The riddle given by Dr. Watson to Sherlock Holmes is:

217 is to 335
896 is to 543
345 is to ____

We need to find the missing number of the third pair of the riddle. This is a ratio and proportion problem.

217/ 335 = 896/ 543 = 345 / x

The value of x is 209.

F(4) = ______<br> If g(x) = 2, x = _____
disa [49]

Answer:

<h2>f(4) = -10 </h2><h2> </h2><h2>x = 0 </h2>

Step-by-step explanation:

From the graph attached,

For x = 4,

Value of the function will be,

f(4) = y value at x = 4

f(4) = -10

Similarly, for y = g(x) = 2,

x value of the function will be,

x = 0

For which g(0) = 2

Therefore, for x = 0 value of the function will be 2.

g(0) = 2

En Colima se lleva acabo la conferencia sobre la energética eólica a la cual asistieron 120 representantes de Latinoamérica y Su
andriy [413]
The first thing we must do for this case is to see how many representatives from each country attended.
 We have then:
 Argentines = (1/6) * (120) = 20
 Chileans = (1/5) * (120) = 24
 Bolivians = (1/4) * (120) = 30
 Venezuelans = (1/4) * (120) = 30
 Adding we have:
 20 + 24 + 30 + 30 = 104
 Therefore the number of Americans is:
 120-104 = 16
 Answer:
 16 Americans attended the wind energy conference

Find the distance traveled by a particle with position (x, y as t varies in the given time interval. x = 3?sin2 t, y = 3?cos2 t,
ANTONII [103]
Assuming the particle's position is given by

\begin{cases}x(t)=3-\sin2t\\y(t)=3-\cos2t\\0\le t\le4\end{cases}

then the distance traveled over the interval is

\displaystyle\int_{t=0}^{t=4}\sqrt{\left(\dfrac{\mathrm dx(t)}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy(t)}{\mathrm dt}\right)^2}\,\mathrm dt
=\displaystyle\int_0^4\sqrt{(-2\cos2t)^2+(2\sin2t)^2}\,\mathrm dt
=\displaystyle\int_0^4\sqrt{4\cos^22t+4\sin^22t}\,\mathrm dt
=\displaystyle2\int_0^4\mathrm dt
=2(4-0)=8
