Answer:
Step-by-step explanation:
35=-5t²+10t+22
5t²-10t+13=0
disc =b²-4ac=(-10)²-4×5×13=100-260=-160<0
t is imaginary.
So ball never reaches a height of 35 m

Answer:
x = -(1 + 4i)
or x = -1+4i
Step-by-step explanation:
From what we have;
-(x + 1)^2 = 4
(x + 1)^2 = -4
x + 1 = √-4
x + 1 = -4i or 4i
x = -1 - 4i or -1 + 4i
