after 1 second the ball is 76 feet in the air: after 2 seconds it is 144 feet in the air. Find the height of the function. h(x)=
MArishka [77]
General equation for height, h
h = ut + 0.5gt^2

at t=1s, h = 76 feet
76 = u*1 + 0.5*a*1^2
76 = u + 0.5a

at t=2s, h = 144 feet
144 = u*2 + 0.5*a*2^2
144 = 2u + 2a
72 = u + a

Subtract 2 equations
0.5a = -4
a = -8
u = 80

So the equation,
h(x) = 80t + 0.5*(-8) t^2
h(x) = 80t - 4t^2

Express t:

4t^2=900-p,\\\\t^2=\dfrac{900-p}{4},\\\\t=\sqrt{\dfrac{900-p}{4}}.

This expression gives the  month t in terms of the price p.

Step-by-step explanation: CZ 75B has a firing pin block which makes for a longer SA trigger pull. CZ 75 has the superior trigger. Aren't the magazines different (and not interchangeable) as well? IIRC, the older 75 mags are not easy to find, and can be expensive.Apr 22, 2011
