Hello,
<span>
h= -16t^2+185t+10, h = 0 when it hits the ground
16t^2+185t+10 = 0
t = 11.6sec (to nearest tenth)
Hope this helps</span>
4. 2/8 = 1/4
6. 5/10 = 1/2
8. 8/18 = 4/9
10. 6/16 = 3/8
12. 10/12 = 5/6
14. 12/15 = 4/5

Distribute 2 in (i+3) and 4 in (1-i)

Move -4i to another side and 6 to another side. When moving to another side, you'll have to change the sign/operator to opposite (Plus -> Minus, Multiply -> Divide)

For this part, move 6 to divide -2.

Whenever either a numerator or a denominator is in negative, we can pull out the negative in the middle of fraction.
<em>Note that i is the symbol of imaginary number - as defined - i = √-1 </em><em>But for this one, It's just a variable if I assume.</em>
Thus, the answer is i > -1/3
