A soccer ball is kicked and travels 25 meters to the north in 2.5 seconds. At what velocity is the ball traveling?
algol [13]
It would be 10m.
If you divide 25 by 2.5 you get 10, and since we’re using velocity, that’s what we would do.

A rectangular picture has a width of 2/3 foot and a length of 3/4 foot. What is the area of the picture?
Ganezh [65]

Answer:

Area of rectangles: l*b [LENGHT×BREADTH]

Therefore,

3/4 ×  2/3 = Area

We do it as, 3*2/4*3

⇒ 6/12 = area

After simplification, we will get

1/2 = area of rectangular picture

Solve in |R 2cos(2x) +√2 = 0
Alexxx [7]

It is given that:

\begin{gathered} 2\cos 2x+\sqrt[]{2}=0 \\ 2\cos 2x=-\sqrt[]{2} \\ \cos 2x=-\frac{\sqrt[]{2}}{2} \end{gathered}

cos2x is negative square root 2 divided by 2 in the second and third quadrants, so it follows:

\begin{gathered} \cos 2x=\cos \theta \\ 2x=2n\pi\pm\theta \end{gathered}

Here theta is given by:

\theta=\pi-\frac{\pi}{4}=\frac{3\pi}{4},\theta=\pi+\frac{\pi}{4}=\frac{5\pi}{4}

So the solution is given by:

\begin{gathered} 2x=2n\pi\pm\frac{3\pi}{4};2x=2n\pi\pm\frac{5\pi}{4} \\ x=n\pi\pm\frac{3\pi}{8};x=n\pi\pm\frac{5\pi}{8} \end{gathered}
