Answer:

E= $10^{18}$ Joules

Step-by-step explanation:

1) Olá! Adicionando dados faltantes ao enunciado, como a fórmula dada: $M=\frac{2}{3}log(\frac{E}{E_{0}})\\$ e corrigindo a quantidade de Energia inicial: $10^{4,5}$ Vamos seguir aplicando a fórmula, lembrando das propriedades de logaritmo.

$M=\frac{2}{3}log(\frac{E}{E_{0}})\\9=\frac{2}{3}log(\frac{E}{10^{4,5}})*3\\27=2log(\frac{E}{10^{4.5}})\\log(\frac{E}{10^{4.5}})^{2}=27\\(\frac{E^{2}}{10^{9}})=10^{27}\\E^{2}=10^{27}*10^{9}\Rightarrow E=\sqrt{10^{36}}\rightarrow E=10^{18} Joules$

HELP PLEASE<3 <br> Find the missing angle <br> Btw its trigonometry

ira [324]

Answer:

x = 16.6

Step-by-step explanation:

Since we know the measure of an acute angle (31 degrees) of a right angle triangle, and of the side opposite to the angle (10), and we need to find the measure of the adjacent side "x", we use the tangent function:

$tan(\theta) = \frac{opposite}{adjacent} \\tan(31^o)=\frac{10}{x}\\x=\frac{10}{tan(31^o)} \\x \approx 16.64279$

which rounded to one decimal is

x = 16.6

Two jet planes simultaneously started travelling in opposite directions from the same airport. Four hours later they were 3800 m

alexira [117]

Answer:

Step-by-step explanation:

let the speed of one plane=x

speed of other plane=x+80

time=4 hrs

then 4x+4(x+80)=3800

4x+4x+320=3800

8x=3800-320

or 8x=3480

x=435

speed of one plane=435 m/h

speed of other plane=435+80=515 m/h

Let he walks x hrs

then he take a taxi for 2-x hrs

4x+(2-x)50=31

4x+100-50x=31

-46x=-69

$x=\frac{-69}{-46}=\frac{3}{2}$

so he walks 3/2 hrs=1.5 hrs

travels by taxi=2-1.5=0.5 hrs

distance traveled by taxi=0.5×50=25 miles

What is the value of k in the equation StartFraction k Over 3 EndFraction minus 5 = 34?

12345 [234]

$\huge\text{$k=\boxed{117}$}$

$\displaystyle\frac{k}{3}-5=34$

To find the value of $k$ , we need to isolate it on one side of the equation. Add $5$ to both sides of the equation, then multiply both sides of the equation by $3$ .
