Answer:3
Step-by-step explanation:
Answer:
-(-3) ± √(-3)^2 - 4(2)(-5) / 2(2) (the last choice).
Step-by-step explanation:
Im ignoring the 2^2 in the equation
The equation transforms to
2x^2 - 3x - 5 = 0 (standard form)
So x = -(-3) ± √(-3)^2 - 4(2)(-5) / 2(2)
Answer:
he has atleast 36% left
Step-by-step explanation:
because
Answer:
9 sec.
Step-by-step explanation:
I think you wrote the equations incorrectly. It probably is

If that is true, then 
0 = -16
+ 144t
-16t(t - 9) = 0
t = 0 or t = 9
Answer:
3,5, Minimum
Step-by-step explanation:
y=x²-6x+14
y=(x²-2*3x +3²-3²)+14
y=(x²-2*3x+3²)+14-9
y=(x-3)²+5
a=1
p=3
q=5
a>0 ⇒ vertex is minimum
V(p,q) ⇒ V(3;5)
