Answer 1

1. Answer (D). By the law of sines, we have [tex]\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}[/tex] in any [tex]\triangle ABC.[/tex]

2. Answer (C). The law of cosines, [tex]c^2=a^2+b^2-2ab\cos C,[/tex]accepts up to three sides and an angle as an input.

3. Answer (D). Although this triangle is right, we are not given enough information to uniquely determine its sides and angles - here, we need either one more side or one more angle.

4. Answer (D). Don't get tripped up by answer choice (C) - this is just a rearrangement of the statement of the law of cosines. In choice (D), the signs of [tex]a^2[/tex] and [tex]2ab\cos C[/tex] are reversed.

5. Answer (B). By the law of sines, we have [tex]\frac{5}{\sin 40^\circ}=\frac{3}{\sin\theta}.[/tex] Solving gives [tex]\theta\approx \boxed{23^\circ},157^\circ.[/tex] Note that this is the ambiguous (SSA) case of the law of sines, where the given measures could specify one triangle, two triangles, or none at all!

6. Answer (A). Since we know all three sides and none of the angles, starting with the law of sines will not help, so we begin with the law of cosines to find one angle; from there, we can use the law of sines to find the remaining angles.

What is the slope of the line that passes through the points (-8, -3) and
(-12, -3)? Write your answer in simplest form.

Answers

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (- 12, - 3)

m = [tex]\frac{-3+3}{-12+8}[/tex] = [tex]\frac{0}{-4}[/tex] = 0

Slope is rise per run. Rise is difference of y ordinates and run is difference of corresponding x abscissa.

The slope of the line that passes through the given points is 0

Given that:The two specified points are: (-8,-3), and (-12, -3)To find:


Slope of the line that passes through given points.

Finding the slope of a line passing through given points:

In graphing, we use Cartesian plane and assume y axis to be perpendicular and mostly we take height or depth related stuffs on y axis, that's why y ordinates will be considered to calculate the rise and x axis is like flat ground, thus x abscissa will be used to calculate the run.

Let the points' coordinates are denoted by symbols as:

[tex](x_1, y_1) = (-8,-3)\\ (x_2, y_2) = (-12, -3)\\ [/tex]

[tex]slope = \dfrac{rise}{run} = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{(-3) - (-3)}{(-12)-(-8)} = \dfrac{0}{-4} = 0[/tex]

Slope is zero means you run whatever, the rise is 0, which means the line is not going to rise and stay flat (horizontal).

x = 19° ; Write 19° in the box ( don't forgot ° or answer will be incorrect )

Step-by-step explanation:

If XW ║YZ, we can tell that YW is a transversal, as YW ∩ XW, YX;

By alternate interior angles, ∠ ZYW ≅ ∠ YWX, so that ⇒

m∠ ZYW = m∠ YWX,

m∠ YWX = 2x, ⇒ given m∠ ZYW = 2x

By ∑ of angles in triangle Theorem;

m∠ YXW + m∠ XYM + m∠ YWZ = 180° ⇒ through substitution,

( 3x - 5 ) + 90 + ( 2x ) = 180 ⇒ now apply algebra,

3x - 5 + 90 + 2x = 180 ⇒ combine like terms,

3x + 2x - 5 + 90 = 180 ⇒ add,

5x + 85 = 180 ⇒ subtract 85 from either side of equation,

5x = 95, divide 5 on either side,

x = 19°

Find the value of n 5^10 ÷ 5^8=(1/5)^n

Answers

Answer:

5^10 / 5^8 = 5^2 = 25 so the equation becomes 25 = (1/5) ^ n. This means that n = -2.

Answer:

[tex]n=-2[/tex]

Step-by-step explanation:

[tex]\frac{5^{10}}{5^8}=(\frac{1}{5})^n[/tex]

Use the law of exponents.

[tex]5^{10-8}=\left(\frac{1}{5}\right)^n[/tex]

1/5 can be written with a base of 5.

[tex]5^{10-8}=\left(5^{-1}\right)^n[/tex]

Cancel the base 5 on both sides.

[tex]10-8=-1\times \:n[/tex]

[tex]2=-n[/tex]

Multiply both sides with -1.

Step-by-step explanation:

When you graph, you can see that the Line crosses the x at (-3,0) and then passes through the y at (0, 12)

Answer:

D

Step-by-step explanation:

To find the intercepts, set the variable you are not trying to find to 0. Also, in case you don't know, f(x) and y are the same thing here. So on this question, it would be:

X-Intercept:

0=4x+12

-12=4x

-3=x

so x intercept is (-3,0)

Y-Intercept:

y=4(0)+12

y=12

so y intercept is (0,12)

Problema:1,745 kilómetros de distancia entre Mérida, Yucatán y Ciudad Victoria, Tamaulipas.1: 100 000 Escala en el mapa.¿Cuántos centímetros representan estos kilómetros en el mapa?

Answers

Answer:

1745 centimeters.

Step-by-step explanation:

The first thing is to pass the kilometers to centimeters, we know 1 km equals 100000 cm, therefore:

1745 km * 100000 cm / 1 = 174500000 cm

Now, when applying the scale, we have that it is 1: 100000, so we apply the scale:

174500000 * 1/100000 = 1745

That is to say that on the map those 1745 kilometers represent 1745 centimeters.

liz is installing a tile backsplash. if each tile is an equilateral triangle with sides that measures 6 cm in length how many tiles does she need to cover an area of 1800 cm²

Answers

Answer:

  116 tiles

Step-by-step explanation:

You want to know the number of 6 cm equilateral triangle tiles required to cover 1800 cm².

Area

The area of an equilateral triangle of side s is given by the formula ...

  A = (√3/4)s²

The area of a 6 cm equilateral triangle tile is ...

  A = (√3/4)(6 cm²) = 9√3 cm² ≈ 15.588 cm²

Tiles

The number of tiles required is the total area divided by the area per tile:

  1800 cm² / (15.588 cm²/tile) ≈ 115.47 tiles

In order to cover 1800 cm², Liz will need 116 triangular tiles.

Answer:

100 tiles

Step-by-step explanation:

Each tile is an equilateral triangle with sides 6 cm in length, so the area of each tile can be found using the formula for the area of a triangle:

[tex]\sf:\implies{A = (b \times h) / 2}[/tex]

where b is the base and h is the height.

Since each side of the triangle is 6 cm, the base and height of the triangle are both 6 cm, so:

[tex]\sf:\implies{A = (b \times h) / 2}[/tex]

[tex]\sf:\implies{A = (6 \times 6) / 2}[/tex]

[tex]\sf:\implies{A =18}[/tex]

So each tile has an area of 18 cm².

To find the number of tiles needed to cover an area of 1800 cm², divide the total area by the area of each tile:

[tex]\sf:\implies{A = 1800 / 18}[/tex]

[tex]\sf:\implies{A = 100}[/tex]

Therefore, Liz needs 100 tiles to cover an area of 1800 cm².
