Answer:
Step-by-step explanation:
+ 3 = -z
= -z - 3
Square both sides , we have
2z = ![(-z-3)^{2}](https://tex.z-dn.net/?f=%28-z-3%29%5E%7B2%7D)
2z =
+ 6z + 9
re arranging the equation , we have
+ 6z - 2z + 9 = 0
+ 4z + 9 = 0
This will give a complex roots , solving by quadratic formula
z = -2 +
i , -2 -
i
Answer:
D. x + 2y = 2
Step-by-step explanation:
0 + 2(1) = 2
<span>2.3 seconds.
Let's assign the known values to the equation and solve for t.
h = 16t^2
86.4 = 16t^2
5.4 = t^2
2.323790008 = t
Rounding to the nearest tenth of a second gives 2.3 seconds.</span>
Pythagoras tells us that the diagonal is √(9²+40²) = 41.
