Which is true about investments and risk?

Answer:

For A and B, we have (10, 6)

For C and D, we have (12, 8)

For E and F, we have (12, 8)

Explanation:

To determine the missing numbers along each side of the triangle, we have to

*Add the two numbers at the vertex

*Subtract it from 32

*Divide it by 2

*Add 2 to it to have the 1st number

*Subtract 2 from it to have the 2nd number

So to find the pair of numbers that can be used for A and B, we'll have;

Therefore the missing numbers for A and B are 10 and 6.

So to find the pair of numbers that can be used for C and D, we'll have;

Therefore the missing numbers for C and D are 12 and 8.

So to find the pair of numbers that can be used for E and F, we'll have;

So to avoid repetition of any of the numbers between 4 and 12, we have to add and subtract 1 instead of 2.

Writing the given trigonometry expression: cos(2 tan inverse (x)) as algebraic expression gives

Data given in the question are as follows:

cos(2 tan inverse (x))

Using trigonometry (double angle formula)

cos 2x = 1 - 2sin² x

when x = tan inverse (x)

cos(2 tan inverse (x))  = 1 - 2sin² tan inverse (x)        (1)

cos² x + sin² x = 1

cos² x = 1 - sin² x

cos x = √(1 - sin x)

tan x = sin x / cos x

[tex]tan x = \frac{sinx }{\sqrt{1-sin^{2}x } }[/tex]

squaring all parts of the trigonometry expression and clearing the fraction

[tex]tan^{2}x = \frac{sin^{2} x }{1-sin^{2}x }[/tex]

[tex](tan^{2}x) (1-sin^2x) = sin^2x[/tex]

[tex]tan^{2}x-tan^{2}xsin^2x = sin^2x[/tex]

[tex]tan^{2}x = sin^2x+tan^{2}xsin^2x[/tex]

[tex]tan^{2}x = sin^2x(1+tan^{2}x)[/tex]

[tex]sin^2x = \frac{tan^{2}x}{(1+tan^{2}x)}[/tex]

since tan (tan inverse) (x) = x

[tex]1 - 2sin^2 tan^{-1} (x) = 1 - 2x^2 / (1 + x^2)[/tex]

[tex]=\frac{ 1 + x^2 -2x^2}{1+x^2}[/tex]

[tex]=\frac{ 1 -x^2}{1+x^2}[/tex]

Therefore trigonometry expression cos(2 tan inverse (x)) gives an algebraic expression in the form (1-x²) / (1+x²)

Step-by-step explanation:

The greatest common factors of 2^5 · 5· 11 and 2^3· 5^2 · 7 is equivalent to 2^3 * 5

The largest positive integer that divides each of two or more non-zero integers is known as the greatest common divisor.

This factor must be able to divide all the terms of the expression withour remainder.

Given the numbers 2^5 · 5· 11 and 2^3· 5^2 · 7. Find the factors;

2^5 · 5· 11 = 2^3 * 2^2 * 5 * 11

2^3· 5^2 · 7= 2^3 * 5 * 5 * 7

Since the number 2^3 * 5 is common to both factors, hence the GCF of these numbers 2^5 · 5· 11 and 2^3· 5^2 · 7 is 2^3 * 5

The given inequality has the following solution set

9.52 ≤ x ≤ 22.22

If we express this as an interval, we get [9.52, 22.22].

Here is the inequality which is Kali's earning potential

200 ≤ 15.75x + 50 ≤ 400

To solve the inequality, we must isolate the variable in the center; if we remove 50 from each of the three sides, we get:

200 - 50 ≤ 15.75x + 50 - 50 ≤ 400 - 50

150 ≤ 15.75x ≤ 350

Now we must divide both totals by 15.75, yielding:

150/15.75 ≤ 15.75x/15.75 ≤ 350/15.75

9.52 ≤ x ≤ 22.22

This is the inequality's solution; the solution set expressed as an interval will be [9.52, 22] or 9.52 ≤ x ≤ 22.22

Answer

The equation in point-slope form is

y - 1 = (-10/3) (x + 2)

We can then simplify this by multiplying through by 3 to obtain

3y - 3 = (-10) (x + 2)

3y - 3 = 10x - 20

3y = 10x - 20 + 3

3y = 10x - 17

Explanation

The general form of the equation in point-slope form is

y - y₁ = m (x - x₁)

where

y = y-coordinate of a point on the line.

y₁ = This refers to the y-coordinate of a given point on the line

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

x₁ = x-coordinate of the given point on the line

We can calculate the slope of the line and then use any of the two points given to serve as the point (x₁, y₁) in the equation

For a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as

For this question,

(x₁, y₁) and (x₂, y₂) are (-5, 11) and (-2, 1)

x₁ = -5

y₁ = 11

x₂ = -2

y₂ = 1

Slope = m = (-10/3)

Using the point (-2, 1) as (x₁, y₁), we can write the equation of the line

y - y₁ = m (x - x₁)

y - 1 = (-10/3) (x - (-2))

y - 1 = (-10/3) (x + 2)

We can then simplify this by multiplying through by 3 to obtain

3y - 3 = (-10) (x + 2)

3y - 3 = 10x - 20

3y = 10x - 20 + 3

3y = 10x - 17

1) Since the equation of the circle is given by:

And we've been told the Center (1,-5) and one point located at the circumference, (2,1). So let's find the radius, i.e. the distance from the center to any point to the circumference.

2) Let's use the Formula for the distance between (1,-5) and (2,1), derived from the Pythagorean Theorem:

3) So d = radius, and now we can plug those pieces of information into the formula of the circle:

So we now have the formula for that circle.

Answer:

Radius (R) is equal to the distance between the points (-2,1) and (3,1)

R² = (1 - 5)² + (1 - 1)² = (-24)² + 0 = 579

Let x represent the rental cost for each movie.

Let y represent the rental cost for each video game.

We were told that One month Tony rented 5 movies and 3 video games for a total of 532. This means that

5x + 3y = 32

Also, the month, he rented 2 movies and 12 video games for a total of $83. This means that

2x + 12y = 83

Dividing through by 2, we have

x + 6y = 41.5

x = 41.5 - 6y

Substituting x = 41.5 - 6y into 5x + 3y = 532, we have

5(41.5 - 6y) + 3y = 32

207.5 - 30y + 3y = 32

- 30y + 3y = 32 - 207.5

- 27y = - 175.5

y = - 175.5/- 27

y = 6.5

x = 41.5 - 6(6.5) = 41.5 - 39

x = 2.5

Rental cost for each movie = $2.5

Rental cost for each video game = $6.5

What is Standard form of equation?

The standard form of the equation is defined as;

Ax + By = C

Where, A, B and C are integers.

Given that;

The equation in slope - intercept form as;

⇒ y - 3 = 1/5 (x + 6)

Now,

We convert the equation in standard form as;

Since, The equation in slope - intercept form as;

⇒ y - 3 = 1/5 (x + 6)

Change into standard form as;

⇒ y - 3 = 1/5 (x + 6)

Multiply by 5 both side, we get;

⇒ 5( y - 3) = (x + 6)

⇒ 5y - 15 = x + 6

Add 15 both side, we get;

⇒ 5y - 15 + 15 = x + 6 + 15

⇒ 5y = x + 21

Subtract 21 both side, we get;

⇒ 5y - 21 = x + 21 - 21

⇒ 5y - 21 = x

Subtract 5y both side, we get;

⇒ 5y - 21 - 5y = x - 5y

⇒ - 21 = x - 5y

⇒ x - 5y = -21

After 2.14 hours the trains are exactly 300 miles apart.  

Two trains leave the same station at the same time, one traveling west at a constant speed of 60 miles per hour, the other traveling south at a constant speed of 80 miles per hour.

The time both of them will travel 300 miles can be calculated as follows:

Therefore,

speed = distance / time

distance = speed × time

The train that travel west:

let

t = time of the train that travel west

distance = 60t

The train that travel south:

distance = 80t

Therefore,

total distance = 60t + 80t

300 = 140t

t = 300 / 140

In the above question, the following figure is given, where

The angle inside the circle made by the intersection of two line segments is = 40°

We need to find the angle x made by the angle made by the tangents outside the circle

A line that touches a curve or a circle at one point is said to be tangent.

The point of tangency is the intersection of the tangent line and the curve.

We'll find the value of of angle x using the theorems of the circumscribing   circle.

The sum of opposite angles of a circumscribing quadrilateral is always 180°

Using this property we can write,

40° + x° = 180°
