The x intercept of y = -2x - 21 is  [tex]\frac{-21}{2}[/tex]

The y intercept of y = -2x - 21 is -21

What is x - intercept and y - intercept of a line?

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The given equation of line is

y = -2x - 21

For x intercept, we have to put y = 0

[tex]-2x - 21 = 0\\2x = -21\\x = \frac{-21}{2}[/tex]

So the x intercept is [tex]\frac{-21}{2}[/tex]

For y intercept, we put x = 0

[tex]y = -2\times 0 -21\\y = -21[/tex]

The y intercept is -21

The exact value of the sine of angle 78° sin(78°) is presented as follows;

[tex]sin(78^{\circ}) = \dfrac{\sqrt{5}-1+\sqrt{\sqrt{5}\cdot \left(6+6\cdot \sqrt{5} \right) } }{8}[/tex]

The sine of an angle is found by taking the ratio of the opposite side to the hypotenuse side of a right triangle that has the specified angle.

The sine of angle 78° is found from the sine of the sum of two angles (60° + 18°)  as follows;

sin(78°) = sin(60° + 18°)

sin(A + B) = sin(A)·cos(B) + cos(A)·sin(B)

Therefore, sin(78°) = sin(60° + 18°)  = sin(60)·cos(18°) + cos(60°)·sin(18°)

Where, 18° = A, we have;

5·A = 90°

2·A = 90° - 3·A

sin(2·A) = sin(90° - 3·A) = cos(3·A)

2·sin(A)·cos(A) = 4·cos³(A) - 3·cos(A)

2·sin(A)·cos(A) - (4·cos³(A) - 3·cos(A)) = 0

2·sin(A) - (4·cos²(A) - 3) = 0

2·sin(A) - (4·(1 - sin²(A)) - 3) = 0

4·sin²(A) - 2·sin(A) - 1 = 0

Which gives;

[tex]sin(A) = \dfrac{-1\pm \sqrt{5} }{4}[/tex]

cos²(18°) = 1 - sin²(18°)

cos(18°) = √(1 - sin²(18°))

[tex]cos(18^{\circ}) =\sqrt{1 - \left( \dfrac{\sqrt{5} -1 }{4}\right)^2} = \dfrac{1}{4} \cdot \sqrt{10+2\cdot \sqrt{5} }[/tex]

[tex]cos(18^{\circ}) = \dfrac{1}{4} \cdot \sqrt{10+2\cdot \sqrt{5} }[/tex]

Therefore;

[tex]sin(78^{\circ})=\dfrac{\sqrt{3} }{2} \cdot \left( \dfrac{1}{4} \cdot \sqrt{10+2\cdot \sqrt{5} }\right) +\dfrac{1}{2} \cdot \left( \dfrac{\sqrt{5} -1 }{4}\right)= \dfrac{\sqrt{5}-1+\sqrt{\sqrt{5}\cdot \left(6+6\cdot \sqrt{5} \right) } }{8}[/tex]

A triangle is created geometrically by the intersection of three line segments.

Step-by-step explanation:

1/8*305000

Answer:

150% = 132 cm, 25%= 22 cm, 100%= 88 cm

Given:

Height of Odalis = 132 cm

This height is 150%

Divided into 6 parts.

To find: Different percentages of Dallas's Height

Solution:

Dalia's Height = Odalis height * (100/150)

= 132 cm * (2/3)

= 88 cm.

150% of Dallas's Height is 132 cm.

25% of Dalia's Height =  1/4 * 88 = 22 cm

100% of Dalia's Height = 88 cm.

This can also be taken by parts.

6 parts =  150%

1 part =  150/6 = 25%

And 6 parts = 132 cm,

so, 1 part = 132/6 = 22cm.

so , 25% = 1 part= 22cm.

100% = 4 parts = 22*4 = 88 cm.

150% = 6 parts = 22*6 = 132 cm.

Hence, 150% = 132 cm

25%= 22 cm

100%= 88 cm

When red is the first one , blue the second and green the third one (and as you can see, all of them share the vertex (-2, 3)).

The vertex of a quadratic equation:

a[tex]x^{2}[/tex]+bx + c = y

is located at :

x = -b/2a.

In this case, x = -2

Then,

-b/2a = -2

And we also have that:

a[tex](-2)^2[/tex] -2b + c = 3

Then we have two equations:

-b/2a = -2

a[tex](-2)^2[/tex] -2b + c = 3

We have only equations and 3 variables, So we can just give the variable c different values and we will find different quadratic equations that are not equivalent.

Let's begin with c = 0 ,Our equations are:

-b/2a = -2

a[tex](-2)^2[/tex] -2b + 0 = 3

In the first equation we can isolate b and get :

b = 4a

Now we can replace this in the other equation and solve this for a.

4a + 4a x -2 = 3

-4a = 3

a = -3/4

then:

b = 4a = 4 x -3/4 = -3

The first quadratic equation is:

(-3/4)[tex]x^{2}[/tex] - 3x = y

Now, To find the second let's use a different value of c.

c = 1

b = 4a

a[tex](-2)^2[/tex] -2b + 1 = 3

Let's solve in the same way as before:

4a + 4a x -2 + 1= 3

-4a = 2

a = 2/-4 = 1/-2

b = 4 x -1/2 = -2

Then our equation is :

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

For the last equation, let's use c = 2

then our equation are:

b = 4a

a(-2)^2 - 2b +2 = 3

Same as before, replace the first equation in the second

4a + 4a x-2 +2 = 3

-4a +2 = 3

-4a = 1

a = -1/4

Then:

b = 4 x (-1/4) = -1

Our third equation is :

(-1/4)x^2 - x + 2 = y

What is Function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

What is domain?

The domain of a function is the set of values that we are allowed to plug into our function.

What is range?

Since you walk 10km North then turn and walk 5km East, your displacement from where you started is approximately 11.18 km.

From the information given, we have that you walked 10 km north (which represents the vertical side of the triangle) and 5 km east Using the Pythagorean theorem, the displacement (d) can be determined  as;

In Mathematics, a graph simply refers to a type of chart that is typically used for the graphical representation of data on both the horizontal and vertical axes of a cartesian coordinate, which are the x-coordinate and y-coordinate.

Next, we would translate the word sentence into an inequality as follows:

x + y greater than or equal to 500 ⇒ x + y ≥ 500

Subtracting x from both sides of the inequality, we have the following equation:

x + y - x ≥ 500 - x

y ≥ 500 - x
