Marat540 [252]
The probability of hitting the black circle is closer to 0 than it is to 1. because: find area of circle ~ 3.14*r^2
which is 3.14 because the radius squared is 1. so 1*3.14= 3.14
 and the area of the whiteness is 121.
subtract 3.14 from 121 and you get 117.86 
this answer is closer to a 0 probability than the white space. the white space is closer to a probability of 1.

A ball is thrown from a height of 49 meters with an initial downward velocity of 2 m/s. The ball's height (in meters) after t se
horsena [70]

The height of the ball at ground level would be 0 feet.

Set h to 0 and solve for t:

Rewrite the equation as  

-5t^2 -2t +49 = 0

Factor -1 out of the equation to get:

5t^2 + 2t -49 = 0

Use the quadratic formula:

-b +/- sqrt(b^2 -4(ac) / 2a

Where a = 5, b = 2 and c = -49

The quadratic formula becomes:

-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)

Simplify to get :

T = -2 +/-sqrt246 / 10

T = 2.936 and – 3.336

Since the time has to be a positive value t = 2.936 seconds.

Rounded to the nearest hundredth = 2.94 seconds.
