Answer:
Step-by-step explanation:
-2x²=-8x+8 means : -2x²+8x-8
the discrinant of the quadratic equation is : delta = b²-4ac
when a=-2 and b=8 and c= -8
calculate delta = (8)²-4(-2)(-8) ......continu
Answer:
(- 2, 4 )
Step-by-step explanation:
The solution to a system of equations given graphically is the point of intersection of the 2 lines.
The point of intersection is (- 2, 4 )
Thus the solution is (- 2, 4 )
Answer:
Yes, 3 is a primitive root of 7.
Step-by-step explanation:
By definition if primitive root, b is a primitive root of p, where p is a prime, if powers of b includes all residue classes mod p. Here,
mod 7=1
mod 7=3
mod 7=2
mod 7=6
mod 7=4
mod 7=5
And =numbers less than 7 and prime to 7=1,2,3,4,5,6, presents in the residue class of 3 mod 7, this proves 3 is a primitive root of 7.
Answer:
-40
Step-by-step explanation:
f(a) = a³ - a² + a - 1
f(-3) = (-3)³ - (-3)² + (-3) - 1
f(-3) = (-27) - (9) + (-3) -1
f(-3) = -27 - 9 -3 - 1
f(-3) = -40
The answer would be C. The change of Velocity over time. :)
