Answer:
I think system 4 has no solution
Step-by-step explanation:
I'm sorry if you get it wrong
458,500 because they are 1000 apart and 500+500=1000
You could use 4(division) sign 25 + 3 (division sign) 15 * 10, ok?
The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds
