Answer:
Step-by-step explanation:
hey watch it fatty
4 streamers. There are 4 columns so she will need to connect the columns using 4 streamers
Answer:
The rock will be be 5 meters from ground level at time = 3.713 seconds
Step-by-step explanation:
As we know-
![s(t) = -4.9 * t^2 + v_0t + s_0](https://tex.z-dn.net/?f=s%28t%29%20%3D%20-4.9%20%2A%20t%5E2%20%2B%20v_0t%20%2B%20s_0)
V0 = velocity
S0 = height above ground when thrown
Substituting the given values, we get -
![9 = -4.9* t^2 + 12 * t +32\\-4.9*t^2 +12*t + 23 = 0](https://tex.z-dn.net/?f=9%20%3D%20-4.9%2A%20t%5E2%20%2B%2012%20%2A%20t%20%2B32%5C%5C-4.9%2At%5E2%20%2B12%2At%20%2B%2023%20%3D%200)
As per the formula
![t = \frac{-12+ \sqrt{12^2 -4*(-4.9)*23} }{(2*(-4.9)} \\t = 3.713](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B-12%2B%20%5Csqrt%7B12%5E2%20-4%2A%28-4.9%29%2A23%7D%20%7D%7B%282%2A%28-4.9%29%7D%20%5C%5Ct%20%3D%203.713)
The rock will be be 5 meters from ground level at time = 3.713 seconds
Answer:
See Below.
Step-by-step explanation:
We are given:
![i^{4n+2}](https://tex.z-dn.net/?f=i%5E%7B4n%2B2%7D)
Using exponent properties:
![=i^{4n}\cdot i^2](https://tex.z-dn.net/?f=%3Di%5E%7B4n%7D%5Ccdot%20i%5E2)
Rewriting:
![=(i^4)^n\cdot i^2](https://tex.z-dn.net/?f=%3D%28i%5E4%29%5En%5Ccdot%20i%5E2)
Since i⁴ = 1 and i² = -1:
![=(1)^n\cdot -1](https://tex.z-dn.net/?f=%3D%281%29%5En%5Ccdot%20-1)
1 to any power is still 1:
![=1\cdot -1 = -1](https://tex.z-dn.net/?f=%3D1%5Ccdot%20-1%20%3D%20-1)
