Answer:
( 0, -10 )
Step-by-step explanation:
the y intercepts is ( 0, -10 ) as u can see in this pic
You divide 1/2 by 2 (1/2 * 1/2) and get 1/4. they each get 1/4 pound
A' : -1, 3
B': 1, 2
C': 1, 5
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.
Answer:
it's 22 I'm pretty sure that it about the miles right?
