Hello!

What is a slope-intercept line:

 [tex]y = mx + b[/tex]

            [tex]slope = \dfrac{y_2-y_1}{x_2-x_1} =\frac{-4--2}{3-0} =-\dfrac{2}{3}[/tex]

           ==> value of y-intercept is '-2'

Thus the equation is [tex]y=-\dfrac{2}{3}x-2[/tex]

Hope that helps!

Answer: y=-2/3x-2

Step-by-step explanation:

1) Draw a triangle from one point to the next point.

For this example, I will use (-3,0) and (0,-2).

You can see that the number goes down 2 and right 3. From this, you can conclude that the rate is -2/3 using the equation rise/run.

2) Find the y-intercept

Looking at the graph, you can find that the y-intercept is (0,-2).

3) Fill in the y=mx+b

y=-2/3x-2

the answer is

step 1

Find out the measure of angle P

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

P+Q+R=180 degrees

substitute given values

P+70+60=180

P=180-130

P=50 degrees

step 2

Applying the law of sines

QR/sin P=PR/sin 70

substitute given values

QR/ sin 50=5/sin 70

QR=(5/sin 70)*sin 50

Answer:

[tex]15xy+6x[/tex]

Simplify the given expression as shown below

The expresion is:

to find the intercepts with the x axis we have to rplace in the equation y = 0, so:

and we solve for x

the intersection with the x axis is -2

And for the itercepts with the y axis we replace x = 0

and we solve for y

This means that the intersepts with the y axis is -8

Let's draw the figure to better understand the scenario:

Let,

s = the measure of the sides of the square

For us to be able to determine the area, let's first find out the measure of its side.

We will be using the Pythagorean Theorem:

Let's now determine the area of the square:

Therefore, the area of the square is 16.

Answer:

Q is greater than P by 291

Step-by-step explanation:

The terms of these Arithmetic Sequences are odd natural numbers, because their common difference is 2

And, sum of 'n' odd natural numbers starting from 1 = n²

P = 99² - (1) = 9800

Q = 101² - (1 + 3 + 5) = 10192

Q - P = 291

Answer:

264.9 in³

Explanation:

The volume of a cone can be calculated using the following equation:

Where π is approximately 3.14, r is the radius of the cone and h is the height.

So, replacing r by 5 in and h by 10.125 in, we get:

Therefore, the volume of the cone is 264.9 in³

Slope is -1/8 (it is not parallel to given line)

_______________

Slope is 1/8 (it is not parallel to given line)

________________

Slope is -8 (it is not parallel to given line)

The range of the graph is 0 <= M <= 5.5

The range of a function is the set of output values of the graph.

This in other words mean the range of a function is the set of y values of the graph.

The domain

On the graph of the function, we can see that:

The x values start from 0 and it ends at 7.5

This means that the domain is 0 <= x <= 7.5

The range

On the graph of the function, we can see that:

The x values start from 0 and it ends at 5.5

This means that the range is 0 <= M <= 5.5

Answer:

0 <= M <= 5.5

Step-by-step explanation:

This question has to do with the change in the subject of the formula.

So we will proceed thus:

The correct answer, therefore, is the third option:

Answers:

[tex]\cos(\theta) = \frac{-3\sqrt{5}}{7}\\\\\tan(\theta) = -\frac{2}{3\sqrt{5}} = -\frac{2\sqrt{5}}{15}\\\\\csc(\theta) = \frac{7}{2}\\\\\sec(\theta) = -\frac{7}{3\sqrt{5}} = -\frac{7\sqrt{5}}{15}\\\\\cot(\theta) = \frac{-3\sqrt{5}}{2}\\\\[/tex]

=================================================

Explanation:

We're given that [tex]\sin(\theta) = \frac{2}{7}\\\\[/tex]

Plug that into the pythagorean trig identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1\\\\[/tex] and solve for cosine to find that [tex]\cos(\theta) = \frac{-3\sqrt{5}}{7}\\\\[/tex]

I skipped steps in solving so let me know if you need to see them.

Keep in mind that cosine is negative in quadrant 2

------------------

Once you've determined cosine, divide sine over cosine to get tangent

[tex]\tan(\theta) = \sin(\theta) \div \cos(\theta)\\\\\tan(\theta) = \frac{2}{7} \div \frac{-3\sqrt{5}}{7}\\\\\tan(\theta) = \frac{2}{7} \times -\frac{7}{3\sqrt{5}}\\\\\tan(\theta) = -\frac{2*7}{7*3\sqrt{5}}\\\\\tan(\theta) = -\frac{2}{3\sqrt{5}}\\\\\tan(\theta) = -\frac{2\sqrt{5}}{3\sqrt{5}*\sqrt{5}}\\\\\tan(\theta) = -\frac{2\sqrt{5}}{3*5}\\\\\tan(\theta) = -\frac{2\sqrt{5}}{15}\\\\[/tex]

------------------

To determine cosecant, we apply the reciprocal to sine.

[tex]\sin(\theta) = \frac{2}{7} \to \csc(\theta) = \frac{1}{\sin(\theta)} = \frac{7}{2}\\\\[/tex]

Similarly, secant is the reciprocal of cosine

[tex]\cos(\theta) = \frac{-3\sqrt{5}}{7} \to \sec(\theta) = \frac{1}{\cos(\theta)} = -\frac{7}{3\sqrt{5}} = -\frac{7\sqrt{5}}{15}\\\\[/tex]

Depending on your teacher, rationalizing the denominator may be optional.

Lastly, cotangent is the reciprocal of tangent

[tex]\tan(\theta) = -\frac{2}{3\sqrt{5}}\to \cot(\theta) = \frac{1}{\tan(\theta)} = \frac{-3\sqrt{5}}{2}[/tex]

------------------

Side notes:

Sine and cosecant are the only things positive in Q2

Everything else (cosine, tangent, secant, cotangent) are negative in Q2.

We are given the following function:

We will take "-6" as a common factor:

Now, we will complete the square in the expression inside the parenthesis by adding and subtracting the following term:

The Greatest common factors for each pair of numbers are;

1, ( 9 , 15 ) = 3

2. ( 12 , 18 ) = 6

3. ( 15 , 27 ) = 3

4. (30, 54) = 6

What is Greatest common factors?

The highest number that divides exactly into two more numbers, is called  Greatest common factors.

Given that;

The pairs of numbers are;

1, ( 9 , 15 )

2. ( 12 , 18 )

3. ( 15 , 27 )

4. (30, 54)

Now,

Find the Greatest common factors of the pairs of the numbers as;

1, ( 9 , 15 )

LCM of 9 = 3 x 3

LCM of 15 = 3 x 5

So, GCF of 9 and 15 = 3

2. ( 12 , 18 )

LCM of 12 = 2 x 3 x 2

LCM of 18 = 3 x 3 x 2

So, GCF of 12 and 18 = 3 x 2 = 6

3. ( 15 , 27 )

LCM of 15 = 3 x 5

LCM of 27 = 3 x 3 x 3

So, GCF of 15 and 27 = 3

4. (30, 54)

LCM of 30 = 2 x 3 x 5

LCM of 18 = 3 x 3 x 2

So, GCF of 30 and 54 = 3 x 2 = 6

Thus, The Greatest common factors for each pair of numbers are;

1, ( 9 , 15 ) = 3

2. ( 12 , 18 ) = 6

3. ( 15 , 27 ) = 3

4. (30, 54) = 6

The value of m∠Y in triangle XYZ is 99°

An equation is used to show the relationship between two or more numbers and variables.

In triangle XYZ, the angles are angle x, y and z. Hence:

∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)

Substituting:

38 + (5x -11) + (4x -45) = 180

Collecting like terms:

9x - 18 = 180

9x = 198

x = 22

m∠Y = 5(22) - 11 = 99°

m∠Y is 99°
