A juggler throws a beanbag into the air with a speed of 1.0 \dfrac{\text m}{\text s} 1.0 s m ​ 1, point, 0, start fraction, star
aivan3 [116]

Answer:

0.102 s

Step-by-step explanation:

Given the following :

Initial speed (u) = 1 m/s

How long does it take the bean bag to reach maximum height?

At maximum height, the final velocity v = 0

Acceleration due to gravity g = - ve (upward motion) =? - 9. 8m/s²

Using the relation:

v = u + gt

0 = 1 - 9.8t

9.8t = 1

t = 1 / 9.8

t = 0.102 s

Use the ratio of a 30-60-90 triangle to solve for the variables.​
Pani-rosa [81]

Answer:

x=12,\\y=6\sqrt{3}

Step-by-step explanation:

In all 30-60-90 triangles, the side lengths are in ratio x:x\sqrt{3}:2x, where x is the side opposite to the 30 degree angle and 2x is the hypotenuse, or longest side, of the triangle.

Since there are 180 degrees in a triangle, the angle on top must be 30 degrees. Therefore, its opposite side is 6 and x=6 in the ratio x:x\sqrt{3}:2x.

Thus, we have:

y=\boxed{6\sqrt{3}},\\x=2\cdot 6=\boxed{12}

Find the coordinates of point p that partition AB in the ratio 2:3 where A (-8,13) and B (2,-2)
Ray Of Light [21]
Check the picture below.

\bf \left. \qquad  \right.\textit{internal division of a line segment}&#10;\\\\\\&#10;A(-8,13)\qquad B(2,-2)\qquad&#10;\qquad 2:3\textit{ from A to B}&#10;\\\\\\&#10;\cfrac{AP}{PB} = \cfrac{2}{3}\implies \cfrac{A}{B} = \cfrac{2}{3}\implies 3A=2B\implies 3(-8,13)=2(2,-2)\\\\&#10;-------------------------------\\\\&#10;{ P=\left(\cfrac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \cfrac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)}\\\\&#10;-------------------------------

\bf P=\left(\cfrac{(3\cdot -8)+(2\cdot 2)}{2+3}\quad ,\quad \cfrac{(3\cdot 13)+(2\cdot -2)}{2+3}\right)&#10;\\\\\\&#10;P=\left(\cfrac{-24+4}{5}~,~\cfrac{39-2}{5}  \right)
