Answer:

<em>La temperatura a las diez de la mañana fue +2°</em>

Step-by-step explanation:

<u>Tasa de Cambio de Funciones</u>

Algunas funciones modelan el estado de una variable respecto al tiempo. La variación de ese estado en cierto intervalo se llama tasa de cambio.

En nuestro problema, tenemos información de los cambios de la temperatura en la ciudad de Londres. Hagamos la secuencia según la historia nos la cuenta:

A las tres de la mañana, la temperatura era -4°. Una hora después la temperatura aumentó 3°, por lo tanto:

A las cuatro de la mañana, la temperatura era -4°+3°=-1°. Dos horas después la temperatura desciende 5° (se obvia el signo). Por lo tanto:

A las seis de la mañana, la temperatura era -1°-5°=-6°

Las cinco horas siguientes, la temperatura aumenta 2° por hora. Queremos saber la temperatura a las diez de la mañana, es decir, cuatro horas luego de la última calculada.

Si aumenta 2° por hora, en 4 horas aumentó 4*2°=8°. Finalmente, la temperatura a las diez de la mañana fue -6°+8° = +2°

A right △ABC is inscribed in circle k(O, r). Find the radius of this circle if:
natta225 [31]

We have been given that a right △ABC is inscribed in circle k(O, r).

m∠C = 90°, AC = 18 cm, m∠B = 30°. We are asked to find the radius of the circle.

First of all, we will draw a diagram that represent the given scenario.

We can see from the attached file that AB is diameter of circle O and it a hypotenuse of triangle ABC.

We will use sine to find side AB.

\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

\text{sin}(30^{\circ})=\frac{AC}{AB}

\text{sin}(30^{\circ})=\frac{18}{AB}

AB=\frac{18}{\text{sin}(30^{\circ})}

AB=\frac{18}{0.5}

AB=36

Wee know that radius is half the diameter, so radius of given circle would be half of the 36 that is \frac{36}{2}=18.

Therefore, the radius of given circle would be 18 cm.

Taylor earns $5 each time she walks her neighbor’s dog. She has already earned $25. Write and solve an equation to find out how
Marianna [84]

Answer:

12 times

Step-by-step explanation:

x is the number of times she has to walk dogs multiplied by 5 dollars she gets each time plus the 25 she started with all equal to 83 because that's how much she needs

5x + 25 = 83

-25 -25

5x = 58

5x/5 = 58/5

x = 11.6

can't walk the dog a 6th of a time so rounded to the nearest while number ti get 12

she has to walk dogs approximately 12 times
