Find P(not rolling 1, 3, 4, or 5) with one number cube.

Step-by-step explanation:

Triangles can be solved if you know either of three pieces of information:

You can solve for the remaining sides and angles using law of sine and law of cosine.

Law of sine:

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

Law of cosine:

c² = a² + b² − 2ab cos C

Here, A is the angle opposite side a, B is the angle opposite side b, and C is the angle opposite side c.

Law of cosine can also be written as:

b² = a² + c² − 2ac cos B

a² = b² + c² − 2bc cos A

And law of sine can also be written as:

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

(Notice that when C = 90°, law of cosine becomes Pythagorean theorem.)

Triangle theorems, like the Pythagorean theorem, are used to establish relationships between the sides of triangles and solve problems. These theorems are used to find unknown sides of triangles when other sides are known. Understanding and applying these theorems can enhance your problem-solving skills in several disciplines.

Theorems about triangles, such as the Pythagorean Theorem, can be used to solve various types of mathematical and real-life problems. The Pythagorean Theorem establishes a relationship between the sides of a right-angled triangle. It states that the square of the hypotenuse (side opposite the right angle, labeled 'c') is equal to the sum of the squares of the other two sides (labeled 'a' and 'b'). This relationship is represented by the equation: a² + b² = c².

To use this theorem in solving problems, usually, two sides of a right triangle are known, and the other side is what we need to find out. For example, if the lengths of a and b are known, then c can be found using the formula c = √a² + b². Similarly, if c and one of the other sides are known, the unknown side can be found by rearranging the Pythagorean theorem equation.

Equipped with the understanding of the Pythagorean theorem and other triangle theorems, you can combine various problem-solving strategies to tackle a vast array of problems. This reasoning skill is useful not only in mathematics but also in science disciplines and in everyday life.

Answer:

JM ≈ 12.9 miles

Step-by-step explanation:

The length of the arc is calculated as

arc = circumference × fraction of circle

     = πd × [tex]\frac{90}{360}[/tex]

JM = π × 16.4  × [tex]\frac{1}{4}[/tex]

     = [tex]\frac{16.4\pi }{4}[/tex] ≈ 12.9

The length of the arc JM will be 12.88 miles.

Let r is the radius of the sector and θ be the angle subtends by the sector at the center. Then the arc length of the sector of the circle will be

Arc = (θ/360) 2πr

The diameter is 16.4 miles. Then the radius will be

r = d / 2

r = 16.4 / 2

r = 8.2 miles.

And angle (θ) will be 90 degrees.

Then the length of the arc JM will be

Arc = (90/360) 2π x 8.2

Arc = 12.88 miles

To find the probability of drawing certain colour of balls, we first need to find the total number of balls:

5 + 7 +5 = 17

For the number of red balls that need to be added

The original probability of drawing a red ball:

red ball/ total number of balls

= 5/17

To find the number of balls required, we can set an equation.

Let the number of red balls that need to be added be x.

5+x / 17+x = 5/6

(5+x) x 6 = (17+ x) x5

30 +  6x = 85 + 5x

6x - 5x = 85 - 30

x = 55

Therefore, 55 red balls need to be added.

For the number of black balls that need to be added

The original probability of drawing a white ball:

white ball/ total number of balls

=5/17

To find the probability required, we can set an equation.

Let the number of black balls that need to be added be y.

5/ 17 + y = 1/6

5 x 6 = 17 + y

30 = 17 + y

30 - 17 = y

y = 13

Therefore, 13 black balls need to be added.

Answer:

17/25

Step-by-step explanation:

First, convert the decimal into a fraction. To do so, move the decimal point to the right two place values and place over 100.

0.68 = 68/100

Next, simplify. Divide common factors. Remember, what you do to one side, you do to the other. Divide 4 from both sides:

(68/100)/4 = (17/25)

17/25 is your answer.

~

0.68 can be expressed as the fraction 17/25 in the lowest terms.

Step 1: Let x be the decimal representation of the fraction.

x = 0.68

Step 2: Since there are two digits after the decimal point, we can multiply both sides of the equation by 100 to eliminate the decimal.

100x = 68

Step 3: Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which in this case is 4.

100 ÷ 4 = 25

68 ÷ 4 = 17

The simplified fraction is:

0.68 = 17/25

Therefore, 0.68 can be expressed as the fraction 17/25 in the lowest terms.

Answer:

y=(6(x+6)(x-3))/((x-2)(x+3))

Step-by-step explanation:

The vertical asymptote should be in the denominator. The x-interceps should be in the numerator. Because we have horizontal asymptote y=6, then we have to put 6 in the numerator. the horizontal asymptote is the leading coefficient of the numerator ÷ the leading coefficient of the denominator, when the degree of the numerator and denominator are the same.

Given the horizontal asymptote, vertical asymptotes and x intercepts, the equation of the rational function is y = 6((x+6)(x-3))/((x-2)(x+3)). The vertical asymptotes are found by setting the function's denominator equal to zero, while the x-intercepts come from setting the numerator to zero.

In this question, we are asked to write the equation of a rational function based on given conditions. The function's vertical asymptotes are located at x = 2 and x = -3, and has x-intercepts at (-6,0) and (3,0), with a horizontal asymptote at y = 6.

The general form of a rational function is y = (ax+b)/(cx+d). Asymptotes help define the behavior and boundaries of the function. In this situation, we can set the denominator of our function equal to zero to find our vertical asymptotes, giving us (x-2)(x+3). To achieve our stated x-intercepts, we set the numerator equal to zero, providing (x+6)(x-3). Combining these, the function becomes y = ((x+6)(x-3))/((x-2)(x+3)). The output of the function approaches the horizontal asymptote as x approaches infinity. Thus to have y = 6 as our horizontal asymptote, we adjust our function to maintain this behaviour, settling on y = 6((x+6)(x-3))/((x-2)(x+3)).

Answer:

The correct option is 3.

Step-by-step explanation:

The given equation is

[tex]2x^2+12x-14=0[/tex]

It can be written as

[tex](2x^2+12x)-14=0[/tex]

Taking out the common factor form the parenthesis.

[tex]2(x^2+6x)-14=0[/tex]

If an expression is defined as [tex]x^2+bx[/tex] then we add [tex](\frac{b}{2})^2[/tex] to make it perfect square.

In the above equation b=6.

Add and subtract 3^2 in the parenthesis.

[tex]2(x^2+6x+3^2-3^2)-14=0[/tex]

[tex]2(x^2+6x+3^2)-2(3^2)-14=0[/tex]

[tex]2(x+3)^2-18-14=0[/tex]

[tex]2(x+3)^2-32=0[/tex]             .... (1)

Add 32 on both sides.

[tex]2(x+3)^2=32[/tex]

The vertex from of a parabola is

[tex]p(x)=a(x-h)^2+k[/tex]        .... (2)

If a>0, then k is minimum value at x=h.

From (1) and (2) in is clear that a=2, h=-3 and k=-32. It means the minimum value is -32 at x=-3.

The equation [tex]2(x+3)^2=32[/tex] reveals the minimum value for the given equation.

Therefore the correct option is 3.

The correct answer is option 3. [tex]2(x + 3)^2 = 32[/tex].

To find the minimum value of the quadratic equation [tex]2x^2 + 12x - 14[/tex] = 0, we can rewrite it in vertex form, which reveals the minimum or maximum value of a quadratic function.

The given options are attempts at rewriting the quadratic equation in vertex form. Let’s rewrite the equation:

First, complete the square:

1. Start with the equation: [tex]2x^2 + 12x - 14[/tex]

2. Factor out the coefficient of x² from the first two terms: [tex]2(x^2 + 6x) - 14[/tex]

3. Complete the square inside the parentheses:
- Take [tex](\frac{6}{2})^2 =9[/tex] - Add and subtract 9 inside the parentheses: [tex]2(x^2 + 6x + 9 - 9) - 14[/tex]
- Simplify inside the square: [tex]2((x + 3)^2 - 9) - 14[/tex]

4. Distribute and simplify: [tex]2(x + 3)^2 - 18 - 14 = 2(x + 3)^2 - 32[/tex]

Comparing this with the options, we have [tex]2(x + 3)^2 = 32[/tex].

The correct answer is: [tex]2(x + 3)^2 = 32[/tex].

Answer:

4:3

Step-by-step explanation:

Given that P divides segment MN into 4/7, let MN to be x units in length then

MP = 4/7 x =4x/7 --------(i)

But MN =MP+PN so;

x=4x/7 +PN

x- 4X/7 =PN

3x/7 =PN ----------(ii)

To get the ratio of MP:PN

MP: PN

4x/7:3x/7

MP/PN = 4x/7 / 3x/7

MP/PN =4/3

MP:PN = 4:3

Answer: 4:3

Step-by-step explanation:

Given : A point P is 4/7 of the distance from M to N.

∴ Let the distance between M to N be d.

[tex]\Rightarrow\ MP=\dfrac{4}{7}\times d=\dfrac{4d}{7}[/tex]

Also,  the point P partition the directed line segment from M to N .

Thus , MN = MP+PN

[tex]\Rightarrow\ d=\dfrac{4d}{7}+PN\\\\\Rightarrow\ PN= d-\dfrac{4d}{7}=\dfrac{7d-4d}{7}\\\\\Rightarrow\ PN=\dfrac{3}{7}d[/tex]

Now, the ration of MP to PN will be :-

[tex]\dfrac{MP}{PN}=\dfrac{\dfrac{4d}{7}}{\dfrac{3d}{7}}=\dfrac{4}{3}[/tex]

∴ Point P partitioned the line segment MN into 4:3.

Answer:

y=2x-3

Step-by-step explanation:

The slope-intercept form of a linear equation is y=mx+b where m is the slope and b is the y-intercept.

The y-intercept is where it crosses the y-axis.  It cross the y-axis in your picture at -3 so b=-3.

Now the slope=rise/run.  So starting at (0,-3) we need to find another point that crosses nicely on the cross-hairs and count the rise to and then the run to it.  So I see (1,-1) laying nicely.  So the rise is 2 and the run is 1.

If you don't like counting.  You could just use the slope formula since we already identified the two points as (-1,1) and (0,-3).

The way I like to use the formula is line up the points and subtract vertically then put 2nd difference over 1st difference.

(0,-3)

-(1,-1)

----------

-1     -2

So the slope is -2/-1 or just 2.

We have that m is 2 and b is -3.

Plug them into y=mx+b and you are done.

y=2x-3.

Slope intercept equation of the line is y = 2x - 3.

Slope intercept form gives the graph of a straight line and is represented in the form of y=mx + c.

By checking the graph by drawing manually.

From that we get the equation

y = 2x - 3

Comparing above equation with the standard slope-intercept form y = mx +c, we get

Slope : m = 2

Now, given equation can be re-written as :

2x - y = 3

Divide by 3 on both sides

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

[tex]\frac{x}{\frac{3}{2} } -\frac{y}{3} =1[/tex]

Comparing above equation with intercept form:

[tex]\frac{x}{a}+\frac{y}{b}=1[/tex], we get

x-intercept : [tex]a=\frac{3}{2}[/tex]

y-intercept : [tex]b=-3[/tex]

Now the given straight line intersects the coordinate axes at [tex](\frac{3}{2} ,0)[/tex] and [tex](0,-3)[/tex]. Specify these plots on XY-plane & join by a straight line to get a plot.

Statement 1, 2 and 4 are true where as statement 3 is not true.

Step-by-step explanation:

Statement 1: The y-intercept is -1

Point (3/8, 1/2)

Slope = m = 4

y = mx + c

1/2 = 4(3/8) + c

1/2 = 3/2 + c

1/2 = 3/2 + 2c/2

-2 = 2c

c = -1

This statement is true as the y-intercept is -1.

Statement 2: The slope intercept equation is y= 4x - 1

slope = m = 4

y-intercept = c = -1

y = mx + c

y = 4x - 1

This statement is true as the slope intercept equation is y= 4x -1

Statement 3: The point slope equation is y - 3/8 = 4 (x - 1/2)

Point slope equation: y - y1 = m (x - x1)

Points: (x, y) (3/8, 1/2)

y1 = 1/2

x1 = 3/8

Slope = m = 4

y - 1/2 = 4 (x - 3/8)

This statement is not true as the slope intercept equation is y - 1/2 = 4 (x - 3/8) instead of y - 3/8 = 4 (x - 1/2).

Statement 4: The point (3/8, 1/2) corresponds to (x1, y1) in the point slope form of the equation

This statement is true as shown in statement 3's explanation where x1 = 3/8 and y1 = 1/2

Answer:

I believe the answer is C.

The trigonometric function gives the ratio of different sides of a right-angle triangle. The correct option is C.

The trigonometric function gives the ratio of different sides of a right-angle triangle.

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

To find the measure of angle A, we need to use the tangent trigonometric function this is because except for the hypotenuse of the triangle the other two sides of the equation are known.

Therefore, the equation of the tangent function of trigonometry for angle A can be written as,

tan(A) = Perpendicular /Base
