, -1) and (8,-1) is 1

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

Given the points;

(x1, y1) = (4, -1)

(x2, y2) = (8, -1)

Here, we have the same values of y for both points.

This means that the line that contains both points is a horizontal line.

To find the distance, apply the formula:

[tex]d= \sqrt{(x2-x1)^{2} + (y2-y1)^{2} }[/tex]

Since they have the same y values, the number line to represent the distance between both points must have the points 4 and 8;

Hence, we have;

 [tex]d= \sqrt{(8-4)^{2}+(-1+1)^{2} }[/tex]

   [tex]d= \sqrt{4^{2} + 0^{2} }[/tex]

     d= 4

The distance between both points is 4;

Therefore, the number line that can be used to find the distance between both points is the number line in option A.

13.)x≥−21

2.)x≤−7

10.)x≤10

16.)x≤−4

10. x ≤ 10

11. x ≤ -15

12. x ≥ -12

13. x ≥ -21

16. x ≤ -4

Step-by-step explanation:

2. x ≤ -7 (You want to add 8 to both sides like any equation, but don't forget it is an inequality, not an equation!)

5. x > 36 (You need to multiply by 2, to get rid of the division. So multiply both sides by 2, that gets rid of the 2 on the one side, and you get 36 on the other side when you multiply 18 by 2).

6. x ≤ -40 (You need to multiply by -5. REMEMBER: When you multiply or divide by a negative, you switch the sign. So if it is a < then it would be a > and same with if you had ≤ then it would be ≥ instead).

10. x ≤ 10 (You need to divide by -2. And once again you switch the signs).

11. x ≤ -15 (Add 8, like you did in number 2).

12. x ≥ -12 (Multiply by 6. REMEMBER: Do NOT switch the signs if you the number you are dividing by is in the numerator, or if you multiply and the negative number is first, UNLESS you have 2 negatives.

13. x ≥ -21 (Multiply by 7).

16. x ≤ -4 (Divide by 10).

Answer:

y = 1/2x + 2.5

Step-by-step explanation:

First we want to plug it into the [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. This gets us 6-2/7-(-1) which solves to 4/8 which simplifies to 1/2. This gives us the slope. Now, when using slope intercept form y = mx + b, we can plug our newly found slope in for m and get y = 1/2x + b. To find b plug in any point on the line into the equation, I chose (7,6) because we are given that, and both numbers are positive. Now plug those in for x and y. 6 = 1/2(7). Solve, and get 2.5. are final equation is

y = 1/2x + 2.5

The average price of a ticket originating in Chicago using United Airlines is $1212.40.

Step-by-step explanation:

The data provided is as follows:

                    United Air France British

Chicago         1063              1314          1442

                      1299             1493           1413

                       995             1443          1063

                      1299             1577          1442

                      1406             1314          1575

London         1015             1374          1603

                       856              977           1531

                       802             1043          1079

                       850             1070           807

                       935             1428           870

The data for the price of a ticket originating in Chicago using United Airlines is:

Chicago = {1063, 1299, 995, 1299, 1406}

Compute the average price as follows:

[tex]\bar X=\frac{1}{n}\sum X[/tex]

   [tex]=\frac{1}{5}\times [1063+1299+995+1299+1406]\\\\=\frac{6062}{5}\\\\=1212.40[/tex]

Thus, the average price of a ticket originating in Chicago using United Airlines is $1212.40.

The speed of the train in kilometer per hour is 68.9km/hr.

The rate of change of position of an object in any direction.

[tex]speed = \frac{distance}{time}[/tex]

According to the given question

Distance travelled by commuter train = 21km

Time taken by a train to travel 31 km = 27 minutes = [tex]\frac{27}{60} =0.45hour[/tex]

Therefore, the speed of the train in kilometer per hour is given by

[tex]speed = \frac{31}{0.45}[/tex]

⇒[tex]speed = 68.9km/hr[/tex]

Hence, the speed of the train in kilometer per hour is 68.9km/hr.

14*51=714

Answer:

a) A = 3π/16

b) A = ∑₂°° (π/n⁴) = π⁵/90 − π

Step-by-step explanation:

(a) The area between the curve and the x-axis is:

A = ∫ₐᵇ y (dx/dt) dt

x = ½ (1 − cos t) cos t

dx/dt = ½ (1 − cos t) (-sin t) + ½ sin t cos t

dx/dt = -½ sin t + ½ cos t sin t + ½ sin t cos t

dx/dt = -½ sin t + sin t cos t

dx/dt = -½ sin t (1 − 2 cos t)

y dx/dt = -½ sin t (1 − 2 cos t) × ½ (1 − cos t) sin t

y dx/dt = -¼ sin²t (1 − 3 cos t + 2 cos²t)

y dx/dt = -¼ sin²t + ¾ sin²t cos t − ½ sin²t cos²t

y dx/dt = ⅛ (-2 sin²t) + ¾ sin²t cos t − ½ (sin t cos t)²

y dx/dt = ⅛ (-1 + 1 − 2 sin²t) + ¾ sin²t cos t − ½ (½ sin(2t))²

y dx/dt = ⅛ (-1 + cos(2t)) + ¾ sin²t cos t − ⅛ sin²(2t)

y dx/dt = -⅛ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ (-2 sin²(2t))

y dx/dt = -⅛ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ (-1 + 1 − 2 sin²(2t))

y dx/dt = -⅛ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ (-1 + cos(4t))

y dx/dt = -⅛ + ⅛ cos(2t) + ¾ sin²t cos t − ¹/₁₆ + ¹/₁₆ cos(4t)

y dx/dt = -³/₁₆ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ cos(4t)

A = ∫₀ᵖⁱ [-³/₁₆ + ⅛ cos(2t) + ¾ sin²t cos t + ¹/₁₆ cos(4t)] dt

A = -³/₁₆ t + ¹/₁₆ sin(2t) + ¼ sin³t + ¹/₆₄ sin(4t) |₀ᵖⁱ

A = [-³/₁₆ π + ¹/₁₆ sin(2π) + ¼ sin³π + ¹/₆₄ sin(4π)] − [0 + ¹/₁₆ sin(0) + ¼ sin³0 + ¹/₆₄ sin(0)]

A = -³/₁₆ π

We got a negative answer because the graph traces to the left (x decreases as t increases).  So the area is simply ³/₁₆ π.

b) Each circle has radius 1/n², so the area is π (1/n)² = π/n⁴.

The sum of the areas from n=2 to n=∞ is:

A = ∑₂°° (π/n⁴)

A = ∑₁°° (π/n⁴) − π

A = π ∑₁°° (1/n⁴) − π

A = π (π⁴/90) − π

A = π⁵/90 − π

Step-by-step explanation: C. 2x+3=1/2(4x+2)+2 hopes this helps:)

The equations that are identities are option B x – 4(x + 1) = –3(x + 1) + 1 and option C 2x + 3 = 1/2(4x + 2) + 2.

To check which equation is an identity, we need to simplify each equation and see if it is true for all values of x.

A. 3(x – 1) = x + 2(x + 1) + 1

Expanding the right side:
3(x – 1) = x + 2x + 2 + 1
3x – 3 = 3x + 3-3 = 3

This is a contradiction and cannot be true for any value of x. Therefore, option A is not an identity.

B. x – 4(x + 1) = –3(x + 1) + 1
Expanding both sides:
x – 4x – 4 = –3x – 3 + 1
-3x – 3 = -3x – 3

This equation simplifies to -3x - 3 = -3x - 3, which is true for all values of x. Therefore, option B is an identity.

Similarly,

Option C is an identity.

Option D is not an identity.

Answer:

Options 1) and 3) are correct.

Step-by-step explanation:

R={(A,B)|A⊆B}

Reflexive:

As A⊆A,  [tex](A,A)[/tex]∈ R.

So, R is reflexive

Symmetric:

Let [tex](A,B)[/tex]∈ R. So, A⊆B

Take [tex]A=\{1,2\}\,,\,B=\{1,2,3,4\}[/tex]

Here, A⊆B but B⊄A

So, [tex](B,A)[/tex]∉ R

R is not symmetric

Transitive:

Let [tex](A,B)[/tex]∈ R and [tex](B,C)[/tex]∈ R

So, A⊆B and B⊆C.

Therefore, A⊆C

So,

[tex](A,C)[/tex]∈ R

Hence, R is transitive.

Option 1) is correct.

Antisymmetric:

Let (A,B)∈R and (B,A)∈R

So, A⊆B and B⊆A

Hence, A = B

So, R is antisymmetric

Option 3) is also correct.
