Hola alguien puede ayudarme a resolver estos ejercicios por favor Ejercicios de intervalos 1.- Escribe en todas las formas posib

yawa3891 [41]

Answer:

Tenemos 3 formas de escribir cada intervalo, una es con solo texto, la otra es usando los símbolos { <, >, ≤, ≥ }, y la última es con intervalos, donde:

( se usa para " < x "

) se usa para " > x "

[ se usa para " ≤ x "

] se usa para " ≥ x "

a) -2 ≤ x ≤3

Esto se escribe como:

"números mayores o iguales que -2 y menores o iguales que 3"

[-2, 3]

b) Números mayores que –1

Las otras formas de escribir esto son:

-1 < x

y no tenemos limite mayor, entonces:

(-1, ∞)

con -∞ y ∞ siempre se usan los símbolos ( o )

c) (–[infinity], –5]

Las otras notaciones son:

"Un numero menor o igual que -5"

x ≤ -5

d) Números mayores o iguales que –7 y menores que 19

Las otras notaciones son:

-7 ≤ x < 19

[-7, 19)

e) Números mayores que 9 y menores que 5.

Las otras formas de escribir esto son:

5 < x < 9

(5, 9)

A safety regulation states that the maximum angle of elevation for a rescue ladder is 72º. A fire department's longest

Svetradugi [14.3K]

Answer:

110sin(72°) feet

Step-by-step explanation:

In the right triangle with the 110 ft ladder as the hypotenuse, the side opposite the 72° angle represents the maximum height the ladder will reach. The definition of the sine function tells you ...

Sin = Opposite/Hypotenuse

so the Opposite side will be ...

ladder height = (110 ft)sin(72°)

Aaden is 1.75 meters tall. At 11 a.m., he measures the length of a tree's shadow to be 37.65 meters. He stands 32.9 meters away

Ratling [72]

The relationship between Aaden and the tree's height is an illustration of equivalent ratio

The height of the tree is 2.00 meters

At 11 a.m, we have:

$\mathbf{Aaden = 1.75m}$

$\mathbf{Tree\ Shadow = 37.65m}$

$\mathbf{Aaden\ Shadow = 32.9m}$

So, we make use of the following equivalent ratio

$\mathbf{Aaden : Tree = Aaden\ Shadow : Tree\ Shadow}$

This gives

$\mathbf{1.75: Tree = 32.9: 37.65}$

Express as fractions

$\mathbf{\frac{Tree}{1.75} = \frac{37.65}{32.9}}$

Multiply both sides by 1.75

$\mathbf{Tree = \frac{37.65}{32.9} \times 1.75}$

$\mathbf{Tree = 2.00}$

Hence, the height of the tree is 2.00 meters

What do cos and sin mean?

Mademuasel [1]

Answer and Step-by-step explanation:

These two terms (pronounced as Sine and Cosine) are used to solve for the sides and angles of a triangle in Trigonometry.

They are functions revealing the shape of a right triangle.

Sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle.

Cosine is also a trigonometric function of an angle. The cosine of an angle is the relation of the length of the side that is adjacent that angle, to the length of the longest side of the triangle.

Use SOHCAHTOA for this. Work out 'm' in 3sf, I need the working out.

Lady bird [3.3K]

Anwer:3.537m

STEP BY STEP EXPLANATIOND:using SOH CAH TOA

First find the opposite

Represent the opposite with x

Tan 33° =x\10

x=10Tan 33°

x=6.494

To find m

Sin 33°=m\6.494 Sin 33°

m=3.5368

m=3.537meteres
