Answer:
The discriminant of f is 92, and it has no real zeros
Step-by-step explanation:
The discriminant of a quadratic is 
, where the quadratic is in the form 
. The discriminant of this one is therefore:
Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!
Answer:
y = 10.36
Step-by-step explanation:
y - 1.6 = 8.76
add 1.6 to both sides
y - 1.6 + 1.6 = 8.76 + 1.6
y = 10.36
First you need to solve for angle F then you can use 1/2acSinB. If you haven't done this you can also use the Pythagoras theorem and solve for the unknown side once you do that you can just use 1/2 b*h
V = a²h/3
Plugging values in we get 8.67X10^7, or 86,700,000
(-2)^3
12^0
I don't know the rest
