Answer:

h = 1.65 m

Step-by-step explanation:

Me parece que el problema está mal formulado por lo siguiente:

El angulo al que se refiere el problema es 54°  o es 50°  o es 54°,50´

Como resolver el problema en cualquier caso.

Si Elisa y su sombra forman un angulo recto, entonces Elisa, su sombra y la distancia entre la cabeza de Eliza y el final de su sombra forman un triangulo rectangulo. Para el cual entonces solo es necesario buscar la tangente del angulo ( cateto opuesto sobre cateto adyacente) como conocemos el cateto adyacente ( la sombra de Elisa ) calculamos la altura de Elisa (h).

Asumamos que el angulo es de 54°  entonces

tang 54° = 1.3763

tang 54° = 1.3763  = h/1.2

h = 1,3763*1,2  m

h = 1.65 m

De igual manera se procedería si el angulo es de 50° ( en este caso la    tang 50° = 1.1917

Answer:

(x + 1)² = (2x)²

(1 + 1)² = (2(1))²

2² = 2²

(-1 + 1)² = (2(-13))²

(-12)² = (-26)²

Simplify 6x/10x2\6/10x3-60x2<br> A.x-6<br> B.x-4<br> C.4<br> D.x-1
Anna71 [15]

Answer:

  A.  x-6

Step-by-step explanation:

Maybe you want to simplify ...

  ((6x)/(10x^2))/(6/(10x^3 -60x^2))

Invert and multiply. Cancel common factors from numerator and denominator.

  \dfrac{\left(\dfrac{6x}{10x^2}\right)}{\left(\dfrac{6}{10x^3-60x^2}\right)}=\dfrac{6x}{10x^2}\cdot\dfrac{10x^3-60x^2}{6}=\dfrac{6\cdot10x^2}{6\cdot10x^2}(x-6)\\\\=\boxed{x-6}

Advocard [28]

Answer:

The answer is "\frac{5 e^{5\sqrt{x} }}{2\sqrt{x}}".

Step-by-step explanation:

Given:

y = e^{{\color{\red}5}\sqrt{x}}

let

\to  t= 5\sqrt{x}\\\\\frac{dt}{dx}= 5 \frac{1}{2\sqrt{x}}\\\\\frac{dt}{dx}=  \frac{5}{2\sqrt{x}}\\\\

and

\to y=e^t\\\\\to \frac{dy}{dt}=e^t\\

\to \frac{dy}{dt}=e^{5\sqrt{x} }\\

So,

\to \frac{dy}{dx}=  \frac{dy}{dt} \times \frac{dt}{dx}

         =e^{5\sqrt{x} }\times  \frac{5}{2\sqrt{x}}\\\\= \frac{5 e^{5\sqrt{x} }}{2\sqrt{x}}

OR

\to g(x) = 5\sqrt{x} \\\\\to f(x) = e^{(x)}\\\\

Derivate:  

\to f''g' = \frac{e^{(5\sqrt{x})}5}{(2\sqrt{x})}

Last Saturday, the average temperature was 8% higher than the average temperature, 2 Sundays ago, the average temperature 2 Sund
Roman55 [17]

Answer: 1.08T and (1+8/100)T

Step-by-step explanation:

Given: The average temperature two Sundays ago was T degrees Celsius.

Since, last Sunday, the average temperature was 8% higher than the average temperature two Sundays ago.

⇒ The average temperature last Sunday

Since 8%=0.08

Therefore, The average temperature last Sunday

⇒ The average temperature last Sunday

⇒ The average temperature last Sunday

⇒ The average temperature last Sunday

Thus, the right option is 1.08T and (1+8/100)T
