Answer:20
Step-by-step explanation:
I got it right on my test
Answer:
x = 4
Well basically 20 divided by 5 is 4. which makes this clearly the answer because the slope is 20/x which is being divided. So when you times 5 x 4 you get 20. It all comes together in a way.
Answer:
90.5
Step-by-step explanation:
Velocity is a time-derivative of displacement or the height, in this case.
![s(t)=-16t^2+v_0t](https://tex.z-dn.net/?f=s%28t%29%3D-16t%5E2%2Bv_0t)
![v(t) = -32t+v_0](https://tex.z-dn.net/?f=v%28t%29%20%3D%20-32t%2Bv_0)
At maximum height, the velocity is 0 and the height is 128.
Substitute these values into both equations above,
![0 = -32t+v_0](https://tex.z-dn.net/?f=0%20%3D%20-32t%2Bv_0)
![t=\dfrac{v_0}{32}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7Bv_0%7D%7B32%7D)
From the first equation,
![128 = -16t^2 + v_0t](https://tex.z-dn.net/?f=128%20%3D%20-16t%5E2%20%2B%20v_0t)
Substitute for
.
![128 = -16(\dfrac{v_0}{32})^2 + v_0\times\dfrac{v_0}{32}](https://tex.z-dn.net/?f=128%20%3D%20-16%28%5Cdfrac%7Bv_0%7D%7B32%7D%29%5E2%20%2B%20v_0%5Ctimes%5Cdfrac%7Bv_0%7D%7B32%7D)
![128 = -v_0^2/64 + v_0^2/32](https://tex.z-dn.net/?f=128%20%3D%20-v_0%5E2%2F64%20%2B%20v_0%5E2%2F32)
![128=\dfrac{v_0^2}{64}](https://tex.z-dn.net/?f=128%3D%5Cdfrac%7Bv_0%5E2%7D%7B64%7D)
![v_0^2=8192](https://tex.z-dn.net/?f=v_0%5E2%3D8192)
![v_0=64\sqrt{2}=90.5](https://tex.z-dn.net/?f=v_0%3D64%5Csqrt%7B2%7D%3D90.5)
